- Q: 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
- 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.
- Q: My notebook is Toshiba, the original adapter is 19V 3.95A, on the school forgot to take home, and then my mother to the outside of the shop borrowed a 19V 4.74A, the output current of 0.79 amps, I On Saturday with a few hours a week do not have to go to school at night to stay, may I ask this will be affected? I said that as long as the voltage on the Internet that does not matter, and some say that the current will burn the main screen too much, in the end? Put away
- The best notebook with the original, my Lenovo notebook only support the original, so you still do not use as well, in case of any problems on the trouble
- Q: My Lenovo power adapter is broken, can not charge the power, you can change it? Only to buy half a year, if you want to have a how much money?
- Dear Lenovo users Hello, if you want to buy power adapter, you can directly to the Lenovo service station to buy machine parts products, the specific price and other related matters, you can directly with the Lenovo service station engineers
- Q: What is the reason why the notebook's power adapter is not powered up
- If not, you can confirm the problem in the adapter or motherboard.
- Q: Samsung laptop power adapter bad how to do it
- There are hundreds of original, compatible, dozens, with their own wishes to engage in a friends.
- Q: Laptop power adapter squeak how to do
- First of all, to know is that the power supply to the books and the battery power supply to the notebook is different. Battery-powered, the battery output is pure DC, very clean, the battery voltage is neither possible nor need to design a high, lithium battery chemical properties determine a cell output voltage can only be about 3.6V, so Many batteries are used in three cascade way, 10.8V also became a very popular battery voltage. Some batteries are slightly larger than the integer value of 3.6V, such as 3.7V or 11.2V, etc., in fact, to protect the battery. Power supply, the situation is more complex, first of all need to add voltage to further regulation filter to ensure that the power performance is not very good in the case of stable work, the voltage regulator after the two parts of the city, all the way to the work of the power supply , The other way to the battery charge to the part of the power supply to the battery when the same power supply, and the part of the battery charge through the battery charge control circuit can be added to the battery, the control circuit can be very complex, so the power The voltage must be greater than the cell voltage to have sufficient capacity to supply the charge control circuit to the units. Finally the voltage actually added to the cell will never be the nominal voltage of your power supply. Rest assured. Hope that the above information is useful to you
- Q: (My power adapter line was broken by me, i want to buy a new one but do not know how to choose)
- The choice of the power adapter is not related to the type of notebook computer, as long as the output voltage of the power adapter V current A and the computer on the bottom of the nameplate marked on the input parameters can be consistent. It is best not to exceed 10%.
- Q: Laptop power adapter even the computer line off, then pick up can not be used?
- 1. From the 220V plug to the adapter cable. 2. From the computer plug to the adapter cable. If the situation is 1, with solder will be broken on the welding, wrapped with insulating tape. If it is the case 2, after welding, with a multimeter look at the computer that plug, outside the negative is not right, then you have to re-welding! This can not be wrong! Finally, do not forget to severely punish your home dog, of course, if you are reluctant, hungry it two good! Do not be afraid, absolutely bad not, you have to break the place to cut off, re-connected, but also on the line short point! Remember to wrap with insulating tape on the line!
- Q: Ordinary notebook adapter and one machine computer adapter can be universal?
- Appearance and output power are almost the case, let the practice test all of a sudden chanting.
- Q: Apple laptop power adapter bad how to do it
- Fourth, the optional power adapter In the maintenance process, because the current power adapter has been a large number of patch components, once the components out of the problem, the difficulty of maintenance even greater. Power adapter power is also increasing day by day, so the test of electronic components is growing, if the power adapter using the quality of electronic components, however, PCB wiring improper, it is likely to increase the probability of failure. Therefore, the purchase of a good quality power adapter, the stability of the notebook is very helpful.
