R40 keyboard problem

I have an intermittent problem where the keyboard and navigator/ pointer freeze up. I use to think it was a memory problem but I have since found if I squeeze the base of the computer to the left of the inbuilt navigator pad everything comes good for a while.

Any ideas would be most appreciated

Re: R40 keyboard problem

The problem is the motherboard. From years of fatigue, the lower left portion of the motherboard develops small cracks, most likely from lifting the computer from this side. I had this same exact problem and after talking to Lenovo tech support, replaced the motherboard. Problem solved.

Re: R40 keyboard problem

Re-install the drivers.
Go to your "Device Manager" (Right click on ‘My Computer', select 'Properties', click the 'Hardware' tab, click the 'Device Manager' button. Click the "keyboard"). If there is some kind of a "Warning" icon superimposed on the 'keyboard' icon there is your problem!
Uninstall the DRIVERS for THAT DEVICE only.
Click on the faulty devise and hit the remove button, follow the instructions given by the program.
Shutdown, restart, the device will automatically reinstall by the "Found New Hardware" program.
Repeat for 'navigator/ pointer'.

IBM Thinkpad 2681 5UU freezes intermittently

When a system freezes it is typically the memory or video failing. It could also be overheating too. Try opening the unit and blowing out all the dust. Ensure the in and out air ports are clear too. If this does not help them you may have to have it services by a professional.

Bios battery location

On the R40, you will need to remove two things to get to the BIOS battery: 1) the regular battery, 2) the Keyboard. The BIOS battery is located just underneath the keyboard. In order to remove the keyboard you have to remove two screws from the bottom of the notebook (each will have a little picture of a keyboard and arrow next to it). Pop the keyboard up gently and the BIOS battery is just above the mouse buttons.

Check out the service manual for more details (pages 68, 77, 85).

Touch pad and keyboard freeze after startup

Check your memory. Reseat your memory. Try that first. The next step would be to get *********** board checked. All I own is Acers and I have had that same problem. Usually after reseating the memory everything seems to work just fine. But this could even be your graphics card. I would try and run a diagnostic on it and reseat the memory. You can run a diagnostics by shutting down the computer then hitting F8 and click on diagnosis and repair. And see what kind of a reading you get out of it.

sounds like there is a problem in the hard drive. Go to google and search for Hirens Boot CD it is about $10 but its well worth it. Boot from this CD and run the Check Disc Utility(chkdsk) and some of the virus tools, this might fix the problem, otherwise it sounds like a bad CPU or faulty RAM may be causing this broblem
