SuperOneClick will not work with the latest update (2643).
Use A1 Rooter.

I don't mean to be rude but this exact revolation has happened on this exact thread about 10 times...and been answered thoroughly many times. Please search the thread,preferably before posting.
Secondly, to be more elaborate...pick "flash zip from internal sd card" (or something close, doing this by memory) from the cwm recovery menu, then browse to your downloaded zip file to flash it.

Boot into CWM by holding down the volume down and power button (release power when unit vibrates, release volume when logo appears) one of the choices listed (I think it is the bottom one but don't quote me on that) says install from internal Sdcard. Assuming you have a newer version of CWM. navigate the folder structure till you find the file you downlaoded it will ask you to confirm say yes.
Rooting is pretty painless but I always recomend making a backup first just in case.
Got it done.
Yes. I realize this was very easy. TippyTurtle i got ur reply while i was posting this answer.
so, got it done.
This is how i did it.
For all those ideapad A1 owners who have installed the system update and can't get the tablet rooted from SuperOneClick.
You need to use A1-rooter.
1."www[dot]a1.cu2.at/A1_rooter[dot]zip" ----Download this zip file.
[replace 'dot' with '.']
2.put this zip file in your internal storage sdcard such that the full path is /sdacard/A1_rooter
3."www[dot]doc.ic.ac.uk/~grm08/ideapad/cwm-5.0.2.7-rev3-ideapad-a1[dot]zip" ----------- cwm-5.0.2.7-rev3-ideapad-a1.zip
Download the file "cwm-5.0.2.7-rev3-ideapad-a1.zip" from the above link
4. Copy this file to the root of the internal SD card and rename it to update.zip (so the full path should be /sdcard/update.zip)
5. Power down the Ideapad.
6. Hold down volume down and turn the power back on, keeping volume down held until the tablet boots up to an image of an arrow out of a box with an android (this is the stock recovery).
7. Wait whilst Clockworkmod recovery installs. The progress bar should fill up.
6. Afterwards you should see a blue menu of clockmoderecovery.
7. goto install zip
8. install zip from internal storage
9. select A1-rooter.zip
10. installing should be done in seconds.
11. go back and reboot to android.
12. enjoy..your ideapad a1 has been successfully been rooted.

For other phones/tables, it's probably best to use http://goo-inside.me/superuser/Superuser-3.0.7-efghi-signed.zip - for some reason this doesn't work on the A1 - it fails with error code 0, but I never looked into why this is.
Must phones and devices have custom built insecure kernels (root) built for them. Only exploits like super one click work over different devices. and you risk bricking your device by playing with anything you are not sure how it works.
Lucky there are very few devices that some one has not rooted one way or another.
Not spell checked nor checked for grammar on my genetic phone

It could be that it works for some other devices too, but i wrote it for A1 only and I never tested it on other devices.
Sorry, but what is the latest stock build and kernel version.
Thanks
Update:
now running 015_2643_us build w/2.6.35.7 kernel.
cwm-5.0.2.7-rev3-ideapad-a1 - awesome Lepad_A1_root.zip to get root (post#19)
That is all

It will not work. I tried several versions, to include the most recent paid version. A paid subscription of skype will work, but the video is not quite right. The voice part works fine.

18Just picked up my new Lenovo A1 Tablet yesterday at Fry's! With a little elbow grease this thing rocks! I'm just going to go down a list of what Ive done to make it a sweet tablet.
1) Superoneclick 2.2 will root this baby just need to install adb drivers...easiest root to date.
2) Once it's rooted I installed LCD Density from market and set it to 200. Make sure you select killall and hit reboot.
3) Installed SetCPU from Market. I set it to Performance with the screen on then set it to conservative with the screen off 300mhz/300mhz. Make sure you hit the set to boot button. Once I did this it felt much faster than my Xoom. I havent tested battery life yet.
4) Installed Spare Parts from Market. Set the windows animations speed to fast and transition animations to fast. Makes a world of difference.
5) Installed LauncherPro! Get rid of the stupid Lenovo home screen!
6) I installed WidgetLocker Lockscreen. You can do the Honeycomb screen and re-size it to fit. Gives it a nice feel!
7) Installed the new Adobe Flash11 from market
8) Installed App2Sd and moved all my apps to my 4gig sd card and cleared cache.
9) Picked up a badass 7" case with a stand at OfficeMax! fits perfect! $30 http://www.officemax.com/technology/...^return_skus~Y The website only shows a 10" but they have a 7" version
10) Google Nav works great tethered to my phone via wifi. I'm downloading a offline Nav as we speak.
11) Charges Via USB!
12) Screen gets really bright at max. I just use Auto
13) Skype was working till I did the Lenovo update no video sound works fine. Front camera sucks back camera is good. To be honest I use my Samsung Galaxy2 for all my pictures.
14) As soon as I turned it on and connected to the internet it wanted to update. I don't know what the update is about but it was a huge file.
I'm just getting started with this tablet. I was torn between the Nook2 and Fire. What I love about this is its easy to root comes with Market and charges via usb. I installed Amazon Kindle and Google Books. Their is a new update to Amazon Kindle that makes the app look just like the fire lol.
Anyways hope this helps! Please feel free to ask me any questions. I will be updating this thread as I learn more.
Comes with Gingerbread 2.3.4
Link to ADB Usb drivers. Install first! make sure you have Debug on http://www.mediafire.com/?6v19365dkvc6k8r

If you truly want to go back to factory settings:
1. Install the firmware as described above (this will return your system partition to default and unroot you)
2. Then do a factory reset from Settings -> Privacy -> Factory data reset (this returns your data partition to default)
If you want an easy way to figure out you are having the rebooting issue without having to constantly monitor your tablet, then do the following:
1. Turn on airplane mode
2. Then turn on your wireless (you don't have to be connected, just have it on)
If you come back to your tablet and the wireless has been checked off, that means your unit rebooted on its own. When airplane mode is on, all wireless connections will be unchecked after a reboot. If you don't have a reboot problem, then your wireless should stay checked until you manually reboot.
If I can't fix the tablet today, I'm going to return it.5
We'll get there eventually. At the moment there's progress being made as a result of the kernel sources being available - for example, we're getting the capacitive button light to be always on. All this progress is down to Milaq.
I'm presently working on a safe way to flash kernels, that won't brick your A1 if you flash a bad kernel. I think this is necessary to make it easy for lots of people to test an experiment with different kernels and compile their own, without taking any risks themselves. This could take me a little while to implement though.5Video How-To
I'm removing my presence at the Lenovo Community. I didn't want to lose this, so I'm moving it here:
This is a guide to transcoding video for playback on the A1. In principle, it also applies the K1 but there are no specific instructions for it.
Background:
The processor in the A1 has hardware support for multimedia. It supports a number of codecs (video coding/decoding) and, if the video being played conforms to the supported codecs, playing that video will result in better picture quality and longer battery life.
The "stock" video player only supports hardware playback, so any videos that are not supported by the hardware will not play back properly. There are other video players available for Android that may play videos not supported by the hardware, but because those require more CPU, they may not support as high a quality of video and will run down the battery far more quickly.
A better alternative, when possible, is to transcode (convert from one codec to another) the video so that it can be played by the stock player using hardware codec support. This guide suggests the use of the free transcoding software, Handbrake, which is available on Mac, Windows an Linux: http://handbrake.fr/ In addition to being available on multiple platforms, Handbrake will take full advantage of multicore CPUs to perform the transcoding, resulting in very fast transcoding times -- or, at least as fast as it can be.
Some relevant information about the A1: The screen resolution is 1024*600 which gives it an aspect ratio of 16:9.375. Information about the processor and the codecs it supports can be found here: http://www.arm.com/products/processors/technologies/neon.php
Steps:
Install Handbrake on your computer using the instructions found via the link above
Download the following preset: http://dl.dropbox.com/u/25738269/A1.plist
Using the Options button on the lower-right side of the Handbrake interface, import the preset. It will be called "A1" in the preset list.
Using the source button, find the video you want to convert
Click the preset to make sure it's applied
Have a look at the Scale Dimensions. At this point, for widescreen content, the first dimension should be equal to 1024. For 4:3 ratio content, the second dimension should be 600. If neither is the case, click Picture Settings and change the the storage width or height (depending on wide screen or not, respectively) to 1024 or 600 (for example, 1024*576 or 800*600) -- the goal is to maximize one value to the limit on the A1 without the other going over. This is to avoid the A1 doing any scaling to play the video. Once set, close the picture settings.
If you are going to be on an airplane when you view the video and you do not have a noise cancelling headset, you may want to click on the Audio tab and expand the Advanced section. Bump up the gain a few dB. Careful, though... if you set that too high, your audio will be distorted. Select the destination for the converted video, then press start.
How long the process takes depends on your PC and the video being encoded. For wide screen video the resulting size of the video will be about 0.5GB per hour of recording. For highly dynamic video (action movies, for example) the result will be greater. If you need a smaller video and are willing to give up quality, before starting the conversion, click the Video tab and lower the bitrate value. Values below 1000 kbps will show noticeable degradation, but experiment to find what's right for you. Alternatively, you can increase the bitrate, but at some point, the hardware won't be able to keep up. If you have lots of time, you can also have Handbrake do two-pass encoding for an even better picture.
Sources:
Handbrake will rip directly from DVD.
Flash recordings can be downloaded from sites like YouTube with a Firefox plugin called DownloadHelper.
TiVos are also a good source of video content. You can use the TiVo desktop (www.tivo.com/desktop) or a direct https connection to the tivo (https://[your tivo ip here] using "tivo" as the username and your media access key as the password) to transfer recordings. The recording will be in an encrypted format, but you can use a tool like tivodecode (http://tivodecode.sourceforge.net/) to decrypt it. The result will be an MPEG-2. Some recordings may not be transferable from the TiVo because of content protection applied by your cable provider -- complain to your cable company. Verizon FiOS provides content protection-free service.
