My sony vaio screen got broken awhile back so I've been using an external monitor which was working just fine. My comp froze up so I turned it off manually and now monitor keeps going sleep and i have no way of seeing how to fix it. When i hooked the monitor to a desktop it worked just fine. I believe it is the vga port but im not sure on how to fix this problem. Any advice would be great.
 
look at your laptp user guild try doing a hard cmos reset. if it wont reset you may have a system board failure or a hard drive failure that causing the laptop not to post. try reseating the ram and removing the hard drive see if the sony logo shows up.
