Laptop automatically restarts when the lid is opened.

After closing my laptop lid and opening it later, instead of waking up from sleep mode, the laptop is unexpectedly performing a full restart. This issue persists even after adjusting the settings to disable automatic restart in Advanced System Settings. To troubleshoot this further, I re-enabled automatic restart but now encounter a different problem - the screen remains black upon opening the lid, with no response to input from the mouse or keyboard. I am forced to perform a manual shutdown each time this occurs. How can I address the unexpected restarts and the black screen issue that only arise when I close and reopen the laptop lid?
