Since I recently had my Pavilion M7-1015dx serviced for a defective USB port - the one directly adjacent to the CD-drive, the drive has exhibited this annoying behavior of popping open at seemingly random intervals. Each session begins with the drive popping open upon boot, then anytime a media session (audio/video) of any kind on the HDD is begun, it begins a series of sporadic instances of popping open. HP flashed the BIOS online, but to no avail - the problem persists. Ir can pop open as often as 15 times during an hour's use, but the number varies from 0 to this upward limit of 15 or so. This unit has been serviced now 4 times for various problems, even though I have exercised extreme care in my possession. I know other owners of this model who are problem-free. I love this unit's features - it answers my needs perfectly, aside from these service issues. I am beginning to wonder if this is a "lemon" unit - not the model, but this particular unit. I am reluctant to send it away yet again for service, since this disrupts my business each time. How may I resolve this - is unit replacement an option? It is still under warranty until October 2013. I am somewhat disillusioned now with HP now given this unit's multiple issues, though online chat has provided ready, if ineffective advice. This unit is one of many HP laptops I have purchased, and the only one with this level of unresolved service issues.
