[REQUEST] Lenovo B590 CPU upgrade to i7

[anacondo]

Hello all,

I tried installing an Intel Core i7-3610QM CPU (spec code QC0R) to my Lenovo B590 62742BG laptop, but it wouldn't boot. I double checked everything, but as soon as I inserted my old i5-3210M CPU everything started working again. 

According to this list, my chipset (Intel HM77 Express) should support the i7-3610QM CPU: http://www.cpu-upgrade.com/mb-Intel_(chi...press.html

However, according to my laptop's hardware maintenance manual, only the following CPUs are suported:

Is it possible to add support for the Intel Core i7-3610QM (spec code QC0R) in the BIOS somehow?

Here's a backup made using Universal Backup Tookit 2.0: http://rghost.net/8htTr6m4V

BIOS version: H1ET69WW (1.12)
BIOS date: 2012-11-15
Controller version: H1EC31WW (1.11)
Model: 62742BG

Thanks in advance!

This BIOS from the Lenovo IdeaPad Y480 could be a good donor BIOS: http://rghost.net/67cYnzqFh

According to the service manual for the Y480, the i7-3610QM is supported for them:

Regarding the CPU spec number, I found this on cpu-world:

Mine has QC0R written on the CPU.

QC0R is engineering sample. So working isn't guaranteed. What CPUID it has?

[DeathBringer]

Try to reset CMOS and to boot your QC0R without laptop's battery.

Thanks! I will try that later.

How can I get the CPUID if I can't boot with that CPU?

[DeathBringer]

Try to contact the seller. He should send a proof of working. For example, screenshot of CPU-Z.

Ok, I asked the seller for the screenshot. In the meantime, I found this on CPU-World:

It's screenshot of QC27, not QC0R.

I know, it's the closest thing I could find
