Problem
Some customers have reported that their NT310 Stone laptop may intermittently beep unexpectedly. When the problem occurs, the laptop will beep every few seconds until rebooted or it shuts down.
Cause
There are several possible causes for this:
- The battery is not installed properly. These laptops have two battery clips one of which must be manually moved to the closed position on each machine.
- The system may be overheating.
- The system may be running on battery and the battery level is very low.
- Out of date or incorrect video drivers (NT310 only).
- A BIOS Update may be required.
Resolution
- Ensure that both battery clips are in the locked position, so that the battery is securely installed in the machine. The locked postition is indicated by the "closed padlock" symbols. The right hand clip in the picture below must be manually moved to the locked position on each machine - it is not a spring loaded clip.

- Always ensure that the vents on the left hand side of the unit are unobstructed. Blocking the vents on the left hand side of the machine can cause overheating.
- Ensure the correct AC Adapter is connected to the system and check the battery charge level.
- NT310 Only: Check the age of the Intel HD Graphics video driver installed. Customers with an Ivybridge processor (Core i3-3xxx or Core i5-3xxx) need to ensure that they are using a video driver from 2013 or newer.
- If you have updated to a recent video driver, or already have a 2013 video driver installed, you may benefit from a BIOS update for your system. Please see the attached articles for BIOS updates, or below:
