Hello,
I have the Acer A114-31-C6QA, and motherboard model is the "DA0Z8PMB8E0 REV-E". The laptop doesn't turn ON (only power ON light is present). The 5V and 3.3V are present. I beleive that the problem. First I tried to re-program the bios chip "MX25U8033EM2I". I use the programmer CH341A and the RT809F but both couldn't programmed (give an error). I bought a new chip "MX25U8033EM1I" with 1I instead of 2I (I read on the datasheet that the only different is the size of the chip). Now the problem is that I re-program the new chip with the 1MB file but the power ON light now don't light.
Also, I re-program the "25LB64CS1G" chip with the 8MB file. This laptop has double bios?
I can't understand what happens and I can't find any other problem on the hardware.
Does anyone knows how can I certain that the chips that I re-program have the right bios?
