Setting up a password on the Acer Aspire prevents others from accessing the computer without permission.

If the user is unable to supply the correct password at startup, the computer will lock the hardware and fail to boot.

This security measure is a useful feature, but it can create serious problems if you forget the password.
Basics

The Acer Aspire stores the password in a component called the complementary metal-oxide semiconductor.

This component is integrated into a random access memory chip embedded on the motherboard. The CMOS holds data that the basic input/output systema critical software utility that controls how the computer operates at startupaccesses when the computer boots.

If the BIOS detects that a password is registered in the CMOS, it will prevent the computer from booting until the user enters the password correctly.

Depending on which model of Acer Aspire you own, you may be able to clear the CMOS manually.

Contact Acer before attempting to clear the CMOS, as opening the computer without permission could void your warranty.

Desktop Models

Some Acer Aspire desktop models come with a jumper that is used to clear the password and other settings stored on the CMOS.

This jumper is located on the motherboard and is often found next to a label such as "JBIOS1" or "CLR_CMOS." To clear the CMOS using the jumpers, turn off the computer, disconnect the power cable and remove the case cover.

Remove the jumper shunt from pin 1 and pin 2; then place the shunt on pin 2 and pin 3. Return the shunt to its initial position after 10 to 15 seconds.

If the Aspire doesn't come with a jumper to reset the CMOS, the CMOS can be reset by removing the lithium coin-cell battery instead.

Removal is accomplished by pushing down on the tab securing the battery to the motherboard and lifting the battery out of its slot.

Leave the battery out for 24 hours, and then return it to its original position with the positive sign facing up.

Laptop Models

Resetting the CMOS password on an Acer Aspire laptop is much more difficult than resetting the password on a desktop.

Disassembly steps vary from model to model, but on most models, you'll have to take apart the computer to access the CMOS battery.

Don't take apart the notebook if you don't have experience disassembling PCs.

After turning off the computer and disconnecting the AC adapter, take out the battery (different from the CMOS battery).

All visible screws must then be removed from the bottom of the notebook.

Remove all components stored to their separate compartments on the base of the notebook.
Turn over and open the PC.

Lift up the switch cover and remove the screws securing the keyboard to the PC, if any are visible.
Remove the keyboard.

Remove the screws securing the monitor to the hinges, and then set the monitor aside. Disconnect all visible cables connected to the motherboard; and then remove the screws from the top cover.

Remove the top cover to reveal the motherboard.
Locate and then remove the CMOS battery.

Leave it out of the notebook for 24 hours; then reinstall it and reassemble the Acer Aspire.

Other Options

If removing the CMOS battery fails to clear the password, or if you don't feel comfortable with the idea of opening your computer, you might be able to gain access to the computer using a backdoor password.

These special passwords were implemented to allow technicians to access locked computers. Not all models recognize backdoor passwords.

Most Acer Aspires use the Phoenix BIOS, and backdoor passwords for this BIOS include "BIOS," "CMOS," "phoenix" and "PHOENIX."

All of these passwords are case-sensitive.

Acer desktop mouse,keyboard not functioning, monitor also not wor


If there is no display on the monitor, then your computer is not sending a video signal to the monitor.
This could be caused by a bad video card or some other hardware problem. I would open the case and disconnect all the devices (hard drive, CD, etc. Leave only the CPU, memory, and video connected. You could leave the keyboard and mouse connected too.
If your computer then starts, you can start to add devices (after turning the computer off) one at a time.
If this doesn't work, then you are looking at replacing the motherboard or just the video card if that is possible.

Computer will not load up - frozen on acer start screen?


Are you sure the monitor is plugged into the correct port? Also, check the monitor cable for bent pins. A small move shouldn't make this kind of difference. Eliminate that power strip and just plug the computer and monitor into an outlet.

go into the bios and make sure the USB controller are enabled, save settings and reboot if still same drivers are missing from the operating system, if you haven't got a password boot to windows and plug the keyboard in a different port to re-install the drivers. if you can't, does the computer support ordinary keyboards?

Its is saying that the operating system not found on my acer aspire 3050 laptop wen loading up. what is wrong?


Generally it means that Windows is not installed on your computer, or you have a floppy disk in its drive that does not contain a start up disk (assuming you have floppy disk drive).

Were you deleting any files during its last use?

My Acer Aspire T310 won't go past the Acer screen and the Keyboard and Mouse don't work


Yours may be a little old computer and the cmos battery (on the mother board)is drained out. Replace this battery. You need a working keyboard.

Two of the keys fell off. Its a acer aspire 3050.


the is an armature under the key that holds it evenly flat. make sure that is not missing before snapping the keys back in place.
If the parts are completely missing your best bet is to find a complete keyboard on an otherwise broken machine that is the same as yours.
good luck
