This could be the battery. Batteries are funny some last longer than others and some don't last long at all. This could also be the power management chip on the motherboard. This chip controls and regulates the power, it also allows the machine to switch back and forth from battery to AC, and controls the charging system. I'm leaning towards the chip, because a bad battery shouldn't cause a shut down when the charge is complete. I suggest you take it in for a professional diagnostic. They'll be able to check the power management system and tell you exactly where the problem is, and if it's a replaceable component.

WHEN I HAVE MY LAPTOP PLUGGED IN IT CHARGES BATTERY TO 40% THEN STOPS WHY'S THIS


Hi Tina,

Your battery needs a calibration, follow the instruction below to calibrate the battery.

  1. With Windows Vista, navigate to Control Panel > Performance and Maintenance > Power Options
  2. Click "Change Plan Settings".
  3. Set all tabs to "Never" underneath "On Battery" column.
  4. Click "Change advanced power settings".
  5. Set Sleep > Hibernate after to 0 or Never.
  6. Set Battery > Critical Battery Level to 0.
  7. Click on "OK", then "Save Changes".

This is the only time that we recommend taking the battery all the way down to zero percent. Unplug the ac adapter, and let the battery drain all the way down until the laptop shuts off. Then plug the AC adapter back in, and let it recharge to 100% or where it actually reaches. You may need to repeat the cycle 2-3 times before it actually reaches 100%.

Note: After the calibration is done, change the power options settings back to what it was as they will help you save power. Also, when a power source is available dont run the laptop on battery, it will increase the battery life.

Regards,
Shrey

Whenyou connect the power adapter into the laptop, does the power LED light up? Ifnot then - The battery adapter or the adapter's power lead or the laptop's powersocket could be faulty. Check power adapter's DCplug that connects into the laptop power socket with a multi-meter, the voltageshould be slightly higher than the voltage that is printed on the label on thebottom of the adapter. If the voltage is zero or way below the voltage that isprinted on the label then the power adapter is faulty and needs to be replaced. If the adapter is OK thenconnect it to the laptop and power it up, then look at the power/batterycharging LED light and wriggle the power plug in the laptop's power socket.If the power/battery LED light flashes and in a certain position this LED lightstays firm, then the power socket is either faulty or it has a dry solder jointwhere it is connected to the motherboard. This can be repaired but itrequires the laptop to be completely dismantled to get at this power socket andrepair. If you cannot DIY then I suggest you get a quote first.

The battery full charge only reach 98% & says pluged not charging!!!what this mean?


Due to regular use of the notebook, some static charges tend to stay in the computer, and sometimes results in not allowing the computer to function properly.

Please follow the power drain procedure to confirm the same:

1. Disconnect the AC Adapter.
2. Remove the Battery.
3. Hold the Power button down for 30seconds to 1 minute.
4. Put the Battery in.
5. Reconnect the AC adapter.
6. Turn on the Notebook power.
7. Restart the Notebook.

Battery indicator keeps fluctuating to 4hrs to 6hrs back to 4hrs then 8hrs every 5 mins or so i have acer A0532H with windows 7


first of all let me ask how old is the battery, if it`s new-discharge the battery until pc shuts down itself because of low battery, remove the battery , unplug AC charger from laptop, wait for 5 minutes, then hold power button for 5 full seconds, wait another 5 minutes, then put battery and ac charger on , don`t turn on laptop yet, wait until battery indicator shows that battery fully charged, then remove AC charger, and turn on laptop. P.S. you can try this on old battery too, but usually worthless, because old batteries are not recognizable by system currectly ..

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.

1. First remove the Battery, clean the Battery contacts with the pencil eraser and insert the Battery in the Computer.

2. Connect the AC Adapter (Battery charger) securely to the Computer and the Power outlet.

3. If the issue persists, try connecting the AC Adapter to different Power outlet.

4. Make sure that both the connecting points (DC IN port on the Computer and the Power outlet plug) are securely connected and not loose.

5. If the issue persists, try with different AC Adapter.


Good Luck!!!!!!!!!!!!!

New charger but no ac power to pc


A common problem is for the power jack connections on the system board to go bad. They break loose from the main board because the power plug gets flexed and then the power doesn't get from the adapter to the board. No power light (or intermittent flickering) and no battery charging results.

What you need to do (or have done) is to resolder the power jack onto the board. This isn't difficult, but it involves getting the main board out to reach the solder side. In some cases the board can be damaged because of the bad connections and isn't repairable. Then the board needs to be replaced. But most often the soldering fixes the trouble.
