I'm going to buy a Microsoft Surface notebook that does not have the capability to easily remove the battery. I'm also going to be near a powerpoint for around 90% of my usage of this notebook.

To maximize the battery life on my previous (old) laptop, I would take out the battery whenever I was near a power point (which was most of the time). Since I'm no longer able to do this on the Microsoft Suface, I am looking for software that can both (i) completely disable the battery from being used whenever AC power is plugged in, and (ii) make it such that the power is only powering the computer and is NOT charging the battery.

Put another way I'm looking for software to "trick" the notebook into thinking that the battery has been pulled out.

As far as not charging the battery is concerned, the laptop will automatically shutoff charging when the battery is charged. You do not need to remove the battery to do so.

The only reason you would need such a software is to prevent a large number of shallow discharges of the battery if you unplug it for 20-30 minutes and plug it back in repeatedly, or want to keep the battery at a charge level lower than 100%

But since I move around for short bursts here and there as I move around the office I don't want it to go from 100% to 98% to 100% to 98% many times each day. I've read that this is bad for the battery. Also I've read that going fully to 100% is bad for the battery life. –  Jameson Feb 27 '13 at 9:12
    
@Jameson yes, that is true. In that case, you should be looking for a software to configure custom charge thresholds. (Such as the one which comes with a Thinkpad if you have used one) –  Akash Feb 27 '13 at 9:15
    
Does the threshold completely disable the battery in every way (with respect to both charging & usage)? Or would the battery still be doing something? –  Jameson Feb 27 '13 at 9:27
    
@Jameson Well, not exactly. If you set a min threshold of 60% and max of 90%, the battery will not do anything as long as it is above 60%. If you disconnect from mains, the battery will power the device. When you plug it back in, the battery will be charged (to 90%) only if it is below 60%. So, it does get used in the sense that your device will not be hard shutdown if you pull the power cord. –  Akash Feb 27 '13 at 10:12

1 - common, all battery charger unit cut the charging after fully charged of the battery.

2 - you want to reduce charge cycle of battery BUT if you left battery away, with full charge, it make your battery weak after a while.

3 - all new batteries has no issue with charging from middle of power, that mean there is no need to charge your battery exact at the time of fully empty.

4 - you lost many data if you remove your battery and suddenly you lose power.

5 - Microsoft surface is a table not a notebook that means they make it to use it on the go.

6 - take a look at Lenovo think pad helid from here, it is best combination of table and laptop.
