Hi, I´m trying to program the IT8227E with a RT809H programmer on a Lenovo board NM-B931.
I´ve set up the lines according to the schematics and connection is made with a 24pin flat-cable. (see pictures).
Unfortunately I get a error message when I try to read this chip. I´m curious if this chip is really not programmable via the keyboard connector. If I measure with my multimeter I get a connection between the EC and the pins on the KB-connector...
Can anybody help?Attached FilesPremium supporters get full download access and other benefits.

Model: Lenovo Yoga Slim 7 15ILL9
Machine Type Model: 83HM
Motherboard ID: LNVNB161216
TLDR: I would like to have the clean BIOS dump file for my laptop model.
Issue: First, my speaker wasn't working/showing up, so I downloaded the recommended BIOS update (from Jan 4, 2026) on Lenovo Support for my laptop. This didn't fix the speaker issue after restarting, so then I shut it down and pressed the power button for 60 seconds to perform a reset. I'm guessing I somehow messed up the BIOS because now the laptop won't turn on even after trying the NOVO button on... -
Hello everyone,
I’m hoping someone can help me locate a verified original BIOS dump for my Acer laptop.
This is NOT a BIOS password removal request.
I’m looking for an original 32MB SPI BIOS dump to use as a reference in case my BIOS firmware is corrupted. My plan is to first dump and back up my own BIOS as soon as my programmer arrives. I am not planning to blindly flash someone else’s BIOS.
Laptop Information- Model: Acer Predator Triton 16 PT16-51-99GL
- Motherboard: DA0ZQDMB8AE Rev. E
- Main SPI flash: Winbond W25Q256JVEN (32MB)

Hi everyone,
I've got a Lenovo Legion T5 26AMR5 (MTM 90RB001LUS, SN MJ0FTYZZ) on the bench that's giving me a bit of a headache.
The machine powers on normally. All fans spin, RGB comes on, and everything looks like it's starting up, but there's no display and no POST. It just sits there powered on.
So far I've swapped in known-good:- CPU
- GPU
- RAM
- PSU
The behavior is exactly the same with every combination.
I've also:- Cleared the CMOS
- Tried one RAM stick at a time in different slots
- Tested multiple video outputs/GPUs
- Looked
