Dell Latitude 5501 Bios password

[drips]

Hello,

I'm new here, I received a Dell 5501 which has a locked bios.
I tried unlocking it trough bios-pw.org, but seems like this doesn't work with the service tag suffix "8FC8".

If i understand correctly this is the procedure?:
1) Open up the laptop, remove battery and locate the BIOS Chip
2) Use a ch341a programmer, and take a backup of the bios.
3) Upload the bios backup here
4) Receive "updated" here on the forum
5) Download the new bios to the chip

Is this correct? Any risks involved in this?
Thanks!

1 to 5 - yes. In general, the procedure is described correctly.
The only problem is the successful reading of the chip, and accordingly its writing with the unlocked dump - this programmer is notorious for its erratic performance.
Being cheap in buying tools hides some unexpected surprises.

Correct, remove all battery ( main and CMOS battery ).

Thanks for the feedback @Vesko356 & @hoaca388.

I will order an TL866II programmer, is it necessary to desolder the chip or can i use the clamp adapter & program it "in circuit"?

I prefer to not desolder..

Thank you.

In general, for the best result chip must be unsoldered from the board, but it can also be done in circuit - the result depends on the quality of the clip used for this purpose.
