Hi guys,
Been trying to fix up this one for a while, but still a beginner on diagnosing. Hope you can bear with me on a potentially long-winded explanation, will to keep it brief.
Got this one as a fixer-upper, arrived with screen hinge busted, missing riser posts for cpu and gpu, and no lights on attaching ac adapter.
tried inspection, short detection but seemed like issue was in boot.
Measured and got these readings
+3VA = 3.3
+5VA = 5.00
PS_ON = 3.3
+3VA_EC = 3.3
EC_RST# = 3.23
3VDSW_ON =...

Asus Vivobook X580VD Rev 2.0 not powering on repair

Re: Asus Vivo Book X580VD BIOS Needed
i think i finally realized this past weekend I was following the wrong clue. wasn't getting 12V power rail so 3V for EC derived from 12V also was not working.
got fan spin from shorting the open circuit mosfet, so will replace them and continue. Thanks for the help with BIOS.... -
Re: Asus Vivo Book X580VD BIOS Needed
thank you so much. I saw that EC.bin contents embedded in the main bios .bin file at 00200000. So if using CH341A programmer just need to flash the main bios.bin, correct?
Will try, and report back....Leave a comment:

Re: Asus Vivo Book X580VD BIOS Needed
tried cleaning on my own but doesn't seem to have helped.
can anyone help me? also i don't understand if EC bin is included in the bios or is separately flashed. thanks in advance.Leave a comment:

Re: Asus Vivo Book X580VD BIOS Needed
I managed to get this dump of my bios chip but unsure how accurate.
Would someone be able to help transfer details to fresh bios for x580vd rev 2.0?
or if you point me to a tutorial on how to do it, i should be able to figure it out. tried fd44editor and it didn't work for this.
Thanks....Last edited by fwah23; 04-26-2022, 08:04 PM.Leave a comment:

Re: Asus Vivo Book X580VD BIOS Needed
thank you! I did check that power rails all the way to the EC are up and okay, so this is my best guess so far that it could be a bios issue. From your understanding, wouldn't the charging circuit also depend on the bios and EC to be non-corrupt to start working?
I guess I will try the CH341A programmer. I should do the 3.3V hack to do the flashing safely, correct? being cheap is hard work.

Re: Asus Vivo Book X580VD BIOS Needed
stumbled upon this thread as looking for a bios for my m580VD-DM689T, the inside sticker shows (205) X580VD. have a board that is not powering up, no lights, not charging. suspect it's the bios as the DPWRON_EC reading is low.
first time doing this, may I ask what programmer tool do I use to flash the BIOS? is the recommended way to remove the chip off the board or is there a way to do it with the bios chip still on the board? thank you in advance.Leave a comment:
