(Weird) BIOS info for HP Pavilion Aero 13-be1021AU

[Loki_Fido]

Hi folks,

This HP Pavilion Aero 13-be1021AU came to me for a repair. And it seems to have a weird BIOS chip. (Pic attached)
I asked my CH341A to read it and doesn't even know what to do with this. We are both very confused.

BIOS - XMC 25RU128CH10 (1.8v)

What the heck is this? I looked all over the MB. This is the only bios.
When I asked the NeoProgrammer to detect it, it just pops up an empty screen, and asked me to enter the bios number. And when I did, it doesn't do anything. NeoProgrammer showed me just this SPI ID: 204418. Don't know what it means.
I even googled it. No results.

Weird, right?
Is there a way to detect and read this chip? Anyone knows?


Any help is appreciated.

Hi peste,

Its not even getting detected. Then how to programming manually?

I googled the chip. No results. There's nothing about this bios in the internet.

I tried Neoprogrammer. AsProgrammer, XgPro and nothing.

HP threw a curve ball at me and it seems like i took it to me face.

you have to power it at 1.8v..not 3.3v...

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..

Hi peste,

I used the clip to attach it to the 1.8V adapter and then to the CH341a. Pics attached
Only received SPI ID: 20441.

Then I skipped the 1.8v adapter and directly connected to the CH341a.
Same result.

Is it possible to take a BIOS chip from another make/model motherboard and solder it here and download bios from HP website and write it into this bios, the system would be ok?

remove the chip from the board and stick it on the adapter where the clip comes from...and see if it detects it..

Hey peste,

Just did as you said. No difference.
Same result as before.

Im guessing at this point we just have to replace the BBIOOS chip. What do you think?

I just found this exact BIOS chip in Lenovo Yoga 6.
And i couldnt read that too.

Any idea why?

Is there something wrong with my CH341A? or its driver software?
