The cost to replace the cells is not economical as our company has looked into this. OVer time even a battery that has not been used that offten will stop holding a charge. Cost for a replacement battery online is about $125-$150. You maybe able to find one cheaper on ebay but be careful as some of them don't work for very long and have very limited warranty.

My hp pavilion dv6700t laptop is working fine when i connect it in charging, but it gives battery backup time only 10-15 minutes when i unplug power.

Ifthe laptop battery is more than 3 - 4 years old then the battery could be wornout. Rechargeable batteries have a finite number of charge and discharge cyclesand will lose their charge capacity over time, i.e. won't charge to 100% andgradually the charge reduces until the battery won't charge up atall. ORThe battery shows a 100% charge but when the adapter is disconnected thebattery drops off to zero capacity in a very short time.If the battery drops to an unacceptable chargelevel then the battery needs to be replaced.

Hi there!! I want to know is it a hardware issue or software issue.. When I pressed that ON button, the laptop start beeping for about 1.30mins and stop. Windows will come up after about 3-4 minutes....

Sounds like you need to use your backup, OR go to Start/ Help & Support/ System Restore, and have your PC go back to maybe yesterday, or to before you know this problem started. Something you did or a program did has messed with your system enough that it sure sounds like it isn't going to keep coming on at all soon. It isn't a hardware problem probably, just your Windows system. A hardware problem usually has lots worse symptoms. Give system restore a try! It works miracles. :) Always everyone should keep a backup of their system at least once a week. I hope if System Restore doesn't fix it for you, that you have a good backup. System Restore takes lots less time than a backup, though, so try that first, please.

My battery backup is only 10-20 minutes only,

I think what you are asking is why does your battery only last 10 - 20 minutes.
The answer is that you need a new battery. And here's a suggestion for you: When you install a new battery, let it run completely down 3 or 4 times to get it to accept a full charge. Thereafter, let it run down once a month to give the battery maximum life. Doesn't matter what the "experts" say--just do that.
Modern batteries are not supposed to have a "memory" but I've found that it's best to exercise a little preventive care.
Also--rechargeable batteries have a limited life.
