It always wasnt like this, but now i need the charger to turn my laptop. should i get a new battery or is it my laptop itself, or the charger?
Look in your computer's system tray, which is in the far bottom right-hand corner of your screen, where the clock is. You should see a battery icon. If it doesn't show up automatically, click the arrows on the left-hand side of the system tray, which will expand the tray and show all icons.
A battery with 8 percent of its life remaining--low enough that there's a red

Place your mouse over the battery icon, but don't click. The icon itself will show roughly how much life is in the battery (half full, three-quarters full), but hovering your mouse over it will pop up a label showing exactly how much life remains in your battery.
Go to the Control Panel if there is no icon in the system tray, or you want more detailed information on the battery. Click "Power Options" and then the "Power Meter" tab. Click the battery icon for detailed information on the battery. The "Power Meter" tab will show the same information as the system tray icon; the detailed information tells you what kind of battery it is, as well as whether it is currently charging (plugged in) or discharging.
Plug in your AC adapter if the battery needs to be charged. The status in either the control panel or system tray will show that the computer is now running on AC power, and the battery is charging.
It sounds like the battery to me. That happened to my parents laptop. It wasn't too long after that though that it stopped turning on completely. If I was you I would look into getting a new battery or even a new laptop. they say that you might as well buy a whole new laptop instead of a new battery. The very least would be to make sure you back up everything on disk or even a flash drive so you don't lose anything you want to keep if the worst does happen.
this problem usually arises when you overcharge your battery all the time ..like when u sleep ,u leave the laptop running on electricity or even if the battery is full you keep on charging and do not remove the plug...so replacing battery/laptop totally depends upon your budget but make sure next time when you buy a new battery/laptop ,charge it smartly ...best option is -charge up to 90%,remove charger for half an hour again charge for 15 mins and so on...
Just replacing the battery should do, unless there's something wrong with the laptop.....
