the true also...even not authorized reseller also take the stock from authorized..and vice versa...this is business...making profit is the first place...for sure all item is come from manufacture and must go through distributor first...reseller authorized or not authorized also take same stock and mybe same source...just check serial number for validate the unit..no matter it come from China, US, Singapore, or Thailand...if got warranty...it will show in their database...

now u talk about lenovo or about toshiba?
some toshiba model cant claim here bcoz in local not selling same model...if selling same model sure can claim...even model number not same...thats totally different...i got a few cases....the nearest u can go to singapore...

but u buy for warranty or bcoz of spec? local model selling rm6k...US Model sell rm3k-5k...u choose...rm3k u can buy 2unit and the 2nd as spare part...rather than 1 unit...later got problem...also take a lot time for solve...even macbook pro rm8K sometime also got hardware issued....and lastly, its ur money...

toshiba, sony is manufacture from japan...lenovo+IBM, HP, Apple, Dell using policy in US...international warranty term from US company is different with manufacture from Japan...but not so much..only company/distri/reseller make it complicated...bcoz dont want give service to people that not buying from them....
