In case of a blue screen problem, we at the Arcler desk suggest its user restart the computer or the laptop. If you are unable to find the appropriate manual, then download the same from the Compaq website. In case of recovering the laptop to its previous condition, then you need to insert either a CD OR DVD only if every other solution fails. It is suggested to diagnose the hardware if you continuously get a beeping sound. If you are facing a problem with resetting the laptop, it is recommended that the user should disconnect USB devices and AC adapter linked with the computer and once again reconnect the AC adapter. We, at Arcler desk, is at your service with highly trained tech professionals to provide you with a 100% effective solution.
