Hi Hoaca388,
I have checked the soldering of [B]25R256JWEQ [/B]and it seems to be ok.
What should I do with [B]W25Q128JNSQ [/B]?
Should I leave the original BIOS inside?
With the original BIOS the pc would not boot and would not charge.
When I used the [B]OF_W25Q128JW1.8V@SOIC8.BIN [/B]BIOS from Alegoff, the laptop could charge and it could power on but the ESC,F1, F4 lights were blinking.
Afterwards, I tried to flash other BIOS dumps to the same chip and from that point on, the Laptop could not be charged.
Even if I dump [B]OF_W25Q128JW1.8V@SOIC8.BIN[/B]...Leave a comment:

Hello Bios Cracker,
There is no charging light and the laptop can not be turned on....Leave a comment:

With this BIOS version, there is no charging light, and the laptop can not be turned on.
A bit of background from two days ago:
After flashing the EC BIOS from your second post (the "OF" version), the charging light turned on, and the ESC, F1, and F4 keys started blinking.
When I tried to power on the laptop, the power button's LED lit up, but there was no display output, and the blinking keys stopped.
After about two hours, the blinking stopped completely.
Since then the laptop has no charging light....Leave a comment:

Hello,
Thank you Alegoff for sharing your findings.
It seems I was trying to read the wrong chip.
The correct chip was: W25Q128JNSQ
I have tried to use your [I]OF_W25Q128JW1.8V@SOIC8.BIN[/I] file and the charging light turned on.
Afterwards the Escape, F1, F4 buttons were blinking continuously and the laptop could not be turned on.
I have attached the original W25Q128JNSQ dump in case anyone can help me since I do not know how to proceed.Hello,

The chip is: WINBOND [B]25R256JWEQ[/B]

Can i dump the BIOS with another way without desoldering the chip?Hello SMDflea,
