ASUS TP500LA BIOS request/repair/merge?

[jbonavita]

Hi, my laptop wont boot at all
With original bios no POST, only LED lights
With alternative BIOS from model TP500LN (flashed via programmer) the notebook works again
Some issues
A- with bios from 500LN, it won't update from bios of model 500LA (from 500LN v203 to 500LA v300)
B- If updated from 500LN version 203 to 300, the battery stops being recognized

Things I tried

1- Update / clear ME: Took the non working bios, made a backup, and did this: https://www.badcaps.net/forum/troubl...-guide?t=88533
to no good results (same behaviour from the original BIOS)

Things I noticed

Backup bios size : 8 MB
TP500LN donwloaded BIOS from this forum : 8MB
Bios for model TP500LA downloaded from ASUS support : 6 MB

So, Im in need of:
- A normal backup of a working bios for TP500LA (8 MB) for direct flashing
- A merge from the ASUS webpage 6 MB BIOS and the part of the TP500LN BIOS that made it work
- Repair or something my original BIOS

As of now, Im thinking to cut a part (2 MB) from the 500LN bios and merging to the 6 MB 500LA to make a 8 MB one, but I dont know how
Thanks in advance

He was referring to the serial number, but it`s not TP500LA-DH71T , the serial is about 15 digits long

Flashed it and the notebook boots fine, but the easy flash option in BIOS is showing " please plug in battery and its remaining capacity should be more than 20%. System doesnt permit flashing BIOS. Please press any key after pluging the battery"

Pressing a key does nothing, the battery is internally connected already

Tested merge.bin. and worked flawlessly, the notebook boots as normally do, no delays etc. But now is has no serial number installed. I have battery problems and MyAsus app doesn´t recognize this machine (to try some calibration, etc). It is possible to re-add the SNID posted above? thanks
