my desktop power light blinks amber light when i try to start it, and stops only when i hold the power button on for 10 seconds. i assume from other threads i should take it all apart and try to find the battery to replace? Since i'll be opening up the case, should i just disconnect the hardrive and somehow attach to my working computer to save all the information on it? is this easy to do? my new desktop is an asus essentio series with windows 7 while my old computer is windows pro.
