Acer 5552-7819 Bios Problem

XXXXXXXXXX · Jun 23, 2014

I recently bought a used acer 5552-7819. There is a bios password in it. I found out after I got it home. The former owner does not know what the password is. I have spent 2 days reading (till my eyes bleed) about this issue. So for I have tried.. removal of mother board battery, shorting the battery, removal of both batts and pressing the power button, tried esc on boot, f12 on boot, f10 on boot, f8 on boot, upgrading the bios to 2.4 and then changing the values in the ini file.. so all the values have been to 1 from 0 to flash the bios on start up, ( which is part of this method http

/www.citronix.net/blog/how-to-remove-a-bios-password-from-an-insyde-h2o-efi-bios/ ) I have tried cmos wiping tools etc etc etc

I mean I have tried everything I have read and nothing has worked. Does anyone have a method for removing the bios password this guy put in? The problem is .. I cant access the bios to change to boot priorities.

Thanks for the help

I think you need to press f2 to choose boot priority..

The default pasword is 6 "zeroes"

The bios reset is in the mainboard, or you can remove both batteries and leave it out for 1 hour to reset tge bios.

Ok thanks... yes f2 is how to access the bios.. that is where it needs the password. I did take the batteries (both) out for over 24 hours.. password still there... I have not seen the "6 zeros" thing before... will try it right now...fingers crossed!!

Ok tried 6 zero's... no luck... halted on try #3. No hash or error code shown with this bios. Just got the halt screen. Thanks for the suggestion.

Thats odd..

After removing the battery, there should be no way for the bios to retain its settings...

Try to remove the battery, then use the ac adater to boot the system.. Without the batteries.

Thanks for the help... I did that already.. no go... I think this the insyde EFI bios?? Screen goes so fast I cant read it.. any way I think the bois is the one where in stead of it being in the cmos.. its in something called an epprom?? I tried this tool http

/boginjr.com/it/sw/dev/de-cmos3/ but must confess I don't really understand what I am doing with it... I thought doing a total cmos wipe with it would brick the machine.. but it didn't... it still fires up into windows.. but I still cant access the bois to change the boot order.

that would be your best bet at the moment..

i would not recommend disassembling the laptop just to jumper reset the cmos on the mainboard.

Hi, it took me 5 minutes to find out how to remove the password for this laptop, however I can't tell you because it's against the rules of this site. We can't verify if its not stolen, even if you said it's yours. Sorry.

Welll maybe you could be a nice guy and pm a link?? I spent 2 days on this so far...with no solution. I googled it as well and within 5 min found tons of solutions... none of them worked. That's why I need the help. I have seen bios lock out questions asked and answered a billion times on this forum...read most of them.. only problem is none of them worked. So if you could be a nice guy and let me know what to do .. that would be great. I am not locked out of the lap top. It starts and runs.. I just want to change the boot order.

Thanks X
