HP 2159m Monitor does not wake from sleep

[barney74060]

Try pressing the space bar to get it out of the sleep mode. Mine was doing the same thing and pressing the space bar was the only thing that would wake it up again.

Hi, I got the HP 2159m from a friend and I'm trying to test it, I connect it with my laptop by HDMI cable, the screen start at the beginning but after some seconds it sleep and none of the bottom work, although the audio is connected and work.

when I try to change the setting in the laptop the screen turn on/off with each change and the image appear and go after 3 seconds

Is it something wrong with screen or with the software?

HI all:

Thank you for your inquiry.

There are multiple possibilities for the monitor not waking after a sleep.

1. Video driver needs updating. Go to the manufacturer's web site for the latest driver.

2. PC bios - Many of the bios updates deal with fan, thermal and sleep mode issues.

3. Reseat the video card

Please refer to Big Dave's above post, re April 11,2010

It is an old post but I will also chime in:

Had two of these monitors on an older Vista system (never any issues there).  Moved them to a brand new Dell XPS8700 with Radeon R9 200 graphics board, Win 8.1 64b 

MOST of the time, no problem.  Occasionally however when returning from monitor sleep AND computer sleep (like first thing in morning) the primary display just has black screen. 

Amazingly, even the monitor power off/on button fails to respond.  I just unplug the power cable in back of the monitor and replug and everything works again OK.

BIOS and graphics drivers are most current.  Right now I had to say this is a driver issue that needs a fix.

Sorry to "necro" this post, but I seem to be having a slightly different issue from what I can find through searching the web and the various HP forums (Please let me know if you'd prefer I submit this in another thread).

My issue seems to be only when connected to my HP2159M via HDMI. No other display cable types (VGA/DVI/etc.) are connected -- only the single HDMI cable running from my vid card to the back of the monitor.

For a while, it seemed to be working well, with the monitor auto-detecting the HDMI input as it was the only connected cable that was therefore providing any sort of source signal.

Since those "good ol' days" when I got my new video card maybe 4-6 mos. ago, all of a sudden, the monitor started arbitrarily picking other source types like VGA and DVI without even checking if there was a signal provided through HDMI. I tried all the steps of changing the default source to HDMI, trying that with both "auto-switch source" or whatever it's called both ON and OFF, just to see if that was somehow bugged, then did a factory reset and did the same things.

I also tried another solution I saw on here in which you unplug the monitor (some variations also have you pull the HDMI cable out) and, while the monitor is powered off, depress the monitor's Power button for 60sec or more, afterward plugging everything back in. Still no luck there, even when I tried the previous steps of setting default source, etc. etc.

Another notable difference between my issue and others' issues is that, to pull signal from my HDMI cable, I simply have to hit the "Source" button on the monitor and select "HDMI" *every* time I power the monitor on. After I manually tell the monitor I want it to use the HDMI-in (the only cable plugged in anyway), it's happy until the next time I power the monitor off. It's literally EVERY time I power the monitor on that I have to do this. So in my mind, it seems that the signal is being sent OK from the video card and it's not a seating issue, but I'm curious to (hopefully) get someone's thoughts on this.

If not, I took my chances by resurrecting an older thread, but figured it was worth a shot. Thank you to any/everyone who might have input on this.

Thanks a ton,

Rob

Hello, my problem is similar except that I can see that monitor wakes back up because there is a small border around the outside of the black screen that is displaying the output of my PC.  Has anyone seen this behavour and come up with a fix?

Thanks!

I have had the same problem and recently discovered that I can unplug the monitor power cord and plug it back the monitor awakes.  Still can't figure out hoew to correct this

Hi Rainbow 23, I don't let my computer go to sleep.  When I sign out I turn off the monitor but leave the computer running during the day.  When I turn the monitor back on, it will not wake even though the computer is still running.  When I unplug the monitor power cord and plug it back in, it will wake most of the time otherwise I have to turn off the computer and reboot

Hi @TonyG4,

Thank you for your reply, I'll be more than glad to help you.

I understand that you only turn off the monitor, still the computer will not wake up when you turn on the monitor.

This issue could occur if the bios is not updated.

In order to update the bios, please let us know the model number of the tower and the operating system installed on the computer by checking the links below: 

1. Product Model Number

2. Windows Operating System

3. Mac Operating System is installed 

You have a good day ahead.
