Hello Bleeping,

 

I hope this is the correct forum.

 

I have a robot program that does on-line trading with my eMachines desktop computer. Windows 7 is installed.  It can sit for weeks at a time with no intervention and will run while I am out of town.  Occasionally, I need to remotely access to make updates.

 

I have two questions.

 

1.  If I were to experience a power loss, the duration of which that exceeds the capacity of my UPS, how can I get the computer to auto start once power is restored?

 

I imagine I can list the trading program as an auto-run after reboot, and it doesn't require a manual log-in each time.

 

2. What is a good remote access program to use when the desktop is up and going?

 

Several years ago I subscribed to a VPS and they charged for $40/month.  There was a large latency factor, and they really didn't supply much memory without charging extra so I dumped them. Not really worth $480/year.

 

Thanks!

  I've been using UPS on both computer center and VHS/DVD combo center for some time.  I'm not sure if auto-start is a good idea, especially when UPS also has been brought down [battery discharged].  If certain storm or other power conditions exist, and UPS has been temporarily compromised, damage to the computer's "drive-chain" [power supply, motherboard, memory, etc.] is a possibility.

  Is there anyone at home when you're gone for the most part?  And, is it possible to train that person to reset UPS, recharge the battery [at least making sure UPS is working and recharging], and finally to repower/repost/reboot computer?  When the computer finally comes to full desktop -- then restart the online trading program?

Nope.  No one home, maybe for weeks at a time.  That's why I'm looking for automatic.

I still do not recommend away-from-home auto-start.  However, do what you believe is best for you  :)

Accepting Roland's reservations about the advisability of such a process of automated re-starts, it would not be too difficult to design a piece of electronics to do this if you have any expertise in this field or have a friend who does.

 

Your computer is a desktop so it has an on button which needs to be pushed to start it. This button actually shorts two contacts together and this could be done with a remote relay or switch. You would need some means of detecting the presence or absence of your mains electric supply. This can be done by either sensing the presence/absence of the 60Hz field around any piece of mains wiring or directly by the presence or absence of the 110Vac itself. I am assuming here, since you are in the same time zone as Roland, you live in the USA. It would probably be a good idea to build some sort of time delay into the re-start so that your UPS has a chance to acquire some volts, say 10 or 30 minutes. I am thinking here that the absence of mains voltage would arm the device and that its restoration would trigger the re-start process.

 

Safety note - if you were to build such a device using the direct presence of the 110Vac supply it would need to be built to higher safety and installation standards than if you were detecting the 60Hz field.

Yep. No way around it. I'll have to cogitate on that one for a while.

 

Thanks guys.

I'm not sure if auto-start is a good idea, especially when UPS also has been brought down [battery discharged]. 

When the line voltage is restored the UPS is ready to pass line voltage through to the computer.  The UPS will be recharging the battery/ies after the line voltage has been restored.

You're correct, as long as the UPS auto-starts, computer is good to go.

@RolandJS

 

I'm not going to speculate on this.  If I have the information I need to research this UPS I can determine if it will autostart.  Most manufacturers recognize the necessity of this feature, especially is a commercial application.

You're correct!  UPS have auto-start.  In the back of my mind I was thinking of OP's desktop -- which the power button has to be physically pushed in to rePower, which no UPS can override that.

That looks great.  I'll try and make that one work.
