Lenovo V 560 major Wifi & Graphics problems!

Hello, i am new here. Last week i bought a Lenovo V 560 Laptop. I have been having problems since then..
The first and biggest problem is the WiFi, i cant get it to work, tried everything and a bunch of drivers. I am no expert but no newbie either. I consider myself a smart dude but i cant beat this!
The system cant find any wifi network and in the system manager i have a yellow dot on the "Network controller" and cant find a driver who works there.
I am running Windows 7 now.
Second problem is that the computer say i have two graphic cards, the Intel HD Graphic and the Invidia M300 graphic card, but the system and the monitor only recognise the VGA Standard screen, and its not possible to switch in Bios...
Anyone good on this stuff here ?
Thanks in advance

hey Roberto36,
i recommend going to this link : http://consumersupport.lenovo.com/us/en/DriversDownloads/drivers_list.aspx?CategoryID=607595
and update all your drivers accordingly.

White Macbook with MAJOR wifi reception problems

I live in a small flat and used to be able to access Wifi everywhere on my white Macbook (early 2006) model. This is no longer the case and I can only pick up wifi signal in my living room (i.e. within 7 feet of the router).
It is not a router issue as my iPad, iPhone and even my girlfriend's first generation Ipod Toch can access wifi anywhere in the flat. Very annoying! This computer is used by my girlfriend for university and there are only several areas of her college library where she can access wifi.
I took the computer to the Apple Store in Covent Garden and it immeditely showed full bars of wifi coverage throughout the store. The Genius Bar guy ran some tests and said the antenna was fine. He showed me how to delete and reinstate the network, which I did to no effect. I've also moved wifi to the top of the list in Network settings. Still only works within 7 feet of the router.
Can ANYBODY figue out why my Macbook has suddeny become so bad at picking up wifi?
The Macbook is running Lion, but the problem started when still running Snow Leopard 9and possibly Leoard too).
Any help would be very gratefully received.

You need to go into your router to change the channel it is using. If you check your router manual you will find how to get into its setting. I get into mine by typing 192.168.2.1 into my browser bar. some use routersetup again typed into browser. If you havent got your manaul just go to the company who made it and you can view it there.
Otherwise let me have your router make and model and I will find out how you do it and post here.
Could you see what channels your neighbouring networks were using ?
Also just out of interest I live in the UK and lately my wirelss keeps defaulting to BTopenzone which is clearly on a network nearby, so make sure your system is connecting or trying to connect to your wireless network, not anyone elses.

X230T - Major Windows 8 Graphics Problems

Hi all,
I own a X230 Tablet with the Intel HD4000 running Windows 8 Release Preview. I know it's still a beta but I was just wondering if anyone else has run into major graphics problems on Windows 8 Release Preview. I'm currently using the most up to date W8 64 bit Drivers from intel.
There is a huge amount of clipping, flickering and white backgrounds being shown as black. The apps I've noticed this in are OneNote MX (whenever pen input done), Windows Reader (All PDF white backgrounds are shown as black) and Internet Explorer 10 Metro (Tab previews have black bacgrounds). This is strange to me, though I've found at least one other X230T owner with identical problems.
Pictures, videos and descriptions can be found here: http://answers.microsoft.com/en-us/windows/forum/windows_8-winapps/intel-hd4000-onenote-mx-w8-reader...
Just wondering if Lenovo engineers are aware of this issue and if a fix exists/ is being worked upon. It's somehwat fustrating as it makes many core Windows 8 experiences unsuable (which was the point of buying a touch screen laptop).
Thanks
Solved!

welcome to the community.
how do the intel beta drivers you're running compare to the beta lenovo drivers available in the matrix here:

New iMac freezing, showing Graphics problems and Wifi Problems on 1st Day

My sister just received her new iMac - 20 inch - 500 GB drive.
I started seeing problems during the download of the FIRST software update from apple. There was a black box in the lower left corner of the software update window where it should have been grey (or metal).
On reboot, I also occasionally show weird flickering graphics in the lower right of the login screen.
My new iMac also frooze about 4 different times during the installtion of various updates during the first 4 hours of use. Mouse and keyboard would not work. Once it frooze at the login screen after clicking on the user name.
I also had wifi issues. After three hours of use, my STRONG wifi connection was lost. Moreover, I could not see any other wifi stations. (normally I would see 5 other wifi access points from my sister's neighbours). After reboot, the other wifi access points would appear including my sisters but I could NOT connect to my sister's wifi access point. It said I had an error. I checked the keychain and it showed the right key/password for my sister's wifi AP. I had to run Mac Network Diagnostics and reset wifi to get things working again.
It sounds like a sick iMac. I know others have experienced freezing. But given all these problems, should I ask for a new imac?
Rob
P.S. My sister got AppleCare as well. Maybe that was a good thing...

I had a long chat with Apple Support. It would appear that Apple's policy is not replace the computer unless it can be determined that it is a hardware problem (even though my problems started to appear right out of the box before I even had a chance to download any updates). According to the Apple product specialist, sometimes there are bad installs of the OS at the factory.
Apple wanted me to format the drive and reinstall the OS.
Fortunately, I did not have to reinstall the OS! I started to see graphics problems when I was asked to run the Disk Utilility off the Install DVD (so I could format the drive). So clearly there was a hardware problem.
In retrospect, I really wish there was an Apple Store nearby to buy Apple computers. I am sure the store manager would not ask me to go home and reinstall the OS etc and try again when the computer doesn't work properly out of the box.
Those who have Apple Stores nearby do not know how lucky they are!

Major graphics problems, 7300 GT

Hello.
I have a white 24" iMac with the Intel Core 2 Duo and the 7300 GT graphics card. Upgraded to Leopard and 3 GB RAM.
About a year ago I started experiencing graphical problems while doing things that involved a lot of GPU activity, like playing a 3D game in Windows. Textures would become discolored and corrupted to the point of not being able to play the game. After letting the computer sit for a while it seemed the issues would be alleviated, but the same symptoms would recur after running the game for a while.
I eventually began to notice similar issues occur during much less demanding usage in OS X. Graphical glitches would appear on the desktop and in active windows. When the glitches got especially severe the display would freeze and the system would have to be rebooted to be usable again.
This seemed like a heat related issue, to me. I took the computer apart and cleaned the dust out all of the ducts and fans, but it didn't seem to help at all. I installed an application called smcFanControl, which allowed me to force the fans to run at a faster speed. While running faster, the glitches stopped occurring and the system would no longer freeze.
Things were okay this way for several months, but now, even with smcFanControl set to run the fans as fast as they can go, the glitches are beginning to occur again. Entire windows become discolored with a cyan hue, and random artifacts show up in random places on the display.
Here are some shots to demonstrate what is happening:
http://horseface.org/iMac/1.png
http://horseface.org/iMac/2.png
http://horseface.org/iMac/3.png
iStat pro doesn't indicate anything shocking as far as temperatures go. During all of this glitchy madness, here's what it's showing:
http://horseface.org/iMac/temp.png
Note that the fan speeds are way high, but, again, that's because I'm forcibly raising them with smcFanControl. Interestingly, though, even when I'm not running smcFanControl, the temperatures seem to hover in a safe area. In spite of this, I'm almost certain it's a heat related issue. When I first installed smcFanControl and increased the speed of the fans, the iMac went from freezing and glitching on a daily basis to totally normal operation. There also appears to be a direct correlation between intensive usage and the glitching/freezing issue.
I have already installed all of the seemingly relevant OS X updates that I can find along with all of the other suggested updates. Nothing has helped, aside from smcFanControl.
So, my question is, what can I do about this? My computer is no longer under warranty. I'd rather not have to take it to Apple and have them charge me for the initial consultation and then whatever hardware replacement is required along with the cost of out-of-warranty service. I have already opened and disassembled this computer while trying to clean it. While it was a very daunting task the first time around (I really wish this iMac were as nicely designed internally as the first G5 iMacs!), I'm comfortable enough to go ahead and do it again, if necessary.
My educated guess here is that there is something wrong with the video card. Perhaps the onboard temperature sensor is bad, and that's why it's reporting safe operating temperatures but is behaving as if it were overheating? I'm not really sure.
Would it be wise to try to replace the video card? This seems to be the obvious next step to me, but, unfortunately, the prices I'm finding for the replacement parts are pretty outrageous. ApplePalace.com lists the 7300 as $188 and the 7600 $231. Is there anywhere I can get a replacement for less? Is this even likely to fix the problem? I really don't want to make such an investment and have it turn out that it's not going to help.
I don't know what to do. Any ideas or advice would be greatly appreciated. Thanks in advance.

Have you tried running Apple Hardware Test?
Your guess is most likely correct of it being the graphics card. I have a friend with the exact same computer same problem. It's not an over heating issue. A component is supposed to operate within certain values and certain temperature ranges. If a part has gone bad or is going bad it may not be able to produce those values at the temperature required. Maybe it can still operate within spec at a lower temperature. Even though temperature appears to be the indicator this does not actually mean the device is over heating rather the part is failing.
I have only been able to find one website that you can purchase the replacement graphics cards for this particular iMac and yes it's a bit pricey. My friend was quoted by the Mac Guys for about $250 including installation for the 7600GT card. Replacing the graphics card is really your only option unless you want to junk it and buy a new machine.

TouchSmart 600-1050 - Graphics Problem with MS Outlook

I have a TouchSmart 600-1050. When I open MS Outlook, and then open the Calendar in a separate window, the window opens as non-maximized and everything is fine. When I maximize the window (I start in Week view), the tasks below each day do not stretch to fit their now wider column. It's as if the graphics don't recalculate for that screen element. Once I am maximized and see the problem, I have to switch to another view (e.g. Month or Day) and back to Week and it will fix itself. Feels like a graphics problem, underpowered chipset or bug in driver (?).
This was not a problem on my HP Desktop I had before, and it is not a problem on my 3 year old Lenovo ThinkPad X60. All are running W7 and using Office 2007.
Any ideas? The graphics driver is up to date according to HP Update and Device Manager.
Thanks!

Thanks for your reply. I tried both of your suggestions and the issue occurred in both. I've never noticed the sub-content not maximizing properly in other apps, but haven't tested thoroughly.
Any other ideas would be greatly appreciated.
- Should I checked a different way to see if I have the latest drivers?
- Is there any way for me to upgrade my 600-1050 with the graphics card in the 600-1055? The 1050's "Mobile PCI Express Module" is open/available. Could I buy the nVidia GeForce GT 230 that comes with the 1055 and hook that up?
Only reason I suggest this is that the graphics seem sluggish to update at times.
Thanks.

W7/64-bit on W500 - Switchable Graphics problem

Hi,
Did a clean install Windows 7 Ultimate (64-bit) on my Thinkpad W500 (4062-3CG).
Having problem with "ThinkPad Switchable Graphics Driver for Windows 7".
ATI driver won't load, so default Intel chipset is used with poor graphics as a result.
I have also tried "Windows 7 BETA Drivers and Utilities" with no luck.
Yesterday the graphics worked for a short period of time, that was after remoting my Thinkpad with RDP? very strange. But after reboot graphics was back to non functional again.
Any ideas?
TIA
Johan

Did you apply Lenovo driver packages in any specific order? Don't really understand what I missed?
My plan was to do a "clean" W7/64 install and after that run ThinkVantage System Update 4.0 for latest drivers.
In my case ThinkVantage System Update 4.0 could not start without Access Help for Windows 7 installed, that was the first dependency problem.
However, after that ThinkVantage System Update 4.0 run successfully and everything works fine but the ThinkPad Switchable Graphics Driver for Windows 7.
The ThinkVantage System Update 4.0 applied latest updates for everything including the BIOS. When I try to run BIOS update separately for getting around the graphics problem it says BIOS version is OK and no update needed.
Tried to disable Switchable Graphics in BIOS-setup using Discrete but that does not fix my problem?

Hi
Tablet Lenovo S8-50LC
Wlan(WiFi) Does not work when use Sim Cart(3G).
What is the solution for this problem?
Build Number : TABS8-50LC_S000200_150121_ROW
SoftWarw Version : TABS8-50LC_150121

Right, but if you have the SIM in the tablet and you put the tablet in airplane mode, does wifi work then? If so, it may be a bad SIM. Do you have another SIM you can try?

I need help with an email WiFi sending problem on my iPad 2

I’m having an email WiFi sending problem on my iPad 2     Model: MC774C/A; IOS VERSION: 6.1.3 (10B329).
While I use 4 email accounts on the iPad -- Hotmail, Gmail, iCloud and ns.sympatico.ca ( a division of BellAliant) – the sending difficulty only relates to the ns.sympatico.ca. The settings for this account are:         pop.bellaliant.net            and      smtp.bellaliant.net
I first noticed the problem about 3 weeks ago while travelling across the country (Canada). (I do recall about that time there was an update of my IOS and I also for my wife purchased from the Bell store an iPhone which shares my Apple account.) Prior to that everything worked well for a couple of years.
I noticed earlier this month that the iPad received mail fine but would not send at night using the motels’ WiFi. During the day, using my 3G account, all worked fine. I phoned Bell but was told that my experience was normal so I thought no more about it until I returned home and found the same problem at the house. I called Bell again and worked for 2 hours with 3 Bell technicians who succeeded in getting the iPad to neither send nor receive and gave up advising me to take the iPad into a Bell store to have it looked at. I did that and the young technician got the iPad sending and receiving by changing the        smtp.bellaliant.net      to         mail.1xbell.ca
However, when I returned home again, I realized that it was working on my 3G and still doesn’t send on my WiFi
I’m looking for any suggestions that might solve this annoying problem?

Try this first - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.)
Or this - Delete the account in Mail and then set it up again. Settings->Mail, Contacts, Calendars -> Accounts   Tap on the Account, then on the red button that says Remove Account.

ITunes 11 wifi sync problem

Hi all,
I just update to iTunes 11, but since than I'm only able to sync my iPad and iPhone with a cable, the wifi sync option is not working. Both of my iDevices won't find my MacBook
Info:
iPad Wifi 3rd Gen
iPhone 5
MacBook Pro 15" (mid 2011)
Hope that anyone has a solution or Apple comes up with a solution

My itunes wasnt recognizing either my or my husbands phones via wifi either, I took the suggestion of others and reconnected to wifi, didnt work. What ended up working for me was going into network preferences on the mac, and than advanced and deleting my network from the list of preferred networks, turning on wifi on my mac, quitting itunes, turning wifi on my mac back on, reconnecting to my network and opening up itunes. Just synced a song to my iphone via wifi no problem. Odd workaround but hopefully that helps you. I am running osx 10.8.2 and my phones are on ios 6.0.1

WiFi (WLAN) problem - in the same room a iOS 5 device connects, iOS 6 not

Hi all,
I won't say that it's a proof for the iOS 6 WiFi/WLAN problem. BUT, it's evident that my iPhone 4 with iOS 5 sees all WLAN-networks and connects - my new iPad with iOS 6 doesn't! And I'm using the two devices in the same room. In addition my new iPad didn't have connection problems before updating to iOS 6.
Apple Software Engineers - please help and release the next update to fix it
Best regards
