Re: Acer aspire 5742z no power / dead

Did you eliminate the obvious:
1. test power supply for stable 19V output
2. make sure you have 19 input at the connector (plug it in the MB and test the solders that are on the motherboard)

Capacitor PC343 (far right, big electrolyte one) looks bulged on the pic. Perhaps it's shortened?
Just a thought.

Re: Toshiba Satellite c650 no power to battery and no motherboard lights

OK, I dont have experience with the C650, but just a few remarks about your testing. Remember that capacitors don't conduct DC, so many times you'll find a 19V readout on one pin, and 0V on the other pin of the capacitor. That's how it should work. Usually their job is to just filter out any current noise.
The capacitor does seem damaged, but I doubt a single capacitor would kill the laptop, knowing they're mostly current filters. Definitely replace the capacitor is a first step, and if nothing happens,...

Re: toshiba satellite m60-104



The maxim reflow that marcellodj mentioned is unfrortunately a rather common problem. A few years ago I had a Toshiba m35 that behaved in very much the same way. It took me an entire year to figure it out, and burnt one MB that I got off ebay, but eventually I got things right. A good reflow will do the trick just fine.
It will be easier for you to find a how-to guide if you google "toshiba m35 maxim chip repair". It's really not that difficult, and it shouldn't take more than an hour to take the laptop apart, do the...
