Re: HP Omen 15-ax201ns bios dump

Hi

I have a question and it maybe helpfull for someone

Lets just say motherboard gets fixed and boots with virgin bios

will it ask for DMI and Keywin info at display or will not show display(post) without these information.

secondaly for info in bios bin file

DMI region found from offset 00222000-002220F0
and Keywin region at offset 00223000 -002230F0

i have updated both info in virgin file 08217 although these is something wrong with motherboard as no display even with virgin bios

Please correct me and share some thoughts thanks

write the bios chip only with the update sent ... in this case you should have inagine and the laptop to request your DMI information..bios better than the virgin one you will not find..if no image appears you have another problem .

As @peste has told you in this thread,and me in another,if it doesn`t boot with the virgin bios then the problem is somewhere else,trust us,or do you need a third opinion ?. Check the RAM,clean the gold contacts with an eraser,try some different RAM if you have some, and try with an external monitor/HDMI .If it still doesn`t boot i suggest you make a new thread in the main laptop forum and ask for help - https://www.badcaps.net/forum/forumdisplay.php?f=23
You will need a multimeter as members will ask you to take voltage readings and take the laptop apart.If you don`t have the tools or are not comfortable doing that take it to a repair shop.

Thanks for help, I have already mentioned above posts laptop did not boot with both bin files and both files were identical when compared with hex editor so it proves there is no bios chip issue and neither there is issue with memory RAM as already cleaned it with eraser tool , i think there is some issue with motherboard components like capacitors or Mosfets. anyways thanks for your help guys much appreciated.

If there is no voltage at BIOS pin 8 VCC

what are the possibilities

BIOS chip faulty?
