Hi,
My XPS 15 laptop which is about 4 years old, has begun unexpectedly shutting down or going into sleep mode after different lengths of time sometimes within seconds of restarting or powering back up from the sleep mode.
The monitor goes dark and the power button flashes or the system simply shuts down. The power button restarts the system after several presses. However, the system repeats the problem making it impossible to use the computer without it either going into sleep or shut down mode again.
I have taken the following actions without any effect on the problem..
- I have the latest updates for windows 7 installed.
- I have not added any new hardware that might have caused this.
- I have followed various online suggestions such as turning off usb driver in device manager
- The power settings have all been changed to 'NEVER' for shutdown or sleep within both battery and power options.
- I have replaced the battery (but not the powercord as the symptoms occur regardless of being operated on battery or power sources.
- THE PROBLEM ALSO OCCURS IN SAFE MODE (shuts down unexpectedly).
- The laptop does not appear to be overheating as it is only on for approx 30 secs to 5 minutes before shutting down or going into sleep mode again.
Thank you for any help you can provide.
Aurora.
