Sorry to hear that! As it sounds like your hardware is passing diagnostics I would focus troubleshooting on software. Testing in safe mode and reinstalling the operating system should also help confirm this. There’s a Microsoft Fixit that should automatically push the system to Windows management, found HERE. If you’ve not already though I would suggest making sure the systems Firmware and BIOS is up to date with the latest released on the support site, Hard drive firmware updates are available from many manufactures that could have an effect on this. Dell Command Update should have installed the latest Drivers on your system but I’d suggest testing with other revision of IRST from the support site as well, this would also help rule out compatibility issues specifically with the software installed on your system.
Have you also tested different power profiles or with the system on battery as well as connected to AC?
If everything above has no effect on the locking issue at all I would suggest reinstalling the operating system. Even with the system passing hardware diagnostics, as the problem is still occurring for you in safe mode, there’s a possibility this is hardware related. Components such as memory or the hard drive could be the point of failure if the problem continues with a clean windows installation.
I can check on service and technical support options in your region if you PM me your details.
There seems to be a problem when i am trying to send you the PM. I have successfully uninstalled the IRST software and drivers and refreshed my system a couple of time yet there seems to be no effect on the problem
We have several of M4800s with this configuration in the office. Several of us had the same issue described here. We decided it must be a graphics card issue after we noticed that the external monitors were still responsive when the laptop screen was frozen. The solution that eventually worked was to uninstall the Catalyst drivers. Best of luck.
I got a replacement for the machine, and still the problem is not solved even after all the relevant updates.
I have the same problem. It's all over the internet. Dell just messed up this one up and won't fess up. I spent hours with Dell tech support twice and got the same denials. They put you off and run you through numerous procedures until you get so sick of it you just give up (so much for the warranty). I'll just live with the crashes until I can put it the trash and get a one that isn't a Dell. Until then SAVE SAVE SAVE.
Yesterday I received my laptop and I'm not very happy right now as a was when buying.
Ok so straight away I notes mouse cursor freezing every few minuts .freeze time is about 2-3 seconds.
