HI Carol, You can adjust the performance of your battery. High performance gives around 3:15 hours and low performance gives 4:40 hours on my computer. I like this computer in general. Hope that help!

If you're online, about 2 hours. If you're offline (i.e Office) somewhere between 4-5.

It depends on your performance settings and what you're doing on the laptop. I use mine with high performance and generally use light programs (MS Office) and web browsing and it generally lasts about 2-4 hours depending. The life of the battery can extend quite beyond that I believe by turning off features and downgrading performance, but I have not really explored those features fully.

If you can take the battery out and run your laptop on just the power adapter - the battery is dead. My battery only lasted 5-6 months. Initially I got 3 hours on a charge - no more.

I am not sure if you can use it without an adapter. I would suggest you make sure by contacting customer service at IRobot. Their customer service has been very good in the past.

Adapter, plug in, and battery back up but assume you would not use the batteries as main power unless you had to.

I bought 2 Innotabs for my 2 daughters this Christmas. The batteries last 24 hours, so now I have to go buy the power adapter.

It comes with about 20 adapters (you need one to fit your computer and one to fit the power source) but the instructions don't specify specific models, only manufacturers. I have a Samsung and the adapters shown for Samsung did not fit my laptop but by trial and error I found the adapters that fit. I have only used it once but it worked fine. It does take at least 24 hours to charge the battery and my only reaches 86% charged, which may be the max but I don't know.

It's pretty good... I got up to 2 days use with mine without charging. And when I gave it to my friend in Africa.. He never complained about battery life despite the fact their wasn't steady power supply where he lives.

I would guess that it depends on the vehicle. Some leave the power to those adapters active all the time. If your device stops charging once you have shut off your vehicle then it should be fine to leave it plugged in.

Yes!!!!!! It charges our battery so that we are able to unplug and use for hours(about 4 hours) without the adapter. Great price and it worked very well for us.

Hi. The adapter does not come with it. That would have to be purchased separately.

At least the one I bought did not came with power adapter. It requires eight "AA" batteries and the life if very low. You need to buy the power pack apart.

There is no AC adapter. It's battery operated by D batteries. I only activate it when I'm going to be away for one night or more (about once a week) but I'm still on the original battery for 6 months now.

You dont need any adapter. Everything you need comes with it. Hope this helps.

Sorry, but I didn't get an adaptor with mine, although I will probably look to see if I have one that fits it. The battery life is not what I expected, nor is the brightness.

No battery. Even finding where to plug in the adapter is a bit more of a problem than it should be.

The batteries are necessary to keep the memory of data and setting. Other user find out that using the battery alone without AC adapter drain the battery quite fast, therefore I recommand use the AC adapter whenever possible to save battery cost.

The adapter I have is AC powered and not battery operated. I don't understand the question: "without AC adapter..." and "rather than battery operated." If it is not powered by AC or a battery, how is it supposed to be powered. This unit plugs into an earphone receptacle on the computer. These ports don't supply power like a USB port does. I don't think my answer helps much.
