No, you cannot upgrade from an i5 2450M to an i7 3540M.

It's better to have a portable setup instead of spending on a full PC right now.
I didn’t locate it precisely. The nearest match is an i5 CPU but it seems to have an AMD Phenom graphics card, which likely isn’t available. It might have been refurbished. I’ve looked into CPU swaps and everything looks compatible except for the BIOS and power requirements, which I’m still working through. The same chipset is present, but details about BIOS or power are still unclear.
Yes, without a better cooler it will get too hot. Only if it can handle the heat will it work.
Verify the chipset. A 6x model means Ivy won’t work. A 7x should handle Ivy as long as HP hasn’t made any BIOS changes. Avoid switching to a 45 W TDP chip—most boards won’t accept them, even with a 35 W cTDP option. The HD4000 offers little improvement over the HD3000. It won’t perform well with 3D games, even for older titles. The i7-3632QM could be a quad-core choice (though graphics will lag compared to the 3540M). I’ve used this in a Toshiba laptop (originally i3-3120M) successfully. In short, don’t upgrade unless the chip is free—then give it a try.
Confirmed. I recall upgrading my 12-year-old Asus K53 from a Celeron B800 to an i5-2430M without any problems. My old Compaq from the same time had a socketed CPU as well. As others say, it really depends on the chipset and BIOS support. Even if the chipset is compatible, some manufacturers still restrict BIOS updates for the CPUs they shipped with. You might want to reach out to HP, but chances are they won’t have details anymore since it’s quite old. Also, the cooler might struggle with an i7 upgrade. Upgrading won’t turn it into a solid gaming machine. With a few mods like Sodium, Minecraft might run around 40 FPS, but the system remains too outdated for anything beyond basic browsing. Probably worth selling and investing in a newer model with a 6th generation CPU instead. TLDR: it could work, but not reliably, and it won’t be great for performance.
