Acer Aspire won't power up

I have an Acer aspire 3680 laptop. It will not turn on when i press the on button - even when connected to power. It has just stopped working all of a sudden with no warning. Does anybody have any ideas what it could be and how i could go about fixing it? Thanks :)

Power related errors on notebooks usually require the replacement of the mainboard. If it's not under warranty that usually costs around $1K, if not more. Unless you get lucky and find a replacement mainboard on ebay from the US, and you might get it for only $150 or so and you can install it yourself.

Otherwise I suggest you contact an Authorized Acer repair agent (who will most likely charge you to tell you the same thing :P).

or it could be the power connector believe it or not. Does the light turn on to tell you that its charging when plugged into the power?

Yeah the lights come on when its connected to power, battery is full. Now that i think back, last time i was using it, it just turned off all of a sudden. IT made a click sound when it turned off. I put it down to a flat battery but now i remember it was connected to 240v.
So i guess main board sounds like a good bet as sexkitten said, unless anyone else has another idea?

Unplug the mains power and remove the battery pack. Wait 10 minutes and plug back in.
Just in case an internal circuit breaker tripped that needs resetting (the click sound).

Taken from the Aspire guide:

Power System Check
To verify the symptom of the problem, power on the computer using each of the following power sources:
1. Remove the battery pack.
2. Connect the power adapter and check that power is supplied.
3. Disconnect the power adapter and install the charged battery pack; then check that power is supplied by
the battery pack.

If you suspect a power problem, see the appropriate power supply check in the following list:
“Check the Power Adapter”
“Check the Battery Pack”

Check the Power Adapter
Unplug the power adapter cable from the computer and measure the output voltage at the plug of the power
adapter cable. See the following figure
1. If the voltage is not correct, replace the power adapter.
2. If the voltage is within the range, do the following:
* Replace the System board.
* If the voltage is not correct, go to the next step.
NOTE: An audible noise from the power adapter does not always indicate a defect.
3. If the power-on indicator does not light up, check the power cord of the power adapter for correct
continuity and installation.
4. If the operational charge does not work, see “Check the Battery Pack”

Pin 1: +19 to +20.5V (Centre pin)
Pin 2: 0V, Ground (Shielding / Surround)


Check the Battery Pack
To check the battery pack, do the following:
From Software:
1. Check out the Power Management in control Panel
2. In Power Meter, confirm that if the parameters shown in the screen for Current Power Source and Total Battery Power Remaining are correct.
3. Repeat the steps 1 and 2, for both battery and adapter.
4. This helps you identify first the problem is on recharging or discharging.

From Hardware:
1. Power off the computer.
2. Remove the battery pack and measure the voltage between battery terminals 1(+) and 6(ground).
(Terminal 1 is closest to the edge, Terminal 6 is closest to centre)
3. If the voltage is still less than 7.5 Vdc after recharging, replace the battery.

To check the battery charge operation, use a discharged battery pack or a battery pack that has less than 50% of the total power remaining when installed in the computer. If the battery status indicator does not light up, remove the battery pack and let it return to room temperature.

Re-install the battery pack.
If the charge indicator still does not light up, replace the battery pack. If the charge indicator still does not light up, replace the DC/DC charger board.

Have tried removing the battery and mains power, left for half hour and still nothing. Output of power pack is correct at 19vdc. Battery is fully charged. I'm running out of ideas!

Yeah had the same thing and it was the mainboard. and Sexkitten is right it cost upwards of $!k so not really a feasible option. I gave up on it and built a new system

Ok thanks for your help everyone. Obviously i have all my data on its hard drive. If i install it into another notebook will it load up as my computer (using my os etc)? Just so i can copy everything to disk?
