Is there a way I can get a notification to appear when my battery on my laptop is at 100%. I have a Surface Pro 3 with windows 8.1. I am needing to know this so i can unplug the charger when it is fully charges and so i do not wear out the battery.

Is there a to get a notification when a laptop battery is 100% charged?

The script below should do what you want with some appropriate tweaking.

Save below as battery.vbs and put a shortcut to "wscript path-to\battery.vbs" in your startup folder.

set oLocator = CreateObject("WbemScripting.SWbemLocator")
set oServices = oLocator.ConnectServer(".","root\wmi")
set oResults = oServices.ExecQuery("select * from batteryfullchargedcapacity")
for each oResult in oResults
   iFull = oResult.FullChargedCapacity
next
while (1)
  set oResults = oServices.ExecQuery("select * from batterystatus")
  for each oResult in oResults
    iRemaining = oResult.RemainingCapacity
    bCharging = oResult.Charging
  next
  iPercent = ((iRemaining / iFull) * 100) mod 100
  if bCharging and (iPercent > 95) Then msgbox "Battery is at " & iPercent & "%",vbInformation, "Battery monitor"
  wscript.sleep 30000 ' 5 minutes
wend

Answer 2

I think David's answer answers your question, but, I'll provide some additional information as I believe this to be relevant and useful.

Lenovo have some software which does what I think you want, called Energy Management.

The recent version allows you to

STATEMENT DESCRIPTION:

Comparing with the previous versions, Lenovo Energy Management 6.0 has been improved with the following new features:

1. Add “Battery Level” in Battery Information.

2. Redefine “Battery Health”.

    (1) Change limited capacity of “Best battery heath” to 45%~50% from 80%;

    (2) Detect battery status by hardware automatically;

    (3) Pop up a hint box to suggest users to switch the mode;

3. Add hint when using unauthorized battery.

4. Remove the scheme of “Power Saver”.

5. Remove “Advanced Settings” of “Super Energy Saver”.

There is a review of an older version working with the Surface 2 which suggests it will work with the Surface 3

However, this post on SuperUser suggests other wise (again for Surface Pro) - How can I limit battery charging on a Surface Pro (2) or Windows 8(.1)?
