A laptop in Vikhroli or Kanjurmarg that runs hot is usually suffering from a dust-clogged heatsink, dried thermal paste or a failing fan, and all three can be fixed without replacing the machine. Xigox offers free doorstep pickup across both neighbourhoods and the JVLR corridor, a written quote before work, a ₹350 inspection fee refunded if you go ahead, and a 90-day warranty. This guide shows how to confirm overheating, what to try first and when to hand the laptop over.
How can you tell a laptop is overheating and not just busy?
A busy laptop gets warm and then settles. An overheating one gets hot, slows down and sometimes switches itself off. The clearest proof is throttling: the processor lowers its own speed to protect itself. In Task Manager's Performance tab, a clock speed that falls while the load stays high suggests heat. A free tool such as HWiNFO shows temperatures too.
Readings that sit in the 90s degrees Celsius while the clock speed drops point to thermal throttling. Many laptop processors will shut down to protect themselves close to 100 degrees. Use the table below to match what you see with the likely cause.
| What you notice | Likely cause | Quick check |
|---|---|---|
| Fan loud even at light tasks | Background load or dust | Sort Task Manager by CPU |
| Fast at first, slow after ten minutes | Thermal throttling | Watch clock speed against temperature |
| Shuts off in long sessions | Heat protection or a weak fan | Note how long it runs before it shuts down |
| Grinding or rattling fan | Worn fan bearing | Stop heavy use, book a check |
| Hot only while charging | Charger fault or battery problem | Check whether the base bulges |
The last row deserves care. A swollen battery produces heat and a bulging base, and it is a safety issue, not just a cooling issue. Stop charging and book a replacement promptly. Our overheating causes and fixes guide covers other causes in more detail.
What can you safely try at home before booking?
Several free steps help, and none risks your hardware. Work through them in order, and stop at the point where the heat comes under control. If the problem persists after all five, the cause is almost certainly inside the case, where dust and old paste hide.
- Change the surface. Use a hard, flat desk, never a bed or sofa. Raising the back edge slightly improves airflow. Keep the vents clear.
- Find the culprit app. Sort Task Manager by CPU and close anything unexpected. Browsers with many tabs and background updaters are common offenders.
- Cap the processor. In Windows advanced power settings, setting Maximum processor state to 99 per cent disables turbo boost on many laptops, which cuts heat noticeably. Performance drops a little in exchange.
- Blow out the vents carefully. Use short bursts of compressed air with the can upright, and hold the fan still with a toothpick so it doesn't over-spin.
- Update the BIOS and drivers. Manufacturers sometimes adjust fan behaviour in updates.
Equally important is what not to do. Don't use a vacuum cleaner on the vents, because it can generate static and spin the fan too fast. Don't open a laptop that is still under manufacturer warranty without checking the terms. And don't keep running a machine that shuts itself off, since repeated overheating shortens the life of the battery and board.
What does a professional thermal service involve?
A proper service opens the case, removes dust from the heatsink fins and fan, cleans off the old thermal paste, applies fresh paste, and checks that the fan spins freely. A worn or noisy fan is replaced, and the laptop is tested under load afterwards. Paste dries out over the years, which is why a laptop can run hot even when it looks clean.
The price depends on the model, not just the task. Some laptops need only the base removed, while others need the keyboard or the whole board lifted to reach the heatsink. Fan availability matters too. Read about thermal paste replacement and laptop fan replacement, or see the wider laptop overheating fix page.
If heat has already done damage
Sometimes the inspection finds knock-on faults. A heat-aged battery may need replacement, with an indicative range of ₹1,499 to ₹4,999. Rarely, sustained heat contributes to a board fault, and motherboard repair has an indicative range of ₹2,999 to ₹8,999. For a gaming or CAD laptop with a failing graphics chip, we confirm the fault by testing and advise on a replacement or upgrade route. See gaming laptop throttling fixes for more.
How does a laptop's cooling system work, and why does it fail?
A laptop cooling system moves heat from the processor to the outside air in three stages, and each stage can fail. Understanding them explains why a clean often works. Heat flows from the chip into a copper plate through a layer of thermal paste, travels along heat pipes to a finned heatsink, and is blown out through the vents by a fan.
Dust attacks the last stage. Fibres and lint collect on the fins and block the airflow, so the fan spins harder yet removes less heat. Paste attacks the first stage: over the years it dries, cracks or migrates, leaving a poor connection between chip and plate. A worn fan bearing, the third failure, shows up as noise or a fan that no longer reaches full speed.
Thin, powerful laptops, including gaming and workstation models, have the least margin because they pack a lot of heat into little space. That is why they tend to show trouble first, and why a proper service clears more than a quick blast of air can. If the vents are blocked on a laptop that has never been cleaned, a thorough clean can make a real difference.
Why do students and engineers feel this first?
Long compile, simulation, rendering or gaming sessions hold a laptop at full load for hours, which is exactly when weak cooling shows up. If you study or research near IIT Bombay, or run engineering and design software anywhere in Vikhroli and Kanjurmarg, a clean and fresh paste every so often keeps performance steady. It also helps the laptop last through a long project.
How does pickup work in Vikhroli and Kanjurmarg?
Call or WhatsApp +91 74997 61196 with the model and symptoms. We collect free from Vikhroli West and East, including Kannamwar Nagar, Tagore Nagar, Surya Nagar and Pirojshanagar, and from Kanjurmarg West and East, plus Bhandup and the JVLR Junction. We also serve addresses off LBS Road and the Eastern Express Highway. Pincodes are 400083 for Vikhroli and 400042 for Kanjurmarg.
Landmarks such as Godrej Garden Enclave, The Park Vikhroli, Godrej and Boyce, R-City Mall and Kanjurmarg Metro Station help us find your door. We are open 9 AM to 9 PM every day, and most common repairs finish the same day. See the Vikhroli and Kanjurmarg pages for coverage details.
Frequently asked questions
Does a cooling pad fix an overheating laptop?
It helps a little by improving airflow under the base, but it can't clear dust or replace dried paste. Treat it as an extra, not a cure.
How often should thermal paste be replaced?
There is no universal interval. We suggest a check when a laptop is several years old or has begun to throttle, and we assess the paste and the fan during the service.
Can overheating permanently damage a laptop?
Yes. Sustained heat ages the battery, can contribute to board faults over time and may make the laptop unstable. Early cleaning is far cheaper than repairing the damage.
Will opening my laptop affect its warranty?
If it is still under manufacturer warranty, opening it may affect cover. Check the terms or use the manufacturer's service route first. Our own repairs carry a 90-day warranty.
If your laptop is running hot, you can book a free pickup or ask for a quote and we'll confirm the cost in writing before any work begins.
