XPS L501x randomly getting into sleep mode

For the last 3 months my laptop gets randomly into sleep mode.

It could happen even 10-15 seconds after switching the laptop on o 3 hours later, 10 hours later, any time.

I replaced the battery, i bought a new AC adapter.  I even cleaned every single corner inside and outside. I removed kilos of dust stacked all over the motherboard and fan. I also replaced the thermal compound and the laptop is still going to sleep mode at any time. 

I use this laptop for DJing and I had experienced the same problem while I was playing for hundreds of people. 

I am about to give up and get a brand new laptop.

Hi DJSergius,

Please click on the link below to troubleshoot random shutdown issues.

As we understand from your post, the system shuts down randomly sometimes on startup and sometimes after a few hours. We would also request you to run a hardware diagnostics on your computer to determine exact point of failure. Try entering the System Setup by tapping F2 continously on startup. Let the computer remain on this screen for some time. Does it shut down after some time when in the system setup/BIOS screen? You mentioned you have removed kilos of dust from the computer. Dust is harmful for the computer as it does not allow heat and air to pass through.

RE: XPS L501x randomly getting into sleep mode

Thank you for your answer, 

I ran different tests, hardware tests, system tests, System Mechanic, some special applications to check and record the variation of temperature. 

With reference to the dust, we are talking about the normal dust that the same fun sucks from the bottom. I mean, normal dust that it accumulates after a couple of years of use. I have never used the laptop in a dirty environment nor the beach or any other places were dust or sand could harm the laptop.

I also checked many times the Bios and I also have been playing a bit with the  Power Management. 

All the drivers have been updated.

And the laptop still goes to sleep mode at any time. 
One day I left the laptop working, playing HD videos and rendering very heavy 3D images for 12 hours and nothing happened.  
Today I turned on just to listen to some music and It went to sleeping mode 4 times.

Hi Djsergius,

Thank you for your reply.

Please update the BIOS on your Dell XPS L501X by clicking on the link below.

Click on this Youtube link for a video on how to update your Dell PC's BIOS in 99 Seconds:  http://dell.to/1fGmlNu

Follow instructions mentioned below prior to the BIOS update.

  • Ensure that the AC Adapter is connected to the computer prior to the BIOS update.
  • Disconnect any third party peripherals connected to the computer before performing BIOS update.
  • Remove any cd/dvd from the optical drive prior to the BIOS update.
  • Do not turn off the computer during the BIOS update.
  • Do not restart the computer during the BIOS update.
  • Ensure battery charge is more than 10% during BIOS update.

Note: Plug your computer to a good, working wall jack before you update the BIOS. If you experience a loss of AC power or a significant voltage sag/spike during the BIOS flash, you will either have to replace the BIOS chip or motherboard.

Please reply if you have further queries, we would be happy to help.

Thanks & regards,

RE: XPS L501x randomly getting into sleep mode

Hi, thank you for that. 

The bios was updated 2 weeks ago to A08 version and is still the same.

I switched on the laptop I pressed F12 and I ran all the tests.  The system couldn't find any problems.

The other thing I 've done is to leave the laptop on the BIOS scree for a couple of hours and everything looked fine. The laptop didn't go to sleep mode.

The other thing I noticed is that when I ran all the F12 tests the laptop didn't go to sleep mode either.  

I don't know what to do now. I need the laptop for DJing and the problem continues.

RE: XPS L501x randomly getting into sleep mode

I am starting to think that the problem should be related to Windows 7.

I've been using this laptop for more than 2 years and I never had a problem like that.

Hi DJSergius,

Thank you for your reply.

Please check the power management settings in your computer. Since the system does not shut down when in the System Setup screen, the issue could be software-related. You may try to re-format your computer in order to resolve the issue.

Back up all important data on an external storage device and reformat the computer.

RE: XPS L501x randomly getting into sleep mode

You won't believe it but one of the things that I did last week is to change the hard drive. I installed a new one and a fresh installation of Windows 7... and still with the same problem. 

Last night I was editing a video and the laptop went to Sleep Mode four times. 

That is so annoying and I cannot find the solution.

Is there any way that we could deactivate the Sleep Mode?  
What  I mean is, if the sleep mode doesn't exist what on earth the laptop or Windows 7 is going to do? Crash??? Blue screeen???

Hi DJSergius,

Thank you for your reply.

You can change the power management settings on your computer so that it does not sleep. Under Power Options, you need to select the option for "Change when the computer sleeps"  and change it to "Never". Click on the links below for screenshots and steps for doing so.

RE: XPS L501x randomly getting into sleep mode

I had this same problem. I called tech support and I must say, was transferred, disconnected, and through it all, wasted much time. 

I followed the advice on the forums here by updating my bios. That action bricked my computer. Dell unfortunately accepted no responsibility and said I was on my own. I paid a private vendor to get my computer running again and, sadly, the  "going to sleep" issue persisted (with the latest bios).  Dell support, putting it mildly, is lacking much. 

I solved the problem. 

In windows 7, go to power options. Here the last option in  the left column is "Power Smart Energy Savings."  Sounds great, right? This is what caused me over a year and a half of chronic frustration. It's appears to be a program from an outside vendor (bloatware).  I never clicked on that last option as I didn't see it as relevant. Click on it and disable it. Problem solved. 

Dell, I purchased this computer to give your company a try. My touchscreen stopped working shortly after I purchased the machine and Dell would not help me fix that problem.  Apple would never go down this shameful path. Dell could have been the Apple for PCs.  

My touchscreen will never work and I'll never get back a year and a half of Dell frustration due to my computer consistently going to sleep. It seems Dell went to sleep long before I purchased this machine. 

Sincere & disappointed,

Dave
