Hello, 

I want to upgrade my current processor, i3-4000m, to an i7-4702mq. Is it possible ?

My motherboard is a HM87, "Model 1942, KBC Version 89.10" something

Bios L74 vers. 01.07

other details- have the Intel HD 4600 onboard graphics, 4 gb RAM and an 500 GB drive with Windows 8.1 64bit.

Thanks in advance!

Here is your Service Manual:

You can upgrade as far as the i7-4702MQ so yes. Good luck. Let us know if you need any more help.

Forgot to ask, and the new processor will arrive today. 

Will I have to preemptly upgrade my bios for the upgrade to work, or can I just install the new cpu "as is" and work straight ahead ?

Thanks again!

CPU did not work. Updated bios but the CPU didn't work after that either.

There are two posibilities: either the cpu is broken, or it's simply not compatible.

 Where did you get the CPU? It should not have needed to have the BIOS updated but neither would that do any harm. Did you lock the cpu socket fully with the turn screw? Does it work with the old cpu reinstalled? The manual clearly indicates that your motherboard will support either your old or the new processor. I assume you know what you are doing and did not static shock the board or otherwise mess it up.

I just ran into this issue myself, on a 650 G1.

I wanted to swap out the 4000m for an i5 4330m. The i5 is listed as a compatible processor,  but after swapping out the processor I got 5 blinks on the keyboard, and it would not boot into BIOS. Apparently this indicates a bad system board, or other HW failure.

I tried resetting the processor a few  times, and all of the other tricks (hard reset, BIOS recovery, disconnecting the BIOS battery, etc) . No luck.  I threw the 4000m back in, and it is working fine.

Does yours boot at all? Are you getting flashing indicators on the caps lock/num lock keys?

Yes I know what I was doing, I did screw in the processor after placing it in the slot. The laptop starts just fine with my old i3-4000m processor, which just happens to be in and running right now.

The replacement processor came from a guy on the internet. I think it was second hand, do not know from what laptop it was pulled out if it was second hand, nor do I have any certainty it was in working condition either. 

After intalling the i7-4702mq and booting up the laptop, nothing happens. I think I got some blinking white light on the side for a short few seconds where the power adapter goes in. I never had an opportunity to boot into bios or anything due to nothing booting up at all.

Thanks for the replies guys!

The safest thing is to get the processor as an HP part number but I know that involves extra cost. The second best thing is to get the processor from a recognized parts house, preferably a new one. Processors probably have the highest incidence of DOA of any computer part sold on the internet.
