1. Mainboard failed

I wouldnt be suprised if the vga failed, my acer broke down on me 2 times, on the 3rd time it was too much and I sold the laptop.

SOURCE: acer aspire 5562 have no power and won't turn on

what repair shop does work at no cost?? ok first check the voltage from the power adapter, if you have or can borrow a test meter. i have seen these go bad and still seem to work!( incorrect amperage and- or voltage). or you simply have a failed motherboard .good luck !

Can you plug a external monitor into the machine, most laptops have that serial port. If montor comes on, you have bad display or connections, If not you have problems with laptop....Good luck

Check cable connection acer 4739


When you connect the power adapter into the laptop, does the power LED light up? If not then - The battery adapter or the adapter's power lead or the laptop's power socket could be faulty. Check power adapter's DC plug that connects into the laptop power socket with a multi-meter, the voltage should be slightly higher than the voltage that is printed on the label on the bottom of the adapter. If the voltage is zero or way below the voltage that is printed on the label then the power adapter is faulty and needs to be replaced. If the adapter is OK then connect it to the laptop and power it up, then look at the power/battery charging LED light and wriggle the power plug in the laptop's power socket. If the power/battery LED light flashes and in a certain position this LED light stays firm, then the power socket is either faulty or it has a dry solder joint where it is connected to the motherboard. This can be repaired but it requires the laptop to be completely dismantled to get at this power socket and repair. If you cannot DIY then I suggest you get a quote first.

My Acer Aspire 5720 wont power up, i have tried it with and without the battery, power goes to the power buttons led and fan for 8-10 seconds and then it cuts out ?


Motherboard problems. It's an Acer and they're notorious for having these exact issues about one year to two years after being bought.

Acer Aspire 5720 Laptop issues.


It could be the battery. So i'd try to find a store that sells batteries and replace the battery.
Manny laptops will shut off when the battery is dead. So if your laptop works without the battery and only connected to the wallsocket, it's definitely the battery.
With kind regards,

Acer 5920 aspire wont start


1. Remove laptop battery, optical drive, hard drive and ram. Remove external peripherals as well.

2. Make sure AC Adapter is not yet connected to the laptop. Pressand hold on the laptop’s power button for 10 seconds to drain the powerflea.

3. Connect the AC Adapter for laptop to a known good power outlet, check ACAdapter power LED if it is on. Try to sense if AC Adapter is not makinga bit of noise when it is plugin to the wall power outlet.

4. Connect now the AC Adapter tothe laptop. Check if AC Adapter LED stays on when it is connected tothe laptop. If the LED stays on means the AC Adapter is fine. If the ACAdapter LED turned off check the AC Adapter pin that goes to the laptopAC socket if it is loose.

5. If AC Adapter stays on after connecting to the laptop try topower on laptop. If no power LED comes on then this is motherboardproblem.

6. Before replacing the motherboard there is one checking needs todo. If you can open your laptop bottom part then good, do this whenlaptop is not connected to any power source. Try to reseat the laptopCMOS battery then try to power on laptop after, if still fails thenreplace motherboard. I hope this helps.

Acer Aspire RAM


There are 4 screws holding the cover on the bottom of the computer that allows access to the RAM modules. (This is the same cover that also covers the fan. The same cover with the ventilation slots.)

Simply remove the screws and lift the cover by the indent to the right of the battery lock.
