Hello Everyone,

Make : Lenovo
Model: Slim 7 16IAH7
S/N: YX04XNTW
Mfg: 2022/09/13

System will not boot. I have tried the normal troubleshooting (external display, unplugged batter for 24hrs, holding the Novo button, tried to boot from usb using every typed of bootable media) i cannot get a display but keyboard backlight lights up but it's not responsive, fans spin and power button flashes but stops. After researching my symptoms, I am leaning towards a bad bios.

I have identified what looks to be 2 bios chips on my motherboard, both winbond...

Hi everyone,

I'm dealing with an intermittent problem and can't find a solution. Sometimes my notebook starts up and everything works fine. However, after I turn it off and try to turn it on again, the motherboard starts, but the screen stays black. It seems like the notebook freezes and a green LED with a light bulb icon stays on.

If anyone has the service manual or any suggestions on how to fix this issue, I would greatly appreciate it.

Thanks in advance!
