Hi, I have a problem with my computer…(HP Pavilion Laptop)?
When I turn it on the lights at the top light up but nothing shows on the screen. I took it to a technician and after opening it and checking the back of the screen he told me he didn´t know what was wrong with it although he though it could be the screen that is broken or possibly the graphics card, either of which would cost a lot of money to repair and possibly not worth the hassle. Before the screen stopped working I would occasionally see a thick yellow line down the right hand side of the screen but that hadn´t happened for a while. Any ideas what the problem could be and also do I have any right to contact Hewlett Packard with these problems as it isn´t even 2 years old yet (unfortunately I can´t find the receipt but can provide all the numbers of the computer from the underneath part - would this show that I only bought it 18 months ago?). Many Thanks for any advice.
1. Does it make the usual sounds as it starts up (beeps, whirring of the drives as they spin up)?
2. Does it run hot when left on for a bit?
If it does and you have no password on your account, connect it to an external monitor and let it start up (leave it for the time it would usual take for it to start). Then try switching to external monitor (Fn + one of the function keys, depends on the type which one exactly). If the monitor lights up only the screen is done for. If it doesn’t, it might be the mainboard, memory, processor, the graphics card or power supply.
Try starting it with battery only and with the external power supply.
Contact HP and tell them about your situation. The lack of receipts does make it easier for them to wiggle out of any service they should provide, but you do have a chance of running into a helpful tech, who will advise you.
