I'm going on a longer trip so naturally I will be bringing my Galaxy S3 so that I can watch some movies. Naturally playing them from a USB flash drive will consume more power than just playing them from the internal memory. Obviously I am wondering how much faster this will drain my battery. Would be nice if someone could chime in.
If you planning to play or watch movie, you can except to have 4-6 hours of use of a movie i guess.
I would put in internal memory if i was you.
[Q]s go in the Q&A. Doesn't take a genius.
My advice would be just get a spare battery or two, but additionally, carry the film's on the stick, then when you want to watch one just copy it into the phone and watch it from there then you don't need otg connected all the time....simples

hi
fresh implanted a goflex slim 320go in dock
but its a little bit too high the keyboard curves a little and the transformer don't close exact (the hdd is 7mm)
removed battery
maybe is better with a 1,8 inches hdd
don't know if half battery works i will make tests an post in a few days
hdd is not showing on win 7 , how to see it like microsd (folder)? or howto access it through the ccomputer?
(WORKING ON HC3.2!!!!)
thanks for relplies
Niceeeeeeeeee!!!!!!!!!!!

That's cool.
You can't access the drive because it's mounted on the OS while the "SD Card" internal storage is treated as an MDP by your PC not a Mass Storage Device.
Looks like you should try a Seagate Momentus Thin drive (7mm height). The 320GB one is USD$80.

Can you post a few pics with everything put back together, I wanna see how much the HD makes the keyboard bow up.
Wow, Love the Idea
you know what makes it better use SSD 120gb drive with now risk and less space needed
Wonderful, OP! Imagine the possibilities if we could boot from HDD in the near future... it shouldn't be too hard assuming we can now boot from microSD, right?
hi thank for advices an replies
i have no idea about android boot etc.....
waiting for windows 8!!!!
finally i removed entire battery i dont know if its working or not! and recenter the hard drive
it fits better and less keyboard deformation
452 grams (battery removed and front weight metal piece) total 1240g
added usb hub 4 port (microhub) for future implementations

It appears that windows won't see anything connected to the keyboard. I had the same trouble because windows won't see an SD card in the keyboard. I have a thread on it with some work arounds. I don't know if the problem is Asus or Android. Hopefully they will fix it. I will talk to the Asus service repair center about it next time I go. If you find a solution, please let me know.

Check here for ways to move data from your computer to the harddrive in your transformer's dock.
Also, do you mind elaborating on how exactly you hooked up your hardrive?
It looks like you added some wires to one of the existing USB ports, but I can't tell exactly what is going on.
hi thanks for the link
hooked with strong adhesive tape
wired the usb microhub to board contacts cutted pins of the usb connector and rewired to it
Thanks for the pictures.
Maybe it's also possible to add a 3g Stick permanently into the dock!
If i understood you right you "added" a USB-Port to an existing. Is it now possible to plug in 3 USB devices? (Your ssd, and 2 other)?
@markolino72
Did you get a clue which pins of the connector are used for usb host?
thanks

It *is* a Momentus Thin. The GoFlex Slim 320GB is based around that drive, it just ships in a 9mm external housing (but it looks like the OP has removed that.) A better fit would need a drive less than 7mm thick...

I'm curious what a rotating drive does to the dock/tablet's battery life...
4 cables for usb red gren white black
red and black for power
green and white for data
there are two more ports aviable on the added microhub
maybe a usb drive is a better option and keep battery inside dock
(f***ing missed usb port on tablet....grrrrr) this will be a nice mod adding a usb port and 3g dongle on tablet!!!!

Cool! but be careful with harddrive. Don't use it in the shaky environments.
That's how I killed my laptop's harddrive once. Also, half of the battery(one cell I assume) might not work if they were connected in serial, but if they were in parallel then it should just decrease capacity.
If you detach all of the cells there is a chance that you will erase controller's memory. So, you won't be able to use dock's battery at all. Battery makers are clever these days, they don't want people replacing old cells with new ones.

Yeah, I didn't catch that when I glanced at the pics, thought from the way the dock bowed upwards that he'd put it on top of the battery. A rotating drive that's (presumably) powered on all the time, plus the keyboard and touchpad, USB and card readers, etc. all piggybacked on only the tablet's battery must put a serious hurting on battery life. I'd be amazed if it gets past 3-4 hours -- at which point, why not just buy a netbook? Plenty of them will manage that long or more, with a warranty, an unbowed keyboard, and a heck of a lot more versatility.
I can't see this as being useful beyond the geek "Well, I did it and it worked" value.
well,
I was thinking this for travelling, when i realised that the dock is too heavy to take it arround for only autonomie ,9.5h is pretty enough for me, i haven't make test already but i intent too use the dock plugged if possible
in 320go i can store my music collection,flacs apes i'm a meloman ancd copy the wanted music to the tablet etc...etc when needed and TF souns good!!!!
i thing you are right Aligatro seems my battery d'ont worked anymore tried to resold half and nothing tried to brige "serial" and nothing so maybe DON'T DISCONNECT THE BATTERY
finally I curved the dock by hand gently and its almost flat and closes well
I feel that the keyboard sucks, too heavy ,the best functionality of the dock is too stand the tablet , the mouse sucks too with stupid colors for a mouse pointer
i had to buy a dock for connecting a usb drive......!!!!!
but result is too heavy
the hdd stops frequently with the screen so is not always on only on demand so its nice for copy content to sdcard for use.......anyway you always can unmount it too preseve battery power
i will make a test tomorrow for battery
hi begin battery test
playing music from hdd with wifi and gps off autobacklight
~2h30 for 33% battery ussage so we can expect 7h30 not bad

Well neither do I, except for the 3g-dongel built in.

Anyway you can stick a 63 inches flat panel also together with a 5.1 all of that with shinny duct tape ?
I am travelling for 6 weeks very soon and my TF300t is my source of interaction with the world..
Only issue i have is, it doesn't charge via usb unless its plugged in via wall..
The planes support USB but it's not much use if i can't charge my tablet whilst watching a movie..
Anyone got any suggestions to get around this problem?
Pretty sure in order to charge via regular USB you have to have the tablet powered down. And it would be a slow charge.

And it is slow, but it does charge.
The user manual states that the tablet does not charge via USB while turned on.
The truth is that it does charge with the screen on, but like others say, it's excruciatingly slow. Think 10% every two hours at best.

The real issue is that recent tablets consume more energy than what the USB ports can provide. Check this wikipedia page, and consider this:
The following "benchmark" (vaguely speaking) were done while driving, using the same power source (cigarette plug to USB converter, outputs 1.0 A):
- I had an HTC Hero (Single core, ~520 MHz) which could be charged with any work load on the phone (gps on with Maps/Navigation, while talking and using data while using the CPU at 100%). At worst it was simply charging slowly. Usually I had no issues with charging speed
- When I switched to a Galaxy S2 (Dual-core 1.2-1.4 GHz), I noticed I couldnt use Navigation (implying GPS here) and playback streamed MP3s over 3G anymore and expect the phone to be charged in the process. Over a ~1:15h drive, a fully charged phone lost ~15% if not more of battery charge.
My first big GS2 trip was one where I did the whole thing over Naviation with GPS in car, with local MP3 being played back. I had to pick up somebody when I had done 3 hours of driving, and I noticed that somehow I had around 50% battery left, and I made sure it was fully charged before leaving. Later the same day, I had more Navigation and GPS usage coming up (an additional 7 hours trip). So I used only Navigation/GPS, to attempt charging, and I could get it back from 30% to 70-80%.
Mind you, that was over a STOCK Samsung Android installation, maybe that wasnt optimized for battery consumption!
Even though I dont have any spec numbers and such, it's only normal that your quad-core tegra 3 can't be charged over USB. That being said, with the screen off and the tablet idle, you can still charge the tablet (like others mentioned), since apparently there is an additional, slower but less power hungry core being actively used while the tablet doesn't have alot of things to process. Read this wikipedia article.
EDIT: I am also often in either fastboot or recovery mode on my TF300 these days, and after a few hours "idle" in either recovery or fastboot, I noticed the battery indicator was in the 75-80% range the next time I booted Android... and thats with the device plugged in the whole time! My guess is that recovery/fastboot doesn't use (or recognize) that additional low power core. Either way, sorry for my ramblings, and mods, sorry for my over 9000 edits

I think this is explained in the manual that came with the tablet. Might want to refer there!
Hope someone here can help me with this? I use my Nexus 10 mostly for watching movies and reading ebooks, which are stored on a MicroSDHC. This I can connect to my Nexus with an USB OTG solution and it works flawlessly. The only problem being, I can not charge my Nexus at the same time and watching movies drains power reasonably fast.
Are there solutions so I can use OSB OTG and at the same time charge my Nexus 10?

No, its a hardware/firmware level issue.
I just briefly tested this with my POGO charger and it appeared to continue charging while I accessed files on my sdcard attached via USB OTG. I attached the POGO charger and let it start charging. I then mounted the flash drive via StickMount. Based on the animation of the battery icon in the status bar, the device continued to charge. I browsed the drive w/ ES File Explorer, opened some photos & pdfs, played a video and the battery icon continued to show it was still charging. Whether it actually was charging I can't say w/o more in depth testing. It could be that when the tablet is playing a video or game or something it's using more power than it's taking in. The battery level may not go up but it may not drop as quickly.
This is just based on observations with the quick five minutes of testing I did. I don't know enough about the hardware/firmware limitations. And it would require more thorough testing for me to say definitively whether or not the device will charge via POGO charger w/ USB OTG device attached; testing I'm not too inclined to do right now. I'm sure somebody has already done that & hopefully will chime in.

Interesting. So just plugging in a USB OTG device will disable the POGO charge port? Good to know.

When I am at home using my laptop, I normally plug in the charging cable and take out the batteries. Now for some obscure reasons, I want to be able to do the same thing with NST (or any other eInk eReaders). Is it possible? If not, why not? Can we do something to make it a possibility?
This can be useful for instance for when I am at home... Whenever I know I want to use the NST in USB host mode (as an eWriter, Android tablet, gaming, playing music, GPS whatever), I'd like to take out battery and use it while directly plugged into wall charger or laptop usb port. Possible?
Why take out the batteries? They are doing no harm.
If you want to hang the Nook permanently on the wall, Ok.
If you patched u-boot.bin, you could get the Nook to boot without a battery.
You could also do hardware mods to the Nook to make it work that way.

It was exactly that post of yours (and the other one you referred me to) which gave me this idea. It might be just emotional but I want to preserve my batteries as much as I can, when I am on wall charger, so I'll take batteries out. It's been mentioned that for Li-ion batteries you can safely leave batteries in while charging, but... oh well, me being me I guess!
I'm interested to know both how to do u-boot patching AND hardware modding for this purpose. I guess I have so much to read.
You're the man, oops, ehem... woman, dear Renate.

I assume you want to preserve your batteries. You will only affect this type of batteries life/effectiveness by constant charging at 100%. Even then it will take a long while to notice. Many newer laptops (last 3-4 years) will give you bios option to charge up to only 80%. This is the sweet spot for charging life.
That said leaving your battery in your laptop/nook gives you some serious benefits. The amount of power surges, brown outs and rf noise on power lines can seriously screw with your system. That click of turning a light switch on goes through to your computer. Ok motherboard will have some filtering etc but I'd still rather have a battery protecting me. As to brown outs and surges these can cause corruption. I get a lot of power cuts and I wish there was a minimum power off length. e.g. If power is disrupted it must be off for at least 2 seconds. This lets devices power off and then switch on. The problem is where power dips for 0.5 second. This is enough time to affect your system. Possibly affect contents of your active memory and harddrive cache. Your system keeps on running and slowly overtime gets shredded.
Bottom line how much does a battery cost? Any battery for laptop is going to be <£50. How much does your laptop cost?
As to a device bursting into flames if you use a third party battery or charger its a possibility otherwise very unlikely.

Thanks once again for your comprehensive well-thought-about response.
About the bottom line, you're absolutely right. I read somewhere that the most killing factor for laptop is heat and one part that heats up most is batteries. One of the reasons I took it apart was this. I have to admit that I'm not electrically knowledgeable enough to claim anything. Just trying to be as green and liberally conservative as possible.
By the way, worth a watch: http://www.youtube.com/watch?v=MD6AiWP2VsY
Hi,
I have lots of movies in my 1 TB external HDD, and I usually watch 2 movies a day.
My question is if it harms the HDD if I unplug it when I'm done with it and then plug it again hours later? Is it better if I just leave it plugged? Won't it shorten the HDD's life?
Depending on the HDD. Most external are made to be plugged in and unplugged. It will be the connection that could break. I had a three year old 4tb Seagate attached Andi died in about 3 months.
I made the switch to a 8tb WD Mycloud ex2 and couldn't be happier. I also run Plex media server of of it to save space on the 16gb shield.
I would recommend at least swapping out the HDD for Nas hdd. They are made to run constantly and hotter without damage. Dont be like me and loose movies and music. Do it before it's to late. And backup, backup, backup!
