Hi kishan3, I would suggest you to perform system restore for the date the system was working properly. Click the link mentioned below to perform system restore: [URL] NOTE: System restore will remove the applications installed after the restore point. If the issue persists, Please click the link mentioned below which will take you to the drivers website: [URL] Enter the Service Tag of the computer and choose the Operating System installed on the computer. Please update the latest version of drivers and BIOS available. NOTE: Ensure that the battery is more than 30% charged and the adapter is connected during the BIOS update.Also, you may click the link mentioned below to open the drivers page for your system model directly:[URL]  Thanks & RegardsManshu S#iworkfordell
