Question about IBM ThinkPad R40 2897 Notebook

IBM R40 - 2897...not resonding

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.

    Thx for the advice, unfortunately it didnt help. I replaced the memories and check for dust. could it be something else?

    Small hints -

    When pushing power button all led lights lit up. but to stop soon. Z and battery led stays lit. Battery led blinks every two seconds when power cord on, stops blinking when cord off. Z led lit green when power put on. indicating PC ready for use. Holding power button down for about 10 sec makes Z led lit turn off. No change when HD out. CD drive doesnt respond. Thats all thats happening...no beeps. I suspect something burned? Diagnostic next?

    I'm having the same problem with my IBM thinkpad R40.  it worked one day the next it started up but went to a page where I was givien some choices of how to start it up.  one was in safe mode.  I cant remember the other 2 and the last one was to restart in the last successful mode.  which was windows. The screen also had a count down clock of 30 sec. then it would automatically start in the mode that was highlighted, or enter the one you choose.


    IF i got the above screen it would try and start xp but then would go to a blue screen with white writing that wouldn't stay up long enough to read it. and sometime it would return to the above described screen or it would shut down and give me the batt light and the Z green light.


    I pulled the battery out overnight and tried to start it today.  I got either 3 reps of 4 beeps each the same length in sound..OR maybe it was 4 reps of 4 beeps each with the same length in sound.  Lost track of reps.


    I took the hard drive into a store and they checked it in the back room and said it started up fine.  I only have one stick or ram and swaped ports a couple of time and nothing changed.


    SO...I'll be watching you post to see if there is something to be said

    While working on my laptop all kinds of windows suddenly open without me prompting. I can't get rid of them. I have to restart every time this happens, several times a day.

    make sure everthing is connected up.make sure you have os in cd drive.startup.system should detect cd and say press any key to boot from cd .if so press any key.if not soft boot to restart and enter bios and select cd for first boot in boot options.save and exit.pc should now start with boot from cd option.

    let the disk boot.on screen ask install windows or repair ,choose install.system will check devices.if hd is damaged this is where youll find out,though still possible to reformat and install new os ,if you get this far and need more info let me know.

Lg ibm multinet i tower allows power to the motherboard but wont start up, what should i do?


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.

Quite awhile ago, one side of the unit went dead. Uesterday, after hearing a couple clicks, the unit will beep a few short beeps, then after a little bit, there will be a few short beeps again. I press the...


sounds like it is failing. When was the last time you tested its capacity? Test it to see how long the battery works. If it doesnt then get a new one or send it back where you got it.

2 beeps then error


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.
