Microsoft rolls out firmware update for faulty Surface Pro 2 tablets

Microsoft has begun rolling out a firmware update that will fix problems introduced by a faulty December 2013 update to its Intel-based Surface Pro 2 tablets.

The company said that the update will address the unexpected sleep and shutdown issues and battery drain behavior experienced by a small number of Surface Pro 2 customers, who installed the December Windows Update, Cnet reports.

The company also said that this should have no impact on users already running the October Windows Update.
