could start. If the indicator light is out but the fan inside still runs, then definitely there’s something wrong with your laptop hardware.
Solution:
1. Take off the battery and start the computer only with power adapter.
2. Pull and plug memory again, clean the golden fingers with an eraser.
3. Change a RAM and test.
4): Failure caused by BIOS and solution for it:
-First format the USB disk with FAT format.
-Download the latest BIOS (http://sites.google.com/site/maclesblogspotcom/), and copy two files FLASHIT.EXE and BIOS (*.fd files) to the root directory. Renamed fd file is ZG5IA32.FD, this is quite important.
-Close AA1, make sure the two batteries are connected with AC adapter. Press Fn+ESC and don’t let go, start the machine, push the power button. After leaving Fn+ESC keys for a few seconds, power button would flash. And then press power button. Then AA1 now begins starting BIOS flash (Refresh BIOS), don’t interrupt it in any case. After a period of time, power button would stop flashing, and AA1 would restart soon. Please be patient.
BIOS already appears, all settings are set default value.
-Restore successes.
Notice: power could not be cut during the process refreshing BIOS.
