Question about IO Ports on A2109 IdeaPad

2012-11-30, 10:05 AM

Hello Everyone:

 

In a couple of months I'm going to be getting a IdeaPad A2109 Tablet.

 

I couldn't find manuals for it on Lenovo's site so I came here and found the links that I needed Thanks to those forum poster{s}.

 

I ran accross in those links the maintance manual and was excited because I couldn't find anything about any of the connections on the tablet.

And any pictures that Lenovo had on their site while good in general didn't in anyway help really in identifying any of the ports.

I tried to the best of my ability to figure them out, But in any event I digrise...

 

I seen in the manual that it said the Micro usb port was used for Sync to your computer and charging.

OK I figured I can hook my Mini usb Keyboard to that with NP because I already had found out that you could also cahrge the tablet off your computer using one of it's usb ports.

 

And it also said it has a DC JACK?

Which I took as ity having a seperate connection for normal powering from the cahrging of the Micro usb port.

But yet the diagram gives No Indication of a seperate DC Jack?

 

My question is this does the IdeaPad A2109 have a Seperate place to plug in your "NORMAL POWER CORD"???

 

Or is the Micro usb port used for the "NORMAL POWERING" of the Tablet as well???

 

I really hope that the DC Jack is seperate from the Micro usb port so that I can still hook the odd thing to it while still being hooked to AC....

 

If not could anyone tell me how I could use it for both at the sametime?

 

Also let me take the chance to Thank the poster that answered a thread about where the Micro SD Card went, or I would've been pulling my hair out trying to find it...

 

I take it that the Max Size SD Card is 32gb?

 

Sorry for all the questions just trying to know all that I can before I buy my new Tablet.

Some angled adapters will block the HDMI port. This is not a problem for most things but if you plan on keeping your device plugged into power, keyboard etc.... You will not be able to access the mini HDMI.

There is one micro usb that is used for charging and one mini HDMI port. There is no way to use a keyboard And charge at the same time that I am aware of. You can have it charging and have HDMI out running to a tv or something.

There's no "DC jack".  Charging is done via the micro-usb.

 

The A2109 has three jacks, micro-usb, mini-hdmi, and a headphone jack.  You can connect a keyboard to it with a USB OTG adapter.  I use this one, but an OTG adapter should work.

 

The official max sd card size is 32GB, but some have gotten 64GB cards working by reformatting them as FAT32 (64GB and bigger sd cards come pre-formatted as exFAT, which the A2109 does not support).

Thanks for all your help.

 

I already ordered a Micro usb to Usb OTG Adapter that is angled so that's not a problem.

 

To keep from wearimg out the Micro Usb port could I use the the adapter with a full sized male to male usb cable running from the Pwr Adapter?

 

I really don't see how that couldn't work.

 

Second question to be able to use a power andapter and usb keyboard at the same time could you do it through a hub of sort?

But I know that is most likely awful risky to try.

 

Thanks again in advance.

Thanks so much for your post, Blocking the HDMI Port isn't a problem for me because I rarely use it to begin with.

I have a Iconia a500 and I use the full size usb more then anything else.mainly for data transfer from my usb sticks or sync with my laptop. And at times for a keyboard when typing a lengthy Email or document.

 

Having to unplug it from it's power source so I can use these things isn't that big of a deal even though I'd rather have it on power lot's of times.

Like I said my main concern was over taxing the Micro usb port by all the plugging and unplugging to do this.

 

Thanks to everyone for all their advice...

Wasteland, as noted above, it's got the HDMI and the standard Micro USB - which I prefer for charging, as it's compatible with my phone, bluetooth headsets, etc. As far as a keyboard, why not get a mini bluetooth keyboard? I picked up the Microsoft Mobil BT keyboard for $35 at Staples and I've seen it cheaper. (I got the wave style, which makes it work for my large, clunky hands.) It's very responsive with the A2109.

 

For an SD card, I've seen two reviews say that it takes a 64GB micro SD care without a hiccough. I grabbed a 32GB Sandisk from Staples for $29 yesterday, and am happily loading it up with movies and music.

I have had numerous problems get a Bluetooth keyboard working with my iconia and the best part being is the keyboard was made by Acer just for the iconia, So I'm kinda shy about getting another Bluetooth keyboard and not having it work as it should, although I've tossed the idea around about trying the Bluetooth keyboard out on my A2109 just for the hey of it....
It'll hook up just fine, the problem being it skips keystrokes, stutters and the like.
If anyone has an idea on how to fix it I'm all ears....

WSL, I haven't used the new Microsoft KB much - I'll let you know my experiences with it, but so far it looks good. What amazed me about it is that it works with my silly Samsung Infuse phone with Froyo 2.3; I hadn't expected that.

 

A quick correction on my advice about the MicroSD card, in another thread in this forum (look for "MicroSD compatible" in the title), someone more knowledgeable than I posted, "There've been reports here of people getting 64GB cards to work if reformatted to FAT32 (micro sd cards 64GB and above are generally pre-formatted as exFAT, which isn't supported by the A2109).  I would guess 128GB would work if reformatted to FAT32 as well, but I haven't see any reports here of anybody trying it.  Let us know if it works out."

Re: Question about IO Ports on A2109 IdeaPad

Right now I am waiting to get my A2109 in about a month or so, and my wife has got me a 32gb micro SD for Christmas. I now have a 16gb in my Iconia. Which I'm going to use after I get my A2109 for back up and the like.
Funny part of it is the iconia I'm using right now won't recognize anything but Fat32 either.
I wonder if you could do the same with this one and a 64gb?
Your theory about a 128gb or even more if formatted to Fat32 is quite interesting...
