Acer Aspire 4520G not turning on

[lol64]

After turning off my acer aspaire 4520g,when I try to turn it on the hhd,caps lock and numpad lights light up for a split second, then it turns off.
I have tried to:
do a power reset for 5min
use it with only a charger, battery or both
removed both ram sticks

And it still doesn't turn on. Can anyone here help me?

Have you tried the following....

Try the following and see if it will turn on.

1. First make sure the device has been charged.
2. Unplug your charger cord.
3. Remove the battery.
4. Press and hold the "Power" button for 30 seconds and see if the device will turn on.
5. If it does, great, now plug back in the power/charger cord. (If it didn't turn on without the cord in, it should turn on once you it is in.)
6. Now put the battery back in.

Have you tried using a different power cord?

It may be in BIOS, the problem. When you hit the button to try and turn it on, starting hitting the F12 key and see if it will stay on long enough to actually go into the BIOS. If not that, it could be the charging circuit on the motherboard.

nope doesn't work

Were any changes made to the software (install, update, etc.), BIOS or hardware prior to the start of this problem?

nope

Have you checked internally for any damage, disconnections, etc?

Hi, obviously, the problem is on the motherboard, a component has burned and does not work as it should.
