CF-Y4 Repair-- No power. (Repair manual? Tips?)
Posted: Thu Dec 17, 2009 10:14 am
Hello fellow toughbook enthusiasts,
I'm quite depressed to report that my Toughbook Y4 no longer accepts power from its brick. Nor from the replacement brick
I acquired last time this happened. It was sad to be using it, plugged into the wall, watching the battery slowly drain, knowing
that there would be no coming back from 0%.
This is the third time I've seen this problem; the first time, it started working after a little bit of time. The second time, I
bought a new power brick, and by the time it arrived in the mail, the laptop was working again. I'm not sure if I'm burning through power bricks or not, but I suspect a problem with the voltage regulation/socket on the motherboard. Maybe I'll be lucky and the socket is no longer soldered well, or there's an obviously bad solder joint that I can fix.
In any case, I come here seeking advice and mayhaps a Service Manual, before I pull out the multimeter and open this old friend up.
Thanks,
-TJ
