Laptop CPU upgrade problem

I don't think they made any laptops that supported both the 2nd and 3rd gen CPU's. You'd need to find a faster CPU that was still in the 2nd gen for it to work.

Hello!
 

I have a Dell N5110 laptop, with i7-2630qm. I tried to upgrade my CPU to i7-3740qm wich have a same socket, but higer clock speed.
After i took the new cpu in my laptop the pc did not start. The screen was black, the fan started spining, for 2-3 sec, then stoped, and after 15 sec it started again.

I took back the 2630qm, now i could open bios, i reset the default, then i took out the battery from the motherboard, took back the 3740qm, battery back, and it still did not work, the bios did not load.

 

Do you have any idea what sould i do? 

 

(sory for my bad english....)

thats because the BIOS dosent support the chip, so even if it will just go right in, the BIOS is missing the chip from the supported chips list basically

I spent $2500 on building my PC and all i do with it is play no games atm & watch anime at 1080p(finally) watch YT and write essays...  nothing, it just sits there collecting dust...

Builds:

The Toaster Project! Northern Bee!

that higher clock speed chip could be exceeding the laptop's power budget ?

You probably need to update the BIOS while the old processor is still installed. From what I know, a lot of computers require BIOS updates before they can use later-generation processors.

I assume your laptop BIOS doesn't support that CPU


Did you already update the BIOS?

It also might not have the ability to give it the proper power delivery, upgrading laptops is generally not recommended unless you're 100% it'll work.

I edit my posts a lot, Twitter is @LordStreetguru just don't ask PC questions there mostly...

What is your budget/country for your new PC?

 

what monitor resolution/refresh rate?

 

What games or other software do you need to run?
