If there is a electrical multimeter measuring charge under the head first

1, check the battery, to see if the line appeared loose, not firm connection problem,
2, if the line is normal, see if the battery charger circuit board is broken, change a try,
3, if the line is normal, the charger is good, it could be computer internal circuit board failure,
4, battery for three years or so commonly, basic aging, even the lithium battery, can go to a repair shop testing,
5, batteries commonly used by about 20%, you need to recharge, don't wait to be 0, recharging, too hurt the battery,
