Plug in not charging
There are several factors why this situation happens. It could be
improper use of the power adapter or because the battery is not being
cared correctly. On the other hand, exercising the performance of
battery sometimes by draining it completely before charging it again is
a good method of prolonging the battery life. If you noticed that the
battery is not charging, always check first the power outlet if it is
live or not before doing serious investigation.If the wall socket is not the cause of laptop battery charging failure, the following troubleshooting tips might help you.
1.
Check if the AC adapter is bad or not. Detach the battery from the
laptop and turn on the computer with the power plug connected. If the
laptop does not turn on, try using another power adapter to verify if
the first one is defective. If the second trial does not work as well,
the problem might be the power circuit of the motherboard. Look for a
certified computer technician to help you solve the issue.
2. If
the computer does turn on, the power adapter is in good condition and
not the cause the problem. In this case, try placing another battery
that meets the technical specifications of the laptop for proper
testing. If the second battery works well, it can be concluded that the
first one is defective.
3. Determine if the problem is not caused
by a software related issue. If the notebook battery status is not
being displayed correctly though software, it can be considered that
the software is causing the problem and not really the battery.
4.
Power reset the unit by unplugging it and removing the battery. After
doing that, hold the power button down for a minute. Then, attach the
battery and power adapter, and start the laptop again. This method is
being done to ensure that the motherboard is not holding power anymore
when the battery went down causing a "hiccup" in the system. This may
solve the charging failure of the battery.
5. If the battery
stops charging every time the charge indicator reaches 96-98%, the
laptop may need to be recalibrated for a new battery. For proper
notebook recalibration, the Windows power management should be
configured to prevent the system from going into sleep mode or
hibernation when the battery reaches the low level. For Windows XP
users, navigate to Control Panel > Performance and Maintenance >
Power Options. Set "Power Schemes" to "Always On". Under "Alarms",
uncheck "Low battery alarm" and "Critical battery alarm". Under
"Hibernate", uncheck "Enable hibernation", and then click on Apply.
Doing this procedure, the laptop battery can now be drained fully until
the computer system shuts off. Then, put the adapter back into the
power jack and let it charge completely. Sometimes the cycle must be
repeated 2-3 times before it actually reaches the 100% full charge. The
charging process should last at least around 14 hours.
