Upgrade from 3110M to 3630QM

[Excelsioris10]

Hello, I have a HP Probook 4540s notebook with an Intel 3110M processor which is a 35W part.
If I upgrade it to a 3630QM processor (45W part) are there going to be any overheating problems on long term use?
The laptop is similar to this one - http://www.ebay.com/itm/HP-Probook-...394520?hash=item1ec653b918:g:18MAAOSwhvFZBhws

Thank you in advance!

Problems? Not super-likely. In most cases, CPUs are running well below their TDP anyway, and laptop chassis will often be designed to accommodate a range of 35-45w mobile CPUs.

BUT I can't find any indication that the 4540s use anything but 35w parts, so I wouldn't be surprised if it either: 1) it overheated under heavy load*, or 2) there was a BIOS block preventing a non-listed CPU from booting.

*if you're not loading the CPU, you don't benefit from putting in a faster one.

Worth a try, if you need the speed and the place you buy the 3630QM has a return policy, but it's definitely "tinkering" and you can't guarantee results.

Several things to note:
Verify processor can actually be replaced (processor uses PGA packaging): https://www.youtube.com/results?search_query=Intel+PGA+replacement

Verify current cooling solution and power supply can handle extra power. Note: Although Intel Ivy Bridge Core i3 is rated 35 W, actual usage is lower (~15 W using Prime95 small FFT); check using hardware monitoring program such as HWiNFO. So, an i7 4-core is at least double the power of i3 (CPU-only, no significant GPU load). As for power supply, more often than not, it is not too generous in providing that much more power, and motherboards may implement a power limit.

If processor can be replaced, verify motherboard BIOS supports your desired upgrade.

I've done CPU swaps in a few laptops, including to higher TDP variants, with varying luck. I've never had problems with power or cooling (although noise can be bothersome if the cooling isn't quite up to scratch), but the BIOS not recognizing the CPU is a major risk factor. Even with models where SKUs have existed with my intended CPU, I've discovered that said SKU used a different motherboard, or similar issues. Tread carefully, and don't spend more than you're willing to lose on an upgrade.

I think the worst you will see is the fan runs on average a little faster, so more noise.

ProBook is a business laptop (sits below the Elitebooks) so your first step is looking at the service manual:
http://www.hp.com/ctg/Manual/c03758231.pdf
Under CPUs it only lists two quad cores, the i7-3632QM and the i7-3612QM. So those two have BIOS support, others may not.
