Acer old section of the laptop, before the emergence of insufficient power supply symptoms (presumably: maybe and I will be the original 120g hard drive for 500g).
Yesterday in the normal circumstances, suddenly on the power. The power of the laptop power indicator is no longer bright, neither power. Details are as follows:
1. With the battery can be normal boot, the normal use.
2. The power adapter has been removed and the adapter is ok.
3. Connect the power, no power, but the machine will be issued a slight, rhythm, 'drop - drop - drop' sound.
Here to ask you, where the problem may arise, the motherboard power supply part, power supply capacitor? The
If this is the case, take the repair, then, is the need for a whole board, or for specific components on the line.
How much is the price expected?
Hope expert answer, reward points is not a problem.
Thanked here
Do not use the battery battery to take the power to try
For the motherboard is very expensive ah
Repair the motherboard ah
We specialize in notebook motherboards
Should be the motherboard power supply circuit problems, but the possibility of capacitance is 0, as for the repair is for the change or for the motherboard to see the professionalism and the level of the repair, and good professional ethics, the level of high certainly for the specific parts, so You spend less, and vice versa for more trouble ah! Anyway, you pay, technical staff save trouble on the line!
1, power adapter failure, replace the power adapter. 2, whether the outlet power. Replace the socket or card. 3, the computer power interface failure, the problem lies in the motherboard, need to open the body to check to judge. 4, remove the battery only after the power to observe the machine is normal. If not, you can confirm the problem in the adapter or motherboard.
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. After releasing the notebook residual charge, insert the power adapter separately, power on the test.
4, if the fault remains the same, check the notebook's power interface, whether abnormal. Such as loose or the appearance of damage and so on.
5, the above check are normal, basically can be a preliminary judgment is the notebook motherboard failure. Recommended repair service station.
