Yes, I paid ~ RM250 to upgrade the warranty from 2 years International Warranty to 3 years on site warranty.

As I said, Lenovo Malaysia don't offer on site warranty to all the consumer laptop models. As far as I know, Essential G series is definitely out, Y series is definitely in, the rest you have to find out for yourself

"get the warranty extendion a the point of purchase" - Sorry don't understand I bought the upgrade at the point of purchase. I had to registered the upgrade online with Lenovo. The warranty status when I check online at the time of purchase was 2 years International warranty. After registration, after ~ 3 weeks (I can't recall the exact time), when I checked online again, the warranty status was changed to 3 years on site warranty.

I actually bought it from 1 of the reseller at LYN garage sales forum here He is just a normal re-seller (selling lots of other brands), definitely not a Lenovo Malaysia branch.

May I know who is the seller? Btw, how can I tell a grey from an official Malaysian unit if the model sold in Malaysia?

I think ytlay sifu already answer the 2nd question.
The 1st question, let me pm you Not suppose to peddle ware or promote sales here

for the international warranty. actually which brand of laptop is supported. as for oversea uk. which brand is more better and easy?

Actually all brands offer International Warranty, just that some come standard, some you have to pay more to get it
Most models by Asus come standard with 2 years International Warranty. Asus UK warranty support is OK.

Yup, technicains at your door to service you 4 times within 1 month is soooooooo bad, it is unforgivable
Get a grip with reality

+1, if you were to have the exact same problem with other brands, say Asus.. its 4 x (2 months for each repairs) + an exorbitant phone bill + high blood pressure 

well, Dell can do no wrong      anyway, thanks for all your advices and opinions here. appreciate it...
oh, i have no idea what to expect since this is my first time buying laptop/branded computer, as my very old custom-built/no brand desktop just died guess mine is an isolated incident/unlucky... anyway, thanks for the input...

Thanks for clarifying ! I am planning to buy a y500 or z500 laptop. Looks like should be able to upgrade to 3 year warranty then?

HP and lenovo i dont know.

but for dell, their service default are onsite(no carry in), so with valid warranty, then there will be onsite.

lenovo got carry in policy so im not sure about that
