EDIT: I guess
already talked about this in earlier posts regarding bios flaws...so I'm just here to re-emphasize the matter.
It appears that a severe bios flaw has been uncovered by and a few other users regarding all asus g1s notebooks relating to battery charging and processor speed. Evidence of its discovery can be found here: http://forum.notebookreview.com/showthread.php?t=135161
and here: http://forum.notebookreview.com/showthread.php?t=143667
It seems the processor runs at almost half capacity anytime the ac adapter is plugged in and the battery life is less than 90%(+/-). G1S owners can test this themselves by draining the battery roughly less than 90 % and running a cpu extensive benchmark like super-pi or 3dmark, while plugged in on AC. You will notice that your cpu marks will have been drastically reduced from what it would be on 100% battery. This is because the processor will only run at an estimated 1.2 ghz instead of the rated 2.2. This problem does not occur when the battery is removed...only when it is charging does this flaw surface. Some have theorized that this is due to the inability of the 90w power supply to run both the notebook's power demands as well as charge the battery, thus the cpu power consumption was reduced.
Which ever the case, this is a serious matter, since having the processor speed run at almost half capacity while charging the battery on AC is simply too large a flaw to ignore completely. If anyone has any more information on this, please post so we can all have a better understanding of this problem.
And please, if this concerns you, please forward this information ASUS so they can firmly be aware of it's importance to its customers.

Interesting.
I read this about 5 hours ago and did some tinkering around.
Here is the info for anyone who wants to reference this:
Testing system: 3DMark06 Professional Edition
Power plan : Modified High Performance mode
ASUS G1S Series (my personal notebook)
CPU exclusive tests
All 3DMark settings are default values for comparison concerns.
Times of charging are noticed in red, and all times of discharging are in green.
(Battery level - 15% - discharging/unplugged)
CPU Score: 1944
CPU1 - Red Valley 0.613 fps
CPU2 - Red Valley 0.987 fps
(Battery level - 12% - charging)
CPU Score: 1148
CPU1 - Red Valley 0.376 fps
CPU2 - Red Valley 0.560 fps
(Battery level - 78% - discharging/unplugged)
CPU Score: 1932
CPU1 - Red Valley 0.614 fps
CPU2 - Red Valley 0.973 fps
(Battery level - 75% - charging)
CPU Score: 1661
CPU1 - Red Valley 0.596 fps
CPU2 - Red Valley 0.740 fps
(Battery level - 91% - discharging/unplugged)
CPU Score: 1944
CPU1 - Red Valley 0.612 fps
CPU2 - Red Valley 0.988 fps
(Battery level - 89% - charging)
CPU Score: 1067
CPU1 - Red Valley 0.336 fps
CPU2 - Red Valley 0.542 fps
(Battery level - 95% - charging)
CPU Score: 1697
CPU1 - Red Valley 0.562 fps
CPU2 - Red Valley 0.820 fps
(Battery level - 100% - charged and plugged in)
CPU Score: 1939
CPU1 - Red Valley 0.615 fps
CPU2 - Red Valley 0.978 fps
Summary:
Results show that no matter when the notebook is charging, the CPU score is down by 45%. Yet a few tests showed a crippled performance jump.(reference 75% 95% charging)
When the battery was fully charged and the power was drained directly from the AC, performance was identical to a discharge score.
I really don't understand why this performance cut has to occur without the users consent.
If it must happen then offer an option for the user to select during the charging state.

Finally more people are listening. I simply do not know what more to do. We have to call asus atention but how ?? This problem has to go into some press news or something but what ?? asus does not say anything ! this is bad

No, it's not a problem, or bug. it's a feature... because without it, ASUS would have to replace lots of these little brick every year.
Because the little charger almost melts, while it's charging the battery and powering the G1S. No seriously this little thing is a way undersized for "both" workloads, think about it... the cpu & gfx + fan eats alone 30W - 60W, then there's a HDD, memory, mainboard/chipset + memory + wifi, the display with backlit, bluetooth, webcam, ... and a battery that needs to get charged.
BTW, it's not a real BIOS bug either, atleast "some" operating systems don't have a problem with it...
Oh and ASUS has hopefully better things to do than to fix this non-existing issue.

The charger model that comes from delta electronics is the strongest notebook ac dc adaptor from them, charging at 90W(90 series model) with efficency level IV. Considering the cpu uses at Most 34 watts(from intel tech documents), and the gpu having a powersaving feature as well(from nvidia) power consumption isnt a serious problem.
The answer to all this is Intel. It is an internal feature with the new line of processors through Intel's® Dynamic Power Coordination feature.
quote from Intel
Dynamic Power Coordination (through dual core)
"Helps manage voltage and power consumption. One core can demand high
performance while the other core can independently transition to a low battery life or
power state".
kinda hard to be pointing fingers at this point.

Powersaving features? Yeah, right... The powersaving feature are
enabled in _office mode_, but not when gaming!
http://www.notebookcheck.net/Review-Asus-G1S-Notebook.3889.0.html
(go down to the battery runtime... there you can see it: 74,6 / 78,3W!)
you can say whatever you want... the G1S power brick is undersized!

I'm not going to discuss this anymore. It's just plain math for some and for others, they only believe when they see with their eyes.
the last test i did that i didn't post was very simple. Flashed the g2s bios, battery at 5% and did a burn-in during night. 4 orthos instances, 2 usb devices, full brightness, wifi on, bluetooth on and 3dmark 2006 looping. The cpu worked just fine at 2.2 all the time and the battery charged to 100%. The ac-adapter never overheated, never shutdown, better, it did not get hotter than before.
I do not know what to say you guys more. The ac-adapter is enough. the G1s bios has a simple acpi error somewhere.

Why not? Is it only because you have really no idea about electronics and of the "plain" maths behind it, or what?
But yeah, bake your bricks! ;-)

G1s has a 14.8Volts / 4.8A/h battery
P = U * I = 14,8 *4.8 = 71.04 W Battery.
It has a 19V / 4.74A/h Ac-adapter
19 * 4.74 = 90,06 W Adapter
Since like you said at maximum of maximum , it will drain 78W, that means that the battery will last about an hour and it's true. So the adapter has about 12W left for the battery WHEN you are using 78W. The ac-adapter WILL never give you more than 4.74A/h so the laptop WILL never consume more than 4.74A/h or it would have a really bad design flaw, and i do not think that asus would make such a mistake. And they didn't.
Another thing, i did a litle research and have not found a single 15,4 , T7500 cpu with a 8600M-GT laptop,..basicaly about the same specs as the G1s with a ac-adapter with more than 90W. For e.g. the aspire 5920 model with a T7500 cpu. And guess what, the cpu does its thing just fine.
Unless Asus wants to have the only 15,4 laptop on the world that underpowers its cpu while charging they will release a bios fix just has expected.
But, before you think that i'm calling you stupid.. i'm not, because for shure you too have ALOT of time/years with computers , you would have to agree that if i brought the 120W ac-adapter they still had to fix the bios and that's what i'm asking for.I really do not mind and for shure other users, of buying the 120W ac adapter.

Hahaha, man there's a difference between simple math, plain physics and the reality.
(We are not in a classroom with perfect conditions and with a physicist that hopefully knows what he is doing... Instead, "we all" are bound to laws).
- Nothing is unbreakable, everyone and everything has a lifetime...
- Thermal resistance in electronics. A truly vicious circle!
=> The more you need the less you get!
- The famous "reaction rates for many reactions double or triple for every 10 degrees Celsius increase in temperature".
(No, it is not only important for chemical/biology lessons, because it also the main reason why components ages and become unreliable)
- ASUS needs money for living, however there is competition too!
But somehow they all make/sell the same ****! (BTW, ACER's site says that the laptop has not a T7500 and a 4965wifi, but that's really nitpicking ;) ...)
- the laptop _will not_ stop at 90,06W, It will however "leech" as much it needs and the PSU can deliver.
...
And if you still think that "we" are all wrong and that these "basic laws of nature" don't apply for you or for ASUS, please go to your doctor. You need a "reality check" then. ;-)
