Hi I had bought my laptop Asus A43S 3 years ago . ( still under the warranty period ) .

I recently just lost my warranty card somewhere ...

But I had registered my laptop online 3 years ago in order to extend the warranty period for one year .

I just wanna ask is it possible to grant my laptop a free service on cleansing the inner fan because it tends to get overheat very quick . I may not have the hardcopy of the prove but I have prove by signing up online

Hope to hear from you soon

Thanks
