Acer 5715Z ICL50 with Vista OS
While trying to flash the BIOS, this computer appeared to lock up. The user tried CTRL+ALT+DEL and nothing happened. The screen continued to show the rolling icon. After a long while, the user pulled out the power converter; there was no battery installed at the time. Since then, the computer will not power on. The user tried the discharging, holding down CTL+I/O button. Still nothing.
There is no emergency/rescue disk.
How to proceed?
All help greatly appreciated.
