Hardware Care & Maintenance Tips
Practical engineering insights from Sumit Infotec technicians to prolong your device lifespan.
Beat UP Summers: Thermal Paste
When temperatures cross 42°C in Mainpuri, factory thermal paste dries out, causing laptop CPU throttling and motherboard power IC burnouts. Re-paste annually.
Read Laptop GuideMonsoon & Lightning Care for CCTV
Outdoor CCTV cables can channel high voltage lightning surges directly into your DVR. Ensure our conduit casing and dedicated SMPS surge grounding are in place.
CCTV Best PracticesLaser vs InkTank: Real Costs
For coaching notes, legal briefs, and shop billing, a laser printer refilled at ₹250 gives ~2,000 pages (12 paise/page) with zero risk of printhead dry-out.
Refilling AdvicePreventing Earbud Battery Drain
Never leave wireless earbuds in direct sunlight or fast chargers exceeding 5V/1A. If one earbud dies quickly, replace only the coin cell instead of buying a new pair.
