Re: speed reduced suddenly

Try to check the fan first. Oftentimes, the speed variation is a manifestation that the fan has accumulated to much dust. Clean it. If the problem persist try replacing it. The lack of proper ventilation inside the machine could hamper its normal routine thus slowing down the system.

My laptop won't start up normally. The fans and everything begin to turn and start when I press the power button, but within seconds, they start to slow down and eventually stop.

You did not post anything about make and model. This is kind of a guess.

My laptop has "battery saving" setting that operate the fan based on temperature. When I start up, the fan comes on and the computer checks itself, Then the fan slows down. Later when the laptop warms up, the fan speeds up. See if you have some power management scheme set that makes the fan run like this before you take it to the shop.

Your laptop should be under warranty.

Emachine 5250 2.93 cpu fan runs all the time at max speed

Go into the BIOS options and check the fan speed settings, if there is no option or way of reducing the fan speed then you will need to open the PC, vacuum out any dust, and also clear down your startup items (start-run-msconfig)

I have a acer laptop that I let my son use and I've noticed that it is very slow and also it gets very hot. What do you think the problem is?

Dear Kristen,
1. Your laptop is running slow because there are too many applications running in the background. Go through the start menu and remove them if you don't need them.
2. Defragment your hard disks. Use a tool such as O & O Defrag Pro.
3. Your Acer heating up is a normal issue. Some older acer laptops heat up quite a lot. This is not an issue in laptops purchased after 1/1/2010.
If you are worried, get your laptop checked and serviced by a qualified technician or just simply hand it over to the nearest service center.

What is the processor fan speed for Dell Vostro A860?

This could be the result of to much dirt build up in the heat sink ports blocking vital air flow. Buy a can of compressed air and blow it on fan any open ports, this should prove if the fans the issue, the speed should slow down because of increase air flow cooling the laptop. If this works the machine should be taken apart for better clean out.

What would cause my aspire 5630 to shut down sporadically?

Shut down sporadically, caused by rising temperatures on the processor (processor overheat). Processor overheat, caused by damage to the processor fan. Processor fan function to reduce the processor temperature.

Possibilities and solutions
1. The possibility of sluggish processor fan. Processor fan spins, with a low speed, so it can not reduce the processor temperature.
Solution: clean the processor fan with a vacuum cleaner, or replace the processor fan.
2. The possibility of fan processor die.
Solution: replace the processor fan.

The characteristics of damage to the processor fan
After the laptop is turned off (more than 1 hour), the laptop can turn on and survive + - 30 minutes. In the period of + - 30 minutes, the laptop died suddenly, because the processor temperature exceeds safe limits (shut down temperature).

How to check
Laptop is turned off (more than 1 hour), then turn on. Download and install software to check the processor temperature. Ex. Real Temp 3.60. See the change in temperature. If the temperature continues to rise, it can certainly cause damage to the processor fan.
- Normal temperature, when first turned on + - 38oC
- Normal temperature, after turn on for hours 40oC - 45oC
- Temperature overheat processor, when first turned on 60oC - 65oC

Hello, i have a Acer Aspire 5100 Laptop which i bought in 2007. Recently i have started having problems with HD-Ready videos (720p). before when i use-to play 720p videos on my laptop it use to run...

As you say the laptop handles the video well in the beginning, then when it runs for a few minutes it has trouble rendering the video in sync with the audio.
The reason for this problem is that 720p videos need the Graphics card in the laptop to work hard, this process generates heat and this heat needs to be removed from the laptop or the whole system does what's known as throttle down.

It slows down to reduce the heat it produces, thus preventing damage to the system.

The solution to this problem is to clean as much dust out of the laptop computer as possible, use a vacuum cleaner. Turn the laptop off and remove the battery. Clean the vents, it is a good idea to raise the back underside of the laptop with a pencil or the like. Some-thing that will raise the laptop off the work surface without obstructing the vents on the underside of the laptop. By raising the laptop it will allow for greater airflow through the laptop, therefore reducing the operating temperature of the laptop therefore making it more efficient and responsive.

Your laptop shuts itself down, this confirms that it is overheating. It does this so it does not damage itself.
If it still overheats then you will need to contact a computer technician to give it a good through cleaning. To clean the dust between the heatsink fins. Possibly increase the fan speed or replace the fan.

Take care!

The laptop fan sounds like its overworking and the laptop keeps overheating and suddenly shutting down

The heat sink may be clogged with dust and ifthe BIOS temperature sensor controls the fan speed then it may be compensatingfor the reduced cooling by the dust build-up.
If you are not using your laptop on a flat surface, it may beobstructing the cooling vents on the bottom of the laptop. Your laptop fanmay be faulty and not spinning freely, in this case replace the fan.
Check the fan and heat sink assembly and remove the dust, loosen the dust anduse a can of compressed air to clear away the dust. A laptop fanassisted cooling pad may solve your problem

2 ghz processor running at 220 mhz


Have you tried right clicking on the desktop (opening Display Properties), clicking on Screen Saver tab, Clicking the Power button, and setting the power schemes to Home/Office Desk? If its set on laptop it will reduce the processor speed when running on battery. I have noticed that even with it plugged in that some times it will run at half processor speed. Try that out.

Have a great day,

Slow speed, fan coming on loudly in Dell D800

Yeah the slowdown is the laptop throttling back due to overheating.

When you do processor-intensive work like - streaming videos - the laptop overheats. The fans come on loudly.

When the computer heats up despite the fans, the processor throttles back to relieve the heat.

When you reboot your machine, it stops performing intensive work, giving it a chance to cool down. It's not restarting that fixed the problem it's the fact that the laptop cooled down.

So here's what you do. Get an air duster and blow all the dust and gunk out from your fans. They are most likely clogged with dust and that's what's causing your cooling problems. If there are large dustballs in there, use a tweezers and pull them out. Get as much out as possible.
