Hi, @BINNY The more you describe the problem, the more it appears to me like a power supply issue rather than a power management issue. As far as I know, all computer CRT monitors are designed to switch off their CRT when the video signal form the system disappears. Other than that, their CRT power is in no way controlled by the power management system of the computer. The monitor supply is directly connected to AC mains- even when connected to the rear of the SMPS. Besides, the cable that connects the monitor to system (VGA) is analog. It carries not much digital info. You can verify this here: http://pinouts.ru/Video/VGA15.shtml . All these indicate a serious issue somewhere in your power supply and the power management system is innocent. For now, however, I would recommend avoiding sleep mode till you get your power supply issue solved. And as for the frequent monitor on/off - its always slightly strenuous - but the monitor manufacturers take care of that. It won't cause any realistic damage.
And for the stabilizer - most manual stabilizer have a dial that is used to select a voltage range (ie, transformer step-up ratio). They still have an automatic negative feedback voltage controller element after that. I am not sure how this would affect a UPS connected to it- but, it wont be much different from when an automatic stabilizer is connected. So I still wouldn't recommend its use. Now the UPS- it is designed to isolate the mains and connect the inverted battery source when the voltage drops too low. This is not unusual. But if you are facing frequent mains drop, better get your mains and UPS checked. @ Yadu I believed you the first time you wrote that there was an 'insane' scheme. You didn't have to put the link up here to convince me :) . But still, thanks very much for the informative link. If you look carefully, you will find that the acpi kernel module was patched to make it insane. So it is very unlikely that any distro will use this 'insane' patch. But that link is important for me since it has some data for me to ponder over. @ nishandh Until recently, Ubuntu and may be other distros had some problems with power management- may be due to wrong sequence of power modes. But there was nothing that would blow up motherboards or crash and burn HDDs. Otherwise, many other competitors, including the 'all powerful monopolistic corporation' would have cashed on it.
