Sometimes I put mute on my Asus u52F and when I decide to turn mute off, my laptop wont make any sound...and it stays like that for a while, and suddenly the sound comes back.

If no one here helps you I would sugest asking Asus directly.

Sounds crazy but try removing the battery unplug from power hold power button for 15 seconds Then plug in and try to turn it on

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/larry_1fe25e09c54eece2

sounds like a bad driver download the best driver for it from their site.

Unplug from AC, remove battery, plug into AC , boot normally.

buy tv tuner card and you will be able to watch tv on your computer

Hi Icapelis...
Sorry...I did not come up with any service manual for your ASUS U52F-BBL5 anywhere on the net in my searches.
But I did came up with a youtube video of how to replace the lcd screen on an Asus U52f there is other videos showing how to disassemble other parts of the laptop.
Most laptops are disassembled about the same, just watch some of the videos and I am sure you will do fine. Just take your time and make sure you remember how to reassemble the laptop, write it down if necessary.
Always remove your battery before starting any repairs.
Sometimes the heating problem in laptop is dust buildup inside of the computer.
You might try to use some compressed air to blow out the dust of the laptop, You can use the kind in a can, but I perfer to use 90psi compressor air .
Just blow the air stream in the exaust first, then the intake,you will keep reversing the air flow untill all the dust is out of the computer.
Do not over spin the fan.
This may eliminate your heating problem.
Please take time to rate me

Sounds like a faulty wireless card or the card is installed with the wrong version driver.The wireless card itself sounds to be bad and needs replacing
