Most likely the power jack socket has been damaged through some form of trauma or from old age.
The flashing LED indicates an interruption to the charging circuit and without AC mains power, the laptop battery is now fully discharged.
This is a hardware problem that requires repair by a computer shop.

How can you tell that the battery has 50% charge if the laptop won't power up?
Depending on the design of the power jack/power socket - at the very least the laptop will have to be disassembled in order to gain access to where the power socket is connected to the motherboard. Disassembling any laptop is not an easy task and should not be attempted without some element of experience as it is easy to damage the small components/cables while taking the unit apart.
Due to the complexity of this particular fault, if the laptop were sent for repair under warranty, the company would simply replace the entire motherboard (complete with power socket intact) because it is easier to replace the whole motherboard than to attempt to de-solder a component, remove it, then solder a new component back in its place.
If you were to attempt this repair you would require highly specialised tools, not least a special soldering kit - any slip-up at this point could destroy your motherboard for good.
I'd check with a local computer repair shop to get a quote for the repair at least. It could cost you more than the quoted price just to buy the required tools for the job. ;)

To turn on the computer, press the power button. When the computer is turned on, the power light is turned on.
If the computer and the power light are not turned on when you press the power button, adequate power may not be available to the computer.
The suggestions below may help you determine the reason the computer will not start up:
If the computer is plugged into an AC outlet, verify that the AC outlet is providing adequate power by plugging another electrical device into the outlet.
If the computer is running on battery power or is plugged into an external power source other than an AC outlet, plug the computer into an AC outlet using the AC adapter. Make sure the power cord and AC adapter connections are secure.
If the computer is running on battery power:
Remove the primary battery pack and travel battery pack (if applicable) and plug the computer into an AC outlet using the AC adapter. If the computer starts up, one of the battery packs may need to be replaced.
If the battery light on the front of the computer is blinking, the battery pack has reached a lowbattery condition, which may not allow the computer to start up. Plug the computer into an AC outlet using the AC adapter to start the computer and allow the battery to charge.
