Problem for Motherboards
Generic problem for all Motherboards
Acer 5920-6474 does not power on
When I plug my adapter (wall to adapter plug) green light on adapter is ON. When i connect the adapter wire to the laptop...the adapter light is FLASHING.. and NO POWER sign in the laptop...
no power at all in the laptop. Called ACER Tech and he said my ac adapter is broken or not working.
If anyone has / had same problem let me know...changing adapter solved or not.

- OK, i tried to power up with fully charged battery (charged battery on other acer laptop-as mine is dead) still NO power. I was running all time on AC adapter and NOT on battery so i guess the computer is set on the POWER MANAGEMENT SETTINGS of AC Adapter NOT battery so it wont start on battery (some one told me above-dont know if correct).
ACER Tech says mother board mostly is gone..needs replacement. or ac power jack connection with the mother board. He doesnt know why its not starting with the fully charged battery. Other acer tech send me new ac adapter -tried- same-NO POWER
Can anyone tell what might be the solution and approx cost..
thanks

the problem lies with failed smd capacitors grounding out underneath the motherboard on the same side of the board as the cpu heatsink. if you look at the board with the heatsink/fan in the top right hand corner- the culprit caps are in the bottom right hand region under some see through plastic. they are labeled pc144 and pc145.

Does your laptop power up on battery power? Have you removed all external devices (external monitor, keyboard, mouse, any USB device or expansion card, etc.)? Can you remove the CD/DVD drive? Do you feel comfortable removing the hard drive?
First remove everything you possibly can and see if the power adapter works. If it does, try adding and testing the items one by one to see which is causing the problem.
If the laptop will power up with battery and not with A/C adapter, it is very likely the adapter is the source of the problem.

- From what you told me, Acer tech is most likely correct. Laptop motherboards are not cheap and replacing them is best done by a professional.
There are a couple of options you might find attractive. Look on E-bay or Craig's list for someone selling the same make and model with a display problem. In other words, they have a dead or damaged LCD but the rest of the computer works well when attached to an external monitor. If you are lucky enough to find one at a very reasonable cost, you might be able to attach your LCD screen to the other laptop for a working computer. You could even swap out the hard drive with yours and everything should work getting you back to full functionality.
Another option is to go online or shop locally for a laptop repair shop. Get the rates up front and look for places that offer free diagnostics. They may be able to solder the joint on the A/C connector or even have a used motherboard replacement at a decent price.
A third option would be to put your laptop on E-bay or Craig's list and sell it as is and use the money with some of your own to buy a new laptop.
