Your Bios stttings are corrupted, you need to reflash the bios,,,,Download the new Bios fron the manufacturer and follow the instructions, they have to be downloaded, then burned to a cd as image, then disconnect the battery and power, insert the cd then push the Fn and ESC buttoms at the same time keep pressed all time then plug the power adaptor, the battery is not in the pc, make sure the batt is disconnected, then power the pc, the pc turn on but no display,, then release the buttons, leave the power connected, the pc in 2 or 3 minutes turn off, then back onin 5 or 6 minutes full functional, hope this work, good luck.. send email if you need a lil help in this matter.

Dear SIr,

Please consider checking whether the problem is not coming from loose battery or its power supplying unit.

Thank you.

take an eraser and try to clean the memory card with really works.
change the CMOS battery. Usually battery code/model is 2032 only same with the usual PC Board.
