Thinkpad T23 Freezing

Ibm / Thinkpad t23

Specs: Windows XP
I have this old Thinkpad T23 that I am working on. It is a Pentium 3 M 1.13GHZ with two 256MB RAM sticks in it. Sometimes it will randomly freeze with no error message. When I manually power it off then back on, it just beeps with nothing on the screen. The only way I can get it to come back on properly is to pull the ram and re-seat it. After that, it will boot up and work fine for a while, then it just happens again. I tried different RAM sticks with no luck. This laptop has a new battery and 80GB hard drive, if that helps. I know this laptop is way out of warranty. Any suggestions?

run this

I have the same laptop, could try creating a cd of this and running it
If I remember correctly, puppy picked up all the hardware on that laptop, including the wireless. Boot from the cd and, it will load & run from the ram. If it runs without problems, this may indicate hardware is not the problem.

Yes, Puppy sees all the hardware on a T23. MemTest should be run as suggested and any ram (if any) that fails needs to be removed. Puppy Linux runs well on a T23 and will eliminate any problems with XP you might have.

Some ?'s...

You still have the original 30Gb hdd in your T23?

Does the cooling fan come on three or four times an hour?

Thanks for the responses.

I have replaced the hard drive in it with a new 80GB 7200RPM, since the original drive crapped out. It does not have built in wifi, but a PCMCIA wifi card. This problem occurred before the hard drive was replaced, and continued afterwords.

I ran some memory and CPU tests using Ultimate Boot CD, and they all came back fine on the first iterations of each test.

The cooling fan comes on a few time an hour. When it does come on, the air blowing out will be extremely hot, and that's even sitting on a flat surface with plenty of ventilation.

I read somewhere that some of the Thinkpad laptops had faulty motherboards that failed when both memory slots were used, but the T23 was not on that list.

I will try to use the Puppy Linux and see if it finds anything.

OK. Those original hdd's were a problem on many T23 machines and your cooling fan is working like all the others I've seen.

I'm not aware of any particular T23 motherboard issues; mine works fine with 2 x 128Mb SODIMM's.

Let us know if Puppy makes a difference.

MEMTest86+ passed with no errors and Puppy loaded fine. I still think it may be a hardware problem since I have to pull the RAM and re-seat it each time it freezes in order for it to boot up again. Otherwise, it will just sit there and beep.

Any other suggestions?
