F&O query - laptop price

Hi,

Thanks for all your help in connection with taxation. Please see if you can help me with my query:

No salary income
Have some stocks trading in come

Recently, started trading in F&O and made some profit till now. Would like to purchase laptop with around 80000 for F&O trading use. Can my entire laptop cost be treated as business expenses for the current FY?

Thanks for your in advance.
