yes, it is very troublesome & same case happen to my company.
the funny thing is... when you claim warranty from shop, their supervisor can call thru dell and make replacement

did you think about why your online reseller take so long time to provide you the dell order number? why you need to claim direct to dell malaysia? cannot claim from your online reseller?

if you want to make sure what you get, MUST buy only from Dell Malaysia Authorize Dealer. dealer receipt provided is your proof of purchased and confirm recognized by Dell Malaysia. don't complain if you want to get dirty cheap product from grey market.

just to remind, there is many unauthorized online seller's stock are not source from Dell Malaysia and not valid for Dell Malaysia warranty support. Beside remove the order number sticker, some are even worst, they sell you ARB monitors with normal price and remove the ARB sticker but did not tell you the truth.

if you already bought, why not you share with us who is the online seller you bought from? maybe we can help to confirm if there is any background of the online seller?

if Dell Online are available for the product you looking for, buy direct. else, you can check Authorize dealer/partner here by location.

Well, I've seen a few "online retailers" on LYN claiming that their warranty coverage for Dell monitor is a standard 5 years coverage. The truth is, Dell do not provide standard 5 years warranty. Their standard warranty is 3 years. Not 5. If want to upgrade to 5 years warranty, need to pay additional $$$.

So I assume these online retailers are taking their chances/risk by promoting/selling their products with 5 years warranty.
Now question is, what is going to happen if your monitor fails to work after 3 years? My guess is, they'll probably take it to a local computer store to repair (if the damage is not related to LCD panel) and return it back to you. Or they will exchange a used/2nd hand unit for u.

Oh ya.. U guys are right about the service tag. Monitors below 27" does not have a service tag

Dell ultrasharp u2412m is only RM692 on the dell website.
