Frequently Asked Questions

Q: Why does my laptop only shut down when gaming or doing intensive tasks? A: This is classic overheating. Your laptop's thermal protection kicks in to prevent damage. Clean the vents and consider a cooling pad immediately.

Q: My laptop shuts down immediately when I unplug the charger. What's wrong? A: Your battery is likely dead or severely degraded. Try removing the battery and running on AC power only to confirm.

Q: Can I prevent laptop shutdowns by changing Windows settings? A: Sometimes. Disable fast startup, reset power plans, and ensure Windows is updated. However, hardware issues require hardware solutions.

Q: How do I know if it's a software or hardware problem? A: Boot from a USB drive with a different operating system (like Ubuntu). If shutdowns continue, it's hardware. If they stop, it's software-related.

Q: Is it safe to keep using a laptop that randomly shuts down? A: Not recommended. Random shutdowns can corrupt files and may indicate failing hardware that could damage other components.

Q: How much does professional laptop repair typically cost in the UK? A: £50-150 for most common issues. Always get a quote first. Sometimes buying a new laptop is more economical than repairing an old one.

Q: Which laptop brands are most reliable for avoiding shutdowns? A: ThinkPad (Lenovo business line), MacBooks, and business-grade Dell Latitudes tend to have better build quality and thermal management.

Q: Should I attempt DIY repairs on my laptop? A: Only basic maintenance like cleaning vents and updating software. Leave component replacement to professionals unless you have experience with electronics repair.
