Toshiba P840 Suicide

[JCIT]

I have a P840 that hard powered off while I was using it never to come on again (kinda). I was using an adapter from an Acer that is also 19v and am baffled as to how it happened.

While I had it apart, I was testing for shorts with all power removed, then once I put the battery back in (still no AC) it would power for a few seconds and then shut off, the only way I could then replicate that was to test all the battery pins for continuity (discharging??), after doing that I could put the battery back in and it would power for a few seconds and then shut off again.

Can anyone recognize the symptom?
I know I need to do more testing but I was hoping for a schematic or even service manual first, but I think its no hope at this time for such a recent model.

Re: Toshiba P840 Suicide

The power IC is an ISL95837HRZ, which the data sheets are still confidential.

I did some further diagnosis on the board today and it turns out some of the coils are shorted.

All this from saving a few bucks buying from auction.....
