Laptop Hard Reboot
Model: HP EliteBook 745 G3
For a number of months my laptop has done what I can only describe as a hard boot. For no apparent reasons it would power cycle. No windows shutdown message, no warning, its as if somebody has come along and pulled the power cord or held down a reset button.
As this is the 2nd time its happened in less than 2 week this is really starting to cause me problems as I'm loosing work. You can see the last event 4/24/2017 on the reliability history report below.
Clicking on the view technical details reveals this snippet of information
The computer has rebooted from a bugcheck. The bugcheck was: 0x00000124 (0x0000000000000000, 0xffffe000f3f6c838, 0x0000000000000000, 0x0000000000000000). A dump was saved in: C:\WINDOWS\Minidump\050517-14718-01.dmp. Report Id: e55192e8-8d9d-45c1-8c03-e14e66640510.
Well at least windows agrees with me it was not shutdown correctly. Lets see if we can find out why.
We are going to need some additional windows tools to read that minidump
I've been keeping a log but the minidump directory has these occasions time stamped for me. As you can see this is the 8th time this has happened.
After installing the WDK we need to fire up windbg which can be found here.
Pulling the 0505 minidump into windbg this is what it tells us.

So my options are either:
- Your RAM is faulty (Bank 4 = 4th DIMM slot). Run Memtest for NO LESS than ~8 passes (several hours):
- Your motherboard is faulty, and will need to be replaced.
Either way its a hardware problem. Others reporting the same

Wonder if this is heat related as I had this set to Passive as the FAN was noisy. Probably not that would imply that this laptop would never run on batteries ! We will change it back to ACTIVE and see if that helps any and I'll put up with the FAN spinning for a while.
That did not help I'm still suffering random reboots latest happened 16-Jun-2017
This machine is being returned I cannot tolerate a computer randomly rebooting.
