1 How to Diagnose and Fix an Overheating Laptop One of the most common issues with aging laptops is overheating, something many people aren t sure how to fix. We ll help you figure out what s causing the heat and how to keep your notebook functioning at a lower temperature. Overheating computers can cause a lot of problems, from seemingly random blue screens to data loss. You might not even know that it s the root of your issues, and before you know it you have a burnt-out motherboard on your hands. Let s go step by and step and see how to deal with overheating computers. We ll be dealing primarily with laptops, but most of the same principles apply to desktops as well. Find the Heat Source: Air Flow and Heat Transfer The first thing you need to do is figure out where the heat is coming from. No air flow means no heat transfer, so figure out where the air vents are. Are they blowing hot air, or is there barely a breeze, even when the fan is overtaxed? Yusratech ICT Solutions Page 1

3 Unscrew the fan doors and you should be able to lift out the fan and clean everything with a can of compressed air. If you find that a fan is spinning erratically, you may want to try lifting the sticker off of the axle and putting a drop of mineral oil to keep it going. Yusratech ICT Solutions Page 3

4 You can also try to look up the part number from your laptop s user manual or by searching your laptop model number online. Once you have that, you can find replacements pretty easily on ebay and the like. Dying Batteries: There are plenty of different types of batteries, and many different schools of thought on battery maintenance and life span, but one thing that seems pretty unanimous is that batteries aren t meant to be stored at 100% or 0% capacity. I know plenty of people who buy laptops and always keep the charger in, never actually using the battery. You can definitely expect to kill your battery s health this way, since you re essentially storing the battery when it s full. Bad batteries don t just give out really quickly, they can generate heat. Yusratech ICT Solutions Page 4

If you can t find one, you may consider using your laptop as a desktop and remove the overheating battery completely from the equation. Persistent Overheating: If you ve taken the air vents and battery out of the picture and you re still having problems, then you might have a more persistent heat issue. Sometimes a dusty hard drive can cause heat problems and data loss. Some laptops just run hot, even without a major load on the CPU. Try cleaning out these areas as best you can before you move on to another solution. Dust under the processor and RAM doors to get rid of any dust and debris. If you ve got a netbook or a laptop without compartments underneath, things might be more difficult. You should be able to find instructions for getting the back off so you can clean things properly.

6 Behavior Changes: Laptop owners have a lot of luxury by not being tethered to a chair and desk. We develop a lot of habits, like browsing in bed that can actually work against computers normal performance. A lot of laptops are designed with their air vents on the bottom for some ridiculous reason, so setting it down on soft bedding or carpet for prolonged use is a bad idea. You d be surprised at how quickly the heat can build up. If you have this is a habit, you might consider investing in a laptop-stand to keep the air flow unobstructed. Yusratech ICT Solutions Page 6
