service tag is JUST JDVD1Z2 ...

1st boot press F2 and write service tag, disable Absolute, Apply Changes, restart. 2nd boot press alt+F to exit factory mode. Let it run for 2mins, it will restart several times without displaying anything.

Cu placere!

try..

ty for the quick reply. dunno if bios is soldered bad, but laptop didnt power on. dunno if bios problem or solder problem or something else has happened. maybe ill try resolder the bios again and see if it start.
for now thank you very much.

edit: i check bios solder and all looks ok. maybe i could try with original bios back ?
edit2: i ll wait maybe some other file to try, as my adapter is cheap and smells terrible when soldering the bios on it, also if it work i dont have to take board in and aout too often as that notebooks looks like it can brake any moment

write above bios original ( not bios replate )

ok, sorry for the noob question, this is the first time doing that. so i need to program again bios chip with my original backup, then instead of doing erase, blanc checking, write and veryfy i just need to write without erase, blanc and verify ?

tnx very much for the help.

update. after last bios flash with peste bios, laptop was dead (no more power on), so i put original bios back and without erasing eprom i put your bios on it, with same dead laptop as result. thinking i may have damaged the notebook and in addition my bios adapter was a chinese crap quality that smell like burn plastic i put the laptop aside for a while. today i got new adapter and flashed your bios with normal programming(erase blanc checking write, verify) and after reassembly it it started and all is working perfectly.

big tnx to both of u for helping.
my question is .... was peste bios not ok, or maybe bios soldering was not at first ?

again big tnx im more happy that laptop is still working other then remove the password in oit. ( ofc password is gone now and i can format it.)
