Laptop is always asking for start up repair

Hi All,

I have a HP-dv6 1256 tx laptop which is 4 years old.

Whenever i start the lappy,it asks for start up repair and ultimately i have to load the OS.

Everytime i have to use the lappy,1st i hav to format and load the OS.

The lappy does not have a battery back up.

Kindly assist me , what i should do ?

Shall i put a new nattery or shall i take to the service centre or is there any other solution.

Is there any hardware replacement required??

Thanks,

Achyut
