Question about HP Pavilion a620n (PC028A) PC Desktop

1 Answer

Monitor went into sleep mode after uncertain time. -> I am using Intel mother baord and Interl processor. HP 19" LCD monitor. I am facing problem with display. Display saying "Monitor going into sleep mode no input to display" any time. If machine was not started last couple of days then machine can be in running situation for approx 2-3 hours and as the last woring time will be lesser (means if last time machine I worked on macine 30 min before and trying to start now again now then it will not start, means no display at all and may be display for 2,3 or 5 min if I emcountered the problem in last working session). Issue can come any time but it depends on last time working time difference to this time. As the time difference is increacing than the problem will come late. As the monitor goes into sleep mode first time, Imediate after if I will try to reboot (hard boot) it will not show any display. and if I will wait for some time then it may show for some time like 1, 2 min and this time will increase as much I will give time to rest my machine. 1. I think there is no issue with monitor (because I tried the monitor with my TV tuner card after this problem. It was working fine. 2. My mother board is in warrnty period I asked Intel if there is any issue with Board - No issue found. 3. I am not getting this time where exactly the problem is?? It can be SMPS problem. It can be heating issue. As some cell are got heat they stop working and after some time as it get in normal temprature. It start working prperly. 4. It can be UPS problem. My UPS is old ( approx 2 year) back up is only 5 min. I am not sure. cn any one suggest me. How can I resolve this abnormal problem. ;-( I m very much frustated. Please help.

Your monitor flashes due to a bad capacitors. They are responsible in controlling and regulating the power to the LCD. When they fail, this is the symptom 99% of the time.
To replace the bad ones, you will need to open, identify, desolder, replace by new ones and solder them back.
Job takes about 45 mins. (with soldering skills)
Price range for bad caps is 6 to 15 usd.

Here is artical I found on how to disable sleep mode on a monitor, this would be for VISTA or 7, if you are using XP it's a bit different. ____________________________________________________________ How to Disable Sleep Mode on a Monitor

Your computer monitor or laptop screen will enter sleep mode after your computer remains idle for a set period of time. You can disable sleep mode if you prefer the screen to remain illuminated. You merely need to change a setting in the Windows Power Management properties box.
Difficulty: Moderately Easy Instructions

  1. Click "Start" and "Control Panel".

  2. Click "System and Security" and "Power Options". This will bring up a new dialog box.

  3. Click the menus to the right of "Turn off the Display" and set them both to "Never". This will disable sleep mode.

Can you try the monitor on another computer? Also, make sure the cable is tight on the monitor side. And you also may need to replace the cable between the monitor and the computer.

Monitor resolution


Hello,

What do you mean that you were unable to get the native resolution of 1440x900? Are you saying that the resolution varries?

Since you mentioned that the mother board supports 1440x900, try to set the monitor resolution to that same resolution and then restart the computer.

If you will get the same problem, you have to make sure that the video card supports 1440x900 resolution.

No DVi input, then computer goes to sleep


Hi publicworker,

I had a similar problem whereas my monitor went to sleep mode after a few minutes. I'm running an HP LP 2065 in dual mode with another HP flat screen. However, I did resolve the issue after resetting the output settings.

How to do that:
  • right mouse click on the desktop
  • select graphic options
  • output to
  • extended desktop
Maybe some changings/modification will help you too.

Hit the keyboard keys. It is better to just turn sleep and hibernate off and just use a screen saver or tun it off.
