Multiplier locks to 6x when plugging AC

Hello,

After some progress with my problem I decided to start a separate thread as this doesn't quite fit in anywhere.

The problem is that my laptop (g1sn) runs full speed on battery ONLY. The moment I plug in AC adapter, the cpu multiplier locks to 6x instantly in the middle of 100% load. I've read this could be due to the system not recognizing ac adapter and not allowing the computer to run on full speed, but the only incidents I've found have concerned dell machines. And this happened quite randomly, as I've been on ac for a long time.

I've tried the reset button on the bottom, didn't help. When on AC power rmclock, crystalcpuid and others are helpless changing the multiplier, it won't move.
Also, noticed that Rmclock behaves oddly on full load. If I enable all the multipliers and adjust voltages, no matter what I put on the max multiplier it jumps to full voltage on load. If I select only the max multiplier and deselect others, then it uses that voltage.

 

Ok, formatted and reinstalled windows.. problem is still there. So I guess something happened to the bios or some such.

Does someone know how to really reset the CMOS or BIOS on G1Sn ? I've tried the reset button but im not sure what the heck it does. I've tried it unplugged of ac and battery, on battery, on ac, for 30 seconds, clicked it 10 times, it doesn't seem to do anything. Doesn't even reset the time and date so Im guessing its not resetting anything else either.

Probably reflashing bios would help too, but theres only 1 bios out there for the g1sn, the 202. Winflash won't allow me to flash the same bios, because its "older" even with same date. Any workarounds (like modifying the bios date to 1 day later) or so ?

 

Jesus.. I've formatted windows, formatted and reflashed bios, what can I do ?
edit: Eh, well.. now it stays on 6x even with battery

 

Im not sure but there could be a problem with the ac power. As far as I know, it should stop charging and the charging led should shut down when the battery is full, right ? Well, it says 100% (plugged in, charging) and the light wont go off

edit: well, it just turned to fully charged, just took a long time. I just noticed that playing with the maximum processor state % I can get it to jump from 1200mhz and 1,0V to 1600mhz and 0,9V which is a bit strange to say the least. I have no idea why at 58% max processor state it goes to 1,6ghz and above that it downclocks to 1,2ghz.

 

Please, does anyone know anything about the method the laptop determines the multiplier of the cpu ?

 

What are your windows power settings set to?

Set it to Always On and see what happens.

Also, what are the CPU temps when it's jumping around? If the CPU gets too hot it will downclock itself.

 

Temps are very normal, around 55C. I've tried with windows power management to the point of frustration, no help can be found there. Also tried p4gear, but nothing.

If I set max processor state at 58%(in windows power plans) it switches multiplier to 8x and voltage to 0,9.
If above 58% it goes down to 6x and voltage goes to 1,0V

I guess it somehow thinks at 6x IS the high performance state and when the max. processor state is lowered it switches to 8x ? I see no sense in all of this.

e: just played again with rmclock, everything works very smoothly with only battery.

As soon as I get the "AC MODE" icon on screen, everything is messed up. Multiplier and voltages are completely unregarded by rmclock and so on.
It switches to 6x multiplier and 1,0V voltage on "AC MODE", no matter what.

What program displays that "ac mode" icon on screen ? Or what else is going on when I plug the ac in ?

 

I have the same problem and now it has been sorted!
