if i pay my laptop using 0% instalment plan, can i claim the full amount of the laptop up to RM3000? or I can only claim for the instalment amount paid during the tax year?

I'm more towards to claiming up to RM3,000. If say i only allowed to claim the instalment paid, then it means i will need to claim the instalments paid in second tax year (which is against IRB rules of ONE claim per 3 years).
