Hold down the ESC key while you turn on the laptop and then press F1 key.

Your OS is corrupted so you will need to repair or reinstall the os.

Try a system restore bringing computer back to a earlier time before this happened, this should restore the network settings.

problem in the hard drive
replace with solid state if disc operation

contact the dealer or manufacturer.
This is a frequent problem for portable harddisks.
Its a hardware problem,there's nothing much u can do.
u wont be charged if u are within the warranty period.

- The battery should fit snuggly. Have that checked.
- As for the sound problem, most likely, you have the "Hard drive protection utility" installed and enabled.

When you move the laptop, the hard drive protection kicks in and the read/write heads go into park position freezing the laptop for a fracture of second. Apparenlty this causing the sound to statter.

You can disable the hard drive protection for a while and see if it fixes the problem.

Also, try reducing the movement detection sensetivity in the hard drive protection utility.

One of two things is probably the case:

1. Your hard drive is missing and a new one will need to be installed.

2. Your hard is not missing, but it has become loose and either from its housing or where the housing connects to the laptop.

Please give a detailed description of the manufacturer and model of your laptop so someone may give you clear detailed instructions for how to check to see if you hard drive is either missing or if it has come loose somehow.
