J130EA CPU Upgrade Intel Core i7-4700MQ (2.4 GHz, 6 MB cache, 4 cores)

[clfurness]

Hi I bought my laptop in 2014 and thought it was a j053ea , as this is what the PC World receipt stated.

However removing the battery revealed that this is infact a j130ea. I'm not sure if there are any differences at all, but i believe the current processor is the Intel Core i7-4700MQ (2.4 GHz, 6 MB cache, 4 cores).

I've upgraded to a SSD and 16Gb of RAM over the stock notebook.

I've had some overheating issues recently and will be removing the fan.

I beleive an upgraded CPU might give me better performance but I'm not sure what processors are compatible with this model.

Please advise,

Thanks,

Connor

Here is the Service Manual:

The CPU is socketed and removeable. You can upgrade as far as an i7-4900MQ. .4 ghz faster clock speed and more cache so should be a significant upgrade. The fan and heatsink will be the same. Get some tutorial help in applying the thermal compound correctly and clean everything inside real well as obviously a more powerful processor means even more heat. Good luck.

Post back with any more questions and please accept as solution if this is the info you needed.

Thanks, this is a great responce.

Given that the laptop has been overheating and crashing when hot and is knocked (emmiting a warbling/screeching sound from the speakers) would you advise me to consider trying a new processor, or is this completely unrelated?

So far I've invested in the basics like removing the old fan, cleaning the system and fitting a new fan.

When that overheating starts happening its generally a real subtle problem with the motherboard....one of the capacitors is just not working right so installing a new more powerful processor is only likely to make it worse. Then again, it can be a subtle issue with the CPU itself but that is many times less common.

Thanks for the advice - I'll see how I get on with the new fan and clean out!
