M15x work with i7 820qm?

Hi,
I purchased an i7 820qm from EBAY. I put it in my M15x. All I got was Black Screen. No Bios, No Post. What gives? Any help would be great. I put back my i5 430m and everything worked fine. Hmmm? What is happening?

 

make sure the bios is upto date firstly. then take the laptop apart and swap over the cpu's make sure you remove the memory and the bios battery which should clean all bios settings. put the laptop back together and it should work fine

 

Make sure the DIE on the CPU has no broken corners or edges. The 4 corners of the cpu die should be perfectly square and the 4 sides should be perfectly flat/straight. If there are any cracks or chunks missing then you probably have a bad cpu :/

 

I do have Bios A09. So uninstalling memory and bios should help?

 

the bios is set for the older cpu timings, so when changing cpu its always best to reset the bios and then the bios will set the correct bios settings for the new cpu and yes its always best to remove the memory also. hope all goes well for you.

 

Removing the memory is unnecessary. The rest is good though.

 

Make sure you have seated the CPU properly. I once repasted the CPU and did not reseat the CPU properly, and as a result I had black screens too.

 

I forgot to add that this is Intel Core i7 820QM 1.73 8M Q1NG ES Processor
Could this be the problem? I sent the chip back and I still waiting for the replacaemnt chip to come back to try the BIOS Reset.
They offered me another ES Q1NG 820QM Chip or an i7 720qm OEM version.
Which should I take?
ES 820 qm or OEM 720qm?

 

It doesn't need to be OEM. The i7 820QM ES Processor shouldn't give you any trouble, it may have been broken.

I'd say take the replacement 820qm and give it a shot.

 

I got my replacement chip i7 820qm ES. Installed it. Took out the memory. Took out the Bios battery. Waited 20 min. Put the memory and Bios battery back. Is this correct method? All I got was black screen again. What I'm I doing wrong.

 

The only thing I can think of is to do a power drain (remove the laptop battery, and hold down the power button for 60 seconds), remove the CMOS battery (which you have done already), make sure the new processor is seated correctly without bent pins, make sure you have the thermal paste put on correctly (just a small dab on the processor), and the heat sink put on top of the processor with it fully in contact with the processor/thermal paste.

Most likely in this case, its a problem with how you have the processor seated, or a case of a bent or missing pin. Take the processor out, and check it thoroughly for bent or missing pins. Be sure to install it correctly with all pins being seated in their respective holes. Be sure to turn the screw to have the processor locked down in the socket.

Make sure your memory is locked in the upright position too. Otherwise, I am tapped out of ideas, as you have already installed the latest BIOS.

 

Having just gone through this (possibly from the same seller as you), I can tell you that this is indeed the problem. That "ES" stands for "Engineering Sample." These chips are made to be abused, in order to find out just how much it can handle. They are not made for, and will rarely work in, consumer computers. Moreover, it isn't technically legal to sell them. Your 820QM ES will never work in your M15X, or any other laptop you get. Return it and take the OEM 720QM instead.

 

Actually the ES chips generally work fine. They are mostly used for platform validation by Intel's partners. I know people have ran ES's in m15x's before, also.

 

I agree with the above post. To say that an ES chip will never work in a M15x is well and truly false information. There are countless people using ES chips, namely the 920xm, in their M15x's (nbr members included). Its the same with anything you buy, there is always the odd chance that you may receive a bad/faulty item, or something may go wrong during installation. Worst comes to worst try for a refund/exchange with the seller/retailer you bought it from after exhausting all possible options.

 

Mine is working well with 920XM ES version..., even running on 3.0Ghz on all core

 

After all that I would suspect faulty CPU.

I also had a friend who accidentally got Thermal Paste in the socket when he installed his CPU and it messed up his system =/

 

CPU is obviously faulty, send it back.
