Question

Should you always charge your battery when it reaches 40%?

Community Answer

You can charge it whenever you like. You could wait until you get a warning that the battery's getting low (usually around 10% or so), or you could charge it earlier than that. This has no effect on the life of the battery, unless you're using the computer while charging it, which will shorten it a little bit.

Question

My laptop's battery was working fine until I reinstalled Windows. Now it drains after 30 minutes. What happened?

Community Answer

Your laptop's battery is damaged. Replace your battery. This might have happened because of charging your laptop all the time even when it's fully charged.

Question

How "low" should I go before charging? Is 20% good?

Community Answer

It would be better to plug your laptop in when your battery is at 25%. If you are at home, consider keeping your laptop plugged in; it saves a lot of trouble of low battery life.

Question

How can I make "Just Cause 3" (or other cpu-intensive game) use less power?

Community Answer

You can end every other task, then check if it's running smoothly. If this does not work, then download contig.exe and learn how to use it. You can find the tutorials on Google.

Question

My Lenovo seems to discharge very quick and turns off without warning. What is the problem?

Community Answer

If you have demanding applications running in the background, they drain your battery faster. Try to open only what you're actually using each time.
