How to Run laptop without Battery use. Just AC connection

Greetings:

Would appreciate it, if someone knows how to set up a laptop to run directly on AC power, and not use battery.

Simply remove the battery.  If the system won't run on AC power only, something is wrong (other than the battery) - either the adapter or system board is faulty.

In addition, current recommendation is to store the battery with about a 60% charge if you will not be using it for an extended period of time. I would put it back in periodically and see how the charge is doing. Shouldn't self discharge too fast, but it doesn't hurt to check. If a Lithium battery is allowed to discharge too far, it might not be able to be recharged.

I have an Inspiron N7010 and it is plugged in to electricity all the time.  IF I unplug it, about how long will the battery last?  It is about 98% battery power.

Thanks

I didn't say that quite right, but thank you for that added info.   I would like to know how many hours the battery will last.

It will last until power gets down to 3% and then shut off.

There is no single answer.  WIth aggressive power management (dim display/hard drive spindown/low CPU speed) a 9-cell battery, you could see four hours or more.  With a 4- or 6-cell and/or constant use with a bright display and no hard drive spindown, you could see less than two hours.

I want to use my laptop on AC power, and I have never done this before. How do I use it on AC power, are there any precautions I need to know? Are there any risks? Thanks.

You do not need a battery i place to use a laptop. It now works like a desktop - no battery backup in case of a power failure.
