Re: Laptop no power

My old Toshiba has done that a few times. In my case I know why. When I dismantled it I weakened the power ribbon cable connector under the keyboard. Pushed in well with a bit of sticky tape across it, it's fine now.
I would guess the power ribbon has slipped out a bit on yours?
On the Toshiba when the big power button wasn't working there was a couple of small "help" buttons underneath that continued to work booting to a Toshiba windows help page,
Any extra similar buttons on yours?

Re: Laptop no power

Tried pressing the power on button & then F2 (or whatever it is to access the BIOS), if that appears, then try doing a reset of the BIOS and reboot and it might well work properly again.
I had an ASUS that did it, then I did a BIOS reset and all was well & good until the display went kaput.

Re: Laptop no power

At a guess, it's either the connector that goes to the motherboard that has worked loose (as already mentioned), or the motherboard has a flaw that would probably render it completely dead and requiring replacement, and from my experince of laptop repair, acers are great at randomly dying for no reason... Undecided
Hopefully it's something simple that can be sorted with a bit of screwdriver spinning, often the most annoying problems are the easiest repairs...

Re: Laptop no power

If the laptop won't power up with battery out and mains adapter plugged in then you either have a duff mains adapter or more likely a faulty power converter board inside the laptop.
Could be something as simple as the power jack on the main board has come loose (quite common) but often slightly more "terminal"

Re: Laptop no power

Whip out the hard drive (data protection and all) and stick the laptop on ebay, someone else will enjoy having something to fix up I'm sure... Grin
Even I don't attempt soldering on that small a scale... Shocked
