Thread: how to reset BIOS password on Acer 5315 lappy?


Forum: PC Problems

Evening all, Does anyone know how to reset the bios password on a Acer Aspire 5315 laptop? I found the cmos battery, well wot i think it is but its soldered onto the motherboard so left that avenue alone as my soldering skills are pants. I tried also a programme called CmosPwd but that didn work for me either - anyone else got any idea's? Does anyone by any chance know the backdoor password for this make and model of laptop? There are many floating about but I only got two attempts

    Question how to reset BIOS password on Acer 5315 lappy?

    Evening all,

    Does anyone know how to reset the bios password on a Acer Aspire 5315 laptop?

    I found the cmos battery, well wot i think it is but its soldered onto the motherboard so left that avenue alone as my soldering skills are pants.

    I tried also a programme called CmosPwd but that didn work for me either - anyone else got any idea's? Does anyone by any chance know the backdoor password for this make and model of laptop? There are many floating about but I only got two attempts left I'm pretty sure before the function is disabled as I tried one pasword already, so I beleive I have two more attempts left.

    Any help with this would be great. Thanks for your time.

    if you opened it up check to see if there is a jumper on the board (a little red,black,blue,green) clip that looks like a little rectangle...it connects the points together, if removed set's it back to factory settings so date andtime will be wonky...but an easy fix try it mate

    I've just had to remove the bios password from an Acer 5315. I couldn't find any software that worked (I tryed CmosPwd like yourself). So I desoldered the cmos battery and soldered it back again. That worked. You only have to desolder one leg, it's easy. Alternatively you could try and short the battery out with a piece of wire for a few seconds. That may work but I don't know.

    for people who don't know the inside of this computer, there are no jumper connectors on the board, and the battery is soldered directly to the board right next to the cmos.

    its rediculous why some manufactures trying to get more money for such services
    also its not realistic that I or my friends will keep prove of ownership for every piece of hardware we own

    "To reset the CMOS battery on a Acer 5315 is to short out the CMOS battery on boot up by using a screwdriver on both leads of the battery. This will not harm the laptop."

    this did work for me
