Dell Inspiron 3521 :: Suddenly Slowed Down After Working Fine For 30 Minutes To One Hour
Oct 31, 2014
My laptop (Dell Inspiron 15 3521 model) was working fine until this week. It suddenly slowed down.
Once I turn it on, it works fine but after 30 mins - 1hr, it begins to slow down. While I type words on my keyboard, it would take a minute or so for them to appear on screen in MS Word. My browser would also slow down in loading. When I try to close programs, they would go "NOT RESPONDING" and when I try to open programs, it would take minutes for them to open up. I also tried plugging in a flash drive and the laptop took 3 minutes to recognize it.
What caused this sudden slow down? Is it because of an update? Or does my computer need repair? I've only used it for 7 months.

I have an acer aspire 5750z computer, a while back my wifi suddenly stopped working, but the ethernet is fine. I've searched the internet and tried to install the required driver (Atheros), but when I try it says that the "drive might have been ejected please reinsert it now" or something along those lines. When I go to the driver manager the wifi driver isn't even listed under network adapters, oonly the ethernet drver was there. I've heard that if your computer has had a virus or if you had dropped it the wifi card might have been damaged and I wanted to know if that's true, and if so can I buy a new wifi card?

I have a new Inspiron 15 (3521) running Windows 8.
I'm using it as a desktop replacement, so it's got an external keyboard/mouse/monitor plugged in, it's plugged into AC power, and I keep the lid closed.
I have the Windows power management set up so that if the laptop is on AC power, it should never go to sleep. I also have it so that if the lid is closed, nothing should happens.
So here's the problem: If I manually tell Windows to sleep, after I wake it up again, it'll go back to sleep on its own after 2 minutes of no activity. It'll keep doing that, until I open the lid and close it again, and then there won't be any problem until the next time I manually put Windows to sleep again. I can reproduce the problem every time. I'm not sure why it does this, or why it chooses 2 minutes of idle time before sleeping.
I've got the most recent BIOS and all the latest drivers from Dell.
Is this a known bug? Or is there something I'm missing? I couldn't find anything else in the Windows power management control panel, nor in the Intel graphics settings utility.

Model: KD1A99UA#ABA
Operating System: Windows 7
When I restart my computer, my sound works for an hour or two and then suddenly shuts off. It does this with or without headphones. It works again as soon as I restart the computer, but I'd really love not to have to restart my computer every hour just to get the sound to work.
Also- downloading Windows 8 isn't an option as a lot of my work is incompatible with windows 8.

My problem is that my audio shuts off after a few minutes, then if I want it back I have to restart the PC and it appears fine, but imagine having to restart your computer after initially powering up EVERY time you want to use the PC. The Support assistant says my drivers are up to date which may be the problem due to the fact that I did not have this issue until recently which tells me that one of the automatic updates caused this problem.
Additionally, a problem that was never fixed was that my internet inexplicably drops for no apparent reason. Sporadic problem and has nothing to do with my connection as it as occurred in multiple physical locations. Opening up Internet explorer and clicking "fix connection" works after a few minutes, but this is only a bandaid solution.

My touchpad doesn't work but the buttons are working fine. It also clicks randomly (not with the left or right mouse buttons) so I have to disable it. I have installed the latest version of the Synaptic driver and the problem still persists. I think only the touchpad is having a problem because when I use a wireless mouse, it works fine.

I recently bought a Dell Inspiron 3520 the wifi was working fine, and then it all of a sudden stopped. I already went and bought a new router, and tried using my Ethernet cable. The new router hasn't changed it but i can connect to my LAN network with the Ethernet cable. I am not satisfied with the LAN network because I bought a laptop so i could use it all of the house. I will not purchase anything else because i already bought an 85 dollar Belkin router.

I ordered Dell Inspiron 15 3521 (with Intel Celeron 1007U) online when the website said this has optical touchscreen capabilities. But when I got it (2 days ago), the touchscreen is not working and I don't think it was installed on the laptop. Will Dell exchange the laptop for the tochscreen free of charge?

i purchased a dell Inspiron 3521 in July 2013 and i encountered this problem When i push the power button, the only thing i get is the power LED which is illuminated without blinking.... I waited for a while but it changes nothing the only way i can switch the power LED off is by removing the battery.... Holding the power button for a few seconds doesn't switch it off... Also when i plug the power adapter without battery, i can see the power adapter LED also lighting....No fan spins, no HDD light. Tried with Other new universal adapter and new battery. Not working.

I recently purchased a stock-standard Inspiron 3521 Touch running windows 8.
The touchscreen worked for the first few days but has subsequently stopped working which I suspect is due to windows/other software updates.
The system is not showing/recognising any Tablet and Pen hardware/drivers.

After working perfectly fine for a couple of hours the other day my laptop suddenly shut down. Since then it hasn't worked for longer than 15-20 minutes without shutting down suddenly. I dont think its overheating as it never feels very hot. Ive tried unplugging it, taking out the battery and holding down the power button for thirty seconds but that achieved nothing. I went in f12 upon bootup and tried running a diagnostics test but the laptop shut down again halfway through.

I have dell inspiron 15R, 1TB HDD, i7 processor, windows 8.1. My C drive has 500GB(approx) memory out of which 200GB(approx) is free
It used to work fast but suddenly it became very slow. I tried restarting , it got shut down but was unable to start. So I ran diagnostic test which gave an error in hard disk with error code :2000-0142. The next morning I ran the diagnostic test again and it ran successfully without any error.
I formatted it from my recovery disk and it took me almost whole night as the formatting process was also very slow. My laptop still works very slow. It takes almost 15mins for start-up and my applications are also opening too slow.

After connecting to the internet on my laptop(Dell inspiron 1525, Windows Vista), the internet connection will work great for 5 minutes or less than it slows down drastically or essentially not working at all. If I disconnect and reconnect it will work again but just for a short amount of time. The wireless connection works great on other laptops, tablets and mobile. I have Mcafee antivirus, and it could not detect any malware or viruses. Tried restoring the computer to factory settings and the internet stays connected for what seem a few minutes longer.

i was just wondering about a couple of things about my d630 and see if i am out to lunch or is there something wrong with my laptop?
1. The Fan, the fan seems to run on full throttle all of the time. i used to have d800 and it will never did that. Its not like it does it when its hot or needs power, but the fan runs at full speed all of the time? is this ok?
2. Battery life - may be due to the fan, but my regular cell battery only lasts about an hour or an hour or 15 max? is this normal .....

The touchpad on my Inspiron 15z freezes-up a few times a day; the cursor suddenly won't respond and buttons stop working. Restarting the machine usually fixes the problem, until the next time...

For a while now, my wireless has been cutting in and out and sometimes takes about a half hour to an hour to be able to connect again. Other laptops in the house connect to the same internet connection just fine. I met a girl last night who was saying how her internet wont connect anymore and she had the same laptop as me so I'm assuming its the computer and not the internet.
even before this issue though, the wireless networks window, when you click on the two computers to see the different connections, it always freezes to a white window to begin with and will take up til an hour to actually show the different connections.
This problem is incredibly annoying and i just want a solid internet connection without it cutting out .

I've had my inspiron 14z for about 2 months now. From the start I've had issues with the computer crashing (blue screen). It started happening about every hour, and has now increased to about every 20 minutes. If left it will be on an- on- crash- restart loop for eternity every 20 minutes. I have tried updating drivers, I have done diagnostics at startup, not working.

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 have a new Dell Inspiron 13 7000 series laptop. I'm not sure if this is something I accidentally turned on, but I cannot figure out how to turn it off: Whenever I turn on the computer, the default voice speaks the time and date. It also speaks the time on the hour when the computer is on. I cannot figure out how to turn off the voice. I checked the Ease of Access settings and have verified that the Narrator is OFF. How to turn off the voice that reads the time?

I have an HP Pavilion g6-1d73us laptop and although my headphones work properly the speakers do not. This is a recent problem. I have tried troubleshooting with windows troubleshooter with no results. I have checked all the drivers for audio and they check out fine. I have tried driver software with no success. Windows Media Player does not work. I get an error message when I try to use it. What else can I try?

I have a HP 6t-1200 CTO Ultrabook with the Radeon HD 8750M and Intel 4000 switchable graphics.
Problem: When I am operating with Windows 8 they function normally, but upon updating to Windows 8.1 the AMD drivers fail to be able to initiate and D3D.
1. Most current driver is dated 2013-01-14
2. Generic drivers do not recognize the hardware
3. Drivers for other HD 8xxx series based HP laptops do not resolve the problem
Current workaround: Open the Catalyst Control Center and go to switchable graphics application settings under the power tab. Switch anything that uses DirectX to run in power saving mode, this will run those applications using the intel 4000 graphics which has a more current driver that works with Windows 8.1.
Solution: For now I believe that the only solution is to wait for HP and Microsoft to work together on creating a newer driver. Once that newer driver is released it should resolve the problem. The other solution is to permanently stick to Windows 8 and not update to Windows 8.1. This is a bit more difficult though since Microsoft pushes 8.1 very aggressively. There might be a way to make the notifications and automatic attempts to update stop, but I have not looked into that solution.
