Re: Buffer size not equal to IC size
This was the first accident i was talking about
But now it's another chip
Because I wasn't sure which one was really the bios chip, so I thought if the bios has a battery it should be connected to the bios chip
I guess i was wrong but now what?
there's no hope for this laptop?...Leave a comment:

Re: Buffer size not equal to IC size
I just can't understand what is wrong with this laptop
It's seems to be on, the cpu is getting warm, and there's a nice melody for the diagnostic android app which says 'internal BUS error' but i can't see anything wrong with the voltage or resistance. then i found on lenovo forum someone who posted there's few pcs of this model with the same problom coused by BIOS update and i thought it's probably the problem with my laptopLeave a comment:

Re: Buffer size not equal to IC size
i'm pretty sure
i already erased another chip without reading by accident so i was really careful this time
But thats exactly the mystery i'm taking about
I also tried comparing this file with all the bios files I have for this laptop and none of them matched so i extreamly confused...Leave a comment:

Re: Buffer size not equal to IC size
I soldered the chip on the adapter board, and i selected the chip manually.
The chip is 10MB in every single software i tried even without the programmer pluged, so it's not the software and probably not the chip
I just don't understand how the reading was 16 if the chip is 10.
and what in the name of god is the actual bios chip?...Last edited by kings cross; 01-31-2023, 03:17 PM.Leave a comment:

Re: Buffer size not equal to IC size
It's a Lenovo L15
Board: GL4A5/GL5A5 NM-C741 REV 1.0
This chip is connected to the bios battery so i thought this is the bios chip
But when i read from it the file i got was 16MB as well so any way even if it's not the bios chip i can't write the original file back...Last edited by kings cross; 01-31-2023, 01:43 PM.Leave a comment:

Re: Buffer size not equal to IC size
I can see in colibri the chip is 1MBx8
but still the bios I was read was also 16MB so I really confused
What should I do now? i can't even write the original file back...Leave a comment:
