just to update. on the overall warranty experience.
**make sure laptop/desktop is in front of you with internet connection

1 --call the hotline no
2 --key in option --- warranty parts replacement
3 --the Rep will ask for service tag no / your details etc / state ur problem
4 --he will ask to go to dell.com.my and install like a team viewer software
5 -- after that he will run all the required test ---accordingly
6 -- if problem still persist ---they will hand over to parts replacement--- parts and replacement will give you a call to make appointment to come to your house/office
7 -- wait for them to come and repair/replace parts.

so far a good and easy experience , though im not sure if they can talk other than english. say mandarin,malay or tamil.
