did you reset to default when you downgraded your bios?

so, you got almost the same as me, 10% an hour, even more, nice. but remember, the last 10% doesn't exist actually

how much Wh do you get in the battery monitor? 84 too?

with the big battery, you need to cut some plastic along the baterry, is possible.

is funny, the battery has sort of hole to grab a rubber, so the lcd trim will not press to much against the battery. but, they don't put it afterall, because the rubber will only cut more degrees in the hinge :lol:

Any problems getting yours out?
When i boot mine, it doesnt allow me to get to the setup because of the F1 issue, so i was going to go to the Std battery to load up the defaults in the 00 bios to see if it helped with the battery errors, but I cant get it out
the looking at the underside, the right hand side is stuck (the one with the click open / close latch, not the left hand side with the spring loaded latch)
Seems like its stuck pretty good and I cant get it out! Never had this problem before.. Wonder if the holes are to deep or something and its catching..
anyone else have this problem?

oh oh, i really hate when anything that suppost to be fine turns bad, f*ck murphy's law :x

turn off completely the mini, take off the ac adapter till the lights shut down, then plug in the adapter again, the mini will boot up without the flashing, then you can go to the bios setup.

the stuck problem, shezz, mine is perfect, don't know what to say

I think that normal rechargeable Lithium rechargeable cells (not the special chemistry 1.5 volt repalcement ones) are normally around 3 to 3.6 Volts, depending on the chemical type. So, if there were 8 cells at about 3.2 volts that would mean that each cell would have to have around 3,000 mAH capacity to get 77 Watt Hours.

but is not 77, is 84Wh :lol:

i think this cells are 2800mAh, and the system just read it as 3800 (3800mAhx2=7600mAhx11.1v=84360mWh), the common dell battery do the same thing, showing 3200 instead 2200 as we proved opening a battery to see the actual cells. (viewtopic.php?f=11&t=2278)

so, this big battery is actually 2800mAhx2=5600mAhx11.1v=62160mWh, more than "64Wh" battery some people sell but just have 2200 cell too and report only 48840mWh, exactly the double as the dell battery, 24420mWh (now 35Wh with A04, reading 3200 cells).

that is the reason why the big battery stands for more than double the regular battery, because they use 2800mAh cell instead 2200. so, this is too the real difference between "77Wh" and "64Wh" listed batteries.

I'm thinking about getting one of these.
davico_rosello, you said there's the blinking light issue. I'm a bit confused. Is that only present when you are charging the battery and connected to the AC adapter and does it go away when I unplug it?
When you turn off the unit, can you hibernate it?
Also, are you running A04 or A00 (or something in between)?

Ive run A00, A03, and A04, all exhibit flashing under charging while on, and starting windows without the AC conencted
You can hibernate and run perfectly, but you need to charge the battery while the unit is Off..
I did Not reset to Default before I used A00 so that might be an option..
The biggest problem I have is every time i boot it (even from hibernation) I get a Strike F1 to conitnue, when the AC is not connected before I start..
its annoying but to get 11 hrs out of it, ill live with it till someone can figure out a work around / fix..
