Is there a charging light on the charging brick?

Unplug the charging brick from both the laptop and the wall outlet.

Plug the charging brick in the wall outlet. Does the light come on?

Now connect the laptop to the charging brick. Does the light remain on?

Power on the laptop. Does the charging brick light remain on?

If the charging brick light goes out when connected to the laptop or when the laptop is powered on, then you have a problem with the laptop (DC-IN connector board, charging circuit on the motherboard, and/or the laptop battery).

Take laptop and charging brick to local tech repairman.

Similar problem started for me a few days ago but now the battery won't charge past 85%. I can't seem to get to the bottom of the issue. Any ideas?

Go into your Device Manager, under Batteries, Uninstall Microsoft ACPI-Compliant Control Method Battery, then reboot the laptop. The Microsoft ACPI-Compliant Control Method Battery should be detected after the reboot. Check battery icon. If the charge indicator hasn't changed (still 85%). then I would suspect you should replace your battery soon.

Your battery should be exercised at least once a month (unplug charging brick from laptop and run the laptop), keep an eye on the battery icon. How quickly is the battery drained? Faster voltage drain would indicate a weaker battery. After 15-30 minutes, power down the laptop, connect the charging brick and power the laptop back on. Check the battery icon (should show charging), the higher the percent charge would indicate condition of the battery. As the battery ages, the percent charge decreases. If below 75%, I would replace battery.

If you use your laptop daily, and you have the laptop connected to its' charging brick all the time, it's normal that the percent charged indicator will slowly fall. Exercising the battery occasionally can help. Still, it should be expected to change the battery after 4 or 5 years.

Another note: Keep and eye on the power LED on the charging brick. You want to see the green LED (check after loss of household power). Plug the charging brick into a surge protector or better yet, a battery backup. The charging brick can go bad. I would swap the charging brick along with the battery (every 4 or 5 years).

I just saw this and would like to know what knowledge or evidence you have to suggest this?

Contrary to some recommendations, you don’t need to completely discharge a lithium-ion battery and then recharge it to somehow reboot or calibrate it – this is a destructive practice that’s very hard on your battery. Whether or not it’s a smart idea to perform a complete discharge a couple of times a year remains an unanswered question. Generally, the consensus seems to be that letting your battery discharge (without bottoming it out — aim for around 20 percent) and then charge it when possible is the best practice.
