With the constant power cuts at work in the evening's I need a way to switch my computer on from home.

We all power off our computers on the weekends to save power costs as well so this can help.
I have enabled Wake on Lan from S5 in my bios.
I have enabled Wake on Lan on the network adapter in windows.
Allow this device to wake the computer.

Tried sending "magic packets" from PC, Android app, iPad 2 app but PC doesn't come on?
 
computer needs to be sleeping / hibernating.... not off. ; )


so change BIOS to go to sleep / hibernation state after power failure.

WOL works even if the PC is switched off (shutdown). There is no difference between a PC that is hibernating and one that is switched off (as long as as you didn't switch off the PSU too).

Hemps, does your phone/iPad have access to the LAN IP address of your office PC?

You'll need to send a broadcast packet to the broadcast address of your office PC's subnet.
eg. if your office PC's IP address is 192.168.10.2 with subnet mask 255.255.255.0, then you'll need to send the WOL packet to 192.168.10.255

I haven't used WOL yet, so I can't really provide much more help here.

okey...you can set bios setting to resume from power outage.we do it in server based pc's.will come on and boot windown soon as power is back on.
if u ping a pc on a network (with WOL) even if its off it will start up.windows doesnt control Wol.only motherboard.it keeps network controler active and checks for ping's to ip specific number( think im correct.) that's how my pc works.
can set auto wake up at specific times also in bios just make sure cmos battery is still ok.otherwise mobo looses info and settings sometimes when power goes off...

I think ping 192.168.10.255 will only ping PC (192.168.10.255) not whole range? only shows single ping on my CMD

ANY IT GUYS??????WE NEED YA
 
Wake on Lan packets are broadcast and contain the MAC of the targeted machine,but there are many factors that could be preventing it from working as intended. Some machines can only wake from specific states ( power off / sleep / hibernate ) but not necessarily others or all of them. Try testing with a packet sniffer on the machine and a tool like this

.255 is the broadcast address. You can't allocate .255 to a pc.
