Specs: Windows, Core i5/4gb ram
My laptop is working, I can hear sounds of windows but the screen is dead. I was just watching a video yesterday then the screen completely freezed then turned dead but the sound kept on going and i hear sounds of windows when i plug a usb device. Is this a motherboard and graphics card problem? If so, will it not work even if I buy an external monitor? Please share your thoughts!

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?).

An external monitor would probably work. You won't know for sure until you try one but any problem with the motherboard or video adapter would likely stop windows from booting.

Try the external monitor, borrow one if you have to in order to be sure. If it works, then the problem is probably with the monitor of a bad monitor cable. Both of these are repairable without breaking the bank, especially if you are handy with machines.

You have to be a little bit crazy to keep you from going insane.

Hello, thank you for replying! I bought a monitor yesterday but unfortunately it didn't worked either. Looks like it's in the motherboard or graphic card after all. My laptop is 4 years old by the way, and it's understandable if it gave up now especially with heavy usage like what I'm doing to it. How much do you think will cost me to repair it or is it better to buy new one?

This is the manual for your laptop:

There are sites selling the motherboard (and other parts too); this is the link to one listing the motherboard and other parts too:

In the region of US $225-230?

Thank you for your reply! Yes I tried the fn keys but to no avail. I think I will take it to a technician first to identify the specific problem. Then I'll start dissecting it like what the manual you post says. Thanks a lot, I think i might enjoy it too!
