Windows 7: My Dell Inspiron has started stopping down unexpectedly- again

My Dell Inspiron has started stopping down unexpectedly- again

Guys please help. Actually this is a repost of an old thread of me, the problem being the same: My laptop turns off unexpectedly

The problem is the laptop shuts down unexpectedly. I took the following steps:
  • Put a cheap usb cooling pad with 3 fans inside it
  • Changed the "Maximum Processor Power" to 85% and 80% for AC power and battery respectively. I read somewhere on net that it could help the laptop from overheating, though I'm not sure now whether heat is the only problem
  • Use a electrical blower to clean the vents of the laptop
But the problem persists. Surprisingly, it happens say 8 times out of 10 times, not 10 times out of 10! This makes me think that there is barely any hardware problem, but I can't say for sure.
Possiblity of processor overload and software compatibility issue are there. In that case, please suggest solutions as many as you think might help. I use Windows 7 Home Premium 64 bit as OS, FYI.



Thank you all in advance and a Happy New Year to all Windows 7 forum members and admins.

When this happens to Dell laptops, I replace the stock thermal compound with a fresh application of Arctic Silver, after cleaning the top of the CPU and heatsink. I blow all dust and dirt off the cooling fins near the fan and run a program to run the fans at full speed at all times... It has always worked so far... I'm not affiliated with the software maker, just a satisfied customer. It's free...

I8kfanGUI - Software Informer. I8kfanGUI is a graphical Windows application to show the internal temperatures.

Questions..
  1. Does that software really work?
  2. What is its impact on other hardwares e.g. chipsets, RAM etc?
  3. My Windows says that the driver is not digitally signed. What to do for that?

The Dell Community users forums, Laptop hardware section, would be a good place to go with this. There are those there that are familiar with specific model Dell's or know of global problems in certain models. The Dell forums are also users helping users.

  1. Does that software really work? Yes, it does!
  2. What is its impact on other hardwares e.g. chipsets, RAM etc? No impact, it simply runs the fan at a desired speed...
  3. My Windows says that the driver is not digitally signed. What to do for that? Install it anyway, it's fine...
Again, I'm not affiliated with the developer of the software but Ive been using this software on all of the Dell Inspiron and Latitude laptops I've worked on (20 or so) and it's worked well on every single one...

Hi widestination,

'Unexpected shut down' could be due to a 'hardware or a software issue'. Please share the following details for more clarity:
- Does the laptop produce 'fan noise' or get overheated before shutting down?
- For approximately how long does the laptop stay on, before shutting down?
- Please observe if the laptop shuts down more often, when 'multimedia intensive applications' are in use.
- Allow the laptop to stay in 'BIOS environment' for some time to see if it still shuts down. System is free from the interference/load of 'software' in 'BIOS'. System shutting down in this mode would point at a 'hardware related issue'. To enter 'BIOS', power off the laptop > Power it back on and repeatedly tap 'F2 key' at 'Dell splash screen' (BIOS home screen appears)

I also recommend you to run 'hardware diagnostics' to check 'hardware functionality'. You may refer to this 'web article' for detailed steps on 'running diagnostics': http://dell.to/OUGnqT

If no 'hardware issue' is detected, check 'CPU usage' (If possible, check the usage when you are suspecting a 'shut down'):
- Press < Ctrl + Del + Enter > together to launch 'Task Manager' > Click 'Processes' tab and capture details of program (s) with maximum CPU usage > Click 'Performance' tab to capture details of CPU usage details

If 'processor' does not appear 'overloaded', try a 'virus-scan'. System may 'shut down' due to an infection also. You may also check the 'current status' of 'security software' in the system.

Hope this helps. Do reply with the fndings; would be glad to assist.

Hi Saurabh,

'Unexpected shut down' could be due to a 'hardware or a software issue'. Please share the following details for more clarity:

Overheated: Yes, but not always. Sometimes it shuts down on 38/39 deg cpu temp (as measured with Speedfan). Fan noise: Never had this issue. I am sure and double-checked that after your post. The fans make normal or no sound.
Quote:
- For approximately how long does the laptop stay on, before shutting down?
Approx. 20-25 seconds normally. How bad is it because I think you wanted to know the time taken by all the processes to be ended by the OS?
Quote:

Most of the time this is the case! Programs like strategic games, Adobe softwares or even a movie shuts down the laptop most of the time, but again this is the case of 90%- in 10% of time this is not the case. One more thing I'd like to mention that the ugliest enemy of my laptop is none other than Google Chrome! I use it frequently but can't figure out why the process list shows around 12-14 chrome process instances. I use Chrome with 'Process-per-tab' now but tried 'Single-process' parameter also, no use!

I tried after reading your post. No issues at all.

Used CPU-z. Will try your link now.

A screenshot is attached. Please see it. BTW, I have lowered the Max. processor Usage to 90% in the 'Balanced' power profile. Does that do any help in real? I have found no gain so far, hoping to have some gain. What do you say?

Fully checked with i) Avast 6 ii) Microsoft Security Essentials iii) Spybot -SD. Any other AV you suggest?

Please consider providing a link from where I can have the fan software, digitally signed. I searched, all were digitally unsigned. And I don't know how to install a digitally unsigned software. Thank you in advance.

Hi widestination,

Thank you for the response.

The system appears to shut down even at 'normal operating temperature'; doesn't seem like a an 'overheating issue'. Would still request you to observe the 'movement' of 'system fan'. Please double-check if the fan is functional.

I also recommend you to 'flash BIOS'. Before 'flashing the BIOS' please check the following:
- Battery should have 10% or greater charge; Adapter should be connected; No external devices should be connected; All other programs should be closed and documents saved
- Click Driver Details | Dell United States to download and install the latest BIOS
- Recheck results after the system restarts

Though it appears to be a 'software related' issue, would still like an update on the results of 'Hardware Diagnostics'.

Multiple instances of 'Google Chrome' are due to its 'multiple processes architecture'. It keeps (tabs, extensions, web apps, and plug-in) processes independent of each other.

Would also like to know if the laptop 'restarts itself' or stays 'shut down'. Would also suggest you to observe if it 'shuts down' on 'physical movement'.

'Inspiron n5010' has 2 'memory slots' (and 2 cards). You may also try to use the laptop with 1 memory chip at a time to see if that makes any difference. You may also try each card with both the 'memory slots' one by one. (This will help you isolate if 'memory slot' is the culprit). You may refer to the 'Service Manual' of 'Inspiron n5010': Documentation
Note: Please follow all safety precautions in the manual.

Hope this helps. Do reply with the findings; would be glad to assist.

The fan runs well. Checked it and no unusual behaviour was noticed.

BIOS is flashed with version you have mentioned. Can't flash BIOS twice with the same version; tried, but it said so.

Diagnosed with CPU-z and SppedFan. Please suggest any better way of h/w diagnosis.

It doesn't restart itself, it shuts down completely. Every time.

Can this happen with a problem in physical memory and/or memory slot? Is this a 'DIY' process to check the nature of memory slots, because Dell guys barely come to my area!

You asked in your early post whether this happens with multimedia-specific programs, and I said 'yes, most of the time'. So what to do with it?
