I have a lenovo w510 with no harddisk and 2x2gb memory,if I put the adaptor and press the power button nothing happens,no light nothing,does it require a harddisk to power on,or is something broken?

No, it doesn't need a hard disk installed to power on. If you've got access to a multimeter/voltmeter I'd check the A/C adapter to determine if it's putting out power. If it has a battery installed, remove it as well - sometimes a faulty battery installed will prevent the system from turning on.

I purchased a one tb harddisk,put it in,no power yet,i tried 3 different adapters,still no power.

If you can verify that one of those A/C adapters is working (and you've tried turning it on without the battery), then it sounds like the motherboard might be toast.

Sounds like a power circuit issue and/or a dead MB. The chance of having 3 power adapter not working is pretty remote. I'd start taking everything apart and see if it post to BIOS, beep or do something beside playing door stop.

It seems all three adapters where broken,now it is at the repair shop,i am awaiting answer if they don't screw me.
