T20 System Board failures?

[Oraklini]

Refurbed a T20 using a new system board about three months ago. All was sweet. Sold it on, got a call around a month later, the system would not start (bod symptoms)

Fitted another new board, all ok until today(a month later) then a call with the same non start. I've got another board to fit but it's the almost identical failure/timespan thats odd.

The other three T20's refurbed with new system boards at the same time are all ok to date.

Collecting the offending TP tomorrow, suppose there could have been a batch of faulty boards?

Any thoughts...

You've got a PM.

It's not unknown for buyers of laptop bits to exchange perfectly good bits they've bought from us with faulty items, and to then claim they've been sold a faulty part.

To prevent this fraud, every item we sell is tagged in a particular way (sorry but I'm not saying how).
If there is a return we immediately check to make sure it's been returned with the same bits it was sent out with.

We recently won an Ebay claim where someone tried this on, and was subsequently banned for fraudulent practice.

I'm glad to say that it's extremely uncommon but unfortunately it happens and makes you wonder why you bother to try and offer a dencent service to people.

I can't offer any practical answers to why your boards are going wrong.

Hope you can get it sorted OK.

Good idea, to 'mark' those replaced parts.
With mobos you could register the mobo serial number.

As to cause of failure, it could be the I/O board at the back that is flaky. I've had a T23 with similar (I/O) failures.

Thanks for the replies. I sell my Thinkpads to students at the local uni,
you wouldn't think for a minute the young lass who bought it would rip it apart and change the mobo

It is strange though, as what I did on the initial repair was to swap the screen/lid and upper plastics onto a refurbished base(with new mobo). What wasn't changed was the power supply.

I'll do another repair and mark the parts and wait and see what occurs.

Cheers
