A hot laptop underneath is normal as long as the laptop is not turning itself off. Also a hot AC Adapter is normal. Some barnds of laptops and chargers (AC Adapters) get hot but if the laptop is functioning don't worry about it.
You can buy a Laptop Cooling Fan which plugs into the USB Port. The laptop sits on top of it and it has fans which help keep the bottom cool. You can get one for less than $20 at:
When the site comes up just put in the white search box at the top of the web page: Laptop Cooling Fan and press GO. When the results are returned you can filter them by Price Low to High.
The link below shows one that I've used to diagnose if a laptop is over heating. The laptop was constantly cutting off unless I would sit it on the cooling fan.
To avoid overheating and graphics card buring out, use the laptop keeping on a flat surface, especially not on pillows, bed and lap. Also dont use the laptop always connected to the power adapted. Connect only when the battery goes down. This will increase the battery life too.
About the speakers, you need to replace them with factory OEM speakers.
The touchpad and the headphone outlet will get hot if the laptop is hot inside. You might want to check the fan for dust and clean it. So the heatfan extracts the heat from inside. Avoid using your laptop on a surface without airflow, such as mattresses or pillows.
Typically, normal temperature is over 100 degrees. There have been reports of fires starting as the result of a overheated PC. I am not making the claim, I have not had this experience.
Heat is the enemy of delicate computer parts. They call them Lap Tops but you should never use one on your lap. Always place your lap top on a hard surface to insure the vents are not blocked and the internal fan can try to do its job. If you are concerned about the heat, you can get a 'cool pad' to use under your lap top. A cool pad has a fan which blows onto your lap top to keep it cool. The cool pad gets its power from a USB in your laptop. This cool pad should not be used for long periods of time on battery power for obvious reasons.
Laptop Processors do rum hot. There have been reports of people burning their legs because the exhaust is around 70 degrees Celcius when working hard. Ensure that the air flow is not restricted and the hot air can exhaust easily from the grille/vent. If the fan runs at high speed all of the time, it probably needs cleaning out. Use a vacuum cleaner and with its pipe, place it over the air inlet grille/vent while the laptop is switched off. That will clear most debris from the fan blades. Hope this helps.
is this computer under warantee being new? if so contact dell for service..
this is usually a telltale sign of processor overheating.
unplug it from the wall and let it cool for 30 minutes. restart it, make sure your not laying it on a blank, your lap, or any other surface that will block the vents on the side bottom or rear. I always put mine on the table or a book, any flat hard surface is good.
if it still shuts down after a few mnutes , i would contact dell warantee support.
This usually happens when your laptops gets overheated. Avoid using laptop keping on beds, pillows of laps. Always keep it on a flat surface facilitating amble air flo. Also dont use the laptop always plugged to the power adapter. It again overheats the base. Change and discharge the batteries, this increased the battery life too.
Using a laptop on your lap is probably the worst place to use it. Most laptops have air intakes underneath or the side. Put it on your lap and these air vents can get blocked or restricted by you clothes. A solid surface is much better. Placing the laptop on a bed or pillow has pretty much the same result for exactly the same reason. If you plan to use this on your lap, find a cheap laptop cooler to set it on and I bet the problem goes away.
Keep it cool. Despite its name, you lap is not the best place to put a laptop. Laptops generate a lot of heat, which can have a severe effect on your laptop's performance. Try not to use it in a hot room. Never set it on a bed, pillow, upholstery or anything else that is soft. Instead, place your laptop on a hard surface like a table. If you like using your laptop in bed or on the couch, try putting a book or a thick magazine in your lap and then setting the laptop on top of that. Every ten minutes or so, turn the book over so the surface never gets too hot. This will absorb the heat.
Step2Shut down unneeded programs before using power-hungry software like games or large spreadsheets. The more programs you have running at the same time, the worse your computer's performance will be. Most computers have a lot of unneeded programs running in the background from the moment you boot up your computer. Shut them down manually using Ctrl+Alt+Delete, or download a freeware application that will shut them down for you. If you have Wndows Vista, you can also access the start up configuration by selecting "Run" from the accessories menu, then typing "msconfig" in the box
