[SOLVED] Asus k53sv won't boot after failed bios update. What do?

[ddzen]

So the previous bios version pre fail was 315 and the one i got from asus's page is v320 the direct successor. I saved it on a usb stick and followed the user manual instructions for that particular laptop, and the install was going as per normal until the screen went black and stayed that way until i shut it down after waiting 2+ hours. I haven't been able to start it up since then. Even when plugged in the leds are dead.

What I've already tried:

- to discharge the laptop by detaching the ac and taking out the battery then holding the power button for 15-20 secs.;

- opened the panel and reinserted the CMOS battery after waiting for it to cool 20+ mins;

- reinserted the hdd and ram sticks;

Is the mobo dead? Is there anything i can do to save this poor <Mod Edit>?

First, why were you updating the BIOS? BIOS updates are only needed when you are experiencing a problem directly addressed by that update. If the change list does not list your issue then an update is not required.

Second, it's very likely that the failed update bricked the board, which now requires replacement.

im aware the board is probably bricked im asking if there is anything out there that i can still try pls be useful instead of pointing out the obvious.

Bricked is bricked. Your only option is replacement. Don't know what else you want to hear.

the board is not bricked updating bios does not brick the MB it only corrupts the code inside the bios chip.
you need to get a bios chip programmer youtube how to do it.(laptop flash bios) put together idea how it works what you need.

you need to download the bios file from the manufacturer or google it for your model flash it that's it, you need to solder the bios chip of the MB.

the chip and ic you see on MB are programmed to do the individual task but you may ask how this is when you write code such as

Declare Function timeBeginPeriod Lib "winmm.dll" (ByVal uPeriod As Long) As Long

Declare Function timeEndPeriod Lib "winmm.dll" (ByVal uPeriod As Long) As Long

Declare Function timeGetTime Lib "winmm.dll" () As Long

If StrComp(Value1, value2, 1) = 0 Then

    IsEqual = True

Else

    IsEqual = False

End If

   Dim t1 As Byte, t2 As Byte

    Dim lSz As Long

    Dim i As Long


    IsEqualB = True


    lpS1 = StrPtr(Str1)

    lpS2 = StrPtr(Str2)

    DerefLong lpS1 - 4, lSz


    If lSz = LenB(Str2) Then

        For i = 0 To lSz - 1 Step 2

            DerefByte lpS1 + i, t1

            DerefByte lpS2 + i, t2

            If Not (t1 = t2) Then

                IsEqualB = False

                Exit For

            End If

        Next

    Else

        IsEqualB = False

    End If

it will have code like this programmed inside each chip.
they basically get overwritten when you flash a bios.bin file and if it fails to install then MB, will fail to load or boot because the half of the code that it tried to install on-chip is missing.

Thanks for your help! Im looking to order the necessary equipment atm but first i need to know if it 100% has to be the TL866CS programmer or can i use a cheaper one with a test clip like that one for example - https://www.amazon.com/Organizer-Socket-Adpter-Programmer-CH341A/dp/B07R5LPTYM

Also If the bios chip is dead i'll need to get a replacement and that will require soldering but otherwise do i really need to unsolder/solder the chip if i can use the test clip and stick it on the chip and do the fix procedure?

will work should do as long it can read and write data that is good.
follow youtube tuts how to do the reading and writing your mb is ok.
these are intense engineering people by mistake think mb is damaged when its not.

bios chip dead
if bios fails to write or read get a replacement and write and solder it on.

to flash a bios you need to de-solder it write then solder.
every chip has pin1 it has 1 white dot near it. match that with the chip also when soldering it back on. take picture before you take it out
