Surface Pro firmware update brings battery reliability improvements and more

Microsoft recently began rolling out a fresh set of firmware updates (opens in new tab) to the Surface Pro (2017). Available for both the standard Surface Pro and Surface Pro with LTE, the updates resolve a potential security issue and improve battery reliability, Microsoft says.

Here's a look at what's new for Surface Pro:

  • Surface System Aggregator Firmware – Firmware - 234.2110.770.0 resolves potential security vulnerabilities, including Microsoft security advisory 180002 (opens in new tab).
  • Surface System Aggregator Firmware – Firmware - 234.2110.1.0 improves battery reliability.

The Surface Pro with LTE has received the same fixes, but each includes a different version number. Here's a look:

  • Surface UEFI – Firmware - 233.2110.770.0 resolves potential security vulnerabilities, including Microsoft security advisory 180002.
  • Surface System Aggregator Firmware – Firmware - 233.2111.256.0 improves battery reliability.

According to Microsoft's value indicator, these updates should also improve battery life. If you're using a Surface Pro, you should able to grab these updates now via Windows Update.

However, checking our own Surfaces (including those on Windows Insider Program, Release Preview) are not seeing the System Aggregator Firmware (we already had the new UEFI update). That means this could be a slow rollout as Microsoft tests the waters.

  • I have the 2017 SP.  Not seeing this update.
  • I already have the UEFI, but not System Aggregator Firmware. Added a note about it.
  • Need an update to my Surface Pro 3's battery life (i7). It's gone from ok -> not great -> awful in the past couple months. I'm lucky if my battery lasts 2.5 hours now, which is pretty bad.........note: other than updated Windows OS, store apps, and Office, I have the same software installed as I did 3 years ago, and I hardly use desktop software. I mostly use it to markup drawings (I'm an Architect), remote into my work PC, or take notes.
  • My Surface Pro3 i5 128gb version got like that when I upgraded from Windows 8 to 10 years ago.
  • I'm guessing this is a slow rollout?
  • Ever since the fall creators update my original Surface Book has pretty crappy battery life and the sleep issue is back. If i close my surface to sleep overnight with a full battery, in the morning, it's drained about half.
  • may want to do a backup/ clean install
  • FWIW, I received these two firmware updates on the fourteenth of March: they popped up after installing the Cumulative and Adobe Flash updates (Standard Surface Pro in the United States)
  • One of these fixes the situation where 60 seconds after closing the cover, the screen will turn back on when the Surface is docked.
  • Better battery life sign me up!
  • Battery, Surface and Reliable in the same article? Lol. Whatever improvement they promise and how great the device is, I don't believe this thing will ever get up to at least 4 hours on a single charge. Mine is basically plugged in 100% of the time because of this. Even got only 30 minutes once.. Oke... full adobe suite running + +- 5 other apps, but 30 minutes? Looks like a Renault Twizy, we promise 100KM range, but actually it are 60 under the best weather conditions, so basically on a normal day you have 30. Message to any company: Please just be honest about your batteries. Better promise something less so your customer would be amazed if they get more out of it than you promise...
