I have a compaq evo d320, the previous owner had set a password on the BIOS/utility set up, I can login into it by just pushing enter 3 times on at password stage then utility loads, but I can't change anything in it, as if I'm locked out of changing any thing.
I tried a method of removing battery, it did kinda look like it had reset but then password page came up again upon entering utilties, plus it also said that the CMOS was invalid.
What else can I do to resolve this issue and thanks in advance.

Re: Reset BIOS password
Ok, this time try to reset the bios using the jumper (small bit of coloured plastic near the battery) move the position of the jumper and hit the on/off button, the computer should not start if you have done this right, move the jumper back to its position and start the pc, go straight back into the bios and set the date and time, hit F10 and ok or yes and you should have full control of the bios. if there is no jumper, remove the battery again for 10 mins and make sure the power cord is removed from the back, hit the on/off button a few times to drain any residual power, after 10 mins replace the battery and do what i told you to with the bios

You can remove your bios password by reseting your CMOS battery or jamper. You need to open your notebook remove first the battery and all screw
at the back of your notebook. You can see there a CMOS battery together
with the CMOS jamper. Just read it you can read CLRSCR which means
clear cmos, just pull it with in 10 seconds and insert it back. Now you
are done to reset bios.
For that you need to reset factory defaults settings for bios. For reset bios u have to open back side of your laptop then u find motherbord circuit there. pull cmos cell on motherbord for 15 minute then it reset to defaults. Also u can reset with jumper settigns read carefully on mother bord there is 1 jumper near cmos cell u read there " bios reset or clear" It is on 1-2 position right now set it in 2-3 position then power up then all bios settings are reset. then again set it in 1-2 its original position. Then it not want password.
the only way is to open the laptop up and there will be a small watch type battery, quite big but flat. it will be on the motherboard. take the battery off the otherboard for at least 10 seconds and then put it back in. this should reset the bios to factory default.
Do the following steps -
- Remove the laptop battery
- Remove the CMOS battery
- Leave it for idle for around 15 minutes
- Put the CMOS battery in
- Boot the laptop with AC power
- Then put the laptop battery in.
- The BIOS pwd would have been reset now
- For troubleshotting the battery - Go into BIOS and run the Battery Caliberation tool
Hope this helps.
Removing the Time of Year battery will clear the BIOS password. It is located on the underside of the n610c behind the panel covered by the Microsoft COA label. A small phillips screwdriver is required to remove the two screws on the panel. Carefully lift the BR1225 battery with a small flat blade screw driver.
After 10 minutes re-insert the battery. The BIOS Password should now be cleared, as well as other BIOS settings, the time and date.
