Monitor Goes into 'Power Saving Mode' HDMI

I have an LG monitor (IPS237-BN) which always goes into 'Power Saving Mode' when I connect my MacBook Air to it via a Thunderbolt-HDMI connection.
Sometimes it actually connects and I can mirror my displays (or count it as another), most of the time it doesn't. I have used different cables etc. I cannot install the driver because I do not have a CD drive.
Any help is appreciated, thanks!

Hi,
Update the the video driver from the NVIDIA web site.
Your PC bios should be 5.29 or higher so that is something to check.
The Truckee motherboard was recalled but you might be past that date.

Unable to restore screen when laptop goes into power saving mode

Toshiba Satellite M45 running MS Windows XP, When laptop goes into powersaving mode and screen goes black, if i do not move the mouse in a nanosecond I am unable to restore the screen. Try my ususal fix of pressing the now amber mechanical start button, but I only hear the computer start to whir, but the black screen continues. I have to do a hard close and consequently loose all unsaved data. Then do a mechanical start and return to the desk top with a message that the computer programs where not closed properly.
I have been told I need to change the power saving mode options. Is this correct? How do I do this? Thanks, Blooming

I tired to do a system restore for two different dates and got a message that MS was unable to restore to that/those dates. - no explanation.
Linda, sometimes the restore points get corrupted. The fix is to turn System Restore off and then on again. Unfortunately, that removes all the previous restore points.

New LG Monitor Screen Image Keeps Shifting a few pixels left and right / goes into power save mode

I just purchased a new LG Computer Monitor from Best Buy today and hooked it up to my PowerMac computer. Shortly after setting it up, the entire screen image started sporadically shifting left and right a few pixels. And then, at seemingly random times, it'll shut itself down, going into power save mode. I checked the cables to make sure they were secure and they seem to be. Could there be some sort of interference that's causing it? Or would it be the graphics card? My computer is only a couple years old. Please help!

Do you have another computer you can plug the monitor into to test?

LG Monitor stuck in Power Saving Mode

I just purchased an LG W2252TQ LCD monitor and I am using a mini-dvi to dvi adapter and a DVI cable to connect to the monitor. My macbook detects the monitor, but when I connect it, the monitor enters "Digital Power Saving Mode" and is asleep. No picture whatsoever. - I saw another post who was having similar trouble and he solved it by using a mini-dvi to vga adapter, but I'd prefer to use a digital connection. Any help?

kiamatthews: I bought the same LG monitor for my daughter's MacBook and I couldn't get it to work. Then I read your post and resigned myself to buying the mini-dvi to VGA adapter. Luckily, I stubbornly tried one more time and after a bit of fiddling I finally succeeded in getting it to work. (My daughter has the same setup as you i.e. LG W2252TQ LCD monitor connnected to a MacBook using the mini-dvi to dvi adapter and a dvi cable connected to the monitor.) I'm a relative newbie to Macs, so I'm not sure I've remembered all the steps, but here goes.
When I first connected them, the LG showed the background from the MacBook, but nothing else (no icons, no windows, etc). Eventually I brought up system preferences - displays, and some sort of monitor resolution window appeared on the LG, but it was different than what was on the MacBook. The "displays" window on the MacBook did indicate both the MacBook monitor and the LG, which it showed as 2252TQ or something like that. Anyway, I checked a box labelled "Show displays in menu bar", which then put a monitor icon on the menu bar. When I clicked on that, there was a line allowing me to select "mirror" which I did. Immediately, what was on the MacBook display appeared on the LG. After I picked myself up off the floor, I was able to change the resolution for the LG to its maximum setting and after about 2 seconds of blank screens, it reappeared with everything working as it should.
I hope that the above description is sufficient to get yours to work as well.

Monitor goes to energy saving mode

I have a macbook pro 13" (mid 2010) and i also bought the mini display port to vga adapter from apple, one day the computer went to sleep with and external monitor plugged in, and when i tried to wake up the computer the display still in energy saving mode, y tried typing in the keyboard and clicking but nothing, I had to unplug the external monitor and since then when y try to plug any external monitor (i've tried with several) it always goes to energy saving mode. I have tried installing the Mini DP VGA Update but it doesn't recognize that there is an external monitor plugged in.

VGA Card - ATI Radeon 7200 64 SDR, built by ATI, so there are no problems with it.

Macbook pro goes into power save mode with dell sp2208wfp monitor.

I have a macbook pro and am trying to connect it to a dell sp2208wfp monitor, I am using a hdmi cord and it goes straight to power save mode. My mac works on my roommates monitor and his PC works on my monitor but my mac doesn't work on my monitor. I've read the other forums and have found nothing. One guy suggested plugging the mac into a power source still nothing, any solutions before I try and sell this thing on craigslist?

Had the same issue a few months ago when I tried connecting to external monitor, it is only possible to run external displays from a Macbook Pro while the power cable is attached, if you try and connect to external display without having the charger attached the external display will flash your desk top for a second and then your Macbook Pro will go to sleep. Hence connect your charger every time you wish to connect to external display, its not a problem with your Macbook Pro, it's just the way of Apple. Hope that helps.

Officejet pro 8500a power saving mode

My Officejet Pro 8500a goes into power saving mode too soon and too frequently. Is it possible to turn this feature, power saving mode, off?

Yes you can go into the setup menu, to preferences down to Energy save mode and turn it off.

W520 Docking issue - attached monitor won't enter power saving mod

When my W520 (Win2008R2) power management profile shuts the display off (after 10 mins, for example), the externally DVI connected screen no longer receives a signal, but the screen doesn’t go into power saving mode. Instead, the monitor stays powered on (the green power light normally turns yellow), and displays the message “Cannot display this mode”. It’s a Dell monitor, and this message appears to be a Dell message, nothing from the Lenovo or Windows.
It’s a new W520, and a new docking station – the ThinkPad Mini Dock Series 3 170W. The previous W510 and previous docking station ThinkPad Mini Dock Series 3 135W both worked fine with this monitor, and were able properly stop sending it a signal.
So…where do I start troubleshooting? Is this a Lenovo docking station issue? Are others having this problem?

hey DougWelsby,
welcome to the forums and for this is hard to say if it is the docking station or is it something else.
is it possible for you to test a different monitor with the docking station or to have test the current monitor of yours directly with the W520 ?
If you can, do reply back with your findings.
At the same time, do hop over to http://support.lenovo.com and crosscheck the download list and ensure all drivers (including bios) is up to date.

How do you turn off power saving mode on a Officejet 6000

I have 5 Officejet 6000 printer contected by using the ethernet port. They print fine when not in power saving mode. When they go into power saving mode and a print job is sent to them, they do not print. You have to power off and on the printer for the job to print. I need to turn off the power saving mode on these printers. Computers sending print jobs are XP and Window 7.

I am not aware of a way to turn that feature off completely since it does not have a front panel.
However, I suspect largely that the issue is with DHCP IP (automatic) settings. Printers in general, with some routers, have issues with DHCP and standby where they no longer communicate using DHCP information.
I recommend setting static IP addresses for any printer on a network as it prevents most network issues with printers from occuring.
Print a network configuration page by holding the network button for 3 seconds and then releasing it. A printout should be printed with the printers IP address.
Once that is done, enter that IP address into the browser on a computer as if you were going to a site. Once that is entered, go to that site and the printer status page should be loaded.
There should be a Network option at the top. Select that option.
On this page, somewhere on the left, there should be an IPv4 option in a wired section. Select this and it will give the option for automatic or manual IP setup.
Select Manual IP setup. Enter The IP address and subnet mask from the printout. You can enter the gateway and the DNS servers, but they aren't really used since this printer does not have any web functions.
Click apply and you should get a success message.
At this point, the printer should have a static IP address and the issue of it not responding after entering standby should no longer be present.
PrintDoc's post has similar steps for a wireless version of the same printer. The only step that would really be different is choosing Wired instead of Wireless on the setup page.

My 4500 all in one goes into power save and will not come out of it without pulling the power plug.

I have tried hitting the power button short and long, pushing every button, but it seems the only way out is pulling the power plug.
Thanks for any help.

HI
This is a known issue and HP is working on Firmware to fix this issue. This will be released soon.
So please use the workaround for the time being if the printer goes to power saving mode.

Mirroring LG Monitor stuck in Analog Power Saving Mode

I have a macbook from 2006, and just attained an LG L1900J LCD monitor. When I connect the monitor to my macbook using a DVI to VGA Cable attached to a Mac mini DVI to VGA adapter I get no picture on the monitor and the message "Analog Power Saving Mode" appears before the monitor goes black and then switches into sleep mode.
I have used the Switch application to try and fix the issue, and I have also adjusted the resolution many times as it appears my Macbook recognizes the monitor but an image just won't appear on its screen. I just ordered a Male to Male DVI cable and mini DVI to DVI adapter to see if a digital connection would work. Does anyone know if this will work or of another solution to my problem? Thanks.

So I ordered a Mini DVI-DVI Dynex adapter and Male to Male DVI Cable off ebay for very cheap, and to my surprise, this set-up seemed to shake the monitor out of "Analog Power Saving Mode" into "Digital" since its a digital set-up and now I have a fully functioning, mirroring monitor. So I would suggest switching to DVI to correct your issue.
