Locked BIOS need help

Recommended Posts

Posted · Original PosterOP

I have an Acer Aspire 5 515-51G
I bought it and after repasting I tried to enter BIOS.
Try to figure out how that turned out.
Half an year later I still can't access my BIOS.
Tried BIOSPW.ORG, can't even get the laptop name right

MOBO: KBL CHARMANDER-KL
Bios InsydeCorp (no info on the internet about BIOS passwords)

v1.21
 

Thank you!

Have you tried clearing the bios by removing the CMOS battery for a few minutes?

This mobo doesn't sport a CMOS battery but the laptop has a hole in the bottom for a BIOS reset.
No it doesn't help I think its an EEPROM chip.

Since it is a laptop, I would try something like this.  First, unplug the machine from the power supply.  Don't want any power supply cables connected.  Second, remove the battery from the laptop.  If it is like the Acer laptop that I have, the battery is removable from the bottom of the machine.  Next, press and hold the power switch to turn it on for a couple of minutes and then release the button.   Do this several times.  On - off, on - off.  Several times should do the trick in making sure that any caps on the mobo are completely discharged.

 

Now that you have done the above, go ahead and reinsert the battery in the bottom of the machine. and once that is done, go ahead and plug the machine in to the wall.  You should be able to enter the BIOS when you turn on the power, just make sure that you hit the right key or keys to get into the BIOS.  On my laptop, it is the delete key.  Just spam the key and that should get you there in the BIOS.  Give this a shot and drop us a note here in the forum to let me know if it worked.

Will this work if it is an EEPROM chip?

I"m thinking it should but I can't guarantee anything.  Just going by my own personal experience with my own laptop.  My laptop is an Acer Aspire 7741G-6426.  Few years back I had to replace the screen, now that was a neat trick for sure.
