I bought G450 laptop in April-10 and after 20 days LCD display started flickring (likes waves) and graphics dispersed. Service centers has replaced its Motherboard, LCD dispaly, LCD cable, Adaptor, Battery etc. but still problem is same. It works for few hour after repairing and then same problem. it has visited 4 times to servicecenter for the same problem.
If anyone knows the solution for the same, pls let me know.
