Microsoft is unable to find a software or firmware fix for Surface Pro 4 tablets affected by screen flickering, so it's launching a replacement program for them. Any Surface Pro 4 units experiencing the problem will be covered for up to three years from the time of original purchase. The Verge reports: The annoying flickering has been well-documented on Microsoft's support forums, with some users taking drastic steps like putting their Surface Pro 4 in a freezer to temporarily fix the issue. Back in February, Microsoft said it was closely monitoring the situation, and the company came to the conclusion that there's no convenient fix. Some customers have already paid for a screen replacement to stop the flickering since the problem typically arises when a machine is out of warranty; Microsoft says they'll be "offered a refund." The company notes that this three-year coverage doesn't extend to other problems your Surface Pro might experience outside the warranty period; it only applies to the screen issue. Replacement devices are refurbished -- not brand new -- Surface Pro 4s.
