Out of the box, there is a lot of unnecessary software installed. I uninstalled Norton and everything by Acer. Windows updates takes a very long time as there are major updates which have been released since these units were imaged... Update 7/18/2018: I recently tackled the really loud fan noise on these and did get an improvement. Search for Power Options > Change Plan Settings > Change Advanced Settings. Expand Processor power management > System cooling policy and set both On battery and Plugged in to Passive. The fan still activates, it is just at a lower RPM. I have not performed temp tests to compare results, so do at your own risk.
The biggest issue with the Aspire A315-51 is that 15.6-inch display, which suffers from poor visibility and a serious lack of colour accuracy. However, look past these flaws and you’ll find a perfectly decent budget laptop. Acer’s solid design work, coupled with a satisfying keyboard, respectable connectivity and decent battery life make this Aspire well worth considering as a family or student machine. Overlook the basic display and the Aspire A315-51 is a decent everyday laptop, available for a low asking price.
