You can file ITR for AY 2014-15 (FY 2013-14) by 31st July 2014 , you can also file a belated return for AY 2013-14(FY 2012-13) till end of march 2015.
Claiming depericiation on laptop etc are available only if you are pursuing business using the named assets during the year for which you are filing the return.
Go through the https://www.incometaxindia.gov.in/download_all.asp to find out which ITR you should file, if you have any question then please reply back to this post with the detail about what all sources of income you have then I can point you to the correct form.
