If your laptop appears to boot up and the hard disk LED flashes, then the problem is probably a back light fault. This can be a faulty inverter or a faulty CCFL lamp.

Appears that recovery disk #2 is bogus. U can try to get a new set from HP (fat chance!) or you can do a reload from a normal, retail OS disk.

Hello Most laptop or PCs, has a combination keyboard pressing keys, that invoque the restore routine. usually F11 or F10. others has DVD, check and see what you have of these two. in the first one, you recover from a disk partition the whole OS.

Its all about go to HP page, and bios updates, the instructions are there too! but be aware you have to be more specific on model, and BIOS dates.

You may have a virus, malware, adware, a browser hijacker, or pups (potentially unwanted programs). A. If your computer will boot and you can operate it ok... Download and install Malwarebytes and Superantispyware (Note: If you can\'t do the download on your machine, do it on a friend\'s, put them on a thumb drive, and install them from it). Then scan your computer with each program, and quarantine anything found. B. If your computer won\'t boot, or can\'t operate properly after boot... Tap F8 when you are booting, select "Safe Mode With Networking". Download and install Malwarebytes and Superantispyware (Note: If you can\'t do the download on your machine, do it on a friend\'s, put them on a thumb drive, and install them from it). Then scan your computer with each program, and quarantine anything found. C. If this process finds malware, to keep stuff like that from coming back, I recommend you get the paid version of Malwarebytes.Good luckG

If the fan making a smooth spin, but the noise is too loud, then it means the fan is trying to dissipate the heat. Probably the air inlet and or the air outlet (also the fan itself) is dirty (or clogged) and you need to clean it up using a canned air. You may need to open the case/body if the dust become a dust ball (and you need a tweezer and qtip to pickup the dust ball and clean up the fan blades).

Ask The People Who Work At HP To Find Out !

if u r listening extra vibration sound with actual sound just change speakers

try using a can of Air Duster on the bottom of CP57 where your fan is located to clean out the heatsink allowing your system to stay on and figure out the issue.
