Nitro V15 Laptop performs poorly and crashes when plugged in

I have a Nitro V15 that is a 4 to 5 months old and performs perfectly when on battery. But the moment I plug it in the fan goes wild, performance decreases, games and apps keep crashing and the laptop crashes as occasionally as well. The crash is always the kernel security check failure one. What's causing this and how can I stop this?

Hi @nilsh13 ,

Your Nitro V15’s crash when switching from battery to AC power likely stems from a combination of aggressive power mode switching and a possible EC (Embedded Controller) or BIOS issue.

🔍 What’s Happening

On battery, Windows uses Best Power Efficiency mode with passive cooling.
When plugged in, it may switch to Boost Mode: Aggressive Guaranteed, triggering max CPU/GPU performance and fan speeds.
If the EC firmware or BIOS mishandles this transition, it can cause instability — especially if voltage regulation or thermal thresholds aren’t properly managed.

💥 Kernel Security Check Failure (BSOD)

This error is often linked to:

Driver conflicts (especially GPU or chipset)
BIOS/EC bugs — several Nitro V15 users have reported blue screens after BIOS updates
Corrupted system files or unstable RAM

🛠️ What You Can Try

Update or reset BIOS/EC firmware
- Acer has a thread discussing EC reset steps for Nitro V15:

Clean reinstall GPU drivers
- Use DDU (Display Driver Uninstaller) in Safe Mode, then reinstall the latest drivers from NVIDIA or AMD.
Run memory diagnostics
- Use Windows Memory Diagnostic or MemTest86 to check for RAM faults.
Adjust power plan settings
- Set both battery and plugged-in modes to “Balanced” or “Best Power Efficiency” to avoid sudden performance spikes.
