i have a serious issue with my Dell Precision M6500 Laptop running Windows 7 64bit.
It has a ATi FirePro 7820.
After using HWInfo v4.16-1900 64bit portable my screen got black and i had to power off my machine by holding the power button for a few seconds.
I tried to restart it, but i dont get any signal on the screen, it brightens up and i can set the brightness.
When i plug in an external monitor, i can see everything on it!
I didnt make a change in the settings, and ran with sensors only checked.
I attached the configure pages.
Can u help me?
I'm sorry for what happened, though such a problem should not happen when using any software.
As the best advice I can make is to completely power off the machine - remove the AC adapter and battery. Then wait few minutes and check back.
If that won't help, maybe a complete BIOS update could be attempted.
If neither helps, I'd suggest to RMA the part.
it is probalpy a broken mainboard. Often the nb-chip in dell laptops lose contacts.
Found someone who is able to fix that.
I just dont know how hwinfo can cause sth like that? Or was it just a very bad coincidence?
It's hard to say what might have happened, but I think it's more likely something related to the GPU.
And since the display seems to go black when GPU I2C option is enabled, one possible scenario would be that when HWiNFO scanned whether there are additional devices connected to the GPU, something went wrong in the machine. Note, that HWiNFO doesn't change anything in the system, it just performs READ commands (no write), so it's quite strange. No component should be designed such that a read request causes a problem...
