Aspire 7720G major upgrade

[milolosiu]

Warning!
To anyone, who`s unblocked bios by "insydeFlash", if you patch your bios, and from any reason you wanna come back for orginal bios, your computer can halt when patching, and you must make hard reset, and when you switch on your laptop you will see... nothing. Black window. I unplugged power (AC) and baterry for about one minute, and then bios was back .
Sorry for my english, i`m beginner :P



BTW, great forum and greatest topic! On polish web sites all upgrades, unlocking bios, oc etc. is IMMPOSIBLE! Anyone says "immposible to do this; it you broke your laptop" bla bla bla... Here all is possible ;p

@diegus: Try the "Black Edition" BIOS (available in the x920G / MXM BIOS discussion thread). That event log entry likely indicates a DSDT bug.

If you are brave enough, then set InsydeFlash to also flash the PEI region (the EFI equivalent of a boot block), to get the full update. (The only new feature that requires this, though, is the CPU spread spectrum fix - I changed the spread spectrum rule to Center Spread, to fix the slight CPU downclock I experienced with a T9300, which would show up as 2493MHz, instead of 2500MHz. Just a cosmetic issue, really.)

@milolosiu: Note that this may not always work. Usually an Fn+Esc reflash is required.

Hello you guys!
I successfully replaced the old 1440x900 LCD with a brand new 1920x1200 (WUXGA) LCD. It's a cosmetic update but a must-have, everything looks so sharp now.
Also, installed a Bluetooth 2.1 module which I didn't get with this notebook, it was just bugging me to have a Bluetooth button with no function

Thanks for info with Fn+Esc

This notebook is monstrum for upgrades ;d


@ttomorad
How graphic card take this LCD? Good quality? Hotest temperatures? Decrease fps in games?

[ttomorad]

Picture quality is great! Viewing angles are pretty much the same as on the old one but resolution is awesome, a big upgrade for sure. I don't play much games on this notebook but GPU temps haven't changed at all when doing stuff in windows.

Also, I forgot to mention that I bought a new battery, 5200mAh - 11.1V. Can someone tell me how long your notebook lasts on battery only?

[milolosiu]

My notebook on baterry lasts ~30min with web surfing, but i have non orginall baterry.

I have one more question, On gf 9600m gt radiator is the same which on 8400m gs?

[ttomorad]

It's the same but you need to make a minor adjustment to the heatsink pad because it doesn't lay down properly on the GPU core. Do this if you want to be sure you have a 100% contact, but I can confirm that this doesn't need to be done, I didn't mod mine and I have decent temps, but I don't play games so I don't know what would be the max temp doing that. In Windows I have max 55C, but most of the time it's around 40-45C.

[milolosiu]

Lol, on mine 8400 temp in windows are 60°+, gaming ~80°+

Did you tested Intel Core 2 Extreme X9000 after bios unlock?

[ttomorad]

No, I don't have it anymore

[milolosiu]

No good :/ Will you try overclock gpu/cpu ?
