So it allow charge .but pushing the power button doesn't turn the computer on or off.which means I don't know how to work on the lap top.so it has been a month with such problem.best buy said they can't fix it .if they had such issues they ship it to hp.i asked them should I buy new mother board where honestly I don't know how to replace the motherboard.i opened it googled it.its like may be the wires inside got disconnected where pushing the power button has no effect.
