1, with a multimeter to check whether the normal socket, the supply voltage is 220V. If the utility voltage is not normal, it is recommended to replace the use of environmental testing. 2, with a multimeter to check the power adapter output voltage and current is consistent with the label. If the gap is very large, and the mains voltage is normal, you can determine the power adapter failure, Need to replace the notebook power adapter. 3, if the above check is normal, remove the laptop battery, do not external adapter. Press and hold the notebook power button 5 seconds to repeat 3 times.

I'll answer you! Power adapter is a switching power supply, it is the first to rectify the AC rectifier, and then through the chip control power switch to a certain frequency of exchange for the exchange, and then through the transformer buck, and then rectified into a DC, the final output, I think the input DC should be no problem, you can use!

Q:Just want to know what courier from Taiwan to Shanghai.

Computer is able to use, that is, power to fit. If the adapter's input voltage is 110-220v or a wider range, you can use it directly. Otherwise you can buy in the mainland input 220v output and computer matching adapter.

Q:I am Acer's notebook, now with 2 oh minutes or so, it has been very hot. Just bought a few days. Before the five hours are not now hot, how is it?

Does the adapter heat up to the computer? Seek the solution

In the charging process, when the battery is saturated, the end of the charge, the adapter hot phenomenon has eased. Under normal use, the use of AC power, there will be hot phenomenon, if the air-conditioned room, the hot is not very obvious, in the non-air-conditioned room, and summer, hot phenomenon is obvious. ? The heat adapter parts and materials of the power adapter itself are not very good, long-term use, heat backlog, there will be hot phenomenon. In fact, power adapter hot is not a very serious problem, pay more attention to, if it is a quality problem that is timely replacement.
