HCL
AUDIO not working both in speakers and audio jacks

I have an HCL leaptop z29 c20. From the start of my purchase I've been a lot of problems like speakers not working, lid loosen... I gave the system for service and spent around 10, 000 rs. But now again I've the following problem

- bluetooth device not working (I tried reinstalling the driver)

-lid s almost broken and loosen

-both speakers and the audio jacks not workin totally

Please provide me some suggetions...

I'm really fed up with the HCL products.
