Yes, it's fine to charge your laptop to 100%. About once a month, allow your battery to run down to about 20%, then charge it back up to 100%. This allows the chemicals inside the battery to get mixed up, which will extend the life of your battery.

You could have a faulty AC adapter or plug. If the problem is the AC adapter, you'll need to replace the charging cord that came with your computer. If the plug where you insert the AC adapter is broken, you'll probably need to have a technician replace that. Or, there might be a problem with the motherboard. Sometimes the charging circuit on the motherboard can go bad. Unfortunately, that usually means a new motherboard replacement.

Why does my laptop only work when the laptop is plug into the wall? The laptop won't work and turn on unless it's plugged into the wall. Do I need to replace my laptop battery?

Sounds like either your battery isn't charged, is dead, or not inside your laptop. For Windows: when your laptop is on, you'll see a battery icon in the tray. It'll have a line through it if you don't have the battery installed or if it's dead. If the charge won't pass 10%, try using a different AC Adapter (get one with the right voltage by referring to your laptop's manual). If you have a Mac laptop, the battery isn't removable, so you're either using the wrong charger (and it's not charging your batter) or your battery is dead. Take it to a Genius bar to try other adapters to narrow down what the issue is.

You might need to get a new battery since it's way past the expected lifetime. I had the same issue and bought a new battery and AC Adapter and got more time on the battery. You could also try to optimize battery life by turning down your screen brightness, the sound levels, unplugging any peripherals, and anything suggested in this article.

You may need to press the power button quickly to pull up a menu on your screen to hibernate or sleep. Refer to your laptop's manual for information for your specific laptop.

If you plug in before playing, you'll be able to play longer. The demand for the graphics card will drain your battery faster, so playing only on battery power will give you a short amount of time to play.

That sounds like a non-battery-related issue. The screen may have been damaged while you were changing the battery.

Question

How do I save battery power on an iPhone 7 plus?

Community Answer

Turn your Power Saving mode on. It will save about 65% of battery. When you turn it on it should save battery. It may make your tapping a bit slower, but at least your battery won't go out as quickly.
