Before you start

1) Read through the owner's manual for your particular Acer Aspire laptop to determine what kind of CMOS battery you need.

2) Purchase the battery through Acer or a local or online computer parts dealer.

3) Turn the laptop off and unplug it. Also unplug any external hard drives, cameras, or other external devices.

4) Turn the laptop over (bottom facing up), then touch something metal to remove static charge.


Removal of the CMOS battery

Remove the Phillips screws that secure the motherboard cover (refer to your owner's manual if necessary), then release the cover from the clips on the bottom of the plastic casing. Lay the cover aside then locate the CMOS battery cable on the right side of the motherboard. Unplug the cable then remove the battery.


The battery should look something like this

Plug the new CMOS battery cable into the motherboard. Slide the battery partially under the laptop casing (somewhere to hold it in place), then align the cover with the slots on the bottom of the laptop housing. Replace the screws then turn the laptop back over.

Finalizing
1) Turn the laptop on.
2)Enter your BIOS (usually by pressing the "Delete" key) before the operating system loads.
3) Follow the BIOS prompts or refer to your Acer Aspire owner's manual to reset your time, date and desired system settings.

Reason: Anytime the CMOS battery is unplugged for more than a few seconds your BIOS will be reset to the default manufacturer settings. If you make any changes to the BIOS that cause problems with your Acer Aspire, unplug the CMOS battery for 3 to 5 seconds to correct the problem.

Region setting on Acer Aspire 8920


Older DVD drives use RPC-1 firmware, which means the drive allows DVDs from any region to play. Newer drives use RPC-2 firmware, which enforces the DVD region coding at the hardware level. These drives can often be reflashed with hacked or Australia and New Zealand (hardware region coding prohibited by law in these countries) RPC-1 firmware, effectively making the drive region-free. However, this usually voids the warranty and can render the drive inoperable if something goes wrong... better contact your laptop manufacturer regarding this
