Computer remains in power saving mode

Hello,
I am trying to connect my laptop to a monitor. The monitor worked fine with a pc when I last used it, a while ago. I have recently used the same laptop with another monitor, and that worked fine. But those two together... the best I managed was to get the monitor to show me the laptop's desktop for 2 seconds before going back to safe mode. Any idea what's going on??
Thanks in advance!

My PC turns on the light lights up the monitor just says power saving mode and then just turns off and sits there.
Removed the RAM and carefully cleaned it with Eraser.
I also removed the CMOS battery and replaced after a minute or more but I can't get away with the issue here.

PLEASE HELP

My monitor does not have a remote. Since my computer does not come on screen how do I shut off power saving mode

Hello,

I wanted to know how to turn-off this ECO settings. Its on on my TV for some reason. But when i try to change that a message appears : The screen will turn of after 3 seconds" or something like this.
I´ ve read other threads on this topic, and you recommand Head to Picture > Energy Saving.
When I do that, there are all the options, yet when i press aroow up or down, the screen shuts down again with the msg mentioned above.
Its not a new TV, I have it rather long time.

Thanks for any reply, Paul.
