Hello, Pete.

It's unusual that the laptop wouldn't power on after being used only 5 times.

One question I have - it is still under warranty ? Laptops are covered for a minimum of 1 year. If still under warranty, contact the manufacturer for repair or replacement.

Since you put it away, especially if the laptop was not in a case, there could be a lot of dust collected. Could it have been damaged in storage ? Remove the bottom of the laptop that covers the fan and remove the dust with a PC vacuum.

My other thought is that the power adapter/cord or power jack is faulty. Check to see if the power adapter cable is bent or frayed.

If you move/wiggle the power adapter at the point where it connects to the laptop, and the power goes off and on, the power jack is the problem.
The power jack is inside the laptop and could need soldering or replacement.

Hope this helps.

Carrier electric furnace (air handler) stopped running


The 5 amp fuse may be bad, they go quite often, and they are exactly the same as the car ones. Check the fuse with a meter. If its OK turn the unit on and check for voltage going to the blower fan. You should get a reading between at least one pair of wires. The unit should have a schematic on it somewhere, check it to see which wire pairs are used for the variable speeds of the fan.

Toshiba Satellite M30 Problem


Power adapters fail because of power spikes. You can do a preliminary test of your system's adapter by plugging it into your notebook and checking to see if the computer indicates that its battery is charging. Usually there's an LED (light-emitting diode) that flashes when the battery is charging. If you can't test the power supply using this method, take your notebook computer to a technician who can test the adapter.

How to keep your laptop clean and cool.


The most important part of your laptop that needs to be clean is... the heatsink. Yes, heat is the "cause of death" for most laptops. The heat not only causes all components to expand and contract a little (as you turn it on and off), but will also reach dangerously high levels and make your laptop crash or shut down if the fan(s) and the heatsink(s) are clogged with dust.

For desktop PCs this process is somehow slower and less noticeable as there is a lot of air circulating inside the case, hopefully with both intake and exhaust fans pushing it through. Also the CPU heatsink and fan are quite bigger and more powerful. There are also fans on the power supply, on the video card and probably on the chipset, for a total count of up to six fans making sure your PC stays cool. However laptops usually have just one or two smaller fans that have to do it all.

I would suggest a little experiment. Look around you for a lamp with an ordinary 100W light bulb. Now turn it on for five minutes and hold your hand about an inch away from it (be careful not to touch the bulb, it will scorch you!). Do you feel it? Yes, that is the heat generated inside that shiny new powerful laptop you just bought.

The cure? It's easy: get yourself a can of compressed air and blow away the dust off the fan and heatsink. This has to be done every couple of months or after about 50 - 60 days of using your laptop. The compressed air is quite handy for the keyboard too, blowing away all the debris from between the keys. This is not a very well known fact, but it is the most important part of maintaining your laptop.

However if the heatsink has already been clogged, this won't help. The compressed air will not be enough to unclog it. If you have never cleaned the heatsink and you had used your laptop for over a year, chances are that both the fan and the heatsink are clogged with dust and debris. The solution in this case is to remove the heatsink, clean it and install it back. This is best done in a laptop repair shop, as it takes quite a lot of experience and dexterity. One slip of the screwdriver may kill the laptop!
Some newer laptops have a special removable cover on the back for easy access to the heatsink. But most laptops have to be disassembled to reach it. Another problem is that the thermal paste between the heatsink and the CPU hardens with higher temperature, so if the laptop has been overheating, chances are that the heatsink is stuck solid to the CPU, making it very hard to remove. The process also includes removal of the old thermal paste from both the CPU and the heatsink and applying a small dab of fresh thermal paste, preferably silver filled for better heat transfer.

Another good overheating prevention is to ensure that the rubber feet on the bottom of the laptop are intact. Unfortunately they are usually just glued to the plastic and tend to fall off quite easy. They are very easy to replace and are available as spare parts for most laptops.
And lastly - don't use your laptop while it's on a soft surface, like bed cover or sofa. That will block the fan and the laptop will overheat. Try using something with a hard surface under the laptop, like a large hardcover book or a tray.

Simply put, heat is the biggest enemy of all laptops. By maintaining the cooling of your laptop at peak efficiency, you are doubling its lifespan.

Sony vaio running hot


Considering the Causes of Heat Buildup b> All laptop CPUs generate heat, and all Sony laptops are outfitted with small fans that expel this heat, preventing a thermal buildup from damaging sensitive parts. When a computer does overheat, the cause is almost always that the fan was either not running at all or was being impeded. The common situations that can lead to these problems are more diverse, however. The following sections detail possible causes and the ways in which you can avoid overheating. b> Checking and Clearing the Vents As the fan in a Sony laptop expels hot air, it expels dust along with it. Over time, dust particles may build up along the plastic vents that encase the fan. Thick dust can restrict airflow, causing excess heat buildup inside the computer and, potentially, overheating. Maintain the vents by cleaning them periodically with a small vacuum and a compressed air canister. If the vent is very dirty, the excess dust and dirt should first be vacuumed off with a small electronics vacuum or with the smallest wand attachment of a carpet vacuum. When only light dust remains, this can be cleared away with a few bursts of air from a compressed air-dusting canister, available at most computer and office supply stores. b> Checking Fan Functionality With the vents clear, you should be able to see and hear the fan running inside. Turn the computer on and look into the vents. If you cannot see the fan, put your ear to the vent to see if you can hear it. If you see or hear the fan running, the overheating was probably caused by dusty vents or one of the other issues described below. If you see or hear that the fan is not working, then the inactive fan is almost certainly the cause of the overheating. The cause of the broken fan can be one of two things. The fan could have experienced a mechanical failure. If it is under warranty, Sony should be contacted immediately about the problem. It can determine if the fan failed, and can replace it without rendering your warranty void. Otherwise, the laptop should be taken in for repairs at a shop that is authorized to work on Sony laptops. Another potential problem could be with the system software that controls the fan. If your laptop is brand new, this could easily be the real issue. If overheating began shortly after installing a new operating system, editing the system registry or installing other software, it could be that the fan regulating software was affected. If your computer began overheating out of the blue and no major changes were recently made, this is not likely to be the cause. Reinstalling the operating system or reformatting the hard disks, while drastic, can typically correct issues of this type. b> Evaluating Environmental Heat If you use a Sony laptop in an exceptionally warm environment, you may experience overheating. High environmental heat will eventually take its toll on the exhaust fan's ability to effectively expel heat. If you've been in a warm room every time your laptop has overheated, this is probably contributing to the problem, if not causing it altogether. Avoid using Sony laptops in direct sunlight on hot days, in hot vehicles and directly next to or on top of heat sources. b> Checking for Other Obstructions b> Since laptops can go anywhere, they're often used on a variety of surfaces, laps included. Sometimes these surfaces can actually obstruct the fan vents. A laptop balanced on a lap may overheat if the knee is placed directly under the vents; the same may happen if the laptop is used on a pillow, towel, bed or blanket. Some retailers sell decorative laptop covers that can block the vents and help trap heat in laptops. These should generally be avoided, or should at least be removed before turning on the computer.
Over time, dust builds up within the blades of the fan and the copper heat sinks that distribute the air. This causes the the computer to heat even faster. To keep this from happening, clean the fans in your laptop regularly so they will cool it down faster. WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL. http://www.kitchentablecomputers.com/static.php - rules Only work inside the computer case when the power has been switched off and disconnected. Never open the power source. Some of the below steps recommend removing physical parts within the computer.

Remove the screws very carefully so as not to lose them, especially anywhere within the laptop's interior. Wipe or blow away all dust collected on the fan blades and the fan's copper heat sinks. Compressed air will work best as long as you don't send the dust anywhere else within the laptop's interior. If you don't have a compressed air blower, wipe away the dust with a cotton swab.

Overheating


Like all computers and laptops, the electronic components within your HP G60 generate heat during operation.


Due to the cramped nature of laptop cases, this heat can build up quickly, resulting in possible operational and functionality problems with your G60.


Although there is little you can do to reduce the amount of heat the G60 produces as you use it, there are measures that will help prevent overheating and the subsequent damage it can do to your system.


Symptoms


When your G60 overheats, it exposes the delicate internal electronics to higher temperatures than are considered safe by the manufacturer.


Prolonged exposure to high temperatures could cause your components, circuit boards and wires to warp or even melt, as well as increase the number and frequency of system crashes and freezes.


Your G60 eventually will shutdown automatically and without warning to allow the heat inside to dissipate and prevent damage to your system.


Cooling System


Nestled inside your G60 near the component that generates the most heat, the central processing unit (or CPU), are a small fan and heat sink.


These help whisk away the heat as it's produced by passing it out of the laptop through three air vents located on the underside of the laptop.


A fourth air vent, for pulling air into the machine, sits on the back of the laptop, below the LCD monitor hinge.

Thorough Cleaning


Hair, lint and dust are all small enough to slip through or collect on the air vents, to clog the fan, heat sink and other openings.


This collection of dirt and debris greatly impacts the effectiveness of the heat dissipation of your G60 and allows the heat to build.


Use compressed air to clear the debris and dust or have a professional laptop cleaning technician thoroughly clean your laptop to encourage proper airflow.

Stay Cool


External factors can also play a role in your G60 overheating, such as placing your laptop near a heater or fireplace.


Using the machine on a soft surface such as a bedspread or pillow blocks the air vents, preventing the G60's internal fan from moving the heat inside the laptop out.


Stay away from hot environments and use your laptop only on solid surfaces.


Laptop cooling stands can provide extra help to your G60's built-in cooling system by providing an additional fan or two in a sturdy stand.


Clean the Fan on an HP Laptop


WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL.

the fan would need to be changed also it may have over heated the pump. if it has been left for a long time in this way it could of done more damage. you could be luck and that the fan might be telling the unit control its not moving so it will not turn on. but to find this out you will need to replace the fan if the fan has 3 or more wire it would have this feature.

My air handler comes on ,not the outside unit when my thermostat is in the off position even if i turn the thermostat down to 50 and have it turned off the air handler comes on for about 5 to 10 minutes...


If you have a standard thermostat the fan switch is for the air handler only. It completely over rides the thermostat for most settings. Now lets see this is what I'd expect:
fan switch on Indoor fan runs all time
Fan switch auto Indoor fan only runs when thermostat is set to cool or heat and the thermostat is turned up above room temp for heat or below room temp for cooling. In both of these modes the furnace blower comes on and stays on til the room temperature is satisfied. The outdoor unit only comes on for AC the out door unit will not come on for heat or the "on" setting on the thermostat. See exception 1 & 2 below...

Exception 1- (in a heat pump the out door unit runs in both heat and cool mode unless it has emergency heat turned on then it will not come on outside in the heat mode, and depending on the type of heat pump and furnace or air handler it is). A heat pump thermostat usually has "backup heat" and an "emergency heat" setting switch on the thermostat.
Exception 2 - On some thermostats they are made to cycle on the heat if the temperature reaches a preset temp (around 50'f usually but definitely by 40'f). This mode prevents freezing when if instance the homeowner is away or while the home is under construction. In this mode the fan inside can run but the heat usually comes on with it.
Exception3 - On some electric furnaces the heating strips may be individually controlled and thus not all come on at one time. This may give the feel of no heat especially if the room is cold.

Now there may be other exceptions but Ive tried to give you a heads up on some of the most common ones.
If you need more help please post more specifics about your unit/system as to for sure what switches are set to what setting and what is happening with each. My first though was that maybe your system is OK and you needed to know if the thermostat was working properly.

If this helpd you understand your problem would you please give me as hifgh a mark as you can. Thnaks for using fixya and good luck.

Hi - What you see is the fan that cools the main processor:

4b1bfcb.jpg

It will spin to cool the processor when it gets hot so depending on the surrounding air temperature it may not spin. Usually you can feel it spin up briefly when the machine turns on, try placing your hand over the vent when you switch on. If the laptop seems to be running hot & the fan does not spin then you need to get it looked at as overheating will cause a failure in time.

Please take a moment to rate this solution & let us know if the information given was useful to you - Good Luck!
