Oh bloody power!

Bleh, sorry to keep bringing my laptop woes to the board (though I'm trying not to err by necroing), but I had a guy take a look at it to see just where the problem -- my laptop at random goes off as if depowered, then while random usually won't turn back on for a while, and I sometimes hear a squeaking noise when the lights flash [before going out again] -- might be (since I did believe that it was the hard drive), for which he unscrewed a lid and reseated the outermost RAM chip, causing him to figure that it was loose RAM, maybe from the aftermath of a physical shock (I once dropped my laptop corner-first on my toe by accident), and it did stay on and stable for the next six hours afterwards... only to out of nowhere go off again. :roll:

Moreover, having done some more testing today, the "charging" LED now blinks slowly instead of staying on constantly or being off when the battery's fully charged, and while I found that the battery was 92% this morning (), but when the LED blinks, Windows' power meter shows that it's on AC power and the battery being 0%... :shock:

P.S. There's no apparent problems with the hard drive, other than one time that CHKDSK ran on a successful boot and partly messed up my Firefox bookmarks (I'd be editting the list at the time of one of the random "go offs".)

What kind of laptop is it?
A lot of MacBooks had random shutdown problems, Apple eventually figured out the problem:
"Essentially the heatsink can expand during use, and comes into contact with the lead from the [thermometer's] sensor cable," reads a more detailed explanation posted at Ogrady's Power Page. "A short circuit results, and the SMC (System Management Controller) pulls the plug. Once the system cools down, the heatsink [recedes] and the contact is broken."
and released a firmware update to improve the internal monitoring system to prevent that. It could be something like that...

I don't know if that (is even possibly) the case on a non-Mac, but I have a HP dv1000 series that's at least a year old, possibly/probably two. Don't think that I can afford to "just" scrap it, as I intend to hand it down eventually.

P.S. That article or problem ever include the "inability to power up and LIKE IT" problem that I described in my OP?
