LG Gram z980, touchscreen option.

[TigerBest]

Sorry for my poor english. I hope you can understand what i say.

I'm trying to replace a LG GRAM z980's normal screen to a touchscreen. I use the original touchscreen panel of the touchscreen-edition of the laptop. According to my review, all editions of the laptop are using the same motherboard, just different in screen, ram and etc.

The touchscreen panel can display successful, but its touch function doesn't work. I got an HID I2C error code 10 in Windows Device Manager, it says the device cannot start.

I've tried all software way to fix it but never works. So I guess it might be a bios problem, maybe the bios detects my laptop is not a touchscreen edition, so it turns the touchscreen off.

So is there any possible to mod the bios to fix the problem?

Thank you so much.
