The removal and replacement instructions can be found in the dell service documents available at support.dell.com. You can look it up by service tag or model number. But in short, the procedures are. 1. Remove the hard drive, then remove the keyboard. The keyboard is removed by removing the 5 screws on the bottom of the laptop marked with a "K" beside them. Then the keyboard can be removed. be careful not to tear the ribbon cable, and you do not have to remove the ribbon cable. The battery will be in the center of the opening, it will have a white plug that plugs into the keyboard. Contrary to Ayyasam's recomendations above, it is not necessary to remove "all" the screws on the bottom, nor is it necessary to remove the bottom of the laptop. It should be a 5 minute project. Again for any Dell item, the factory repair manuals are available online, and have exact instructions including pictures and diagrams.

Happy Computing

Bios reset for acer v5-531-6119


First step - try and remove the CMOS battery located somewhere inside your laptop - looks like a watch battery but a bit bigger. Take that out for 10 minutes, put it back in and it *might* reset the password. If not, post back, there may be something else we can try

All laptops have a CMOS, or "Complementary Metal Oxide Semiconductor," battery.
The main purpose for the CMOS battery is to keep the system time, date and BIOS settings even if the computer is turned off or the main battery dies.
Individual Acer Aspire laptop models differ somewhat, but the general steps are the same when replacing a dead CMOS battery.Preparation

Read through the owner's manual for your particular Acer Aspire laptop to determine what kind of CMOS battery you need.
Purchase the battery through Acer or a local or online computer parts dealer.
Turn the laptop off and unplug it.
Also unplug any external hard drives, cameras or other external devices.
Turn the laptop over (bottom facing up), then touch something metal to remove static charge.
Removal
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.
Installation
Plug the new CMOS battery cable into the motherboard.
Slide the battery partially under the laptop casing 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.
Settings
Plug the laptop in and turn it on.
Enter your BIOS (usually by pressing "F1," "F2," F10" or the "Delete" key) before the operating system loads.
Follow the BIOS prompts or refer to your Acer Aspire owner's manual to reset your time, date and desired system settings.
BIOS Reset
Any time 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 3-5 seconds to correct the problem.

Computer was locked


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 dont 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.

My acer aspire 5542g keyboard is locked, how do i unlock it?


Try using Fn + F7. It turns the touchpad on and off.

Another solution is maybe CMOS or BIOS has locked the keyboard and touchpad and that maybe resetting the CMOS/BIOS by jumper or removing the battery will unlock them.

BIOS password locked


Try to reset the CMOS using CMOS jumper reset. Look this in its manual how to do it.

Or take out the CMOS battery out of its socket then place it back again this should clear CMOS and restore to its default setting. Without the BIOS password.

Locked out of BIOS


unplug everything from the laptop, remove the battery from the back and hold the power button for 30 seconds. On most computers, this will reset the cmos without needing to remove the cmos battery.
