My machine went through Power for warranty service...

My machine went through Power for warranty service because it complained about hard drive damage. The machine worked flawlessly otherwise. After servicing, the battery stopped working at all and did not update the drivers but pulled the machine. During the service, these drivers had been changed (this became clear as I examined the machine more closely). I advertise this because I think it would be the responsibility of the service company to fix it. The answer was that the battery has come to an end and can be replaced at XXX. So, during the service, they destroyed my computer's battery and are now trying to fund me by offering a new one. I will never recommend this company to anyone and I will never do business with them again !!! Lousy activities !!!!
