Tecra A9 - Network doesn't work after wake up from sleep/hibernate mode

I have TECRA A9 and it work fine but I found that when the laptop go to sleep/hibernate mode and after return to work on the laptop the network not working.
It keep the light on but there is no network and to solve it I need to restart the laptop.
Any help please.
Regards.

This is a known issue so have a look on this website:

Update the BIOS and then it will work.

X1 Carbon Touch: Blue screen or error messages after wake up from sleep/hibernate mode

Sleep function is not consistent... While it works most of the time; yet the other times are frustrating when the result is reboot, reboot with blue screen or hang!

Hey @mambu ,
Welcome to the HP Forums!
I understand you're having issues with screen brightness and blank screens since updating your dv6 notebook to Windows 8.1.
Looking at the available drivers for your notebook you will find there are no drivers for Windows 8 or Windows 8.1 for this notebook. This will drastically affect how the graphics card (GPU) functions in this Windows environment.
Your notebook has a feature called switchable graphics. In order for switchable graphics to function properly you must use drivers provided by HP directly for the graphics cards to work properly. Since HP didn't release drivers for Windows 8 or 8.1 for the GPU setup on your notebook the brightness functions may not work and you may notice issues with the display. It would make sense that this issue is present after sleep or hibernation because the drivers need to be initialized and are encountering errors because they are not the correct drivers, or are generic Microsoft drivers and cannot communicate properly..
The only professional suggestion I can make is that you reinstall an operating system that your notebook hardware has available drivers for. Windows 7. Sorry for the bad news.
Thanks!

[Solved] Network doesn't work after hibernate?

Hello! This is my first legit Linux install so excuse me if I'm a bit slow. I installed Arch last night and everything went smoothly. However, after I tested out hibernate on my machine, the network doesn't seem to work. Just prior to the hibernate, I installed Pidgin and Skype but they worked alright, so I think that the hibernate caused a problem on eth0.
I have an Asus P8Z68-V Pro motherboard with an Intel 82579V Gigabit Ethernet Controller that's using the e1000e driver. Running "dmesg | grep e1000e" says that it is up.
I'm not entirely clear here, but from reading, I think that I have several ways of connecting to the network, including network, dhcpcd, networkmanager, and wicd. I am using wicd so I did the following (or at least I think I am only using wicd):
#rc.d stop network
#rc.d stop dhcpcd
#rc.d stop networkmanager
Similarly, I put a ! in front of network in rc.conf:
# /etc/rc.conf - Main Configuration for Arch Linux
# LOCALIZATION
# LOCALE: available languages can be listed with the 'locale -a' command
# DAEMON_LOCALE: If set to 'yes', use $LOCALE as the locale during daemon

# HARDWARECLOCK: set to "", "UTC" or "localtime", any other value will result
# in the hardware clock being left untouched (useful for virtualization)
# Note: Using "localtime" is discouraged, using "" makes hwclock fall back

Restarting eth0 through wicd-cli still did not work. I also tried resuscitating the network via instructions on the configure network page before trying to focus solely on wicd.
I found a few similar problems on the forums by searching "wicd hibernate" and tried several solutions but they did not work. Several problems seem to be that the network doesn't work after a suspend because I guess the stuff in RAM did not get saved? But people were able to restart the network by running "/usr/lib/wicd/autoconnect.py" and I wasn't able to get this to work. As a final effort, I added "resume" into mkinitcpio.conf and placed the machine into sleep again to see if it may magically reset something but of course this did not happen .
mkinitcpio.conf:
# vim:set ft=sh
# MODULES
# The following modules are loaded before any boot hooks are
# run. Advanced users may wish to specify all system modules
# in this array. For instance:
# MODULES="piix ide_disk reiserfs"
MODULES=""
# BINARIES
# This setting includes any additional binaries a given user may
# wish into the CPIO image. This is run first, so it may be used to
# override the actual binaries used in a given hook.
# (Existing files are NOT overwritten if already added)
# BINARIES are dependency parsed, so you may safely ignore libraries
BINARIES=""
# FILES
# This setting is similar to BINARIES above, however, files are added
# as-is and are not parsed in any way. This is useful for config files.
# Some users may wish to include modprobe.conf for custom module options
# like so:
# FILES="/etc/modprobe.d/modprobe.conf"
FILES=""
# HOOKS
# This is the most important setting in this file. The HOOKS control the
# modules and scripts added to the image, and what happens at boot time.
# Order is important, and it is recommended that you do not change the
# order in which HOOKS are added. Run 'mkinitcpio -H <hook name>' for
# help on a given hook.
# 'base' is _required_ unless you know precisely what you are doing.
# 'udev' is _required_ in order to automatically load modules
# 'filesystems' is _required_ unless you specify your fs modules in MODULES
# Examples:
## This setup specifies all modules in the MODULES setting above.
## No raid, lvm2, or encrypted root is needed.
# HOOKS="base"
## This setup will autodetect all modules for your system and should
## work as a sane default
# HOOKS="base udev autodetect pata scsi sata filesystems"
## This is identical to the above, except the old ide subsystem is
## used for IDE devices instead of the new pata subsystem.
# HOOKS="base udev autodetect ide scsi sata filesystems"
## This setup will generate a 'full' image which supports most systems.
## No autodetection is done.
# HOOKS="base udev pata scsi sata usb filesystems"
## This setup assembles a pata mdadm array with an encrypted root FS.
## Note: See 'mkinitcpio -H mdadm' for more information on raid devices.
# HOOKS="base udev pata mdadm encrypt filesystems"
## This setup loads an lvm2 volume group on a usb device.
# HOOKS="base udev usb lvm2 filesystems"
HOOKS="base udev autodetect pata scsi sata resume filesystems usbinput"
# COMPRESSION
# Use this to compress the initramfs image. With kernels earlier than
# 2.6.30, only gzip is supported, which is also the default. Newer kernels
# support gzip, bzip2 and lzma. Kernels 2.6.38 and later support xz
# compression.
#COMPRESSION="gzip"

#COMPRESSION="lzma"
#COMPRESSION="xz"

Not sure if my fstab.conf is useful but if this has something to do with settings getting "lost" in swap, here it is. Linux is on an SSD and HDD (sda and sdc) and Windows 7 is on a HDD (sdb).
fstab.conf:

Is wicd causing these problems or did I configure something else improperly? Would appreciate any help to get eth0 up again!

Ok, I think I've made some progress! Hibernate definitely affects my network connection. Could this be a kernel 3.0 problem?
I noticed that ifconfig showed eth0 without an inet addr, just an inet6 addr for the longest time. e1000e seemed to be loading up ok. I'm not certain here, but I think that meant the dhcp settings didn't stick, or something along those lines.
Trying to use dhcpcd like the instructions here did not work. By some chance, one attempt did work and while it did, I downloaded and installed dhclient. After that one successful attempt, renewing the DHCP lease via dhcpcd did not work again.
Luckily though, I found that running "dhclient eth0" worked. My DHCP settings seemed to have somehow gotten messed up after my initial, problematic hibernate to the point where none would stick, even after a reboot. Manually typing in "dhclient eth0" would get eth0 working, so I decided to add it to the bottom of /etc/rc.local, like in the example on the networking page.
Now, eth0 works after a boot. However, after the daemons load up during the boot process, my computer takes a long time to get to the login prompt (this is relatively speaking, since I am on a SSD and the boot process used to be blazing fast before). I'm pretty sure it's because I added "dhclient eth0" to /etc/rc.local.
I should say that even with these changes, after a hibernate, my eth0 still does not work and if it weren't for the edit to /etc/rc.local, eth0's inet settings would still not stick after a reboot (that is to say, the hibernate does do something to my network settings).
Is this the correct/most efficient way to fix my DHCP problem? Can I fix my "eth0 after hibernate" issue? Also, can I make my DHCP settings boot up without changes to /etc/rc.local so that I can get a fast boot again (still not sure how it was able to work before without my edit)?

After update to OS X 10.7.5 on my Mac Pro (2009) USB ports don't work at all after wake up from sleep mode; with 10.7.4 there was (nearly) any problem.

hello,
after update to OS X 10.7.5 on my Mac Pro (2009) USB ports don't work at all after wake up from sleep mode; with 10.7.4 there was (nearly) any problem.
the used ports appear to be "killed"; the unused USB ports seem to work, but the Mac works in slow-motion.
The only "solution" is to restart my Mac.
- SMC-reset, PRAM-reset or repairing user rights had no positive effect; what is the solution - a bug-fix-update???

I have a mac mini (A1283) with OS 10.7.4. Upon upgrading to 10.7.5 it did not start up again. Instead, the light was on and the hard drive did not start up. The light on the connected USB mouse was not lit.
My solution:
Cold start with Command-v pressed.
This should start Verbose mode (see http://support.apple.com/kb/HT1492 ).
What happened on my mac mini was that the grey startup screen with the Apple logo appeared for a long while before the login screen came.
Maybe Cmd-v set open firmware params and fixed some corruption.
Anyway: my mac mini works again.

After update to 10.7.1, Wifi retrieved after wake up from sleep?

Anyone who had "no wifi after wake up from sleep @ MBA 2011 " issue before, is this fixed after 10.7.1 update installed? Any tester please drop your comment.

In another Mac forum saying that after the 10.7.1 update, need to reset the PRAM to get this issue solved.

9600M GT: 5W more power-draw after wake up from sleep?!

Hey Ladies!
I measured the wattage of my Macbook Pro with both the 9400M and 9600M and found that the 9600M GT draws 5W more power after wake up from sleep than before sending the MBP to sleep.
Looks like a bug to me?!

Application launches fail after wake up from sleep when switching from one open directory to another

I take my MacBook Pro back and forth from home to work. Open Directory is set up at both locations running on Snow Leopard server. These two locations are entirely separate domains and IP networks. The only thing that is the same is my username and password, which is the same in both locations.
If I put my machine to sleep in one location and move to the other location and wake it up, I can usually launch one application, then no other applications launch and the machine is pretty much frozen up except for mouse cursor movement. Using command-shift-escape and relaunching the finder doesn't help.
It is as if the launch daemon has been made inoperative. Apps just sit and bounce.
Should one be able to log in one one network with open directory. Close all applications, move to an entirely different network, and wake up from sleep and continue working? The login/password is identical on both open directory setups.
Both home and work are set up so the users can "travel" and the machines are not "bound" to the open directory server.
I've started using the "other" login box to login in which I think keeps the machine more independent of open directory and that seems to work better for moving between networks.
Any ideas and/or comment welcome.
(my DNS seems fine in both environments. running changeip gets "success" in both places)

After reading another post that popped up under "More Like This" after I posted this I may have found at least a temporary fix. Unplugging and reseating the MDP adapter in the MacPro didn't accomplish anything but unplugging/reseating the HDMI plug in the Viewsonic brought it back to life.
I guess I can live with this but it would be nice knowing that there's a more permanent fix for this.

Macbook Pro Freezes after wake up from sleep

My Macbook Pro 5,5 with mountian Lion freezes after waking up from sleep. i have 8 GB RAM and did a hardware test wich was passed. I also have a SSD of 240 GB in the optical drive. this is my startup drive. Another HD is my workdrive. The first thing I see is that the Airport does not come back and it seems that is does not wake up. After that the whole finder freezes.
What can be the problem?

Back up all data immediately as your boot drive may be failing.
If you have more than one user account, these instructions must be carried out as an administrator. I've tested them only with the Safari web browser. If you use another browser, they may not work as described.
Triple-click anywhere in the line below on this page to select it:
syslog -k Sender kernel -k Message CReq 'Channel t|GPU D|I/O|n Cause: -' | tail | open -ef
Copy the selected text to the Clipboard (command-C).
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window (command-V).
The command may take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear.
A TextEdit window will open with the output of the command. Normally the command will produce no output, and the window will be empty. If the TextEdit window (not the Terminal window) has anything in it, post it — the text, please, not a screenshot. The title of the TextEdit window doesn't matter, and you don't need to post that.

Output volume at maximum after wake-up from sleep

Hi,
I very often find my sound output volume at maximum level after my MacPro (10.6.2) wakes up from sleep. And I always have it set at about 20%. An unexpected 100% is overwhelming loud... I have no idea how to solve it. Anyone with a possible solution?
Mr. Pen

I use a little Preference Pane called Startup Sound which lets you set a default startup chime level. It hasn't been updated for ages, nor tested on 10.6, but it seems to work fine. You could give it a quick test to see if it helps.

Screen problem after wake up from sleep

About three weeks ago I posted a problem with the display coming back to life after waking up from sleep. I said this happened after the 10.5.2 update. This turned out to be not quite accurate. I actually ran all the waiting updates, so I really don't know which one to finger.
Today, I again ran the 10.5.2 update by itself. Everything is fine. Software Update then identified seven more updates to do, some familiar, some not. I have done all except one, one at a time, and have had no problems with the display coming on after the computer wakes up.
One more to go: Leopard Graphics Update. This is v1.0 for this update, and here is my question:
Before I run this update, and face another possible day-long re-install and re-update session, has anyone experienced the problem with the display remaining dark after running this update? I hate to do the update just to see if it causes the problem if there is some information kicking around about this.
Many thanks again for any help or comment.
Jim

Hi rohitgu,
Welcome to the Apple Support Communities!
I would suggest using the following article for troubleshooting the display flickering on your iMac. I would specifically Reset the system and Reset the resolution. I know you have done some good troubleshooting already. Have you reset the SMC as well as the PRAM? I also see that you checked the resolution on your computer, but have you started in Safe Mode and adjusted the resolution? Please use the following article as a reference.
Apple computers: Troubleshooting issues with video on internal or external displays
http://support.apple.com/kb/ht1573
Reset the system
You can reset the Mac's parameter RAM and SMC.
Reset the resolution
Start by resetting the Mac's parameter RAM. If the display does not come up, was previously set to an unsupported resolution, and still results in no video:
Start up in Safe Mode.
From the Apple () menu, choose System Preferences.
Choose Displays from the View menu to open the preferences pane.
Select any resolution and refresh rate that your display supports.
Restart your computer.
I hope this helps,
-Joe

LX195 WHS High hardware interrupts after wake up from sleep

I have a HP-LX195 windows home server which is set to sleep every day between 2AM and 7 AM. On wake up from sleep the CPU usage is triggered to 35-40%. No tasks are executing during this period and if any they add up the original usage. Using process explorer notices these CPU utilization is due to hardware interrupts. Using kernrate noticed the high usage is on intelppm.sys.
I have determined this is due to sleep. If the server is kept running without sleep, the hardware interrupt is minimal on normal operations. But if i manually set the server to sleep and wake up, the usage triggers back to 35 or 40. The high cpu utilization doesn't go away until restart.
I have tested this with other LX195 and it seems consistent and repeatable. I have posted this on microsoft WHS forum as well. This doesn't happen with EX490.
Is it possible to get a fix from HP regarding the same. Thanks Raja

does hp support monitor these forums?

How to take a photo after wake up from sleep

There are two questions:
how to create an automator to take a photo by isight in silent mode.
How to run this automator during the machine wake up from sleep.
Thanks a lot.

How do you make iAlertU take a photo and email it to you whenever the computer wakes up? I only know how to use it when you "arm" it as an alarm, which can get annoying to do all the time. I just looked in their preferences and I don't think you can set it to email you a photo whenever it wakes up without being in alarm mode.

Printing PDDoc with AFExecuteThisScript() doesn't work after an upgrade from SDK 5 to SDK8

Hello,
I have made an upgrade of my plug-in which was developed with the Acrobat 5 SDK. I upgrade it to Acrobat 8 SDK and my print function doesn't work anymore.
Actually I print my document using a javascript trusted function instead the function provided by the C++ library for internal reason.
Here below is the code used to print my document :
char szJavaPrint[6000];
sprintf(szJavaPrint,
"pp = this.getPrintParams(); \r\n"
// fill pp with parameters
"pp.interactive = pp.constants.interactionLevel.silent; \r\n"
"\r\n"
"this.trustedPrint(this, pp);"
PDDoc pdDoc = AVDocGetPDDoc(avDoc);
AFExecuteThisScript(pdDoc, szJavaPrint, NULL);
It was working with the Acrobat 5 SDK but the print seems to have no effect using the Acrobat 8 SDK. I know that there is a change between Acrobat 5 and 8 concerning the Character Set (currently I set the Character Set to "Not Set" in the Configuration Properties of the project) but I don't think that my problem comes from the Character Set.
All ideas to resolve this problem are welcome.
Kind regards,
Joe

See what happens if you remove the "setting of interactive to silent"...
There is a restriction on silent printing in Acrobat, but I would not have expected that to be passed into this method - but it could have been overlooked and be a bug.
Also, I don't recall a trustedPrint() method in Acrobat JS - check the documentation for the correct name of this function...
