I’m using a Dell XPS M1330. I have a HDD password set. Last Saturday evening, I had the following symptoms:
- upon entering the HDD password on startup, the system said “wrong password”
- after three failed attempts, it offered a system self test, which failed to find a HDD: “Error code 2000-0141 No drive detected”
- Accordingly, not even the BIOS screen showed the HDD
At this point I thought there were only two possibilities: a) completely broken HDD or controller, b) cosmic rays garbled the password on the HDD
Wrong. It is the keyboard. On two keyboard ‘columns’, when pressing one key, the keyboard adds the corresponding character from the other column. Example: I press b, and “bv” appears on the screen. I press “v” and “vb” appears.
Argh ^^ Better than a b0rked HDD, though, because I dont do backups every day.
My guess was that I’d have to replace the keyboard. But no. Removing the keyboard, disassembling it and cleaning out (as best as possible) the filth of two years fixed it. Took me half a day. – There’s still a bad aftertaste, though, because I didnt find the reason. Maybe cleaning was unnecessary, and just re-attaching the connector would have sufficed?
How many laptops have been scrapped because of a dirty keyboard, one wonders.
