Dell Inspiron 5721 :: Fan Never Shuts Off?
Mar 1, 2013
I recently purchased a Inspiron 5721. The fan comes on about a minute after it boots and never shuts off. Very irritating. I updated the BIOS to A05 but it didn't make any difference.

I put the sims 3 in the computer, it loads to the main screen and the shuts down. It doesn't give any warning and does not restart.  It also doesn't give a reason or notice as to why it shut down. The computer is not over-heating and I only have 1 expansion pack. Extra info: It is an 8GB RAM, intel core i5,  is a 64-bit operating system, and Windows 8.

I bought my Inspiron 17R in autumn 2013 with I7&1TB and after a week the fan got louder.For a certain period I though it was normal that the fan gets loud while playing games but it started to make noise even when I was watching a video or surfing on the net... I get used to it but now it makes noise from the moment I turn it on. I can´t even watch a movie without headphones because of the loud fan.Is there any way to make it stop or decrease the noise?

I have a new 5721 running ubuntu 12.04 and the fan runs full speed constantly from seconds after loging in. I am using s fraction of the CPUs' power and still the fan runs full belt and is pretty noisy. I have read that Dell computers are certified to run ubuntu, but this seems to be a problem with no solution after hours of searching the web for an answer.

I have an Inspiron 5100 That when turned on turns off after about 5 seconds. Once in a while I can get it to turn on but it blues Screens (memory Dump) after the Windows Splash screen about 80% of the time and the other 20% it runs fine. I saw this post Inspiron 5100 won't stay on for more than 10 minutes. and thought I would try Cleaning it out, The Fan turns on so its not that. I also Put new thermal Grease on the Cpu since the old stuff was dried and flaking off. This, I am sad to say, had no effect what so ever. So I Thought I would Ask the Laptop Guru's here to see if my assumption may be right. Do you think that the Proccessor is bad and needs replacing?

Whenever I play any type of game that needs a moving screen or any graphics at all, my screen will just shut off.
No sound comes out of the computer, the backlight isn't on, the screen is just dead.
I've been turning it off by taking out the battery and removing the power plug but haven't tried holding down the power button yet

My screen just shuts off sometimes. It goes black and i may or may not be able to get it working again.
Pushing buttons on the keyboard or moving the mouse does nothing, nor adjusting the display's brightness. When it goes on i can hear the "da-dam" sound that Vista makes when you connect/disconnect something to/from a USB port.
It is very annoying as you might deduce...

Recently laptop shuts down unexpectedly even when battery shows 40%. When it restarts with mains on, battery shows 0% power. When I check the battery health, it shows "Your Battery is able to charge normally. However, you may begin to notice reduced operating time because your long-term battery life is decreasing". I know my battery possibly needs to be replaced, but don't understand why battery indicating incorrectly?

At random, the 6,5, - and = keys get pressed (can be seen if a text editor/area is focused at the time) and the Windows 'help' dialog pops up, then shut down (no BSOD) within 2-3 seconds. It can also just shut off at any point during boot/shut down.

Dell inspiron n 5010. Was using it, and suddenly went off. I try putting it on, but it shuts down, every 10 seconds, whether in bios mode, diagnostic mode or booting mode. I start it and it says repair windows, enter, and it shuts down again within 10 seconds.

so my old ac adapter was starting to break..the end that plugs into the laptop was falling off..then it stopped charging the laptop...i have been using another laptop for awhile and decided to buy a new ac adapter for my 5100...well i got my adapter today and plugged it in..the 5100 powered on and i turned away for a second and looked back and the screen had a bunch of words and the only thing i caught at the bottom it said press f2 then it shut off...so i tried to power it back on and it went to the dell intro screen where u can press f2 and then it shuts off...everything turns on the fan and the screen comes up but as soon as it gets to the dell screen it turns off..
When i tried powering on again the lights flashed and nothing turned on..i unplugged the adapter and plugged it back in and the lights flashed as i did that...i pushed power and it started up again only to turn off at the dell screen..as the adapter is plugged in the battery light doesnt stay on at all..just flashes when u plug in the adapter...the light stays on when u turn on the computer but everything just dies within a few seconds..i tried pressing f2 before the computer shut off but it still just turns off

I have problem with my dell 1525. After a full battery discharge, I plugged the power and tried to turn it on. All the lights turn on, but after a second it goes silent and I cannot see anything on the screen even the dell logo.
I also tried to remove the battery and the power cord, pressed the power button for 30sec, doesn't work.Later today I will try to remove the RAM and then install it one by one to see if the problem may be caused by bad RAM , but I doubt that this is the solution.Â

I have a Dell Inspiron 1545. When I turn the laptop on the fan and noises all started but the screen stays black and it completely shuts down. Does not restart itself but shuts down.
I have tried...
- Taking out HDD

I also have another one of the same laptops and tried using the battery, adapter and hdd. All 3 worked for the other laptop but not this one.

Inspiron 9400 battery good but shuts down
Worked fine on AC or battery until I installed a new Dell battery a few months ago.
Subsequently, works only about two minutes on battery, then completely shuts down without warning and can't be re-started until re-connected to AC power. Adjusting Power Schemes "Running on batteries" in Power Options Properties hasn't helped.
Works OK on AC.

My dell inspiron 5520 beeps when I turn it on. It is a series of 4 beeps, 4 beeps and 3 beeps. It shut's down when it's on the battery. When I have it on the mains power after the first three series of beeps it shuts down but 15 seconds later it reboots and continues the beeping, this time it is 4 beeps, 4 beeps, 4 beeps constantly until I turn off the mains supply.
They are short beeps, lasting  for 2 seconds for the 4 beeps. The gap between the series of beeps is also 2 seconds. Recently it has been left in a room that has no heating and it has been quite cold lately, if that has any effect on it.

Dell inspiron N5010 laptop. When ever I carry my laptop to some place lets say from home to college it stops booting, when I switch on my laptop it starts but after 10-15 seconds it shuts off, also when I try to keep the system in bios it again shuts off within 10-15 seconds.
Twist in the problem is that if I keep my laptop idle for 20-30 minutes it starts working fine (I never remove battery or ram just left my laptop idle)
Another thing is i face this problem only when laptop is carried by me in my back pack or u can say when laptop is subjected to movement.
I noticed this pattern seriously. For past 15 days I didn't displaced my laptop from my desk and it work like any normal laptop but today when I took it to my friends place and there when I tried to boot it it starts and shuts off within 15 seconds while booting so I did the same left it idle without even removing ram or battery or charger for 10 -15 minutes and then it starts working fine.
Why is this happening is there is a problem i hardware or just some loose connection.

I have a Dell 17R 5721 Windows 8. I updated the Dell Quickset app, Digital Delivery app and the Realtek Audio Hi Def driver. Now I see that my Waves Maxx Audio 4 function is missing and F11 and F12 aren't working to increase/decrease volume. I've found several related posts, but for different computers, so they don't work for me. how to restore things back to the original factory condition?

Long time no see! I'm about to grab a Inspiron 1521 for $100, the problem is in the title. Run's fine, for a half an hour then shuts off.
My assumption is the maximum problems could be:
- Fans not working, resulting in an overheating: hence shutdown at max temp.
- Heatsinks or thermal compound issues, resulting in an overheating: hence shutdown at max temp.
- Rare possibility that it has a cold solder somewhere located in the mobo: hence shutdown after 30 minutes of running, generated heat build up .....

I chose a Dell Inspiron and believe the model is 15R although I can't be sure as I cannot remember exactly which one I chose to begin with and just checked my Dell boxes and all I saw was 'P17F', so I don't know if that's the model haha! But anyway..
Ever since I got my laptop to begin with there was the occasional time where it would switch off randomly. At first I found no reason for it and thought it might just be me and that I need to be a little more careful with it. Then it became more frequent and I noticed that it's when I move my laptop. I had it on my lap one day, I pulled my laptop a little closer to me as I was reading, and it shut down. I turned it on again and all was fine but now, 15 months on it's becoming a daily problem. I have checked the bottom of my laptop and see nothing that could be causing it. It is at the point now where small things such as tilting the screen back (and my laptop moves), setting my laptop on a cushion even the tiniest movements can cause it to switch off.
Just a minute a go, I put my sofa recliner up and it shut down as it was resting on my lap. I turned it on again, moved my leg slightly and it went again. I put it on a cushion because sometimes that works, it shut down again. I moved my laptop slightly to position it on the cushion better, went AGAIN. Then I tilted the screen back ever so slightly, it went again. I'm wondering if it's just the battery, as my battery only lasts for two hours unplugged when at first it lasted for five, then went down to three, and now two.

My Inspiron 1545 use to randomly shuts down (direct shutdown), I think i was due to over heating because i could feel the bottom of the laptop get really hot, so i started to have the laptop elevated for better air flow, that worked for a little while but then it would have the same problem, i have not cleaned the inside of the laptop or ever opened it, but i plan to do it to see whats going on, i don't think i have a warranty on it anymore so i think will experiment, but before i do that, i wanted to know what could be the cause of this problem, my best guess is i need to clean it or replace the CPU fan.
Also, I left my laptop in the car overnight and i was really cold out, after that night, now the laptop doesn't stay on more than 2 mins.....

My inspiron 15r 5520 is 1 year old and now it shuts down suddenly when doing slightly stressful tasks like playing games ,which i didn't encounter in the starting months.
But from week whenever i play a game it shuts down in 10 min .Later i tried few suggestions from dell forums on overheating and found that the laptop runs fine on battery and as soon i plug in the adapter it turns off in 10 min .I checked if it is a overheating problem and found the cores temp at around 60 degrees celsius when idle and it crosses 100 when i play games plugged in and around 95 degrees on battery.
I then checked if its due to dust but everything is clean and i use a cooling pad so this is quite abnormal.
I have all the updated drivers and bios, fresh installed windows again, so what to do...

My XPS 14z isn't even one year old and it feels like 3 years old because of this problem. It is always just randomly shutting down. No warning, nothing, it just cuts off. The screen goes black and when I turn it back on, its like I did a "force shut down" so I always have to select "start windows normally".  I actually started keeping a list of all the times it has shut down because it happens so often. I just like pick it up, or slightly shift the computer and bam the screen goes black. Also sometimes the laptop will shut down and wont even turn back on until I plug in the power cord! I am tired of the laptop shutting down in the middle of something important!

I have just bought a new game - dawn of war 2.
Approx 30 mins into the game the laptop just shuts down, no BSOD, just powers off. When i reboot it there is no system error saying it was a major crash or any warning telling me why.....
I have installed a heat program to record the heat on teh GPU and the CPU, at the point of crash the GPU is around 85 degrees C.
I have taken the back off the laptop and cleaned the Heatsink fan, it was pretty dusty.

I've recently starting playing Civilization 4: Beyond the Sword again, and my computer (stats listed in my signature) has started to shut down, I'm presuming from overheating.
I downloaded CPUID hardware monitor and those are my web-surfing/idling temps. This bad boy can get very hot. I only just realized a few moments ago that my fan does not often speed up to max.
Unfortunately, I don't have the extended Dell warranty, and since I bought this in 2007,
Will I have to take it apply and reapply thermal paste?
What utility can I use to test the fan to ensure that it's working properly?

My XPS L501X laptop shuts off completely and without warning. What happens is the cursor freezes. The computer does not respond to anything. After about 15 to 60 seconds, the screen goes black and it completely powers down in an instant. It does not restart on its own.
After it shuts down I can re-boot, but sometimes is shuts off during re-boot. Other times it runs for 5 minutes or so. Usually it acts this way for a day or two, then it's "OK" for a week or so before it starts acting up again.
I have run Dell diagnostics and found no problems. I have taken it to the local computer shop. They ran diagnostics and found nothing wrong and were not able to get it to shut down. Yet when I brought it home, it shut down on me within the first hour of use. It seems to run longer in safe mode, but I did have it shut off unexpectedly today while it was in safe mode.
I suspected there might be a problem with my video card as it seemed to be worse when I had an external monitor hooked up to it. Then I ran it for several weeks without the external monitor and it seemed to be OK. Until today when it started shutting down again with no external monitor attached.
This has been an excellent computer until this started happening about 6 months ago. I"m on the verge of giving up and buying a desktop (another laptop like this one is just too expensive). My laptop is out of warranty.

However, a problem appeared recently: the laptop seems to overheat and it shuts down automatically when the temperature rises a lot. I installed SpeedFan to check it and see whether it is abnormally high. Sometimes it reaches about 80-90 degrees on the 4 cores and the hard disk. Slightly before it started shutting down, the fan became very loud and it switches on and off continuously. So I don't know where the problem started.
