How to fix a slow Acer Aspire w700 after upgrading to Windows 8.1

When I first got my Acer Aspire w700, it was a dream. It was by far the fastest computer I had ever owned. I was quite disappointed when I started having slowness after an upgrade to Windows 8.1. I tried many different options, guessing variously that there were problems with the Bluetooth drivers (after all, it was mainly a problem when I was on battery power and thus using my Bluetooth keyboard and mouse), Office 2013 (since it had the new smooth typing transitions), and power management.

I hope this post isn’t too redundant, but I know that various search times failed me time and time again before I determined the issue. Hopefully this post can help others find the solution more clearly than an answer buried in just the right support thread. I can’t guarantee this will fix your system, but it worked wonders in my scenario.

If you want to quickly identify if this is the same problem, see if the typing speed is significantly more delayed when the only change made is from being plugged in to being unplugged. If being unplugged changes the speed greatly, this is probably the issue.

1. Go to power options

Open power options by right clicking on the battery icon in the system tray and clicking power options. Alternately, go to the start screen and search for Power options.



2. Next to the current power option, which is probably Balanced, select Change Plan Settings

I am using the default option of the Balanced plan on both battery and AC. I recommend switching to this option if you have changed it. Normally, just click to change the plan settings.



3. Click Change advanced power settings

4. Disable Low Power Mode Setting
on battery

You then get the dialog box displayed. First expand Intel(R) Dynamic Platform & Thermal Framework Settings, then Low Power Mode Setting. Ensure that it is Disabled for both battery and plugged in.







5. Click OK to apply the new settings.

I can’t guarantee you will get as good of battery life with this setting. However, for me, after upgrading to Windows 8.1 on this computer, many activities became almost unbearably slow on battery power. I have not had any other repercussions from changing this setting. I hope that this helps some others who were likely as confounded as I was!
