Slow speed, fan coming on loudly in Dell D800

Hi. When i play media on my Dell D800 (streaming video or music) it has developed a problem where the cooling fan comes on very loudly and suddenly the processor slows right down. I have to re-start to get performance speed up again. Can anyone help me?

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.

Video slow


You probably need more memory.

If you place a dvd in your drive and play it does it play slow and stall? If so you need more memory. If not then the site you are streaming the video from might be slow or have heavy traffic.

Your internet service provider might have you on a slow line speed. AT&T has different line speeds for their customers. If you purchase the lowest priced package then your line speed will be very slow on downloading and streaming.

Shows i have excellent signal but video freezes often on dell d800 laptop


Does it freeze when you play a DvD on the system? if not, Video Memory is probably not the problem. I would say your problem is probably the streaming or downloading from the site you are watching the video from. Your line speed might not be high enough (for example, AT&T sells different line speeds and the lower the speed, the slower the download). How much main memory do you have? That might be a factor too. I would say you should at least have 1 to 2GB of memory.

Hi the sound for the music player is not very loud unless you put the ear phones in ?


Hi, I have two reasons in mind why this might be;
1: The media volume on the phone may not be turned up all the way, check the Media volume and not just the ringer volume.
2: The speakers on the phone itself may not be designed to be very loud when it comes to playing music, the varying frequency ranges are difficult to pump out at loud volumes with such small speakers. Developers of the phone may have just anticipated users of the music player would always listen with headphones.
If you want a phone to play loudly without having headphones in, specify such a desire to a sales rep in a store so they can suggest the phone that meets the needs that are most important to you.
Good Luck hope this helps

Dell Latitude D800 PC - Fan-2-CPU problem


There's a second fan beneath the keyboard, you need to pry open the top panel where the power buttons are, then remove 2 screws for the keyboard to come off. When I did this, I saw the second fan with dust blocking it. I used a vaccum cleaner and my D800 works perfect again. One reason why the top left corner fan runs at full speed is that it reacts to the other fan being disabled, kind of like an emergency detour for the heatsink.
