..another newbie here
I"ve changed CPU on my laptop...from B830 to i3-3120M
I"ve got an HP650 NOTEBOOK PC, 4GB RAM, Intel HD graphics 4000, CPU i3-3120M, Windows 10 64-bit
Everytime he shuts down exactly in 30 min...
I thought it might be an heating issue..everything is ok with cooling, no problems with BIOS, all the drivers are ok..
I checked the thermal paste and it was also ok...
i tried to boot it in safe mode to see if it is an software issue..nope, it shuts down again in exactly 30 mins..
Before i upgraded my CPU i checked if it support my motherboard (precisely i chcecked what CPU does my motherboard support and i picked one that suited me the most..here is the link http://www.cpu-upgrade.com/mb-HP/650.html ), so the motherboard should be OK with it..
I"ve got an HM70..some people say it does support only sandybridge and celerons, but others say it should be ok with i-series..
I also checked my heating pipes..they are also ok..
Please help me..

OK...
I got the solution..
my motherboard is a HM70 but i3-3120M i supported only on Intel HM75 Express, Intel HM77 Express,
Intel HM76 Express and Intel QM77 Express..
So...it"s my fault of not studying enought, it was all in the motherboard...gotta look for something that support HM70

anyway, thanks for the help buddy..

I had the same problem with an old AMD processor on a desktop. Please answer these questions:

`What is the current default clock speed?
`What was your previous CPU's default clock speed?
`Are there unlockable cores and have you unlocked them?
`Is it overclocked or underclocked?
`Have you replaced ANYTHING else besides the CPU?

A lot of laptops are finicky when it comes to CPU replacement, so the more info the better. I can guess preemptively though that your laptop either doesn't like the CPU or the clock speed is too high. I would first try factory resetting the BIOS settings (at your own discretion) to see if there a conflict. Then maybe underclock the CPU (IF YOU KNOW HOW AND ARE EXPERIENCED) to whatever your previous CPU's default clock speed was and see if you can alleviate the constant shutdowns.

Have you reset to factory on the BIOS settings? Try that then try running your laptop at 1.8GHz via underclock (AGAIN, PLEASE ONLY DO THIS IF YOU ARE EXPERIENCED--). If it still shuts down after 30 mins try stepping it up .1GHz at a time til you reach 2.4.

tried to update BIOS and it didn"t work so i rolled it back..
The B830 1.80 GHz had an integrated HD graphics 2000 and the i3 has intel graphics 4000...isn"t this because of that?
Tried to underclock to 1.8 GHz..doesn"t work
Gonna try lower...but i don"t think it"s gonna work..
some people say that maybe it is an "Intel® Anti Theft BIOS recovery Timer" that is enabled and powers off the system at exactly 30 mins...but my motherboard does not support this so what the hell is wrong with Intel..
People are spending money on buying new things and then they got surprise like this...

I've been having the same issue after upgrading from a Pentium to an i7.
After I switched back to the original CPU the problem stopped.
I've been doing a lot of research and it seems that the issue is actually with the Intel Management Engine.
If you've never heard of it, don't be surprised, neither had I.
It's a subsystem on the newer (2008+) processors that performs tasks during boot-up, while the computer is running, and while it is asleep.
The Electronic Frontier Foundation (EFF) and security expert Damien Zammit accuse the ME of being a backdoor and a privacy concern.
In 2016, the me_cleaner project found that the ME's integrity verification is broken. The ME is supposed to detect that it has been tampered with, and, if this is the case, shut down the PC forcefully after 30 minutes. This prevents a compromised system from running undetected, yet allows the owner to fix the issue by flashing a valid version of the ME firmware during the grace period.

Personally, I have yet to find a way to correct this issue, even by flasing a valid version of the ME firmware, but I am still looking. I hope this helps point you in the right direction.
