It is common for people from non-technical backgrounds to be using computers these days, who often encounter hardware application problems. A common issue is exiting power saving mode. The computer enters power saving mode and the user cannot exit. In most cases, the problem lies with the motherboard's battery. To resolve this issue, the user needs to open the PC and locate the motherboard. After removing the battery, the system needs to be restarted. The reason the hardware was not responding is because the battery on the motherboard is old. After replacing it, the user can then exit and set their computer's time and date.
Can't exit power saving mode
Hi, I've just got myself a brand new Dell desktop XPS420 with Vista on it. Everything seemed to work fine, but my computer has started to enter power saving mode at completely random times while im actually on the PC.
For example, I might be in the middle of writing a document when suddenly my screen goes blank and says "Entering power saving mode". Then the green power light on the monitor turns to orange-ish. When I try to wake it up again, by either pressing keys on the keyboard or moving the mouse, nothing happens. Pressing the power button (or monitor button) doesn't help either and the only thing I can do is hold the power button down in order to shut my computer down and reboot it. This happens a lot and I have no idea how to solve it.
I have tried changing all the power save mode settings to "off" in BIOS but that didn't help either. All Windows updates are installed and running and I haven't installed any other programmes yet.
Can someone explain how I prevent my computer entering power saving mode? I would also like to know how to exit that mode, since that doesn't work either.
It seems to be a motherboard battery problem. Try this:
It is unlikely to be the monitor which is in power save mode. It is the computer itself.
When you cannot get a computer out of power save mode by any other means, typically the cause is that the button-cell-type battery of your computer, located on the motherboard, is empty.
Usually, this happens on a computer which is a few years old since its batteries will have run out after such a long time. (The motherboard battery is used to store various settings when the computer power is off, such as date and time. When your computer detects this battery is empty, it goes into a low-power mode).
The solution is to replace the button-cell battery on the motherboard of your computer:
- Open the case of your computer;
- Visually locate the motherboard (the main electronic circuit board) of your computer;
- Visually scan the motherboard for a button-cell battery (it looks like a digital watch battery but a bit larger);
- Remove this battery from your computer;
- Restart your computer: it should now power up normally (you may get some warning messages during the start-up sequence, but ignore them);
- Set the date and time of your computer using the "Date and Time" control panel;
- You can now use your computer normally but you will lose the date and time settings when you disconnect the computer power cord since there is no motherboard battery present to store them;
- Take the motherboard battery to an electronics store and get a replacement, then install this new battery in your computer;
- Restart your computer and set the date and time again; the settings will now be saved using fresh motherboard battery power.
