If you ever forget the BIOS password of an Acer T250 notebook here’s a method to reset it: Open the notebook and look for the DIP switch located below the keyboard. Set switch number 1 to the “On” position. Power on your notebook. Power off again. Reset switch 1 to it’s original position. Re-assemble the notbook. Store spare parts in a safe place. Done. Might also work for other Acer notebooks but no guarantee given.

This worked for my Acer Travelmate 2413WLCi. However the dip switch was behind a decal above the key board. Now I have to work out how to beat the eRecovery password.
Acers really suck.
Hi Guys,
Acer notebook, clear Cmos password solution
After much searching for a solution to this problem i actually got a hold of a technical manual for an Acer 5100 AMD 64 x2 Notebook. The CMOS clear setting on some of the 5100 series laptops is located underneath the ram sticks, from the underside of the laptop. You need to remove the ram sticks in order to find this point. Rather than a traditional jumper it is just a straight point which you’ll need to short. Shorting both points on here will clear the cmos for you. The point is labelled “JOPEN1″ on the circuit board. I have a link here to an image displaying it’s location on the board.

It’s also possible to clear the cmos by removing the battery from it’s connection for approximately 20 minutes by using a soldering iron, being very careful and then resoldering to the point. Make sure and be very careful not to remove all the solder from the circuit board otherwise you’ll be in a world of hurt.
Cheers,
Gav.
