HP Pavilion series is something the company really has shown off with and so far we have agreed with them. The laptop that belong to this series are elegant and powerful, stylish and expensive, However, there have been some issues regarding HP laptop Pavilion dv4 overheating.
We have read some forum posts where people complained there was a problem with the HP Pavilion dv4000 overheating, even when running normal tasks, such as anti virus applications (which may require a good amount of RAM, it’s true), the laptop would such down after 1 to 5 minutes, after some intensive fan running. The advice for such cases is to check the cooling airways to make sure they are not full of dust. The cooler is separated from the CPU by small heat pipes that run to a radiator neat the fan. This radiator’s airways may be blocked up and this causes interruptions in the CPU’s cooling process. You could try cleaning with your vacuum cleaner (be very careful not to damage any laptop parts) or buying one of those special compressed air cans and blow air through the air inlets to remove all the dust. You could also use q-tips to “squeeze” into difficult spaces. It is quite normal for some laptops to overheat when running large programs but system shutdown is something you can avoid by constantly checking for air blockage inside the laptop.
Other people have complained that the Pavilion dv4000 shuts down even when doing some file conversion or watching videos on the internet. Some solution for this problem could be swapping the RAM in a different slot and then checking you processor for overheating issues. Also, on HP’s website, you can browse and upgrade your chipset drivers (by downloading the latest ones). There are freeware programs available on the internet, which can permanently monitor you CPU temperature and that of other laptop components. These programs will start making loud noise (“Everest” goes off like some kind of alarm) to warn you when one of the parts is overheating. This may not help you much as it is not actually a solution to the HP laptop Pavilion dv4 overheating problem; it is more of a way to let you know when your fan is over-working. Other solutions are removing the batteries from the laptop when you have the possibility to keep the laptop plugged into a power outlet (this is useful because batteries produce heat when charging) and try to keep you laptop placed on a hard surface, like a table or desk because the air circulating under the laptop will do so more efficiently. When the external temperature really gets impossible (like in the summer time) you can have a regular fan that blows cool air constantly at your laptop and this may prove to be an efficient way to prevent overheating due to outside temperatures.
The HP Pavilion dv4030us also seems to be having this overheating problem and it seems that this is an issue pretty common to HP as the fans cannot handle the heat output. It’s not something you can really prevent, as these laptop models work perfectly fine when they are brand new and this problem appears after several months of usage. Another solution you might want to consider is CPU frequent scaling. This will slow down you processor clock speed when you don’t use it and it will save you battery power which leads to cooling down your laptop. You should not come across any power loss as the speed will boost you processor when you need it to. Another good fact is that it may also reduce processor speed when there are signs of overheating to avoid you laptop being shut down. This solution does not permanently remove you overheating problem, but it will prove useful when the laptop is in “idle” mode or you use it at its minimum requirements.
We wanted to check out if HP is aware of this problem so we consulted the HP Pavilion dv4 Entertainment PC “Maintenance and Service Guide”. First of all, in the manual you get a warning not to place the laptop on your lap (funny, isn’t that where you are supposed to place it since it’s a Laptop?), which keeps you protected from heat injuries. There is some other piece of advice available. It says that for proper ventilation, you need to allow a clearance on the right side of the laptop (at least 3 inches) as the fan is controlled by a temperature sensor which trigs it off when things get too heated. This may happened due to system power usage, external high temperatures, software requirements and fast battery charging. The manual also says that if you want to remove the fan and heat sink, then there are certain steps to follow. First you should shut down the laptop and disconnect all the external devices that are attached to your computer (including the power jack and mouse – if any).
After that, you need to remove the battery and all the other components, as follows: hard drive, optical drive, keyboard, keyboard cover, display assembly, top cover and system board. To remove the fan, you need to turn the system board upside down so you can have access to it and then remove the two screws that secure the fan to the system board. Then you lift the fan up and clean it good and put everything back together again. When you remove the fan, you could clean it with a soft paintbrush or fiber cloth (we believe the paintbrush is more useful though).There is also a set of instructions available in the manual if you want to replace the heat sink.
The HP Pavilion dv4 series is not the only one to have these overheating issues. Problems have also been reported with other models like HP Pavilion dv6910us or the dv2700. Be careful, if you ignore this overheating problem and keep using the laptop even though it shuts down again and again, this will only lead to the processor’s damage and you will need to replace it (because that cooling fan goes off to prevent your CPU from melting).
