Hi, i have a XPS1730

After connecting to power adapter, one led ( power sign ) on the right side lights up blue
but and after pressing power button, nothing happens, no led on keyboard no sounds, no fan's.
I know there is a problem with GPU, still it should start, but there will be nothing on the screen
I opened it and checked connections, everything seems fine
There is a led on disk drive that lights up after connecting to a power adapter, i checked ram's and took out battery.


I know this is an old laptop but it is very important for my friend and he want to fix it
Thanks for all replies
