Laptop CPU Upgrade?

I know some laptops have the CPU soldered to the motherboard, but I have been checking my Maintenance and Service Guide for my HP Pavilion dv7-6b55dxand it says that it has other cpus on their for other DV7 model numbers, But I was wondering if I could but a CPU that it says on the list and use it in my laptop. The big problem would be battery power I think.

  • 65W AC adapter
  • 9-cell 100WHr lithium-ion battery

Is that good enough?^

I mean I could go for the same 35W CPU as mine which is a i5-2430M

Is it possible? and would you guys recomend me doing it? I really need help. Buying a desktop isn't really a option right now.

The biggest problem would be cooling, you can't go over the rated TDP of your laptop because the CPU cooler is calculated just for that value and can't handle anything with a greater TDP.

You can change the CPU normally, the typical socket has a screw to lock the CPU instead of a lever. The mainboard has to be compatible though, most of the time laptop mainboards are very limited. If the CPU isn't broken, I wouldn't change it.

maybe, take a look at dissasembally videos on youtube first too see if it's actually possible but dont expect the video to be a relaible guide to do it correctly. also even if you can, it's no walk in the park. notebooks are a sod for taking apart and putting back togeather, i can not stress enough you have to be methodical and make sure you have a way of keeping track of what your doing every step of the way. iv done a few notebooks myself for clean outs, resetting new TIM, and one or two cpu replacements. from past exeprerience it's not easy. 

I absolutely despise disassembly of notebooks.

insane, dont do anytihng like this, clean, wipe off laptop then sell it while it is still useable and buy a new one. 

Inserting a new CPU is possible if you have socket that it will fit into , U need to check what CPU you can fit into motherboard by socket type - then what freq. it can handle and what Voltage and power drain can be done, the other tihng is that all other components on motherboard are fitted to work awsomely with your current CPU, if you will insert something else that may work - even not frying up entire board but I suppose it will be slower because of other components will not handle that anyway.. in nowadays mostly in laptops there are mutliple software overriding and overclocking already made by producers, you will lose it while installing sometihng else aswell..

Also remmember that even if you will put in a faster CPU it will not get more voltage so freq will be lowe than it should be , exaple I have dual core 1.74Ghz, I checked that i can put into maximum 2.3 Ghz.. but if I will do .. it will be downgraded back to someting like 1.84  which is not giving really much more than what was before..

Also CPU is not everytihng, mostly GPU is doing the job.

My advice here is :
- clean all dust and such each month

- buy better and more RAM

- overclock GPU with software depending on brand- I have Ati radeon that i am overclocking using software 'ati tray tools' while overclocking dont push too much, just do a bit by bit and see if there are no artifacts lower it a bit back down. mine is right now : core573 memory945 was 480, 800 . So it is not much but still i have 40fps with skype in LeageofLegends on 6years old laptop. 

cheers

ps.

fan is not a problem you can override it using proper software and proper drivers, use google 

For such a laptop it is most likely an embedded option, but I can't find the actual product number for the processor which would give more information. Also, having looked at the spec list for the laptop, I would recommend not attempting any upgrades on it as they would certainly not give enough performance for the money. Core i5 chips, even 2nd gen mobile chips aren't particularly inexpensive and disassembling a laptop is a tedious task where screws seem to magically appear even when you think that you have replaced all of the ones you took out. I would have to agree with Piotr Sitko and say that upgrading to a new laptop is the better option. Maybe go with a Gateway or an Asus as those brands typically have dedicated graphics which will give you a much better performance gain. (Also, if you get another 17.3" laptop, consider purchasing a HDD caddy for it and installing a 64 GB or larger SSD into it for your operating system. Doing so will give you a huge boost in responsiveness for the operating system. Alternately to that, most Intel boards will use a system either called Intel Smart Cache or Intel Smart Response, which uses the SSD to cache commonly used things like the OS and other programs and files while still keeping the full original copies backed up onto the HDD.)

Thanks for all the info. I won't do it now, I had my doubts too. I don't really need to buy a new laptop, This one is still going strong, it also has a 2 hard drive bay with caddy but no cable. So I will maybe get a ssd soon after my second monitor im getting.

Thanks a lot!
