Did you get any signal on the External Monitor? or nothing with only black display? There are several reasons, once you boot the system, listen the boot up sound very carefully and make sure it normally boots up.. Is the hard disk light blinking? If you think the system is not booting up properly or seems stuck at some point, you need to first check the Ram and the Hard disk. Turn off the machine, Remove the battery, unplug the Charger and clean the interfaces (gold contacts) with a brush or cotton bud or a cloth dampen with alcohol or acetone etc...etc.. Once they are cleaned, check the connectors on the motherboard (Ram and Hdd connectors), clean them with a brush... If a Wireless Lan card is installed, reseat it. Now reinstall the Ram (if you have multiple Rams installed, try with only one) and boot up the system without the hard disk, if there is no damage on the motherboard or if there's no bios or display issue, it should show something on the Display...(the black bios/system screen), if so, reinstall the other ram and try again (make sure the system is power off before you reinstall the other Ram or any component, you need to reboot the system everytime you install a new hard to test the status.). Again, check the display, can you see the bios screen (black screen with white text or the Acer Bios screen). If so Turn it off and install the hard disk, now reboot the system, again check...........................

If the system fails once you install the hard disk, then you try booting from a Windows CD, maybe windows xp or any windows cd you can get...if it's successful, you hard disk is bad or corrupted or is damaged.. try reinstalling or repairing the windows, else you need to replace it.

The second cause could be the ram, if in the first place it didn't boot up, then swap the Ram or use a new Ram, that should show you the result about Ram, even if changing the ram isn't helpful, I would assure that it's the Graphics card issue, your only solution is to get it repaired from the Acer service center.

If you can assure that there's nothing wrong with the Graphics card, then it must be the Bios, in the same way, bios can't be repaired from the end users, it needs to be repaired in the Lab, means Acer Service Center.

If you need further help, let me know.

Good luck.

Thanks for using FixYa.

My acer aspire won't power up

Try to connect your PC with the battery on the power outlet if it lights and charge normally. If the lights still orange, try to open the hard disk case and pull it out then try to put it in place again. If still doesn't go, try the memory card and clean it.
But I suspect that the battery has been overly charged. Try to look for another battery of the same model if it works with another and new battery.

Bluetooth power


to turn it on just press the button or pull the switch, if noting happens or the blue light doesn't light up and the computer doesn't react, it basicly means the computer didn't come with a build in bluetooth device, but has the option for the customer to later install one in the expasion slot inside the laptop.

Let me know if you need anything else.
