Hello, mine is Lenovo G400, how to factory reset 5

The computer is factory reset, one is the SIOS factory reset, and the other is the hard disk factory reset.

1. Restore SIOS to factory settings.

Sios factory reset, because its Sios version is different, the operation method is not exactly the same, as shown in the following figure:

Select the Load Optimized Default item and click Save to restore the factory settings.

There is a simple and common way to restore the factory settings of SIOS: take out the CMOS battery of the motherboard and put it back on after 10 minutes, so that the user's setting information is lost due to the intermittent power supply of the CMOS, so as to achieve the purpose of restoring the factory settings.

2. Factory reset the hard drive.

Using partitioning software, delete all partitions.

Dear Lenovo users, hello!

One-click recoveryThe data of the general C disk will be restored to the factory state, and the data of other disks will generally not be affected, but there will be risks, it is recommended that you completely back up the data and then restore it with one click, providing you with a one-click recovery video tutorial.

It should be noted that during the restoration process, the laptop battery should be fully charged or connected to a charger.
