|Basic I know, |
I note you say it doesn't work with an external display... Have you double checked the Function key display options?
If per chance the graphic card is a plugin module then it may be worth to pursure a replacement module, and (if you're happy to take the case apart - to some degree) replace the duff module yourself.
If it's glued to (i.e. soldered onto) the main board then a replacement board plus labour may start to approximate the cost of a new laptop? Disassembling many laptops is a time and patience event; and does require one to have the correct mini screwdrivers too (readily available "out there" nowadays).
The service manual for your model may well be online too, and that will detail how to strip it down and replace parts various - where applicable (although many are reasonably obvious as to how to remove the main bottom cover assembly).
If you opt for a new laptop then this one will still serve nicely as a desktop sorts, and of course is networkable and a useful spare/reserve unit etc in emergencies (if per chance you can get the external display to work at least?).
