Solved nv53a61u powers up but screen is black

February 17, 2014 at 11:34:05
Specs: Windows 7, AMD Phenom ll-PC3-10600s
When I turn on laptop I hear the cooling fan & hard drive running then in a few seconds they both stop. The screen is black and there are no beep or blink codes. The machine won't power off when I attempt a hard shutdown. There's nothing to indicate that it's attempting to boot. I've removed the battery & hard drive individually as well as swapped them out with known good ones. Swapped out the ram in all combinations with the HDD & battery. I swapped out the motherboard, did all of the fore-mentioned swapping combos and got the same results. In my opinion the processor is the only thing left. Before I invest in a new processor I'd like another opinion. I think this may be a no-brainer but want confirmation.
Also, nothing on external monitor. That's why I eliminated the screen early on. Thanks in advance for your assistance.

✔ Best Answer
If you aren't getting anything on both screens, it's always a possibility it's the graphics card. Have you tried swapping the current one out with another, or if it's onboard then putting in a new one?

Not sure where the graphics card is located on this machine without researching a manual for it, but I assume it's on the mobo and I've already replaced the that with a new one. Would a bad graphics card cause the hdd to stop spinning? Just before I checked back on this post I ordered a new cpu from Ebay for $14. Small investment.
I've tried starting with and without hdd installed.

If it is the cpu, would that explain why it doesn't post or boot to bios (which I forgot to add to original message) therefore info doesn't reach the graphics card/chip?

Hard to be certain but the PSU is another possibility.

Always pop back and let us know the outcome - thanks

Hope you aren't buying all those parts. If you swapped out the motherboard then you had to pull the CPU. Did you clean all the thermal compound off the CPU and the heat sink then apply new according to specs for your CPU?

try removing your battery and power cord holding down power button for 60 seconds the after that replace battery and power cord see if it powers back up many times this happens and by doing this it will fix the problem.this called going a hard reset

Sometimes known as "Flea Power" - see Google. It can help at times when things get stuck, particularly when you get a failure after some sort of update or when a program install fails.

Do you often buy things from Ebay for $14? If so, there is a good chance it is power supply, as cheaping out on this can be very bad.

Definitely try another power cord/battery and see what it does then.

Having bad RAM/CPU would cause the hard drive not to start, as BIOS wouldn't be able to load, and BIOS is what causes the hard drive to start. But no, a bad graphics card would not cause for BIOS not to load.
