Question about IBM ThinkPad T40 Notebook

1 Answer

Freezing I have had two of these machines which have both developed the same problem.  After a while of using it, it completely freezes, won't move, turn off or nothing.  I have since tracked to it when ever the machine is moved, no matter how slightly. Is there a quick-fix or a fix at all or should I be looking at a new machine. I have been previously advised that it is something to do with the power supply but a second opinion and advice on how to repair it wouldn't go a miss. Many thanks. Jonny

Re: Freezing

I have seen this on the T40 series when the video chip on the motherboards fail. the only fix is a new motherboard (usually about $150-$200 plus labor.

You may want to check if they are under warranty - a lot of these had 3 years on them and may still be covered. just google "ibm warranty lookup" and there should be a link to IBMs site for warranty info. They will honor warranty even if you are not the original owner.

Good luck!

Ibm a 31 freezing

follow this steps and fix it. God bless you

If the freeze happens every time a certain hardware device is plugged in or switched on, the device itself might be to blame. Check the manufacturer's website for updated drivers for the device, and download and install them to erase any bugs that might exist in your version. Similarly, if the freeze only happens when using one particular application, that program might also be the root cause. Check the developer's website for updates. If the problem persists, uninstall and reinstall the program. This process replaces any software files or settings that may have been damaged or deleted.

Hello xqiqqlesx715,
If your computer is brand new like you nention, I strongly suggest that you go back to the store and ask them to fix it, It could be a defective component, if you wait too long, you might have to pay to have it fix, !

I have the same "freezing" problem!

the freezing issue could stem from these problems:

corrpupt/bad software on HardDrive for operating system

bad drivers for the unit

motherboard overheating

lets start off with a few things. first tap f8 select safe mode. see if you get the freezing up issue then.
if you dont, then its a driver related issue:

for driver related issues, go to and download any available updates to your software (bluetooth,wireless,video card, and so on) including the bios flash update. you will more than likely have to get these updates by booting into f8 selecting safemode with networking to get access to the internet.

If the machine freezes up still , then its either a corrupt O.S./bad hard drive or overheating issue with motherboard.

to determine the issue reboot the machine after it freezes, go f8 for safe mode boot w/networking and do this:

go to and download all the updates for the driver software and bios (bios is very important) there have been some updates to these areas for issue related to motherboard problems. after you install all the updates select to not Restart computer yet (which it will ask after video driver updates and so on) now go to my computer, right click it, select properties and in the tools tab select the disk check option. from there check both boxes and then restart machine.

what this will do is check the disk for errors and bad clusters, and load the correct new/updated drivers, when its done it will restart and by then have moved bad areas to new places. if it freezes up during this process the drive may have hit a snag and you need to replace the hard drive.

if you continue to get this problem after all this, i suggest seeking professional assistance for motherboard overheating issues. i have fixed those problems by applying new thermal paste to the heatsink fan assembly and adding it to the GPU chip also. but in some cases i had to reball/reflow the GPU chip, which runs 80-140 depending on where you go. ebay has a few good vendors that do this.

Good Luck! I know its alot, but that should eliminate the majority of issues

Keeps freezing

starting the machine without a power cable isnt bad, especially since its a laptop and is made to run on battery power. as for the freezing, if it was dropped alot then something could have come loose meaning it mite not be covered under warrenty. i would just try to get it fixed at the place it was purchased at.

Laptop freezing up

Could be several things such as Bad Ram, Bad program/bug running in the background, Processor overheating. or as bad as a/Bad Motherboard. If warranty, then call Toshiba otherwise here are some solutions to experiment with. 1) If bad ram - try swapping with a friend who has similar type of ram 2) Reload or Debug widows 3) Blow out vents, especially around heat sink and fans 4) Have a service shop verify then if bad motherboard and shop online for cheap used motherboard. Keep Me posted. - Scotty
