Hello everyone and Welcome to HowFixit.
In this video I gonna show you how to force reset bios settings on Dell XPS 15 9575 laptop
To disassemble Dell XPS 9575 you will need next tools:
Phillips 1 screwdriver Torx T5 screwdriver
Plastic tool Tweezers
Also I recommend using a magnetic mat in repair process and laying out each screw step-by-step
during disassembly, which is especially useful in the case of the Dell XPS 15 9575. This
laptop has a lot of screws of different sizes and it is very important not to confuse them
during assembly. In the description, I’ll leave links where to buy all the necessary tools.
Turn the laptop over and remove all the screws on the bottom cover.
Next, take a plastic tool and begin to open the case of laptop.
I recommend using a plastic tool so as not to damage the laptop case when you opening.
Disconnect the battery cable from the motherboard.
To reset the BIOS settings, you need disconnect the battery that supports bios memory.
Disconnect the BIOS battery for a couple of minutes.
This will help reset the BIOS to factory settings. Disconnecting the BIOS battery
also can help if the laptop freezes when turned on during the initialization phase of devices,
but you should not expect that this method will 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 and that requires much more experience in repair.
If the laptop cannot save bios settings, then you need to replace the battery with a new one.
Well, that's all, you were on HowFixit and see you guys next time!
