|....well...I have a nc6000 HP craptop here that only powers on if I press hard on the deck of the laptop while powering it on (Maxim 1987 chip issue). |
There are all sorts of small micro fissure circuitry issues with motherboards, especially with HP laptops lately it seems (per the first link in response #1). Sometimes REFLOWING works to solve these issues, but that requires pulling the motherboard, reflowing the bad components or doing other component level repair on the motherboard, putting it back in the chassis and testing it (hopefully thoroughly).
If it doesn't work ALL the time EVERY time and if the circuits do not stay open & energized ALL the time, what good is it? Ah yes...a paperweight...?
Just another stupid saying...
