How to do if your laptop “ plugged in but not charging”

How to do if your laptop “ plugged in but not charging”

Sometimes, you connect the AC adapter but getting any juice. What’s the matter and what is to be done about it?There are several reasons and how to solve the problem.

1. Replace the Battery

Remove the battery and then plug it in and try to power it on. That way, if it turns on, you know there's (at least temporarily) a good connection between motherboard and DC jack, the problem is likely a bum battery.

2. Examine the cord

Examine the entire length of the power cord for teras,dents,  and worn-down insulation. If you notice any, or if the power brick is warped or smells like burnt plastic, the cord is probably faulty. You'll need to purchase a new cord for your laptop.

3. Check the Connector

Inspect the connection. If the cord's attachment to your laptop wobbles or feels loose, there could be a problem with the connection. Unplug the cord, remove debris with a wooden toothpick, and remove heavy dust build-up with compressed air.

4.keep the computer cool down 

If your laptop battery feels very hot, excess heat could be interfering with the charging process. Turn off the computer for several minutes to cool down. If you haven't cleaned your laptop vents recently, blow a can of compressed air into the fan vents, to remove some dust.

5. Check Your Settings

For Windows Laptops: 

Check your power settings. Go to Start → Control Panel → Power Options. There may be a "low battery level" setting at too high a level, which can cause your computer to shut down instead of charge.  For example, if you set the computer to shut down when the battery level drops too low or set the low battery level at too high a percentage.The simplest way to deal with these settings is to restore them to the default.

For MAC Laptops: 

Check your energy settings. Open Systems Preferences from the Dock or your Applications folder. Click on Energy Saver and check both the "Battery" and "Power Adapter" setting tabs. In rare cases, a sleep setting set too low can look like a battery charging issue. 

6.Power management software in Windows Vista

Understanding battery charging issues
If the laptop does not indicate that the battery is charging, the most likely that the battery itself is operating correctly, but its power management software may have become corrupt. In order to solve the problem, you need to uninstall and reinstall the power management software by using the Device Manager. Those steps will explain how to uninstall and reinstall the ACPI Battery listings in Windows Vista, and how to obtain and install updated BIOS files, if needed to correct other battery issues.

1. Click Start and type device in the search field, then select Device Manager .
2. Expand the Batteries category.
3. Under the Batteries category, right-click the Microsoft ACPI Compliant Control Method Battery listing, and select Uninstall .
WARNING: Do not remove the Microsoft AC Adapter driver or any other ACPI compliant driver.
4. On the Device Manager taskbar, click Scan for hardware changes .
Alternately, select Action > Scan for hardware changes .
Windows will scan your computer for hardware that doesn't have drivers installed, and will install the drivers needed to manage your battery's power. The laptop should now indicate that the battery is charging.
