System TurnOn Automatically

[anandharaja]

hi,
my system TurnOn Automatically without pressing power button. why?

[thetechfreak]

Can you provide more info if possible ?

Probably you switched it off once during boot and hence this is happening.
Try refitting the PSU cables.


a Virus may be causing this too.Period

mostly my system turn-on automatically. some time i manually press power button.
what info you want about my system configuration or what?

Recently i updated my BIOS. iam not noticed before updating bios how my system started.
Before updating BIOS when ever i switch on my UPS i noticed DVD,HDD, and Power LED are on, at the time i pressed Power button 2 times to turn on my system, iam not sure my sytem boot at that time.

Normally this happens when it's set in the BIOS to do just that. The exact location in BIOS and the exact wording in the menu may differ, but it's usually under something like "Power Management" and the sub-menu like "Power On after AC power loss".

Check the BIOS and if "Power On after...." is set to Enabled or On, just change it to Disabled or Off.

Have you enable power on upon network or keyboard/mouse activity?

Config looks OK. So the problem is not related to BIOS.
Well, provide us detailed info about your config. (I think its PSU, which is under-powering the setup. )

My System Config:

Intel DH67BL Mother Board
Intel i5 2500 Processor
Corsair 4GB 1600MHZ RAM
Seagate 1TB HDD
LG DVD Drive
Corsair GS600 PSU
CM Elite 310 Cabinet

Are you telling about these settings.

Wake On LAN From S4/S5 <Power-on Normal Boot>

[anshul_sood]

That too and my bios has settings for wake from keyboard and wake from mouse options.

[kiranbhat]

load default bios setting and check again.

put all jumpers in default position.

[anandharaja]

What is the use of this option Wake On LAN From S4/S5

[kiranbhat]

if you have 2 or more computers on lan connected then you can wakeup all computers from 1pc

[anshul_sood]

No problem.

Then for normal uses we don't need it & it should always remain disabled/off.

[kiranbhat]

ya mostly if we have server on lan then we need it,otherwise for day today use we dont need it

[d6bmg]

^ Thankfully very few of us got server, so its useless.

I didn't quite understood why turning System On by default was a problem. Isn't it good that you don't have to press power on, when you switch on the Mains!
It should be the problem, when System would have been turning off randomly!

i don't like to turn on my system automatically.

Almost everyone wants to have more & more control over his/her own system. So, automatic start-up of system is really annoying.
