Occasionally, I try to turn on my computer and the power light comes on for about one second then turns off and and the computer will not start. It does this on AC power and battery power. The next day I try it again and it starts normally.

Re: computer will not turn on
This could indicate a bad battery, or bad memory chip. Try starting without the battery. If this doesn't work, then try takeing one or the other memory chips out. If the problem persists, then it may lie within the power management system on the motherboard.

With the little bit of information presented, it appears that this is possible a power supply problem. One thing you can try is to unplug the power adapter from the laptop, remove the battery, then plug the power adapter back into the laptop. Then try to turn it on. If everything comes up normally, then the problem points, potentially, to the battery.
Hope this helps!
Disconnect the AC adaptor from the laptop and remove the Battery pack from the Battery bay. Then, remove the RAM module and reinstall it after cleaning the RAM slot. Next, connect the AC adaptor to the laptop then try turning it ON. Please make sure that the AC adaptor is connected to a functional wall outlet. If the laptop still doesn't turn ON then you may try cleaning the Battery bay and the metal contacts in the battery compartment then insert the battery and try turning ON the laptop. If the laptop still doesn't turn ON then the issue is with the power supply unit.
The inverter inside the lcd panel is most likely your problem. Try removing the whole lcd screen from the laptop if you are capable and run it with the external screen to confirm. leave the lcd switch off (this lcd switch above the power button turns the lcd inverter on and off)
I dont have that much experience with Acers, but one thing I do know is that when laptop batteries are really drained [especially if that happens when applications were running] the system goes into this unconscious state and only power up once the system has enough battery power. However, that doesnt imply that the problem is always battery related. sometimes harddisks 'lock' and refuse to come out of that state until you do something like hold down the power button for like 10 seconds' or even manually remove the CMOS battery located on the motherboard
Try run the computer on main power and check.
If it still does not run then it is issue with the power circuit on computer and make sure this check the power adaptor working properly by connecting to another computer. "It is turning out to be hardware issue. Contact gateway then
