T22 turns itself off

Hello,

I have a T22, which has worked perfectly for the past year. All of a sudden, a few weeks ago, it turned itself off and would not go back on. I checked the power leads and all was well with them. So I left the laptop off for a few hours, came back to it and it fired up just fine.

For a few days everything was ok, then the same happened again (and again and again.........)

I put it down to limping along with windows 98, so upgraded to Windows 2000. I came in yesterday morning to find the exact same problem. This morning I had the same again. It won't fire up if I try to switch it back on immediately, but after a hour or so 'rest' I can use it again. It might then last for an hour, or for another 16 hours - there appears to be no pattern (no warning before it goes off either)

It's an intermittent problem. I have the latest BIOS software update. The battery doesn't hold much charge anymore, but I always work with it plugged into the mains anyway, so I wouldn't have thought that would be causing a problem.

Any suggestions?

Kind regards
Rae

Did you power up with the weak battery installed? If it is I suspect, it is the weak battery that is causing it. I suggest remove the battery, and operate using the main. I think the problem will disappear. Otherwise change to a new battery, it is quite cheap nowadays, just bought a reconditioned one, about US$40 incl. postage.

I know eBay has tons of batteries for the T22, but avoid the non-OEM. If you can, go for the battery that has IBM logo on it. Also, use the diagnostic diskettes to see if there is any else that may be wrong, to be on the safe side.

Thank you both for taking the time to reply. I'll remove the battery and see what happens (it would appear batteries are rather more expensive over here, but thanks for the tip on which one to look out for; I appreciate it).

Since installing Windows 2000, the 'thinkpad' key at the top left of the keyboard doesn't do anything and I didn't get any diskettes with the machines, so is there any other way to run these diagnostic tests?

Many thanks again
Rae

You can always download the Software Installer from this link, since you are now using Windows 2000:

http://www-307.ibm.com/pc/support/site. ... AIBM-INDEX

This will help you download a lot of original IBM Thinkpad features that came with your Thinkpad, and then some....including fixing your THinkpad button.

Well, a little update from me:

I removed the battery - no difference.
Cleaned everything up a bit - no difference (and to be honest, not a lot of dust either

).
Ran the diagnostics - no problems there and now the machine is only staying on for about 20 minutes - yikes!

Do you sense this is hardware or software problem and where would you suggest I went from here?

Kind regards
Rae

Have you noticed any heat issues? Does the fan appear to be running?

It sounds like it might be overheating and then shutting off to avoid damage. Continued overheating will lead to replacing the system board.

Looks like it is not the battery causing the problem. You can try this to isolate whther it is hardware or software problem.

Get a CD where you can boot it from, eg. DOS CD or any Test CD, boot and leave it for a period of time and test any hardware you like and see whether it switches off. If it occurs then, it is definitely hardware is causing it, otherwise the windows 2000 or the harddisk which may be causing the problem.

Try it hope this helps.

Wow - you're all so helpful and paitent with my questions - thank you.

tfflivemb2, I haven't noticed any heat issues - I'm aware that the T22 has a reputation for getting a 'little hot under the collar' but tbh, have not noticed that - could it be that the machine *thinks* it is getting hot; does it have a thermostat or something that could be faulty??
The fan appears to be cutting in ok as usual (but of course, probably wouldn't need to if it only stays on for 20 minutes!)

ttan98 - thanks for your suggestion; I'll try that out over the weekend

Thanks again folks. Enjoy your weekends
Rae

Hello!
I think that the heat is quite possible reason for this behaviour. I suggest you to observe this: http://www.pbus-167.com/chc.htm. Download the program and see what is your shut down temperature and the current level. Something interesting: I own ThinkPadR50p, when I instaled this program, the temerature on stand by(nothing is started) was 60C. When I removed keyboard and cleaned fan and air-path with compressed air (holly molly, how much dust was blown away), the temperature (in the same condition) drops to 40C. This amazed me. So chek this out and post the results.
Good luck
Did

Hi Again,

Right, I have come to the conclusion that it *is* a heat issue - I've realised that the fan is not cutting in at all, and when the computer turns off after 10 or 20 mins, those are the times when it is on my lap and I am sitting infront of the fire

At the times it stays on longer, I am in the other room, which basically has ice on the inside of the windows!

So, I will run this test you talk of, Did and post up later. Wish me luck!

Enjoy your Sunday, everyone
Rae

I've installed the recommended software but would like to ask if anyone knows at what temperature the fan *should* cut in please?
It went up to 56 degrees yesterday, but then I turned it off rather than running it until it switched itself off.....

Many thanks
Rae

you s/w you use to monitor temp?

looks like you may have to open up the casing to clean the fan, and maybe also the heatsink contact with the CPU. remember to apply thermal paste....

Hi.
My R50p turns fan on ,when power up (first slow then fast) and turns off. When windows starts temperature is 40C, after some graphical jobs temp rises and when reaches 65C fan turns on (slow speed) if I stop to work and temp decrease qiuck below 60 fan turns off. But if I continie fan is on regardless that the temp is 44C. Obviously, the fan's operation is controled by some algorythm dependig by many factors. Hope beeing helpful.
