Windows 10: Unplugging Surface Pro slows computer

High Performance mode is activated and doesn't seem to change when unplugged, yet performance drops. Changing power settings doesn't seem to do anything. What other settings can I change to make the laptop to stop limiting things when unplugged? I don't care about battery drain, I care about performance. Need help as being unplugged is a reason why a laptop is convenient.

Hi ChrisWaters3,

Thank you for writing to Microsoft Community Forums.

Could you please help me with the below information:

1. Does the battery drain out, if the tablet is not connected to peripherals?
   
   
2. Which version of Windows you are using? (To check, type: winver in start menu and hit enter.)
   

I understand how something like this can try your patience. This issue is an indication of faulty drivers or incompatible driver.
However, I suggest you to follow the troubleshooting steps mentioned below:

Method 1: Check the drivers.

Step1: Battery driver

1. Press Windows andR
   key together on your Keyboard.
2. Type devmgmt.msc and hit enter.
   
3. Click on view on top > Select Show hidden devices.
   
4. Expand the Batteries option from the list.
   
5. Select the ACPI Compliant Control Method Battery> right click on the driver and click on
   Properties.
6. Click on Driver tab > check if you have the option to
   Roll Back Driver.
7. If yes, Roll back the driver or uninstall it and restart the computer.
   

Uninstalling the driver will be automatically installed after the system is restarted. Check if the issue is fixed.

Step 2: Keyboard driver.

1. In the Device manager, go to ‘Other devices’, you will find
   Unknown devices.
   
2. Double tap on the unknown device > click on
   Driver tab> click on update driver.
   
3. Select browse my computer for driver software> Click on Let me pick from a list of device drivers
   
4. Select keyboard, then click ‘Next’.
   
5. Select HID Keyboard device and click finish.
   

Method 2: Run the toolkit.


Note: If your Surface is managed by your work or school, check with your organization's IT department before running the tool.

I would suggest you to run the toolkit provided by Microsoft on
Fix common Surface
problems using the Surface Diagnostic Toolkit

If the above steps, doesn’t fix the issue. I would suggest you to follow the steps mentioned in the article on
Surface Pro 3 Battery
FAQ for the Surface Pro Embedded Controller Firmware update.


Hope it helps.

Surface Pro 4 WiFi Slow Connectivity

Hello there,

After rattling my brains over what it may be I found my own solution.

I did the registry changes suggested on the internet - no fix

I did the driver rollback/uninstall/reinstall - no fix

I changed the wifi driver band from auto 2.4ghz/5ghz - no fix

What fixed it for me was going to my router settings and changing it from Long Preamble to short pre amble.

Went from 1mbps to 30mbps (my limit from where i am from)

Hope this helps. My router is a netgear.
