I know this is a bit of a long shot, but please bear with me. My Fujitsu Siemens S7010 notebook no longer powers up.

Presently, when I plug in the AC adapter, an AC icon briefly appears in the LED display, then disappears after about 1 second. The same goes for plugging in the battery: a full battery indicator lights up for 1 second, then everything is dead again. No display, no fan; pressing the power button has absolutely zero effect, except if I immediately hit the power button after the indicator disappears. In this case, the AC indicator lights up for a fraction of a second, only to disappear for good.

The machine has been having increasing difficulties getting started over the past week or so. I backed everything up because I was worried the PSU was giving out, and sure enough, that day has arrived. After disassembling it, however, I couldn't find any broken solder joints or burnt out capacitors.

I've tried removing and reinserting the HDD and DDR banks; no dice. Also detatching all devices has no effect.

Is there any hope for this machine?

After some more investigation, I have considered it totaled as I suspect that the PSU is burnt out. Unfortunately, the PSU is embedded into the main board, so the cost of replacing it would exceed the value of the machine.

Sounds like you're probably right that the PSU has given out, and laptop mainboards are rarely worth replacing. –  jcrawfordor Mar 25 '11 at 0:26
