My Acer Aspire 5740G is not starting. Adapter light goes off after connecting to laptop. So, I checked the motherboard JV50-CP 09285-1M 48.4GD01.01M and I found a short near CPU, it is marked R44 --> 68.4R710.10G which is a SMD power inductor/chip choke coil. Can anybody identify the part's name/specifications?

Checked schematic ,but it is 'R44' which is '68.4R710.10G'. So what is the specification of this smd inductor/coil. For Ex. Inductance=4.7uh ,but Self Resonating Frequency(SRF)=?,Amperes=?.
