Hi, I'm working on a Inspiron 9300 all I did is taking it apart and attempt to repair the audio connections but I could not get to the jacks so I put the laptop back together again and at boot up comes up with this error ****manufacturing mode: level 67 **** Press Fn-X to return the system to normal running mode. After about a minute I get Warning! Battery is on a critically low. Press F1 to continue. Internal HDD HARD error! WARNING the battery cannot be identified. This system will be unable to charge this battery. Continuing without F1/F2 ERROR attempting to boot from Onboard NIC Option ROM copy failed. Press any key to continue. Nothing happens, I tried F2 for and to get in to BIOS and I get to another screen with the chose to boot in to BIOS but it gets stuck and dose nothing. . Thanks in advance this is my wife’s laptop and I'm in dip doodle. “The lack of knowledge in time of performance equal stress”
