Laptop is REALLY hot on bottom?

Question

I have an Asus, 2 year old laptop. It used to be perfect, running quickly and everything, but recently (last two months) it has been running soooo slow and getting so hot on the bottom I can't even rest it on my legs anymore. How do I fix this??? It's so annoying!

Answer 1

Many possibilities here. Do not even attempt to remove the heat sink or whatever the earlier poster mentioned. It is a laptop so unless you're a tech, do not do anything to meddle with the inside parts.



1. Virus/Trojans/Spyware etc usually cause the system to be slow and cause excessive usage of the harddisk. As another user mentioned, run a virus scan on your machine. If you do not have one, go online and download any free ones. For now, they will do.



2. Run spyware scanners. Also go online and find free ones. If you're not comfortable, get an IT friend to assist you. Too many bogus and malicious software around.



3. Chances are your battery is also heating up. Prolong charging can charge this. A hot laptop is a very common thing. If possible, purchase a laptop cooler from any major departmental or IT store near your location.



4. Do NOT place the laptop on your legs. It is not ergonomic and can cause excessive strain on your neck and the heat from the laptop is not at all good for your legs. It can cause a lot of unnecessary health issues in the future.



5. If you are at all unsure how to do any of the above, look up an IT friend. If none available, bring it to a nearby Computer Store. Careful they don't overcharge you for their services if you're not an IT-savvy person.



Other factors may cause the heating up as well but as mentioned above, there are too many to look at.

First you should blow out the vents of all dust build up. Make sure the fan is running properly. When using the laptop, make sure the vents don't get blocked in any way. For instance, don't lay the laptop down on the bed or sofa or anything soft that lets the laptop sink down enough to block the vents. You may want to get a cooler to set the laptop on. This will blow more air to the laptop. Overheating can cause the laptop to slow down and hopefully the laptop hasn't overheated to the point of being damaged. There are several other reasons the laptop could be running slow. It could have programs running in the background, it could have viruses, you may need to delete all the temporary internet files and/or the hard drive may be wearing out (going bad). If the hard drive is what's causing the most heat, then get prepared to replace it. I would recommend that you save any files you don't want to lose and completely wipe the hard drive clean. Do a full format and reload the operating system along with the programs you use. It may seem a little drastic, but at least this way you will be starting fresh and if any problems show up, you'll know the computer itself has issues. The best that can happen is you'll think you have a new computer again. If you are not savy enough to do this, get someone that is to help you or take it to a shop you trust. I don't recommend the "Geek Squad". Before doing all the reloading, try to determine if the hard drive is getting extremely hot. If it is, then consider putting in a new hard drive before paying someone to do all the work or you may wind up just have to do it all over again.



Update: the previous answer mentions the battery getting hot, that's a good point.

Answer 3

If it has only recently been getting hot and slow, it may be due to the heatsink separation from the CPU. Open it up, remove the heatsink/fan, clean the cpu and contact point of the heat sink with a cloth, and re-apply thermal paste.



Clean the dust off of the fan as well, and get software to control the fan speed if it still persists afterwards, and run the fan on higher rpm.



EDIT:

Don't go with what the other guy said. Hard drives are not what generates the most heat in a pc. It's the cpu that generates the most heat, or a dedicated GPU(is applicable), both of which would be cooled by a combination of heatsink and fan. You should never replace a hard drive unless it has too many bad sectors, clicks or just fails to maintain stored information.



Try running it without the battery inserted, make sure that the cpu down clocks when maximum power is not needed. Should be an option for that in BIOS, or use third-party software.

@Mike J dude wtf you computer noob! this isn't caused by a virus!



when setting it on your lap do you let the fan get some air? this could be due to several reasons, your blocking the fan so its heating up, and/or you need to buy an Air Can and blow out the dust, dust do build up in laptops and can be a laptops worst nightmare, its also super unhealthy to the computer, you can go to the store and buy these laptop cooling pads, some are cheap some are expensive depending on the brand and quality of it but those will help the computer stay cool and you probably wont get burned. also if your working the laptop more, like playing games then it could be overheating which will result in a sudden shut down, no worries nothing should be damaged.

Hope this helps and you get this resolved ASAP!

Answer 5

contraptions that are skinny tend to get heated up! The have much less ability to hold air, as a result lowering ventilation. many times in case of laptops getting heated, it relies upon on the utilization. whilst the CPU utilization is extremely intense, the failings get heated up. there is no longer something to tension approximately. purely make certain that perfect air stream takes place. There are additionally computing device cool pads attainable, you will desire to purchase considered one of those and use, it improves the air stream!.............. :) thank you for reading!

Answer 6

That's what happens when you're constantly on the computer and don't give it a rest.

Answer 7

did you ever defragment it, what about anti virus? try those first, i recommend Norton for the antivirus. also you may have dust in your system
