How much time a G51 (with i7, Q9000 or P8700) can last on battery?
1. With the minimal screen brightness.
2. With the WIFI connection OFF.
3. Using only Word.
(alternative question : is a G51 appropriate to take notes in university classes (2:50 --> 3hours))

don't expect battery life in this machine. You won't be able to use this computer for more than 1 hour 30min.
-
I get max 2 hours with G51-RX05 when just using word. Thats with the 6-cell battery. I think with the 9-cell it woudl give you around 3 hours, maybe a bit less.
-
I don't use it in that mode, but got 1:57 before shutdown (5% left) when testing like you wrote. I'd expect the 9-cell to give 3ish as well under same circumstances. With the "battery saver" mode built-in (wifi on, brightness 60%, general web browsing), the deck indeed gets an hour and a half to hour forty-five as fuyuki said.

G51 and battery life should not be used in the same sentence. Oh wait...

this will shed some life on that subject.
clearly an hour out of your battery is about average -
Thanks! Does anyone know where to get a 9 cell battery (I live in Canada)?
Also : does the P8700 seems a better choice for battery life? -

9-cell = 83 wh
6-cell = 50 wh
i get about 4.15 h of my G50vt-x5 wile word and pp slides -
The battery life on this deck is short for sure, but I've never gotten less than 1.5 hours so its not *1hr bad*. Of course, I've never gamed with just battery either so...

y'r welcome.

that would be 15W if on full load at that clock/voltage
-
indeed... too bad, otherwise that'd be pretty cool.
-
Thanks everyone... but where can I get a 9 cell battery (and ship it to Canada)?
-
the g51j doesn't have a 9cell retail yet, for the g51vx you might have to try ebay (not sure about any retailers that sell it here).
newegg had it deactivated, http://www.newegg.com/Product/Product.aspx?Item=N82E16834998726 -
http://www.amazon.com/ASUS-Notebook...TF8&coliid=I1I63R75UZ3Q2C&colid=1482BANTLP3VL
Seems like I got it finally. It says it's for the M50 series, but on newegg the same battery is said to be designed for M50, G51, etc. -
for 185USD, that would definitely hurt the pocket.

Holy cow... thats outrageous. I'm sure theres a universal brick out there somewhere that costs less. Radio Shack maybe? I know I used to have one from Kensington but its wattage only went up to 80-90 iirc. 19v is pretty high as well so who knows.
-
You could get a universal external battery for slightly less

Is a universal external battery as efficient as the ASUS 9 cell? Looks pretty cool: I didn't know that even existed!
(what's even cooler is that I could split the cost with the hole house since they could use it)

ASUS 9-cell - 7200 mAh
"BIGGEST UNIVERSAL EXTERNAL LAPTOP NOTEBOOK BATTERY USB" $150 - 9900 mAh
According to the seller, the external battery has biger capacity than the 9-cell battery.
Other batteries there are 6600/ 7300 mAh etc.
So overall they are similar to the capacity of the 9cell. -
I get around 2 hours on my G51 vx-A1 ; Q9000 processor ; doing what you said.
I don't think its appropriate for class at university tho...
Think about it,
blue lights ; what if prof dims the lights thats just... uh unecessary attention
not only thats I've done it ; its a pain to lug around especially if you have coursework for multiple other classes in your bag for that day. -
For school just get an extension cord
there are an plugs most places.
But just for web/note taking I would get a cheap netbook, these notebooks are desktop replacement gaming machines. -
I don't think I'll bring asus g51 to class. I brought to my discussion class once and people were looking at me/my laptop. Make me uncomfortable. I now bring my old asus v6j to class and leave g51j at my apartment.
-
I get around 2hrs and some minutes on RX05, I turn brightness down and keyboard backlight off. I
