Good afternoon, I have the programming of DGPU VBIOS ROM 1 Mb and the main board XMC25QU128BH 16MB.. Can someone help me review them? because I have only one boot of the computer and 2 seconds it turns off... the computer was working correctly began to update by windows and then did not want to turn on more... I tried some backups found in badcaps, I was not successful. Does anyone have some proven endorsements of this model that can facilitate me... Thank you

by jbonavitaHi, 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...theory/trouble...-
