Sony Vaio VPCSE29FJ

[kodox]

Someone could verify this dump is ok or not and if not please fix it since i don't have the tool (especially brain) to do it...

The problem with this laptop is, it powered on but less then a minute it shut down by itself and it will "auto shutdown" again when turned back on again

thank's...

Re: Sony Vaio VPCSE29FJ

Bios .

flashed it to bios chip but no respon on power button press, but all power rail activated after pressing power button for the first time but not for the second time, i had to unplug adaptor first to get those power rail active & measured.

with original bios (attached on first post) this laptop turned on and had display on the screen before "auto shutdown".

i was compared dump file attached on first post and the file from @SMDFlea using Hex Editor, it has small difference at the end (picture attached). before i flashed file from @SMDFlea i try to "read" again content on the chip and i compared against first dump file i've uploaded here and suprisingly Hex Editor said it perfect match 100% and as expected the file length is the same but, different lengthe (shorter) when compared with file from @SMDFlea. is this could lead the problem? if does, where could be the culprit? the programmer i'm using (CH341A) or the software or perhaps the bios chip?

help would be appreciated, thank's....

Its your programmer that added the extra 4 lines.Try another bios chip and use AsProgrammer software https://www.badcaps.net/forum/showpo...6&postcount=10

tried flash the chip using AsProgrammer with worst result, after pressing power button only 3valw, 5valw, 5valw_ldo & ecvcc (3.2v) power rails activated. 3vrun that power the bios chip isn't activated too, any ideas where to look?
