Acer Aspire Switch 12 noisy LCD backlight?

Greetings, Got my brand new Acer Aspire Switch 12 the other day. I'm very satisifed with the form factor and with the device in general. Except for one thing. There is audible amount of noise coming from my unit when the backlight is set between 0% and 100%. The noise seems to emanate just under the "Acer" logo. This noise goes away when i set the backlight to 0% or to 100%. And it seems to be the loudest if i set the backlight to about 50% It is not very obvious but i can definitely hear it in a quiet room. Kind of defeates the whole point of a fanless design if you ask me. I think the noise is coming from the capacitors or coils in the backlight regulator circutry. I would like to know if this is a general problem with this model or is this just a problem with my unit. Fellow Aspire Switch 12 owners, do you have the same issue with your unit? Acer admins, is this a known problem with this model? I have to know, i have to decide whether i'm going to replace the unit, return the unit or just stick with it. I bought it from amazon.es.Part number of my unit: NT.L7FEB.004

mkatic,
I do not see anything in the documentation that talks about that issue, you can contact Acer technical support in your area to see what your options are, or you can seek them through Amazon; I believe that this might be their return policy if it helps steer you in the right direction.

Acer Aspire Switch 10E - unable to boot, no keyboard

Hello everyone,
I have recently bought an Acer Aspire Switch 10E to do my terrain work, and would love to be able to run Linux on it. I'm running into one problem after another though (most likely because some things aren't officially supported yet, but I was wondering if anyone had any similar experiences who might be able to help me out. To cut the long story short, from my own experience, I'm sure Linux can run on this.
In any case, the machine features a quad-core Intel Atom CPU (which should work AFAIK), with Intel HD graphics (which should also work flawlessly AFAIK). It also features a Realtek RTL8273BS WiFi network card (haven't got to trying it out, but my guesstimate is that it requires some proprietary firmware, since it didn't work on Ubuntu live). It has a 1280x800 touchscreen (which worked flawlessly on Ubuntu live), and a dockable keyboard (now that one boggles me). This is just a quick "tldr" version of what the machine is supposed to be. It's basically a 64-bit x86-compatibile tablet PC with a dockable keyboard and which shipped with Windows 8.1.
Okay, so first things first. The Acer Aspire Switch 10E has a 32-bit UEFI, and there is no possible way of booting an OS (live or otherwise, Linux or otherwise) which only has a 64-bit EFI image. There is no legacy BIOS on the motherboard, so (to whom it may concern), don't even bother with online tutorials that tell you to switch to legacy BIOS, as there is no way to enable it. On the other hand, a valid 32-bit EFI image will boot, even in Secure Mode, so don't bother disabling that either. In other words, there is absolutely no need to change anything in the UEFI setup in order to boot Linux, apart from adding your 32-bit EFI image to a trusted list.
Thus, in order to boot any live Linux media, it is (TTBOMK) required to either generate a working 32-bit EFI image, or use an existing one. It took me a while to figure that out, on top of the time to figure out how to generate my own 32-bit EFI image, without breaking something. Bear with me here - this is the first machine I ever owned that features an UEFI, let alone an UEFI without legacy BIOS.
Here is the stuff I found, which I was able to use to get to this point:
UEFI GPT Arch Linux USB (bootx64.efi and bootia32.efi) - Taylorbyte.com
Acer Aspire Switch 10 can't boot 14.04 LTS - Ubuntu Forums
From Ubuntu forums, I learned about this and this, both of which have bootable 32-bit EFI images, which work on Ubuntu live. Those, however, did not work with Arch Linux, for some reason, so I generated my own EFI images from the tutorial found on Taylorbyte.com. Not absolutely sure if I did it right however, since the tutorial seemed a bit dated, but it did get me into the basics I needed.
So, I now have a bootable USB drive with Arch Linux installed on it, with both 32-bit and 64-bit EFI images. My Acer Aspire 10E recognises the 32-bit EFI image and boots into GRUB loader from it, which asks me whether to boot into Arch Linux or Arch Linux Fallback. At this point, my keyboard still works, and I can choose either.
However, as soon as I choose Arch Linux to boot, it complains about being unable to boot from "UUID=<my USB's UUID>", and drops me into a boot console. The cursor blinks, but the keyboard input is not recognised at all.
I have recompiled the kernel for my live Arch USB (via makepkg -o and makepkg -e) as stated on the Ubuntu forums (setting HID_MAX_USAGE = 65536 in a certain header file in the kernel sources), but it didn't do much. The kernel still compiles, so I guess that's a plus.
Without keyboard, I am unable to install Arch on this machine, and I'm currently stuck with this error, which I'm not sure what to make of. I have never stated any UUID's while configuring my Arch live USB, so I suppose something is detecting it automatically, thus preventing Arch from booting (no idea what it could be, though).
So to conclude, I need help with booting Arch live USB on this machine, as well as getting keyboard to work. I have read here and there some people had some success with either Arch, Fedora or Ubuntu, and I've seen (32-bit) Debian 8.1 installer boot normally - without keyboard or wifi, though.
Any help regarding this would be very much appreciated.

Hi Marc, Thanks for the swift response. I'm not sure if Acer (Philippines) will be able to give the necessary support since they are only selling the Switch 10 (not even Switch 11! So backwards!) . I don't mind reinstalling the file from time to time as long as it will fix the problem asap. Would it be possible to know how often you reinstalled the exe file to fix the problem? One more thing, the only thing that's hindering on buying the Switch 12 are problems like these (since we don't have the tech support yet). Would it be possible for you to send me the fix for the keyboard problem? Thank you very much! ++ How's the experience when you are using it on your lap, let say when travelling on a plane ? Is the built stable enough that it won't stumble that easily?

Somtime my Acer Aspire Switch 11 cant turn on properly

There are times that my Acer Aspire Switch 11 cant turon on properly I tried the following but still it wont turn on: 1. Click the power button2. Click and hold the power button for 10 to 15 seconds It only opens when I charge it and hold the button for 10 to 15 seconds. However the Acer is not lowbat (almost 40%) This always happens everyday since I use the laptop everyday Hope any can help with this Thanks!

How did you leave it when last used? Did it go to sleep or did you do a shutdown (or even hibernate)? If we can figure out what triggers the bad behavior then we can perhaps come up with a solution.

Acer Aspire Switch 10 e keyboard dock problem

Hi. I have this brand new Acer Aspire Switch 10 E which I just bought last month. I'm now having problems with the keyboard and the dock as when I connect the tablet/screen to the dock, the keyboard is not detected. It recognizeswhen I dock the tablet but it doesn't detect te hard drive nor the keyboard. Sometime, after a long while, it detects the keyboard and the hard drive but only for a few seconds then it disappears again. Other times, it just flips continually from working and then not working. The problem is so sudden. I would jokingly note that whenever I search for solutions to the keyboard problem, it very briefly fixes itself. On a serious note however, I do not know what causes this malfunction nor do I know what fixes it. As stated above, the problem is so sudden. I have been very, very careful with the use of my laptop including in the removal and docking of the tablet. I have inspected the docking pins, and physically, they look perfectly fine. The problem occurs even the tablet has been connected and left undisturbed for continuous periods of time. This has led me to believe that the problem could be software based and not hardware. I am also open to the possibility that it could be heat affecting the docking pins (heat can cause connection issues and this isn't the first time I have encountered one, nor the second) but like I said, the docking pins work perfectly and remain constantly in contact witch each other. As I have postulated that the problem is software based, I have gone through the hassles of searching for possibble drivers for the dock/keyboard. Unfortunately, (this might be due to the Aspire Switch 10 E being a fairly new model) there were no keyboard drivers on the Acer support page for the Aspire Switch 10 E. In my search, I encountered a video for the Aspire Switch 10 keyboard to fix the problem, a driver update for the Switch 10, NOT the Switch 10 E. I have tried the solution and it still does not work. I am not a fan of forums and if I am, I am usually just a reader kind of person. But in the light of recent events and the fact that there are virtually NO questions or posts about this brand new model of laptop, specfically the Aspire Switch 10 E, I have taken the responsibility of raising this question in the hopes that a knowledgeable person may provide assistance and that the others of my kind (the Aspire Switch 10 E users) may be enlightened as well. I would sincerely appreciate the assistance. God bless. TL;DR: Aspire Switch 10 E detects docking but keyboard and hard drive are inconsistently not working. Help. Reposted this topic on the laptops forum because I realized I posted the first one in desktops.

Hi, I have a similar problem. Sometimes after waking or after removing or reataching the keyboard it becomes unresponsive. But if I then restart the computer it is fine. I think, in my case at least, it can not be due to just a bad connection, as otherwise restarting it would not change anything. Also, I don't think it is something that has been fixed as it is quite a recent purchase and I have recently updated windows and drivers. The whole reason for choosing this pc was the ease with which it converts between tablet and laptop mode so any advice would be very welcome. Thanks,Tom

Acer Aspire Switch 10 not turning on

Hey there, I have an Acer Aspire Switch 10 that will not turn on. I was using it to browse the web earlier today when I heard a clicking noise and it suddenly shut off. When plugged in, it recognizes that it is being charged, but it does not turn on when I press the power button. Please help! Thanks,Ben

In this case, remove the battery from the computer (if feasible) and connect the computer directly to the power adapter. Now, check if it turns on. If it turns on, then there may be some issue with your battery. To confirm this, you can consider using another battery and see if that resolves the issue. If the issue still persists, then there may be some hardware issue with the computer and you need to take it to nearest Acer service center for further assistance. To do this, the following link can be helpful:

ACER ASPIRE SWITCH 10 SHUTS DOWN and WONT TURN ON

I got my Acer Aspire Switch 10 just 2weeks ago. Everything seems fine until yesterday.
I was using the unit, charger plugged in (blue indicator light present), then it just shut down. I tried restarting it and it wont open. The monitor was becoming warm.
Now, I plugged it in (orange indicator light present), it is just a blank screen. I tried pressing the power button for about 30 seconds then press the power and volume down button (I read it somewhere), but the monitor just blinked black and gray many time.
Can someone help me with this please. Desperate here. Thank you!!

Sorry to hear that you have issues with new windows tablet,If you are using Aspire SW5-01, you will find a reset pinhole between Microphone and MicroSD card slot. Insert a paperclip into the hole and press for four seconds to reset the tablet If the power indicator is blue steady then the computer is fully charged and plugged in.Amber Steady, then the computer is charging and plugged in.If Amber Blinking, then the battery is critically low or abnormal batteryIf the indicator is Off, the computer is off.

Re: Acer Aspire Switch 10 - Proprietary Charging Port to micro-USB adapter

I have a high power power bank capable of charging via both usb and 19v. Included were adapter cables that fit many devices that don't charge via usb. However none fit an acer switch 12.Any ideas?

Radio Shack, if you can still find one, has adapter tips that fit. Make sure your 19V supply is putting out the appropriate wattage, though I expect if it's designed to power a laptop it'll have plenty.

Acer Aspire Switch 10 - USB Boot / Windows 8.1 installation from USB

Hi
I recently bought Switch 10. As it has only 32GB SSD splited in 24GB of windows partition and 8GB for Recovery I tried to merge those partition to get rid of Recovery and have only one SSD partition. Longbstory short, I failed and got a bluescreen, then a reboot and now I have this:
http://i.imgur.com/NmAkhgO.jpg
I have Windows 8.1 from official Microsoft website, I have orginal CDkey (not OEM from Acer). The version I downloaded is a 32/64bit installer (I think, but it may be only 32bit)
I was trying to set up BIOS by myself, but it always puts me to blue screen of windows (with error 0000225).
I provide screens of BIOS with default settings: http://imgur.com/a/jtyN2
I prepared pendrive from an .iso image with a program called Rufus, partitioning system GPT.
Then I changed BIOS settings to allow non secure boot and to boot first from USB HDD, and while booting I hit F12. But still I get that: http://imgur.com/yE48diG
- What I would like to do? Be able to start Windows 8.1 installator, clear all SSD partitions and make only one 32GB with windows.
- What I need? Help, becouse I cant start boot from USB and run Windows 8.1 installator.

This is NOT correct info. Who in their right minds thinks that Windows' own installation media creator cannot create the proper media to install their own software. That's just idiotic. HERE is the correct info: First, you must be using 32bt installer. Switch 10 does not support 64bit. (At least mine does not) You can check the efi\boot folder for the file. bootx64.efi is incorrect. It should be bootia32.efi GPT or MBR SHOULD NOT MATTER. I personally know MBR works fine. I don't bother with GPT since I am no where near 2TB, nor can it ever be added. Drive must be FAT32 Add supervisor PW to UEFI to enable Secure Boot changes. Disable Secure Boot Change your boot order to reflect USB HDD first. After you hose your system and want to put it back, good luck with that. I can point you a direction on this but I haven't successfully done it yet myself, so I don't even say it is the 'right' direction. I wiped my partitions, and it's a BAD IDEA at this point in Win10 developement IMHO. Anyways, 8.1 with Bing is a different license than 8.1. You cannot DL 8.1 with Bing in any shape or form from MS. And your embedded key will not activate ANYTHING on the list in MS media creator. There is ONE guy who has UL the factory image as a torrent. It's the UK version, but it works and you can change the lanuage pack afterwards (I think. it wasn't annoying enough for me to try it yet) I couldn't seem to get RUFUS to create a UEFI from the guy's image. My solution was to use MS Media Tool to DL and create a 32bit, 8.1 usb drive. Once I verified it would indeed boot the machine, I then deleted all VISIBLE files from it and replaced them with the files from the UK ISO. DO NOT FORMAT. The whole point is to have the hidden system files and MBR intact. Just delete and then copy paste. At this point you should be able to boot and install windows. Then go DL the Master Installer from acer and it'll install MOST of the drivers. I still cannot get my built in sound to work again. Anybody that does, help would be much appreciated.

How can I hibernate my Aspire Switch 10E?

Hello, I have a recently purchased Acer Aspire Switch 10 E. Since I purchased it I have not had the option to hibernate the computer. I know that the OS, Windows 8.1, by default often does not have the option to hibernate, but even when I go to control panel, power options and change settings that are currently unavailable I do not have the option to hibernate. I have updated windows and drivers, went to the registry to check it allows for hibernation and used some command line tools but still no option. I was begining to think that perhaps the device is not capable of hibernation as it seems others with this pc have the same issue, but I found that in the advanced power option the default for critcal power action is to hibernate. As I use several programs on this pc while travelling and meeting clients, it is important that I can retain work in progress over long periods where putting it to sleep will just loose the battery and restarting work after a full shutdown is impractical so any advice would be gratefully recieved. Thanks.Tom

tomeq,
Try this:
Open Power Options by swiping in from the right edge of the screen, tapping Search (or if you're using a mouse, pointing to the upper-right corner of the screen, moving the mouse pointer down, and then clicking Search), entering Power options in the search box, and tapping or clicking Power options.
Tap or click Choose what the power button does and under Shutdown settings, select Hibernate (if it's available).

Acer Aspire E5-473-35TX or Acer Aspire V15 Nitro Black Edition VN7-571G-73ZJ ?

Boy, those are two very different machines! The first one is very handy if you are carrying the laptop with you most of the time, especially if you are switching between carrying it, using it as a laptop and using it as a tablet fairly often. The detriment is that the screen is small, only 10 inch. The second one is a lot more powerful and larger, but it will be more of a hassle to carry (you will want a backpack or briefcase). It's better suited if you are traveling between locations and want to set it up for extended use at each destination. You are going to be less likely to want to pull it out for ten minutes of quick web surfing.

[HOWTO] Installing Arch Linux stable release on Acer Aspire One 522

[This is a work on progress and my first howto ever]
These steps will teach you how to install ArchLinux x64 stable release (currently 2010.05) on Acer Aspire One 522 from an existing ArchLinux (your desktop computer)
As you need a 2.6.37+ kernel to make networking work on the AO522, installing stable release as is won't work.
This Howto borns with the intention to address this problem.
You need to be familiarized with Linux internals to follow this howto.
(Expect this howto to become useless with new stable releases of ArchLinux.)
Remember to make a backup of your Windows 7 Starter system before installing ArchLinux.
I did a full raw copy of the harddisk by using systemrescuecd, an external harddisk and dd utility:
Just boot with systemrescuecd
Mount your external harddisk on /mnt/floppy for example
Clone harddisk with: dd if=/dev/sda |gzip -c > /mnt/floppy/ao522.img
This process took me a lot of time since my external harddisk is USB-1 (almost an entire evening)
Result image was about 22GB size
This image will restore partition table, boot sector and all data if things go wrong.
I followed some of the steps from this guide: https://wiki.archlinux.org/index.php/In … ting_Linux
If you have some Gentoo Linux experience you will find those steps really familiar.
You will need 2 USB pendrives or similar storage options.
One is needed to boot into your netbook, and the other to store our custom archlinux build.
Making an updated ArchLinux system
1) Make a local dir on your existing linux system
# mkdir ./newarch
2) Install pacman database on it
# pacman -Sy -r ./newarch
3) Install base system
# pacman -S base -r ./newarch
4) Let's chroot inside
# cp /etc/resolv.conf ./newarch/etc/
# cp /etc/pacman.d/mirrorlist ./newarch/etc/pacman.d
# mount -t proc proc ./newarch/proc
# mount -t sysfs sys ./newarch/sys
# mount -o bind /dev ./newarch/dev
# chroot ./newarch /bin/bash
5) Edit configuration files
# nano -w /etc/rc.conf
# nano -w /etc/hosts
# nano -w /etc/mkinitcpio.conf
Forget /etc/fstab for now since you don't know what partitions to use yet
6) Generate kernel image
# mkinitcpio -p kernel26
7) Generate locales
# nano -w /etc/locale.gen
# locale-gen
8) Make a tarball with our custom ArchLinux
# exit
# umount ./newarch/proc
# umount ./newarch/dev
# umount ./newarch/sys
# tar -cvpf newarch.tar ./newarch
9) Copy this tarball to an USB pendrive or external harddisk
10) Boot your netbook with a Linux bootable USB stick (I used systemrescuecd, and remember to pick the x64 bit kernel at grub screen)
You can use any linux distribution with usb bootable options. I suppose ArchLinux works too
To install SystemRescueCD on an USB stick follow this tutorial -> SystemRescueCD on usb stick
Insert the usb stick on your netbook, switch on, hit F2 to enter BIOS menu, and choose to boot from USB as first option. Save and Exit.
You should be booting into SystemRescueCD without any problem.
After initialization you will end in a root prompt.
11) Let's partition the disk
You will find 3 partitions if this is your first time:
/dev/sda1 2048 29362175 14680064 27 Hidden NTFS WinRE
/dev/sda2 * 29362176 29566975 102400 7 HPFS/NTFS/exFAT
/dev/sda3 29566976 488397167 229312696 7 HPFS/NTFS/exFAT
My recomendation is to leave sda1 and sda2 intact, as they have the recovery information to restore Windows 7 Starter
You have plenty of space with sda3, about 230G.
So run fdisk/cfdisk and delete /dev/sda3
Now create a 100M partition for boot
Now create a Extended partition with all the space left
Now create a 1GB logical partition for swap
Now create a 10-15 GB logical partition for root system
And finally a logical partition for our home partition with all space left
Your partition table should look like this:
/dev/sda1 2048 29362175 14680064 27 Hidden NTFS WinRE
/dev/sda2 * 29362176 29566975 102400 7 HPFS/NTFS/exFAT
/dev/sda3 29566976 29771775 102400 83 Linux
/dev/sda4 29771776 488397167 229312696 5 Extended
/dev/sda5 29773824 31821823 1024000 83 Linux
/dev/sda6 31823872 63281151 15728640 83 Linux
/dev/sda7 63283200 488397167 212556984 83 Linux
12) Create filesystems
I choosed ext2 for boot, and reiserfs for root and home partitions.
# mke2fs /dev/sda3
# mkreiserfs /dev/sda6
# mkreiserfs /dev/sda7
# mkswap /dev/sda5
13) Mount partitions
# mkdir arch
# mount /dev/sda6 arch
# mkdir arch/boot
# mount /dev/sda3 arch/boot
# mkdir arch/home
# mount /dev/sda7 arch/home
14) Copy our custom ArchLinux build on it
# mount /dev/sdb1 /mnt/floppy (for example)
# cd arch
# tar -xvpf /mnt/flopy/newarch.tar
15) Configure /etc/fstab
Mine is as follows:
devpts /dev/pts devpts defaults 0 0
shm /dev/shm tmpfs nodev,nosuid 0 0
/dev/sda3 /boot ext2 defaults 0 1
/dev/sda6 / reiserfs defaults 0 1
/dev/sda7 /home reiserfs defaults 0 1
/dev/sda5 swap swap defaults 0 0
16) Chroot in your new system
# mount -t proc proc ./proc
# mount -t sysfs sys ./sys
# mount -o bind /dev ./dev
# chroot ./ /bin/bash
17) Install grub
# grub-install
Edit /boot/grub/menu.lst to suit your needs
Mine looks like this:
timeout 5
default 0
color light-blue/black light-cyan/blue
title Arch Linux
root (hd0,2)
kernel /vmlinuz26 root=/dev/sda6 ro
initrd /kernel26.img
title Arch Linux Fallback
root (hd0,2)
kernel /vmlinuz26 root=/dev/sda6 ro
initrd /kernel26-fallback.img
title Windows 7 Recovery
rootnoverify (hd0,0)
makeactive
chainloader +1
As you see, you can restore Windows 7 Starter from Grub.
18) Change root password
# passwd
19) Add a regular user account
# useradd -G video,audio,users -m username
# passwd username
20) You're done!
# exit
# cd ..
# umount ./arch/proc
# umount ./arch/dev
# umount ./arch/sys
# umount ./arch/boot
# umount ./arch/
# reboot
Remove the usb stick from your netbook.
If all went ok, you will be inside your new stable and updated ArchLinux system

Using acpid to achieve the following:
- Change screen brightness when operating in battery mode
- Power off when the power button is pressed
- Suspend when the lid is down
- Reduce CPU frequency speed to maximize battery usage
Remember that system suspend is only supported by ati free driver xf86-video-ati
1) Install acpid daemon and cpufrequtils
# pacman -S apcid cpufrequtils
2) edit acpid handler script
# nano -w /etc/acpi/handler.sh
Change the following section:
ac_adapter)
case "$2" in
AC)
case "$4" in
00000000)
echo -n $minspeed >$setspeed
#/etc/laptop-mode/laptop-mode start
00000001)
echo -n $maxspeed >$setspeed
#/etc/laptop-mode/laptop-mode stop
esac
*) logger "ACPI action undefined: $2" ;;
esac
for:
ac_adapter)
case "$2" in
ACAD)
case "$4" in
00000000)
echo 3 > /sys/devices/virtual/backlight/acpi_video0/brightness
cpufreq-set -c 0 -f 800Mhz
cpufreq-set -c 1 -f 800Mhz
00000001)
echo 9 > /sys/devices/virtual/backlight/acpi_video0/brightness
cpufreq-set -c 0 -f 1000Mhz
cpufreq-set -c 1 -f 1000Mhz
esac
*) logger "ACPI action undefined: $2" ;;
esac
Make sure you changed AC) for ACAD)
Now change this other section:
button/power)
#echo "PowerButton pressed!">/dev/tty5
case "$2" in
PWRF) logger "PowerButton pressed: $2" ;;
*) logger "ACPI action undefined: $2" ;;
esac
with:
button/power)
#echo "PowerButton pressed!">/dev/tty5
case "$2" in
PWRF) poweroff ;;
*) logger "ACPI action undefined: $2" ;;
esac
Change:
button/lid)
#echo "LID switched!">/dev/tty5
logger "ACPI group/action undefined: $1 / $2"
for:
button/lid)
pm-suspend && /etc/rc.d/network restart
logger "ACPI group/action undefined: $1 / $2"
Network restart is used because wlan0 will disconnect from AP after some time. You can try using iwconfig wlan0 essid <ap> key <key> instead of the network script, but haven't tested it myself.
3) Start acpid and load modules
# modprobe powernow-k8
# /etc/rc.d/acpid start
Add "acpid" to DAEMONS in /etc/rc.conf to start on boot
Add "powernow-k8" to the modules sections on /etc/rc.conf to load at boot
Stopping system freezes due to ethernet driver
The only way people have found to avoid freezes is by blacklisting atheros kernel drivers.
To do it at boot just edit /etc/rc.conf and change the MODULES line as this:

Reboot and you're done, but remember to not press the Wifi key, because it can freeze your system.
Correctly starting wireless at boot
I've found that standard scripts wont load properly my wireless lan. It gave an error telling you to use the WIRELESS_TIMEOUT variable and such.
To solve this, edit /etc/rc.d/network script and change the wi_up function by adding a second iwconfig command like this:
wi_up()
eval iwcfg="\$wlan_${1}"
[[ ! $iwcfg ]] && return 0
/usr/sbin/iwconfig $iwcfg
[[ $WIRELESS_TIMEOUT ]] || WIRELESS_TIMEOUT=2
sleep $WIRELESS_TIMEOUT
/usr/sbin/iwconfig $iwcfg
bssid=$(iwgetid $1 -ra)
It will do the trick and will start at boot correctly. This is not a solution but a fix.
Adjust Touchpad to disable false taps
What I did here is defining an area to be ignored. This area are 3 rectangles on top, left and right of the touchpad.
This means you can write and press space without having the cursor click out of the window and such.
# synclient AreaLeftEdge=150
# synclient AreaRightEdge=1300
# synclient AreaTopEdge=300
Also, add it to your /etc/X11/xorg.conf.d/10-evdev.conf:
Section "InputClass"
Identifier "evdev touchpad catchall"
MatchIsTouchpad "on"
MatchDevicePath "/dev/input/event*"
Driver "evdev"
Option "AreaTopEdge" "300"
Option "AreaLeftEdge" "150"
Option "AreaRightEdge" "1300"
EndSection
You can play with those values. They just work for me.

Install Windows 8.1 Pro on Acer Aspire V Nitro VN7-591

Hi forum, I recently bought the Acer Aspire V Nitro VN7-591 and I noticed that it only comes with the Core Edition of Windows 8.1. As I need some of the features of the Windows 8.1 Pro Edition (joining domains, remote display etc.) I would like to upgrade the System to Windows 8.1 Pro. I still have an unused Pro retail key (no OEM, no Upgrade Pack) here so at the moment I'm downloading the ISO for Windows 8.1 Pro. But prior to installation I would like to make sure that everything works out fine and I don't run intro problems. First of all: is there anything I need to save from the old OS (except from the recovery partition- I already saved that to a USB drive using the recovery program provided by Acer)? Do I have to know my Product Key (using for example a key viewer software) just in case? Do I have to disable secure boot in BIOS? Second: can I just install Windows 8.1 Pro using my ISO and installing the drivers from the Acer support website? Drivers should still work, right? Third: if I ever want to switch back to Windows 8.1 Core (the OEM edition) do I just use the USB pen drive created with the acer recovery tool? Will my retail Windows 8.1 Pro Key be usable again if I switch back to the original OS? Sorry for asking that many questions but I just have to make sure that it runs trough right in the first place because I need the Laptop to function. What would be your standard procedure to this kind of "problem"? Thanks in advance and with regards,The_DJ Edit:I might have forgotten to mention that I want to do a clean reinstall without all the bloatware from Acer. That's why I'm using the Windows 8.1 Pro "Vanilla" ISO and if I ever want to switch back to core use the Windows 8.1 Core "Vanilla" ISO. Is that possible or would I have to use the recovery partition saved to my USB drive?

Changing the Operating System may cause driver conflicts. The compatible drivers for Windows 8.1 will not be available in the website for this laptop. Hence, some of the features on the laptop might not work after changing the OS. 1: Since you have already created the USB recovery media from the laptop, you do not have to copy anything else other than this. Make sure you you backup all files before installing the OS, as it will remove all data from the laptop. I see that, you have the unused Pro retail key for the OS, hence, you do not have to have the OEM product key. You need to use the product key for Windows 8.1 Pro to activate it, not the Acer OEM product key. In the BIOS, select BOOT tab. Select BOOT MODE as Legacy Mode instead of UEFI.Disable Secure Boot. Under Boot Priority Order, you need to select 1 as CD/DVD (if you are using disc), or USB FDD or USB HDD (if you are using USB drive) to install Windows 8.1 Pro. Then press the F10 key and select "Yes" to save the changes in BIOS. ->You an install Windows 8.1 Pro using my ISO and installing the drivers from the Acer support website. As said before, there may driver conflicts. -> If you want to switch back to Windows 8.1, you may use the USB reovery drive (which created you have created from the recovery partition). When you do this, the Windows 8.1 Pro and it's product key will be removed from the laptop and the factory shipped OS, drivers, apps (and the OEM product key) will be installed automatically. You do not have to use the Windows 8.1 Pro key with Acer OEM USB reovery media. -> You need to do a clean install using the USB recovery drive to install factory shipped Windows on the laptop.

Firefox Slow Even When Offline on Acer Aspire One ao751h-1145

I have a 2gb RAM, 1.33 Ghz Intel Atom CPU Z520, and a fresh install of Windows 7 Ultimate on my Acer Aspire One ao751h-1145. I have no viruses and no programs running in the background. I've installed and uninstalled various versions of Firefox (4, 11, 12) and even upon a fresh install before I edit preferences, bookmarks, or add-ons, the PROGRAM ITSELF is super slow. It isn't using any more RAM or processer speed that it should, however. What it does: Menus are slow to open, scrolling is jumpy, and switching from tab to tab takes like 2 seconds. Internet Explorer 8 works just fine, as do all other programs on the computer. Also, it works fine in Safe Mode. I can't find anything regarding this issue online. Help!

Thanks for reply. But, drivers are up to date. However, I found on this page (https://support.mozilla.org/en-US/kb/how-do-i-upgrade-my-graphics-drivers) that I might want to disable hardware acceleration. I did that through the options menu and Firefox is "usable," but still not what I'm used to on other computers and still not as fast as IE on the same computer. Since turning of the hardware acceleration helped, what else can I do along the same lines to speed it up more? I know a 1.33GHz processor is plenty fast enough to run only firefox by itself. The computer I'm on now (my non-netbook) runs at 700MHz when on batteries and has no performance issues. I hope I can get it because I don't want to use another browser! :(
