Here are some steps to diagnose your battery issue.
1. power down your laptop. disconnect/remove the battery and the charger.
2. reconnect the charger only without the battery. at this point, make sure the battery is not plug in.(we need
to make sure that your charger works fine).
3.power on the laptop with only the charger/ac adapter connected.(again, make sure the battery is not
connected).
note: if the laptop turns on without any problem.it means your charger works fine. it means that you've got
a known good ac adapter/charger. tried to charge your battery again, if nothing happens, it means your
battery is about to give up or it's already broken. contact your manufacturer to check your warranty.
Good luck,

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. Ifthe battery drops to an unacceptable charge level then the battery needs to bereplaced. Whenyou connect the power adapter into the laptop, does the power LED lightup? If not then - The battery adapter or the adapter's power lead or the laptop's powersocket could be faulty. Check power adapter's DCplug that connects into the laptop power socket with a multi-meter, the voltageshould be slightly higher than the voltage that is printed on the label on thebottom of the adapter. If the voltage is zero or way below the voltage that isprinted on the label then the power adapter is faulty and needs to be replaced. If the adapter is OK thenconnect it to the laptop and power it up, then look at the power/batterycharging LED light and wriggle the power plug in the laptop's powersocket. If the power/battery LED light flashes and in a certain position thisLED light stays firm, then the power socket is either faulty or it has a drysolder joint where it is connected to the motherboard. This can be repaired but itrequires the laptop to be completely dismantled to get at this power socket andrepair. If you cannot DIY then I suggest you get a quote first.
