I bought a dv4-2112tx hp pavilion laptop from matrix centre. The first day it self the keyboard stopped working hp repaired but did not give a replacement. Then I went to India I faced another set of problems1) spoilt monitor 2) not working USB 3) not working DVD drive 4) and other problems related to os for ex laptop blinking on start up. This month I.e in may 2011 I gave it back to hp Singapore to repair problems like faulty keyboard and DVD drive and asked them to give me some sort of assurance that my hp will last for another year or two since they have harassed me for the first year itself...to this they give give me answers like "we will see what we can do" and haven't got a call back from them...they have harassed me and caused me stress for the past year.the whole year I have been running to hp care centers to get my product repaired...I have spent my hard earned money...I need at least an complimentary extension in the product warranty
