Ok Nehaonline, I will let you what an SMPS is and will also try to give to more info on how to correct your problem.
First of all, SMPS means Switch Mode Power Supply. This is a device on your computer ( inside the cabinet, which you call CPU sometimes ). This is one of the main components of your computer, without it your computer will never run. All the components of your computer viz, motherboard, CD-Rom, Harddisk, etc are all connented to this SMPS to draw power. SMPS distributes power to all the components of your computer system. Hope u now know what an SMPS is. Below I give you the idle power ratings of the SMPS which we mostly use in our computers.
Case Size Recommended Wattage Min. +12v Max Load
Mini-Tower 330-350W 15A
Mid-Tower 350-380W 15A
Full Tower 380-450W 18A
Server Tower 450-550W 20A
Ok , now to explain this --> Mini Tower, Mid Tower, Full Tower, Server Tower simply means the size of the cabinet you have. Generally in our home Computers we use the Mini Tower or the Mid Tower, sometimes Full Tower also.
Now,next the 330-350W, 350-380W, 380-450W, 450-550W are the power ratings ( which we were talking about in the previous threads ) , Generally in our home Computers we have the 330-350W power ratings SMPS. ( U can see this ratings on the SMPS itself ).
Next, 15A, 18A , 20A are the Ampere ( u must have heard this word in school days during your science classess ) I will not go on the details on this now, but simply understand that this is the unit of current that is measured in electrical devices.

Well! It seems to me that u need also to check your power supply socket on the wall. Yes! On the Wall u have a Power Socket fixed to the Switch Board where u plug in the UPS Plug.
CAUTION !! WARNING!! : The following Tips require you to get help from your big brother or a knowledgeable friend who can handle electrical equipments.
U need to check the EARTHING of your switch board socket. To do this first prepare the materials required.
What is EARTHING ?
Ok Earthing is a familiar word but I will still explain it to you. The Power Socket on the Switch Board has THREE (3) holes, the top most large and single (middle) is the Earthing hole. Generally earthing is used to dissipiate extra electrical signal back to the earth (Mother Earth). Computer components produces electrical signal called Static Electricity and hence an Earthing Wiring is a MUST in order to use your computer and to keep it in good health.
Preparation : Collecte a New Bulb ( 60 Watts ) and a holder, wires.
Step 1: Connect the Bulb to the holder of the bulb, fix wire to it.
Step 2: Remove the UPS Plug from the Power Socket from the wall Switch Board.
Step3
ut one end of the wire inside the big hole (middle) of the Power Socket and the other to the small hole in the right (usually denoted by a capital
L) Now put the switch
ON. The Bulb should glow!
Setp 4: Check if the Buld Glows, if not , go to Step 6, if yes go to Step 5.
Step 5:Now check the brightness of the glowing bulb , does this glow the same as other bulbs in the room ( other bulbs means the bulbs that u can switch ON from the Switch Board just by a single switch ) if yes U do not have any Earthing problem. IF NOT glowing the same way (brightness) go to Step 6.
Step 6:U probably donot have proper earthing. Call an Expert Electrician to fix Earthing. This could be the problem for your UPS not to function properly.
Please Note : The above procedure is only to be carried out with professional help. I do not take any responsibility for any mistake of yours in following the instructions.
Please tell us if the problem was solved or not.
