msi ms-1543 gp66 leopard 11uh-684uk ms-15431 ver2.0 gpu issue- like driver error
the laptop has a wierd GPU problem
the GPU is there when you start the laptop and has the yellow exclamation mark in control panel
when you try to reinstall the GPU you install the driver and all OK
but when you restart same thing (the GPU is there when you start the laptop and has the yellow exclamation mark in control panel)
anyone has any idea
some are telling that the bios need to be downgraded
i did try to re-flow the GPU twice just to be sure but no change at all
so bios i think best option....??... -
acer predator helios 300 pt315-53-717r motherboard la-j891p rev:1b no image

asus UX-4100e Chip id help please X08Y 2176
Chip id help please
letters on the component as in pictures - IC X08Y 2176
the issue is with the main lcd backlight as iti is not getting power via the IC X08Y 2176 not sure what this is but must be kinda switching component for light as it is getting 15 volts in but not passing over ...... plan is to bridge in and out temporarily to allow for the customer to use both lcds after testing lcd not in short on the light side ......... -
hi i agree it looks like that
but i think this is down to connection as 2 new GPU i used and new set of gddr
i was thinking that it might be some capacitors .....filtersLeave a comment:
