If we spent a few thousand dollars to buy a
Apple laptop,
but do not know what the reason that laptop strike, how to do? If it is
possible to determine the initial power problems, you can more
accurately determine the power through the following methods where the
problem?
1. Check the
Apple A1374 AC adapter indicator
light, if the indicator light, generally think there is no problem from
the power to the Apple A1374 adapter, you must ensure that the light
itself is not damaged.
2. Check whether the
Apple A1374 power adapter
to the computer is power.This can be indicated by the notebook's
indicator light, when the Apple A1374 power is charged to the laptop,
that charging indicator light will be bright, otherwise it will not
light.or Find a same brand of power adapter exchange Try the same brand
of power adapter with your Apple A1374 power adapter laptop, if the
other computer is working properly, then your Apple A1374 power adapter
is no problem otherwise your power adapter may have problems if the
other side of the power adapter plugged into your computer, your
computer Working well, but using your own power adapter does not work,
then your power adapter has a problem.
3. Check the computer light changes. If you plug in the Apple A1374
power adapter, you can see the charging light sometimes bright sometimes
off, or always bright, it is the laptop inside the power adapter
interface problems, the general may Inside the line is broken, the
circuit board aging, welding drops and other reasons.This is called Weld
phenomenon.This situation only called experts to repair.
Take my Apple laptop as an example. The indicator of the
Apple A1374 power adapter is
normal, and when the power is plugged in, the computer can normally
spend about an hour, and then it will be powered off automatically. It
is observed that the indicator of the power adapter is on and the laptop
can sometimes Charge to power, sometimes can not charge.
Considered from two aspects, first, there is a problem with the
Apple A1374 AC adapter contact, sometimes power, and sometimes can not. I borrowed a similar brand of
AC adapter to
try and found the same phenomenon, and my Apple A1374 power is normal
in other laptops So ruled out the problem of the AC adapter
itself.Therefore, this is a problem of laptop.It was later found on the
laptop charging indicator flashes off, and sometimes has not flash,
causing the laptop due to not charging, the battery runs out and
Automatically shut down. This flash off a note here laptop interface is
not good, there may be broken. Later, sent to the Apple repair shop to
check, it really is a problem with the laptop power interface.
