Well you can reseat the RAM and check if that does not fixes the issue, it could be an issue with the system board . You can contact Acer support line, if the unit is under warranty you can have system board replaced.

What stops computer from starting up


turn off the notebook. take a regualr desktop monitor VGA or LCD monitor and plug into the notebook (make sure to power up both the notebook with AC adapter and power cord for monitor). Turn both on and you should see video on the desktop monitor . if you do not see anything, i would hint at the fact that the notebook screen may be bad. Do you hear the hard disk drive spinning when you turn on the notebook ? if so, thats a good indication that the mainboard is still working and that the LCD screen on the notebook is not functioing . You will have to replace the LCD (notebook) screen

remove the battery and power cord then remove the battery on the mother board, hold down the power button for 60 seconds to drain the capacitors, if that doesn't work it's the motherboard that should be replaced.

Acer 290 bios password reset

Hi, Keith.

Remove the bottom of the notebook.

See if you can remove the CMOS (round, silver) battery for 30 minutes.

If not, on the motherboard, note the bank of four switches. Normally, they would be off. I believe that if you turn on switch 3, the BIOS and boot password would go away.

Hope this helps.

Acer 5570 - Power switch is not working

Try removing the power supply (from the wall) and the battery pack. Hold down the power button for 30 seconds. Plug the mains power (from the wall) back in and then press the power button. It should work. Then you can replace your battery pack. Don't know why it works but it has worked for me in the past. Good luck!
