My R40 doesnt respond. Problems a few days. Two short beeps and one longer then nothing a few days ago. I never did anything with the RAM <256Mb+128Mb>before. I now took them out, and put them back. It did start up, but soon froze in windows. I tried a few more times but eventually it went dead, no respons at all when pushing the power button. The following morning I swapped the memories in their slot position. The laptop started up...it kept freezing in windows from time to time. But has been working for about two days without problems. This time I moved the laptop a couple of feets from one table to another when it suddenly shut down. The power indicator and the angled "N", next to the battery sign is lit. Nothing happens when I press power button. I fiddled with the memory position of course. This time it didnt help.

Re: IBM R40 - 2897...not resonding
Disconnect any power remove battery .remove mem and check the mem slots for dust and debris replace mem.remove hd check connections(hd pins)check connecter for dust.refit ;make sure properly housed.reboot,enter bios.reset to default.save settings and exit.pc should now restart.any indications of fault maybe mentioned at startup if not window should boot

remove the power cord, remove the bios battery, short the two contact together in the battery holder for a few seconds, replace the battery and power cord and try again.
if that doesn't work, start removing items/plugs (not the big 20/24 pin one) from the motherboard until you get beeping noises.
if still nothing then put everything back and try a different power supply.
if that doesn't work, your motherboard is probably dead.
This could be a few different issues. Please state whether it is 2 short beeps, 1 long and 1 short, or 1 short and 1 long, all of these are different errors. If it is 2 short beeps you should see an error code on screen(usually 3-5 digits).
If you dont see an error code it is most likely and AMI Bios error and if it is 2 short beeps your IBM has memory problems. If you have no video at all on screen you have a parity error in your first 64K of memory. First check your RAM. Reseat them and reboot. If this doesn't do it, the memory chips may be bad. You can try switching the first and second banks memory chips. First banks are the memory banks that your CPU finds its first 64K of base memory in. You'll need to consult your manual to see which bank is first. If all your memory tests good, you probably need to buy another motherboard.
