Installation guidance
The replacement is straightforward for any technician with basic laptop disassembly experience. A walkthrough:
- Identify the existing BIOS chip on the motherboard — most are SOIC-8 marked W25Q or MX25.
- Read the original BIOS using a CH341A programmer with SOIC-8 clip before removing it.
- Desolder the old chip using hot-air rework at 350°C, lifting straight up.
- Clean the pads with flux and isopropyl alcohol.
- Pre-program the new chip in a ZIF socket on the CH341A using the dumped BIOS file.
- Solder the programmed chip back onto the motherboard, verify pin-1 orientation with the dot mark.
- Power on the laptop and confirm BIOS POST. If it stalls, re-read and re-flash.
