I have bought DV4-1131Tx notebook in December after a month of purchase I'm facing problem with battery backup and sometimes my lap gets shut down automatically even though the battery meter shows battery level greater than critical battery level. i have given my notebook in service center for more than 4 times and yet they fail to rectify the problem. I'm very disappointed with their service and now regret buying HP product and this is worst service i have ever faced with. I'm going to suggest every one not to buy Hp products here afte
