Q:The laptop will automatically turn off the power adapter when the workload is large
Power adapter self-protection, more than power range automatically power off,
Q:Laptop adapter why the computer power lights on the off?
Short circuit. Power on, indicating that the power adapter is no problem. A computer lights off, indicating that the motherboard short circuit, that is, the motherboard on the short circuit protection phenomenon, the computer motherboard is broken, it is recommended to go after the sale for the motherboard, the warranty period this thing should not have money.
Q:The laptop is powerless.
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!
Q:ASUS Laptop Power Adapter 19V 4.74A. Use a multimeter to measure how much no load.
No load generally will not exceed 19.3v, measured.
Q:HP laptop power adapter drip, can not charge, suspected to be bad.
I suggest you open the power adapter to see where it should be off the welding, contact is not on, welding just fine!
Q:Dell laptop power adapter plug in the power indicator light is connected to the computer on the off is how the matter
Of course, the most vulnerable is the power, will engage in as long as the split for the two 1000U filter capacitor can be.
Q:Notebook off, plug in the power adapter okay? Does this laptop charge?
I do this every day, this is really the charge of the notebook. But it is best not always stuck.
Q:DELL laptop power adapter in the use of smoke suddenly out of the water, is this how is this going on?
DELL1420 notebook computer in use, the power adapter suddenly smoke issued Chi Chi sound, the adapter assembly cracks out of a little light yellow water; I immediately unplug the power, open the adapter, see a small amount of water out there, I would like to ask What's the matter? I am the adapter is 90 watts, from the purchase to now more than two years now, today is plug in the power ...
Q:I have an external monitor with a watertop unplugged the power adapter
VGA cable is easy to be disturbed, it is recommended that the adapter and the VGA line away a little. Or you have other interfaces, then use DVI or HDMI. Do not change your power adapter
Q:Laptop power adapter, the original 19v 3.95A can be replaced by 19V 3.42A it?
According to experience: 19 * 3.95 = 75W 19 * 3.42 = 65W The output voltage of these two adapters, so the computer light load (that is, the power consumption of the computer is not too large) is the case can be universal. The difference is that they can provide the maximum power is not the same, a maximum output to 3.95A current, one can output to 3.42A. In fact, 3.95A, 3.42A, are its nominal current, in fact, their Tolerance is 20% to 20% will be top of their OCP (overcurrent) protection. In other words, 3.95A may output to 3.95 * (1 + 20%) A, 3.42A the same. But in the case of heavy load, 65W may be the first to the top of the protection point, which occurred protection. Similarly, 65W heat is also higher. There are many protective mechanisms for the notebook, so there is no important work that can be generic. Motherboard itself has over-temperature protection, over-current protection, automatic frequency protection. The adapter itself also has overcurrent protection, over temperature protection, low voltage protection. In summary, can be common. However, it is best to use the battery together. If the supply of 65W is insufficient, there will not be a forced power off. In case of underfill, you will see that the charging lights on your computer are flashing, and you can unplug the adapter, re-insert it, and use it. Rated current is not enough, if the latter quality is good, it is estimated that can be used, but the fever is high and easy to damage, temporary emergency can, but long-term use or recommended current equal to or greater than the original current adapter as well.
