[Request] Dell Inspiron 17r SE 7720 Unlocked Bios

[Oleh]

I appreciate your persistence, but this is unreasonable obstinacy ... cooling system can not cope without overclocking the video card ... I will not make waves with overclocked video card

[M.I.R.]

Thank you for your quick reply. I am aware that there is some risk in extreme overclocking and I have no effort to do it, but the card's frequencies are stock at the 735 MHz instead of 850 MHz. GPU Boost is disabled even though in older versions it ran fine. From my point of view Dell sold me laptop with worse graphic card then it was advertised.
Anyway, my question was towards your BIOS mod and wheter it's (at least relatively) save to flash.

Hello, I see there no successful to flash on my laptop. My laptop been bricked now. As, you can see no one reply because they cannot use that laptop again. Any way to get my laptop back and research on bios mod?

Once, I flash on my laptop. However it did successful to access all bios. I hit power button to turn off and turn on. It only show keyboard LED and power button LED, however I don't see fan is spin. I left laptop for 10 min, however chipset is working fine but keyboard or fan ain't response.


EDIT: It does not running LCD Display or Hard Drive. My old hard drive been insert to my laptop. It should make noise by now but it don't.

I got bricked too. After flashing i accessed bios settings, changed nothing just looked around. The used laptop for a half day. After restart - just black screen.Still looking for solution how to flash in Phoenix crisis mode. I don't blame you, Oleh

I did take off CMOS and put back. Still no luck. I think Bios corrupted by after shutdown or restart. However, I did notice that my laptop NEVER recognize my usb flash when hit END and plug power same time. I think it required to tjag or other way.

I've got COM from asus motherboard that can control my bios but I don't have tjag equipment :\

Signed up to answer this one... This may be a result of a known bug on the 7720. The temporary fix is to shut down, disconnect power, remove battery for a few seconds, replace battery, replace power cord and reboot.

The bug occurs when you pull the plug whilst it is on and it drops back to battery power, this disables the boost as expected but for some reason it doesn't renable it after putting the cable back in even after a restart. Pulling the battery completely appears to reset some internal memory that is causing the bug.

Dell are looking for an affected laptop in the USA area in order to troubleshoot this issue as they are unable to replicated the issue on their test machines. Please voice your view in that thread if you are USA based.

Hope this helps.
