If anyone has any idea how to fix this will be wonderfull b3cause is imposible 3 new laptops to have HDMI port broken or 4 hdmi cables to not be good and 1 new just buy it with 4k support and 5 tv's to dont work

Hi GaBI13,
You can switch on - off the wireless by pressing (airplane mode) F7 or Fn-F7. If this doesn't help you check that wireless device is present in Device Manager, is enabled and working properly (no arrows or yellow triangle present on device). If everything OK go to Control Panel-Network and Internet-Network Connections, identify the Wireless Network Connection. If this is Disabled, double click to enable it, right click and choose Connect. The driver for WiFi you can find here in case that you need.
Hope this will help you.

Lenovo b590 power management not working

Hello! I have a problem with my laptop, a lenovo b590. (pentium 2020m, 4gb ram, intel hd graphics): the Lenovo Power Management driver not working....
Is exactly the same as here, but, the only difference is that I use windows 8.1:
https://forums.lenovo.com/t5/Lenovo-3000-and-Essential/Lenovo-B590-Lenovo-Power-Management-driver-no...
As no one could solve the problem there, I thought it may be more visible now and someone can help me
So, how can I solve this problem?
Edit: I tried everything that was said there, to no avail ...
Sorry for my english..

i'm not sure if there's any suitable cooling pads for your computer but cleaning the fan could be another solution. it may work but it may also void your warranty.
due to it's probably hardware issue, at this point i don't think i have much suggestions for you.

Update to Mac OS X 10.8.4 HDMI Not Working?

Hi,
I have a 15" MBP Retina and after I updated to Mac OS X 10.8.4, connecting to a tv through HDMI no longer works.
I have tried different cables, different tv's. When I connect my Lenovo laptop to my tv through HDMI, it works. Thus, I know it's not a tv or cable problem.
What happens with my MBP is that when I connect the HDMI from my tv to my laptop, the screen flashes blue but nothing happens after. Nothing shows up in the task bar (ex. mirroring options) and nothing shows up on my tv (it has no signal).
I'm guessing the latest update created this bug. Anyone share the same problem?

Satego x200-21u - Remote and HDMI not work on Windows 7

Hey
I have a problem with win7 and the remote that was delivered with my notebook when i bought it
I installed all drivers from the toshiba homepage for win7. I also installed some of the winvista driver, like the webcam- and the touchpad drivers.
The only two things, not working are the remote and the HDMI-Sound output.
my remote doesnt work with win7. and if i connect my notebook to my flat-tv via HDMI-Cable i only see the picture but hear no sound.
I changed also the settings in the soundoptions in win7 from default to Digitalaudio (HDMI) but it doesnt work anyways..
can someone tell me which drivers i need to install these two or what i have to do, to make my remote and the HDMI output work?
thanks alot

Hi mate,
This is really strange to say because this notebook is a little bit older and therefore there is no official Windows 7 support I think...
Do you have yellow exclamation marks in device manager at the moment?
For HDMI I think chipset, display and sound driver should be installed. Maybe you can get one on the Intel page directly.
Make also sure that the newest BIOS version is installed on your notebook.

Macbook mini-DVI - DVI - HDMI not working with My 32" Vizio

Okay so my Macbook mini-DVI - DVI - HDMI is not working with My 32" Vizio. I've connected an 18 pin plus one slot DVI to HDMI cable to my 32" Vizio HDTV, this cable is connected to my macbook via a Mini-DVI to DVI cable, this one has 24 pins plus one slot on the DVI side. My Vizio display is blue, no signal, it reads. I'm wondering if the reason it's not picking up the display is the lack of pins on the DVI to HDMI or because I dont have any display options aside from screen size and color on my display menu. BTW I hit the detect display button and nothing happened.... I know I just wrote alot here but hopefully someone will read it and come to the rescue. thanks

Oops, I guess all I had to do was restart my macbook. I feel like an idiot.....all is well.

Lenovo A1 - Touch screen not working after digitizer replacement

After dropping my tablet and breaking the digitzer, I ordered a replacement digitzer from a company in China. (It took about a month to get it) After watching this video, I was able to install my new digitizer and it finally looked new again....well at least the screen!
But.....when I powered up my tablet, the touch screen wasn't working..... I emailed back and forth with the company and they told me to install drive program, and send me a link to a site with a video, this site may have contained more than the video, but it was all in Chinese and I couldn't figure it out even with Google Translate. So I started researching. I thought I would try and load ICS on it, I thought, "Whats the worst thing that could happen?" it wasn't much more than a brick at this point anyways.
I found this website that let me through installing ICS on it. I had absolutly no expectations...but IT WORKED!!!! MY TOUCH SCREEN IS NOW WORKING!!!! I COULDN'T BELIEVE IT!!!
When I was researching for this problem, there was absolutly no posts anywhere for "Touch screen not working after new digitizer". So I wanted to share my experience.

Yea you are correct.....it must be a hardware problem. You must contact service centre of Lenovo and get help from there.

Moderator edit: Moved post from General Discussion board, changed subject to match question, added system info from duplicate post.

Thx! This looks like a good link. Somehow I got it to work without any tricks, it just worked all the sudden. Frikkin computers! I'm very surprised I have to choose audio-source when I connect my MacBook to my TV, I naively hoped that this was going to work out for itself (magically) once I've connected those two and chosen screen output.

Lightening to HDMI not working after recent update

I recently updated my Ipad and now my Lightening to HDMI adapter does not seem to work. It was working fine up until the most recent update. I know that the HDMI cable works and all the other connections are fine b/c it works fine when plugged into our blu-ray player.
Has anyone else had this problem, or does anyone know how to fix this issue?

What recent update? The last Epson R220 update for non intel Macs was 08/19/10: http://www.epson.com/cgi-bin/Store/support/supDetail.jsp?oid=60202&prodoid=58654 761&BV_UseBVCookie=yes&infoType=Downloads&platform=Macintosh&x=21&y=13
What happens when you click on the EPSON Printer Utility which should be inside the Utility folder? Have you tried repairing permissions and restarting your computer? Have you read Epson's user manual and/or contacted their tech support?
I also have the R220 model. Besides using their drivers, I also use the Gimp drivers: http://gimp-print.sourceforge.net/MacOSX.php

K430/K450: here`s the SOLUTION to Lenovo Power control switch not working anymore.

If your power control switch isn`t working anymore BUT you didn`t unistall it or erase some of his files, chances are that over time some software/update took control of some setting used by the Lenovo switch.
If this is the case, before reinstalling the software, try the following:
1 - Check your power plan option, if is on something else than Lenovo change your power plan option (scheme) to Lenovo Power Scheme.
2 - Access your pc advanced startup setting (win+x) check for the services LitModeCtrl and LenovoComService and set the two services to automatically start when the computer startsup. If it`s not working 99% is because some software (the most common is Samsung SSD Magician) has set the two to "Manual". Change to "Auto".
3 - Reboot and the Power control switch software will be working again.
I wonder why no one from Lenovo advice this, but i`ve had to find a solution myself after countless hit & miss attempts.

hi FlashOfLight,
Welcome to the Forums.
Have you tried performing a system restore to undo the changes? (by default, this feature is set to enabled)

Mckenzj14, welcome to the forum.
If you have Windows System Restore enabled you can select a Restore point to an earlier date to see if this solves your problem. In many instances this will work.
If not, is this your computer?

If I understand your comments correctly, you took the laptop back to place of purchase for service on a web cam issue and they replaced the main system board, web cam and added in dedicated graphics and you still have an issue with the web cam not working after minimal use.
Have you opened up the device manager to see if there are yellow or red bang marks on any of the listed items? Have you run Lenovo diagnostics? If there are no issues listed in device manager, you may want to echage the notebook for a new in the box model instead of a repair route.
Good luck.

Lenovo V570 SDcard reader not working

I got my Lenovo last year Aug 2011, and now the SDCard reader is not working.
How can I have it repaired? I have purchased support for it, and bought in Las Vegas, USA, but now I am staying in Singapore. When I purchased the laptop I have also confident it is an international warranty, as I am not a resident of US.
Thanks.

Computers sold in the USA *DO NOT* come with an international warranty. Best Buy does not sell add-on international warranty.
It wouuld probably be cheaper for you to buy and external USB SDcard reader.

Hi and welcome to the community!!
All the hotkeys combinations are controlled by the lenovo energy management software. So i reccomend you to reinstall/install it again. Its setup would be present in the lenovo drive of your hdd. If not then please download it from support site.
