I have the following problem with a XPS 13 (L321X, Early 2012), running Windows 7 x64:
Ever so often the display will be corrupted for brief moments. This only happens when the device is running on battery power. The issue does not occur if an external monitor is connected.
Steps taken so far:
- Drivers updated to the latest version available from Dell
- BIOS updated to the latest version
The problem still persists. Any ideas as to how to solve the issue would be greatly appreciated.
Best regards,
Frank Becker
