I've just acquired a Acer Travelmate 740 and am about to install more RAM. The only trouble is, should i need to get into the BIOS, i can't as there's a password set and i don't know it. Is there a solution to this for this model?

Funnily enough i compiled cmospwd earlier today but found the following in the source (my case):

printf("Warning: if the password is stored in an eeprom (laptop/notebook), the password won't be erased.\n"

Open in new window

modern laptops keep the password in a security chip (anti-theft)
so you need to know the password, or contact ACER and show proof of ownership

but in most cases, adding ram does not require you to go in the bios, unless you need to modify it's settings

So disconnection of CMOS battery would be useless? And nobus, what would be your opinion on the usefulness of cmospwd?

If you can actually hit the CMOS, that would be great.  I read that it is practically soldered to the board (I don't mean literally).  

You could flash it with jumpers.

I've been trying to find the service manual, as opposed to the user manual, without success

That's the User Guide, not the 'workshop manual'. The latter type of manual for Acers includes such things as exploded diagrams of the motherboard

>>If you can actually hit the CMOS ...

Will that be of any use? If the password is held in a separate eeprom then will doing anything with the CMOS, such as cutting its power supply, be effective?
