the 8 MB bios you sent also a 16MB one...you combined the 8MB bios...
The bios chip must be unsoldered from the board before writing or reading..
do not use the clip, you may have errors..if you do not have anything to unsolder it with,
solder wires between the programmer and the bios chip..

you need an SPI programmer...here is a video for example..https://www.youtube.com/watch?v=DWWi...nnel=ThisIsHow

thank you for your support. I use RT809H programmer. i desolder and solder for bios read and write. your bios write was successfull but the computer had the same issue.
power button keeps blinking. it seems something else.

Hi i have a NB6837C_MB_V3 motherboard from a Lenovo (all voltages are ok..no shorts , cpu working) ,,,
these are the dumps of 16m and 8m eeproms.

can anyone made a working bios (just to exclude the BIOS as a cause of black screen)

Type the laptop serial number, full name and model, motherboard model, etc.
read the forum rules..https://www.badcaps.net/forum/troubl...before-posting

[Assembler]

hi the motehrboard model is NB6837C_MB_V3 (as written on post)
there are no stickers on the bottom cover... looking at the laptop visually it's look like a reversible ideapad 2 in 1 .. 14" ... and this topic semes related to an ideapad 2 1 14" with this motherboard. (i've no serial.. can be extracted from EC-BIOS dump?) . the customer don't have anymore the external shipping box.

i will check more infos about the correct model.

your sn YX0BWCC0
next time check the length of the files. both are longer.
if you use xgecu you see there is a post here. don't save default, flash must be checked and save.

[Assembler]

Wow, very thank you! yes i'm using the TL8660II+ .. i will search for the topic about the lenght

[Assembler]

tried the BIOS. but no changes... like other users i have just the blinking red light (when battery is unpluged) .. the laptop is doing 3 restarts with 0.074 A at power on press... and after taht at something like 0.054 to 0.042 ... 3 restart and shutdown. with the battery the red light is not blinking stay white and after a while it just shutdown. damn!

ther serial point to IdeaPad 5 2-in-1 14IRH9 - Type 83KX

[Assembler]

bios from lenovo site:< ( IdeaPad 5 2-in-1 14IRH9 - Type 83KX)

[Assembler]

sorry boring again on this thread... i send messages to other users experiencing the same issue without any reply...
checked everything on the board ... switchings... magnetic sensor.. voltages.. everyhting seems ok...
the chipset is powered, the EC is powerred.. 3.3v and 5v are ok.. 1.8V is ok... no shorts... no burned things.. the 3.3 LDO is present...
pressing power button there is activity (3 restarts) .. but after a while the current consumtion become 0.043A... and nothing changes.

anyone has a dump of the 2 eeprom ( from another laptop?) for me looks like a bios/EC issue.
