done, done, done
i am using "fc /b" cmd utility.
there are 3 bios dump in my bios.zip. they are identical. they are also non empty
i compared my bios dump with the manufacturer's one using fc /b found several differences
one youtube video taught me that manufacturer provides bios in a capsule and we have to extract it using uefi tool.
i did that.
i also tried to read with uefi tool, my bios dump, it seems readable and similar to manufacturer's bios. but only in the bios section, so i cannot know for sure
is my manufacturer...

how would i go about that?, mind you i am just starting to learn laptop repair.
i could not find schematic or boardviews for my board, how to find 5v lines.?
it may be significant to point out that i never had usb port problems. sometimes i did find out that my cables were faulty.
i think( correct me if i am wrong) we should focus on flashing bios.
if this doesnot work then i'll check for partial shorts. cuz i do not even know where to begin.
thank you for replying..
could you please check my biosdump- if the read was ok!...Leave a comment:

I tried the WinFlash method, it failed. the BIOS still does not open. but while updating with Winflash, it looked it everything went smoothly. ez flash utility automatically opened.
but alas, no success.

Thank you so much for taking the time.
i too think that.
Today i tried to put everything (disassembled) back together.
it magically booted to windwos.
It still has issues booting to bios.
its probably corrupt.
I will try to dump my bios.
And flash it maybe
is using a usb flash better or a external programmer?

lenovo flex 5 14itl05 power sequence issue
hi guys, my motherboard will not start no matter what
when connected to ac power, the battery does get charge, led indicator glows red when discharged and turns white as it is fully charged.
but rest nothing happens no sign of life.
this laptop has one preexisting usbc power issue - so i use DCIN jack for charging my laptop.
with this issue my laptop was unable to power ON only sometimes i just had to wait some time.
but now nothing happens no matter how much i wait/ charge/ press and hold power button.
i have no knowledge of motherboards .... -
my bad R1 is a fuse, kind off.Leave a comment:

no, i was working on metal plate, and there was some movement and the live wire touched the plate and near the soldered joint and back plate of LED (heatsink) made a connection. i think.
R1, R2, L1, and the first LED(only) was blown(open) so i replaced them all only for them be blown again (this time i made sure everything was insulated) maybe something else is shorted too. hope its not the IC.
Can i not use this LED circuit without input filtering. if i am unable to find the right parts....Leave a comment:
