Laptop won't power up with AC adapter and won't charge IROBOT 4446040 battery Boston Power SWING4400 Li-ion Battery

Many IROBOT laptop users have found that their IROBOT 4446040 Battery cannot be charged. The battery indicator on their laptop says it’s not charging even when there’s an IROBOT AC adapter connecting to their device.

If your laptop works fine while plugged in but stops working after it is unplugged, your laptop battery is bad, or your laptop is not charging the battery.

Here are some tips that can help you

1.Power down the IROBOT laptop. Unplug the power cord.

2.Remove the battery from the laptop. A IROBOT battery is located on the bottom of the laptop. Slide the locking mechanism to the right. Hold the mechanism in place with one hand while lifting the battery upward with the other hand. Release the locking mechanism once the battery is removed.

3.Plug the power cord into the right side of the IROBOT laptop while the battery is removed. Press the "Power" button to turn the laptop on. If the laptop turns on, the power cord is properly working. If the laptop doesn't turn on, ensure the electrical outlet is working by plugging in another device. If the electrical outlet is working but the computer won't turn on, the power cord is dead and needs to be replaced. If the power cord is not properly working, it will not charge the battery. Turn off the laptop and remove the power cord.

Please buy a new charger!

4.Examine the battery. Look for signs of damage, such as corrosion, dents or dings. If you see damage on the battery or battery contacts, replace the battery with a new one.

5.Clean the laptop battery. Pour a small amount of rubbing alcohol into the rubbing alcohol cap. Dip a cotton swab into the rubbing alcohol. Rub the swab onto the battery contacts, located on the battery and in the battery bay, to remove dust and grime. Dirt can prevent the battery from properly charging, so the battery should be routinely cleaned.

6.Push the laptop battery back into the battery bay. The battery will snap into place.

7.Plug the power cord into the side of the laptop. Allow the battery to charge for 8 hours or overnight. Do not use the laptop during this time, as it can slow down the charging process.

8.Remove the power cord. Press the "Power" button. If the laptop will not turn on, the battery is dead and a new IROBOT  4446040 Battery Pack should be replaced.
