Lenovo Helix GPS functionality

Hey there.
First of all, I have to say the ThinkPad Helix seems to be a pretty awesome piece of kit, however I seem to be having a few issues with the GPS functionality.
I have had a look on the forums however I haven't been able to find any specific information as to the problem that I am having.
The Helix I have is the version with the Ericsson C5621gw 3G network adaptor. From what I understand you have two different types of GPS - standard, and assisted (which uses Wi-Fi/network triangulation to report a semi-accurate location). As far as I am aware, the C5621gw uses standard GPS, however I have been unable to get any GPS to work, even within the Bing Maps app.
When opening Bing Maps as an example, it constantly reports the location as being in London, even when I'm the other side of the country. When the Wi-Fi is connected there is little issue, however when using the 3G the location is always way off to the point of being unusable. I know that the GPS is built in through the network card, and that COM ports aren't used within Windows 8, as it uses a separate geolocation stack to report information based on the Windows Location Provider.
Does anyone have any ideas what could be happening? If the C5621gw only uses assisted GPS based on mobile network location then I guess there is very little that can be done, as this may be a network dependent feature, however if it does use standard GPS then something is clearly wrong. I have location enabled within the OS, and all the drivers are installed as they should be. I have listed the drivers installed below.
On a different note, I also have an issue with the BIOS as well. When tapping to enter the BIOS before Windows starts, it automatically goes straight onto a blue screen and restarts itself. The BIOS has been updated, and I am using the stock OS that came with the device.
Thanks for your help, it's much appreciated

Have disabled Windows location Provider, and went outside and waited for about 10 minutes. GPS did not appear to connect. Maps app does not respond when I try to go to 'my location'. Also installed a Win8 app called 'GPS Satellite' and it showed that the GPS was 'initialising' and would not find a location.
Then installed Visual Studio 2012 and the WDK so that I could run the Sensor Diagnostic Tool. I observe that the C5621 chip is staying in the 'initialising' state and doesn't seem to get out of that.
However, if I re-enable the windows location provider, then I see that:
- Maps now finds a location, albeit the wrong location
- GPS Satellite app now finds a location, same wrong location
- The sensor diagnostic tool still says 'Initialising'. Huh?
So I'm wondering if I'm looking at the right fields in the Diagnostic tool. Either I'm looking at the wrong thing, or the GPS is just not working.
Can you please take a look at the screenshot of Sensor Diag tool and tell me if the red circled field is what I should be looking at?
thanks

My experience is that the reception of the GPS is very poor (say compared to a typical phone GPS or other tablets), and if you are in sub-optimal conditions it will pretty much never get a fix and never get past initialising. e.g. indoors it is essentially useless.
Outdoors with a clear view of the sky it will get a fix, but even then it is slow and temperamental.
I'd be surprised if you could use it as a live navigation device .e.g in a car.

Lenovo Helix compatible Stylus with eraser?

Hoping for some input as to which Wacom Stylus will work on the Helix with reverse eraser functionality. I was looking at the Wacom Feel but it doesn't seem to have any different functionality to the Helix stylus, only different size and feel.
Lenovo Helix i7 256gb... wish I bought a Surface Pro for better support...

The Helix uses the Wacom drivers. That means you can use the stylus/pen that comes with the Helix and lives in a housing in the tablet part, or you can use any Wacom “Penabled” pen. I find the Lenovo-supplied pen to be too skinny for comfort, and the button is flush, making it hard to press. It also does not have a built-in eraser (a minus in my book because I’m a sloppy writer and erase a lot). On the plus side, there are lots of alternatives out there. The stylus I bought for my Latitude 10 works fine (Dell part number 332-0102). I also bought a Wacom “Penabled Tablet PC Eraser Pen (Mfg. Part#: UP710E). It’s identical to the Dell except it’s grey and has no clip. Lenovo does not supply spare nibs. If you write a lot you’ll need a new nib sooner or later. My favourite is the Wacom “Hard Felt” nib (Wacom SKU ACK20003). It’s hard to find, but writes beautifully. One problem I’ve run into is the fact that you can’t use another pen if the Lenovo pen is fully inside its housing. If there’s a setting to turn this off, please let me know! It’s a hassle to have to pull the Lenovo pen out to be able to use mine.

Lenovo Helix - On-Screen Keyboard with Bitlocker

Hi Community,
i've tried to install Bitlocker on my Lenovo Helix with Windows 8.1 Pro. As long as the dock is connected with the tablet, you can decrypt the harddisk with the right key. But if the tablet hasn't a dock or an external keyboard you'll only see the blue bitlocker-homescreen and can't do anything.
Another helix in my company works with bitlocker - so i know it can work.
i've tried the following things:
     - different Bios-Versions
     - install all drivers and additional software
     - set up a new Windows 8/ Windows 8.1 (Pro)
The on-screen keyboard works by adding a Bios-password.
Btw: The helix won't let me install Windows in UEFI-Mode..
Can somebody help me?

current, it runs on legacy boot - the uefi bootloader doesn't work for x86 Win8.1 (http://support.lenovo.com/en_US/detail.page?LegacyDocID=SF13-T0008)
well, i have to install 32-Bit. The helix in Uefi-Mode only boots from the x64-Win8.1-DVD (or USB-Stick)...

Lenovo Helix - Clean Install of Windows 8.1 - Best way to load Software and Drivers

I am considering doing a clean install of the Windows 8.1 operating system on my Lenovo Helix. What I am wondering is if (After I install the operating system) there is an easy way to get all teh lenovo drivers and software loaded without having to download/install each of them one at a time?
If not, is there a specific set or order from which they should be installed?
Is there anything I would lose by doing a clean install of 8.1?
Thanks....

Sarbin,
I only have one device issue that has popped up. My keyboard has begun to work somewhat wonky. Sometimes if I am in tablet mode then switch to keyboard mode the keyboard doesn't respond. It will only respond after several reboots/shutdowns. Is there a good way to make Lenovo System Update reinstall the keyboard drivers? If you have any advice on fixing this issue that would be great.
I also thought I was going to lose all teh Lenovo specific apps when I did a clean install. I didn't. The only one I don't see is one which was called "Lenovo Experience". It was nice but if that is all I lost then I am ok with it.
I love this computer. Now it feels like new again....
You're welcome.
Some things I prefer to install manually, outside of TVSU. BIOS and firmware are good examples. Have a look through the driver listing for the keyboard/dock update and scan the readme. The behavior you're seeing may be part of that fix.
Looking at one of my Win8 OEM-preload machines, the Lenovo Experience shortcut points at "dxpserver.exe". Maybe that info will help pinpoint if there's an installer for the complete package.
Hope this helps.
Regards.

Lenovo Helix - Issue outputting to external monitor

I received my Lenovo Helix today and am having issues outputting to an external monitor. During initial setup output was working but with the occasional flicker, so I performed all Windows Updates and Lenovo updates, however now it will not output to external at all. Monitor is a Dell 2740L 1080p monitor using a Kanex MDPHD10ft mini displayport to HDMI cable. Any help would be greatly appreciated.
Lenovo Helix i7 256gb... wish I bought a Surface Pro for better support...

Has anyone found a solution for this issue yet? I was unable to get the Intel HD Graphics driver 9.17.10.2932 or 9.17.10.3071 to work. Sent the computer in to Lenovo; they have replaced the motherboard three times. I'm surprised that each time they sent the computer back, they didn't check to see if they had actually fixed the output problem.
It appears that the problem lies in the Intel HD Graphics 4000 driver (see: http://www.eightforums.com/graphic-cards/7743-those-troubled-hdmi-sync-issues-intel-hd-3000-4000-etc... ).
For a company with a long legacy of sucess, Lenovo has sure disappointed this time. It's going to be hard to recommend their computers to anyone if they can't even acknowledge that they put a nonfunctioning port on their laptops.

Lenovo Helix - sending to second screen issues

Hi,
so i recently tried hooking up my lenovo helix up to my Sony TV (i don't have any more info on the TV than that, sorry) and a little bit of the screen on my helix was cut off, so i couldnt see the task bar at the bottom, or the tabs at the top of my browser. I was watching youtube, so it was pretty frusterating to watch in full screen mode because i couldn't see the progress bar at the bottom. i looked through the built menus on the TV, and couldnt find any way to change the dimensions. i was wondering if there is someway to change what size the screen is thats being sent on my helix. thanks in advance

hi TheoNet,
Welcome to Lenovo Community!
That cable you're using is meant for HDMI to VGA.
I believe that this will not work. "VGA output only provides analog signals while HDMI input will only take digital signals".
Converting it through a cable will not work. It can be possible but you will need a Signal Trans-coder that converts analog to digital signal like this:

Hope this helps

Question about the GPS function

I have just got my iPhone 3G, but still need to wait a couple of days to
get my mobile number transferred.
My question is: i don't have at the moment any mobile services from my provider.
(No Service) I do have a WLAN connection. Should my GPS function in Google Maps still work? At the moment the icon is only spinning spinning and spinning....

Thanks All!
I turned it off and on again. waited a couple seconds outside (in the rain )
And it is working great. 100% accurate
Thanks Again.

Find location without GPS function

Can the user have their location detected via a WAP site without the use of GPS? In the case of search for nearby locations via a directory service on WAP without GPS functionality (when user cannot download app version).
Thanks!

This cannot be done directly. Phones with GPS will have the 'network positioning' feature which helps to obtain a GPS fix if satellite signals are poor, but I'm pretty sure it can't be used as standalone location method.
Any phone could theoretically know its approximate location based on which network base-station it is connected to (this is how network positioning works in GPS phones), but there is no software that I know of to put this information to use in the way you suggest.

Lenovo Helix - Max Screen res? 4k?

Just picked myself up a 4k TV and wondering if the Helix would be able to handle outputting 4k video from DP to HDMI 2.0? Or is that asking a bit much of the older intel graphics?
Does anyone know?

That may not be correct. I am pretty sure I have the old X1 Carbon Touch (gen 1, 3rd gen i7) driving 3840x2160@30Hz 4K display via miniDisplayPort, it only has HD4000
Any tips on mini DP to HDMI cables? Or is this DP to DP?
I had a Kanex mini DP to HDMI, but it got savage artifacts and screen flickering at 1080p, gave it to my sister for her mac to run at 1080i and had to run a mini dp to dvi for 1080p.

Lenovo Helix i7 CPU cpu clock down after Bios 1.14

Hi all.
I have about 25 Lenovo Helix, and I must admit that I'm a little angry - I have found out that after bios 1.14, then run the only maximum 2.5 GHz, whereas before it ran 3.0GHz - not that I have purchased. It's an easy solution to the heat, just to clock the CPU down.
Is there anyone who can help me, what can I do? Some have bios 1.10 to lie, it works with the real speed. You can easily feel the difference.
Thank you

Use a program like coretemp and after executing the program hit F4 or from the menus select logging. Run some processor intensive applications, either software (AutoCAD, hd video, etc.) or benchmark such as (IBT, Ortho, etc.) then review or post the csv here.
The multiplier is a ratio of the cpu clock rate and front side bus. For instance, with the Helix the fsb is just under/around 100mhz. The clock will either throttle down to 8x and speed up to 32x, resulting in cpu speeds between 800mhz to 3.2Ghz, respectively.

Will the Lenovo Helix Digitizer Pen work with Windows 7

Hello forum,
I work in the IT department and we have recently order a number of Lenovo Helix to use for special projects.
We will be downgrading to Windows 7 64-bit.
My question is will the digitizer pen still be supported by Windows 7?
Maybe I over looked, but I did not see any drivers that seemed to be associated with the digitizer pen or any previous mention of this and downgrading to Windows 7.
Any information you can provide will be helpful.
Solved!

Welcome to the forum!
Stylus pen is natively supported by W7 and it will work "out of the box".

Iphone 3G GPS function

Hi,
Has anyone recently been having trouble with their Map App? The GPS function do not track me accurately... I could be 2 blocks away or 20 blocks away. It also does not smoothly track my position either, all over the map. Plus the range for the potential position is large as well. My area has great cell phone coverage, so GPS shouldn't be a problem.
Anyone else with this issue? Is there a fix to this?

I am having a similar issue with my 3GS.
The map app runs very slow, when loading my current location, trying to find a new address or getting directions between address. This happens on wifi or 3G network.
Also the map app has 'lost' it's accuracy to the location. Usually it is with in a 2 or 3 block radius, but on the old operating system it was much more accurate and quick.
I upgraded to iSO4 and had issues at first with the lost connection, and i got the error message to re-calibrate in a figure 8 motion. I re-synced last night to solve the 'fuzzy pictures' issue and now the map app is just slow.
Any one have a solution. Should I back up and restore. Advice???
