…one man's contribution to the Weeeeerly Wild World
A client had somehow found themselves locked out of their laptop computer due to there being a BIOS password.
Switching the Toshiba Satellite C50D laptop on would immediately present the “Enter Password” message (before the OS can be instructed to load):
After three attempts the system restarts and you’re back to the same:
Normally I would either short some pins on the motherboard, or remove the CMOS battery for a few seconds to clear the BIOS settings, but this is a new laptop and there is no CMOS battery to remove (just a blank area on the board instead).
I looked online for a solution and found steps (in the form of a Youtube video) for clearing the CMOS on one particular laptop which involved locating two soldered contact points and shorting them (I used a bent paper-clip) for over a minute during a few routines with a RAM module out and then in, powering the laptop with a mains lead for the procedure. I found some tiny contact points labelled JCMOS (not the same as the example I found) but the procedure didn’t work for me.
Another possible solution was to short each of the contact points in turn with the chunky RAM slot grounding point (near one of the two clips), but still no joy, so I’m posting this here in case someone stumbles across it and can suggest something I can try in the future.
EDIT: Raul kindly contacted me with the steps he took. His comment is below but in Spanish, so here is how I have translated it – I don’t have the opportunity to try his suggestion:
To reset the password/delete the BIOS:
1. Remove the hard drive
2. Leave the RAM installed.
3. Withdraw the battery
4. Get a bent paper-clip and make contact with the two JPW contact points. [Here is an updated image:]
Remember that the JPW are not those of JCMOS; the JPW contacts are little more away from the JCMOS and are immediately [adjacent to?] JCMOS RAM.
5. With the charger plugged in keep contact with the JPW points, then you have to turn on the laptop while removing the paper-clip. Then appears the Toshiba logo on the screen, and you are ready – the password is cleared.
