Lenovo U400 with Ubuntu 14.04 overheating with fan being idle

I've had Ubuntu 14.04 on my Lenovo U400 laptop for a year or so and everything was fine. Suddenly yesterday I noticed when I was working on it, that it was running really hot, almost burning my left palm. It's been quite hot in my area for a couple of days so this might have triggered the temperature, I thought.However what surprised me was that the fan was really slow. In the past it used to spin really fast whenever the computer was heating too much. I installed `lm-sensors` according to the Ubuntu manual. Here is the output of sensors-detect.This is the output at normal load: szymon@lenovo:~$ sensors

Adapter: PCI adapter
temp1: N/A (crit = +120.0°C, hyst = +90.0°C) Also when I boot up Intellij Idea and Tomcat (this was no problem previously, but the fan was spinning) these are the results and the fan is idle: szymon@lenovo:~$ sensors
acpitz-virtual-0
Adapter: Virtual device
temp1: +95.0°C (crit = +98.0°C)
temp2: +77.0°C (crit = +126.0°C)

Physical id 0: +96.0°C (high = +86.0°C, crit = +100.0°C)

Core 1: +95.0°C (high = +86.0°C, crit = +100.0°C)
radeon-pci-0100
Adapter: PCI adapter
temp1: N/A (crit = +120.0°C, hyst = +90.0°C)
This sounded quite alarming to me, so I tried to figure out how to control the fan manually to make it spin faster. I found no such option in BIOS. Then I installed `fancontrol` also according to the manual. Unfortunately, when running `sudo pwmconfig` I got the following error: /usr/sbin/pwmconfig: There are no pwm-capable sensor modules installed I tried fixing it with this hack, which consisted of adding `acpi_enforce_resources=lax` to the GRUB_CMDLINE_LINUX_DEFAULT. It didn't work, nothing changed when running `sudo pwmconfig` after updating grub and rebooting. I also tried to turn off the switchable AMD graphics following these instructions, but it didn't reduce the temperatures. Do you have any idea on why the fan isn't spinning faster at such temperatures or how to control it manually?

Did you get a kernel update recently?

Does anybody have problems with the Macbook Pro Retina 15' fans being really loud even when playing flash games like candy crush or tetris?

Hey guys,
So after a few months of using the MBP 15' Retina, I've discovered that the fans are incredibly loud even when playing flash games like candy crush or tetris.. are any of you guys having the same problem? Like all of a sudden from be quiet to unbelievably loud just as the games load. So yeah, hopefully someone has the same problem as I am having.
What I was thinking was that the MBP Retina 15' is such a beefed up laptop, it shouldn't require that much CPU to run flash games that are not even THAT graphically intensive to which making the fans that loud..
Thanks!

Believe it or not, Flash REALLY isn't the issue.
It's hardware makers making devices with less processor performance and requiring software makers to fit into a certain requirements of such. Namely iPhone, iPods and iPads.
Flash is designed to give a lot of features and work across many operating systems, browsers and platforms as a write once solution.
Flash has a certain level of processor performance requirement, which hardware makers like Apple want to build less powerful machines using less expensive processors.
Apple has removed Coverflow 3D effects from iTunes and discontinued the 17" MacBook Pro, leaving only the 15" as having a more powerful 3D capable graphics capability.
So Apple is obviously on a anti-heat/performance quest as they further thin up their hardware, trying to kill Flash by punishing Mac users who want to run it.
Flash runs without a fan sound on my older Mac with dedicated GPU and older OS X verison, no sweat.
Head to your System Preferences > Energy Saver and if you have it, uncheck Automatic Graphics switching, this will use the dedicated GPU and shorted battery life, but if your on power should reduce the heat and fan noise.
Another option is to use SMC fan control and set the fan default speed slightly faster, this will keep the machine slightly cooler and not trigger the higher fan speed as often.
If your running 10.8, you will need to System Preferences > Security > downloads to "Anywhere"
SMC FanControl is over at MacUpdate.com.

Dual boot with Ubuntu 13.0 using bootable USB problem (Y410P)

Hi I recently bought Lenovo Y410P and have been since trying for hours to dual boot with Ubuntu but I was unsuccessful.
I formatted by USB drive in FAT format, and created a bootable usb using Pendrive. Then I changed the Boot Mode to Legacy Support and the boot order so it boots from the flash storage first.
Then it hung on a purple screen like this: http://img829.imageshack.us/img829/3509/dgfdgrunningoraclevmvir.png
and the keyboard doesn't work and I couldn't go any further from here.
So I tried to use a different program called Unetbootin, and the problem got worse and it just stopped working at the option screen where you select whether to just try Ubuntu or install it, etc.
I read it somewhere the recent version of Unetbootin doesn't work, so I got the 474 version of it, and finally I was able to select from the option menu and it didn't hang. However when I clicked on Install Ubuntu, it just stopped there for a while, and then the boot failed and moved onto Windows 8 again.
I looked at the USB drive, and I realized the folder and some config files are names isolinux instead of syslinux, so I changed them, and now I'm getting the "SYSLINUX 3.86 2010..." words on the black screen and it hangs there.
I saw a similar message before using Pendrive and it was like "SYSLINUX 4.10 2012...". That was because the flash drive wasn't formatted in FAT (it was FAT32). So I re-checked the drive, but it is indeed formatted in FAT so I'm not sure why now I'm getting a similar message.
It will be much appreciated if you could give me some suggestions as to how to solve this problem.
Thanks

Something else you could try. Not sure it will make any difference.
Skip the boot creation tools and just boot the thing in UEFI mode.
Use the latest (12.10 or later will work, IIRC) 64-bit Ubuntu ISO. Format your flash drive as a single FAT32 partition. Extract the contents of the ISO to the flash drive. Use 7zip for Windows, or your favorite Linux de-archiving tool. That's it.
[edit] I don't believe the partition needs to be set active, but haven't tested that.
Set BIOS boot mode to UEFI. Even secure boot mode should work withe a new enough Ubuntu - but isn't necessary.
Give that a try. If it still barfs at the same place, mess around with the start-up graphics options.

Infinity won't work wirelessly with Ubuntu OS

I'm running Ubuntu Netbook Edition and upgraded my BT broadband to Infinity on 28.12.11, using the same HomeHub3 that worked perfectly well with the old Total service.
It doesn't work, wirelessly. I can get an apparently strong connection, but its agonisingly slow. At the same time, an ethernet connection works well, When I switch from one to the other and test the speed, I can watch the bandwidth fall away (i.e.: it isn't immediately disconnected.)
Nobody at BT can or will help, telling me that Ubuntu is 'unsupported' (i.e.: it's my problem). I reported this problem to BT - ref: xxxxxx-xxxxxx - via its complaints form on 28.12.11, but have had no response.
I've spent much time this past week on internet help forums. It transpies that BT has known about this issue with Ununtu for six months, but has apparently done nothing about it and cannot suggest a solution.
Suggested workarounds from other Ubuntu users involve manually reconfiguring one's connection, but my netbook won't allow me to apply the changed settings, or to change the router settings from N to G tech., but that only worked temporarily for me and, besides, my netbook is only a couple of year old.
When I was sold Infinity, nobody mentioned that it doesn't work with Ubuntu. Frankly, I feel it was mis-sold as I intended to increase the bandwidth of my Total account and was persuaded to take Infinity on the grounds that it's a superior service for the same price. Not from where I sit, it isn't.
The only solution I can see is to get BT to switch me back to their Total service, which suited me fine. I'm going to get their engineer to come back and uninstall Infinity. I will also complain to Offcom, as this situation could easily have been avoided had the BT sales person told me that Infinity won't work wirelessly with Ubuntu.

Firstly your negotiating skills with BT are far better than mine....
"....Total account and was persuaded to take Infinity on the grounds that it's a superior service for the same price"
I was on BT Total BB and had to pay an extra £2 pm for Infinity and then an extra £4.75pm uplift of the calls package to give me the same anytime calls I had previously.... And had to re-start another 18month contract!!! Ohhh well.
Right onto the problem... Webby's suggestion of making sure your on a clear or least used wireless channel is good advice.
Here is the link to the free software http://www.metageek.net/products/inssider/
Have a look at a demo,- http://www.youtube.com/watch?v=pf2kZCfYTxI
To be honest I would move your HH3 from the Automatic setting to a fixed wireless channel as they seem to work better like that.
If your Operating System won't work with Inssider I would then just try a different channel starting at 1 and work up... seeing how things go.
Regarding setting your HH3 to wireless g, that is a very backward step as the most you'll get over that would be around 20Mbps depending on your distance from hub etc.
Couple of pics comparing my speed test over wireless g and n in THIS POST.
Another thing I would try is a wireless n USB adapter... just in case your m/c is only g
Links of how to identify what yours is and pictures of the difference in the "Network Sharing Centre".. 54Mbps being g and anything above is wireless n....
Wireless n gives the best speed assuming your Infinity download IP is more than 20Mbps. Also wireless n signal is more robust penetrating walls etc.
There are links to the type of wireless n adapters I use... Picture of one HERE, (Don't need the extender cable shown in that picture).
wwwebber's post was very useful.-
"I use Ubuntu on my laptop with BT Infinity & HH3 with no problems at all. BT is not at fault here - they do not support Ubuntu."
Confirming Infinity and Unbunto do work...
You say ".....but my netbook won't allow me to apply the changed settings, or to change the router settings .... but that only worked temporarily for me......"
As changing settings worked temporarily you must have been able to log into your HH3.
If you really can't log in can you borrow a friends netbook running windows to get logged in perhaps?
Log in,- http://bthomehub.home/html/home/home.html go to Advanced settings, wireless. and change Channel settings from Automatic to a channel number then click on Apply.
I would place your laptop near to the HH3 and move the HH3 wireless channel to a clear channel or start at channel 1.
Try to get a good wireless n speed..... example of mine 37Mbps over http://www.speedtest.net/
Then when you have a reasonable speed move your laptop away... you will notice a drop over distance that's normal.
I am 20' away from my HH3 and get 37Mbps through a plasterboard wall.
Regarding other routers people have used http://community.bt.com/t5/BT-Infinity/List-of-Routers-to-replace-Home-Hub-3/td-p/298203
And see Ady's msg #21 and #25 in THIS THREAD.
"'ll try the netbook in different locations over the w/e and hope from a solution from Ubuntu before remonstrating further with BT".
Please let us know how you get on.

E1550 - unable to access USB drive with Ubuntu

I am probably overlooking something real obvious but after screwing around for two hours I figure I need some help.
I am running Ubuntu 14.04. I have set up the E1550 router with an external drive that I formatted with the router utility. At this point I do NOT have an internet connection hooked to the router - I am not sure I want to for now. What I would like to do is to be able to access, wirelessly, a drive that multiple users can use to back up their important files onto.
I have tried using anonymous disk read/write access as well as creating shares. All the features seem to be setting up ok but at this point I have no clue how to access the drive.
I have tried using the Ubuntu files utility and then selecting 'browse network' followed by selecting 'windows network'. Alas, 'windows network' is an empty file with no drive present.
I have tried accessing the router wirelessly and also hard wired - no joy.
Am I maybe not acessing the drive properly through Ubuntu? Do I need to mount the remote drive rather than accessing it through the windows network ?
Thanks in advance for any pointers given !
Solved!
Go to Solution.

I am not expert with Ubuntu OS but have you tried to map the drive on your computer? I have no idea how to do that using Ubuntu but if you're using Windows or Mac, you can simply follow the steps from Linksys KB. It usually helps me when I am trying to enable file-sharing capabilities within my network.

HT1604 i erased my hfs+ with ubuntu, how can I format it back to hfs+ please help

i erased my hfs+ with ubuntu, how can I format it back to hfs+ because ubuntu rejects the cd or usb formatted to mac os extended journaled and i am in a stalemate position. What can i do?

You're running Ubuntu, and that operating system generally doesn't utilize HFS+.
That you're then asking this question implies you were intending to not do that, or that you were intending to run multiple operating systems within one GPT-partitioned disk.
I'm going to guess you wanted multiple operating systems.
If you had intended to partition your disk and to use various file systems within the partitioning, then the command(s) that were used to partition or repartition your disk were not what was probably intended. (And this presumes that the two systems share compatible boot paths; that's possible with a system that can coexist within Apple's Boot Camp or Ubuntu or another operating system booted as a guest within one of the add-on OS X virtual machine products. I don't know for certain that Ubuntu can coexist.)
To get OS X back onto this same volume, you'll need to figure out if you have a GPT and then what's in your GPT, and whether there's a partition large enough for OS X to exist, or whether you can repartition your GPT disk to allow OS X to be reinstalled or reloaded into the partition. Or you'll need to wipe the whole disk, and replace its contents with a freshly-partitioned disk, and then load a copy of OS X that's been recovered from backup or freshly installed from distribution. Or you'll need to provide another disk, and then partition and load an operating system (either Ubuntu or OS X) onto that as appropriate.
The tools for doing the repartitioning within Ubuntu are best discussed with folks more familiar with that operating system; I'm not sufficiently conversant to suggest tools for that. I'd suggest a forum specific to Ubuntu for that. The tools used to repartition the disks on OS X generally involve the Disk Utility tool, whether booted from DVD (Snow Leopard), from the USB key disk (Lion), from an external OS X disk, or potentially using Target Disk Mode from another OS X system. And the OS X tools for repartitioning are destructive; they generally don't save what's in the existing partitions, if you need to make an existing partition smaller.
The usual sequence (and the one that's easiest to describe) to establish the environment starts by wiping the whole disk, and establishing GPT partitions of the appropirate sizes using Disk Utility or its Ubuntu GPT-aware analog, and then loading the target operating systems into each. Alternatively, you can read the Boot Campe documentation, or review the documentation with the particular virtual machine product that you're going to choose and use on OS X for details of how to manage its guest operating systems.
Without some idea of your end-goal here (and where you're stuck in the current environment), it's hard to provide more specific suggestions.

Re: BIOS version 3.30 Tecra A11/M11: Problems with Ubuntu systems?

I just got the invitation to update to BIOS version 3.30 on my Tecra A11/M11.
I'm still running Win7 right now but plan to add a dual boot with Ubuntu when the next LTS hits in April.
Is anyone having trouble with the new BIOS?
Should I upgrade, or leave 3.20 intact?
I find no evidence of trouble with 3.20.

Why to upgrade the BIOS if everything is OK?
Furthermore as far as I know Toshiba does not support the Linux OS and I doubt the new BIOS would improve any Linux performance so if you are happy with the v3.20, stay with that

Lenovo S205 & Windows 7 64bit. Problems with graphics, please help

Hi,
I recently bought a Lenovo s205:
AMD E-350
It came with 1GB but I upgraded it to 4Gb RAM (1333 running at 1066)
Windows 7 64 Ultimate.
I have tried also Windows 7 32 (Professional, ultimate) and all versions give me the same problem, I will explain here:
I have tried in AHCI mode and IDE mode from the bios and done fresh installs of Windows. Still the same.
After installing all the drivers, I get randomly in different programs "black" or sometimes "white" menus. Whenever I set the cursor on the menu (White or black part), the letters start showing up.
On Firefox for example, it happened where you write the address (Ex: www..) And when searching images too.
I have tried the original drivers that the Lenovo's website has for the S205 and the latest from Ati/AMD and nothing solves the problem.
What can this be? Faulty ram? Faulty OS? Problem with the graphic card drivers?
Please help, it is so frustrating.
Thank you so much.

Thank you very much for your help.
I will try capturing some screenshots if that helps.
I can discard the problem with the ram at the moment. I have tried a new set of ram (two 2gb modules = 4gb in total). The problem persists, even when they are tried individually. I also tried the original ram module the Lenovo came with (1module of 1gb), alone. Problem persists too.
However, I do not have a problem trying the VGA output. Will this help too? As I do not have any screen with HDMI at the moment.
What I will do too, is to try a Windows 7 from another disc, a Home version 32 bit. I hope this can get the problem fixed.
The main issue is that I bought this computer from Germany (From a store on eBay) and came with DOS. I will have to return it to the seller, I assume, if the rest fails to show any improvements.
Thank you for your reply and any more suggestions are welcome.

Attention! Laptop Lenovo IdeaPad Flex 10 is not compatible with Windows 8.1

Attention!
Laptop Lenovo IdeaPad Flex 10 is not compatible with Windows 8.1 and Windows 8.1 Update (pre-installed operating system is Windows 8.0) .
More specifically, after update for Windows 8.1 all the drivers (including the latest) Intel (R) Iris (TM) graphics, Intel (R) Iris (TM) Pro graphics and Intel (R) HD GRAPHICS installed on this laptop does not support out of the sleep mode.
This has been checked many times by different users laptop Flex 10.
Any comments from Lenovo are absent. By Lenovo specifications for this notebook there are no conflicts with Windows 8.1. It is not true!
It is unclear why Lenovo has admitted this deficiency.
I think Lenovo Flex 10 is a mistake that will cost the company Lenovo.

Mine came with Windows 8.1

Firefox 7 does Win XP into a blue screen, when I use FF7 with Ubuntu on the same pc the pc does not crash. So it seems to be a problem of win XP and not my pc ....

FF 7 opens and then after a few minutes the pc goes to a blue screen.
the blue screen advices a bios upgrade, but with Ubuntu (most recent version) I can use FF endlessly without any problem.

Instead GarageBand recognize my keyboard and i can play normally, also, if it can help, those are the Audio and Midi Logic Preferences and the Controller Surfaces Setup with the keyboard connected :

You probably need to learn more about partitioning and partition types. Read everything relevant here:
http://www.dedoimedo.com/computers/gparted.html
Pay close attention to partition types and extended partitions. You likely need to use an extended partition.
(Not sure why 40 people looked at this before me and nobody bothered to tell you the easy and obvious suggestion...nice.)

Are you trying to update the original Xcode installer, is it still resident in your Applications folder? Because that is usually why a delta update is involved, it is updating a previous version of an app. If this is the case, then I would put the installer in the Trash and restart the Mac. Do not empty the Trash. Now see if the MAS will allow you to download the full installer for Xcode, since it can no longer detect the existence of the previous versions installer.

MIcrophone on HP mini 1000 not working with Ubuntu

I have an HP mini 1000 with Ubuntu installed on it. I have tried to use the microphone, but it doesn't work... I don't know if it just because I don't have the right drivers, or that it is broken.... So I am wondering where I could find the right drivers (Or if there is a fix), or wether I should just send it in to get fixed.
Thanks.
P.S.- If you need any more information about this, just tell me.
This question was solved.

HP is setting up a URL now. Once I have that I'll post. It should fix most of your problems since all the Ubuntu drivers have been testeda nd qualified on the MIE image (including the mic). I was told it should be a day or two.
