How to reset BIOS password on Sony Vaio?

Question

System administration

They asked me to install win 10 on a laptop (VPCEH2M1R), bought from hand, now there is win 7 not native, pro version, what kind of assembly and 50GB is allocated for the system disk.
A password is set on the BIOS, I tried to install it from dvd, hdd is not visible.
I found information on the Internet that resetting the battery will not help, since the password in the non-volatile memory and in the BIOS may have settings that prevent the OS from being installed on a clean one.
I found a password generator for the BIOS, but there you need to enter the second part of the laptop's serial number, in my case it gives out a sixteen-digit code that changes every time after turning it off.
The only option is to call tech.pod. Sony, but I'm not sure if the laptop is registered and of course I don't have the details of the first buyer.
How to be?

Answer 1

I came across a similar situation and also with a Sony laptop.
I don’t remember exactly what I installed XP or 7. I did this:
removed the HDD installed on my laptop
installed (started the installation) the system before the first reboot
on reboot turned it off and moved the disk back to Sony
It turned out that the files prepared for installation were already copied, but the hardware detection phase hasn't passed yet. After continuing the installation on Sony, all the equipment was determined and the system booted normally.
In your case, you can do it easier. You need to remove the HDD, on another computer copy the contents of ISO or disk from 10 to a folder on the disk that will be the system one (for example, in C:\W10) If the partition is small, then stretch it, for example, using MiniTool Partition Wizard Free.
Then return the disc to Sony. It will boot into the system as it is and from it run the installation of 10 from the folder.
Old user profiles and programs after installing the new system will remain in C:\Windows.old
Yesterday I just changed 10 to 7 on the ACER ASPIRE ES 15 laptop without a floppy drive and without connecting a flash drive.
There was no floppy drive according to the specification, and the installer 7 did not see the USB ports in any way.

Answer 4

You can try to write a letter to Sony asking for password recovery, they can help, or they can refuse (other manufacturers gave me codes).
I can help with links to a forum where they help (not always for free):
