hello, new to tech spot, i have a e-machine t-5082, i boots to the e symbol and thats all. moved drive to older unit and it tried to fix start up problems so i assume it works. micro soft screen came up. tried a different psu from a working unit. read an older post about the battery--3.7 volts.can't get to safe mode, no start up disc. any ideas will be entertained, thanks, steve
