Troubleshooting a Non-Responsive Laptop with Active Fan and External Indicators
Experiencing hardware issues can be challenging, especially when your device exhibits signs of power while other components remain unresponsive. Recently, one user reported a similar situation with their Acer Predator Helios 300, which has been a reliable gaming companion for over a year. Below is a detailed account of their issue, followed by professional troubleshooting advice to help identify and possibly resolve the problem.
User Description of the Issue
The user’s Acer Predator Helios 300 had been functioning well for over a year, primarily used for gaming titles such as Valorant and Genshin Impact. One evening, after leaving a Twitch stream running overnight, they fell asleep with the laptop still active.
Upon waking, the user believed they pressed the power button to shut down the laptop while it was fully operational. Since then, the laptop exhibits the following symptoms:

The described behavior suggests that while the system’s power supply and some components are active, critical parts like the display and input devices are not functioning. This kind of issue can stem from several underlying causes, including:
- Hardware freeze or crash
- Power management issues
- Firmware or BIOS problems
- Faulty or loose hardware connections
