CPx died 646

Interesting development. Originally whilst in the process of flashing the BIOS the battery died and the laptop did not power up or respond at all.

Dead, I thought, so it doesn't matter what I do with it. I decided to take laptop apart to see of there was some kind of reset jumper on the mobo somewhere, in the manner of the Factory Reset option in Nokia mobiles. Reduced laptop to component parts, no jumper found. Ah well, I thought.

Rebuttembled laptop with no leftover parts, plugged it into the mains and pressed the power button just for curiosity's sake and lo!, it sprang to life and now works fine. Interestingly the BIOS is the same version as it was before this debacle began.

Now after I'd end it first time around it didn't work under mains power, or with the battery. It now works with both. As the BIOS seems to be untouched perhaps the psu is on it's way out and that's what caused the problem. In any event I'm not complaining.

Thanks for all replies.
