Hi everyone, welcome to HowFixit. In this video guide, I gonna show you how to force reset bios
settings on Alienware M17 R2 laptop To disassemble this laptop, you will
need the following tools: Phillips 1 screwdriver
Plastic opening tools Tweezers
I also recommend using a magnetic mat during the repair process, which is especially useful in case
of this laptop. Throughout this disassembly, keep track of each screw so you can put them
back in the right places - this will help successfully reassemble your device. And
don't worry about losing any of screws, all of them will definitely remain on the magnetic mat.
In the description, I left links where to buy all necessary tools.
Turn the laptop over and remove all the screws on the bottom cover.
To reset the BIOS settings, you need to disconnect the main battery of the
laptop and the battery that supports bios memory.
Disconnect the BIOS battery for a couple of
minutes. This will help reset the BIOS to factory settings.
If the laptop cannot save the BIOS settings, then you need to replace the battery with a new one.
Disconnecting the bios battery can help if the laptop freezes when turned on during the
initialization of devices, but you should not expect this method to reset the bios password.
To reset the bios password you need a programmer and the ability to work with a soldering iron,
therefore, this is a separate recovery process that requires much more repair experience.
Well, that's all, you were on HowFixit and see you guys next time!
