I've tried updating the BIOS with progressively older versions with the same result.
After the computer turns off, the only way to turn it back on is to turn off the PC at the PSU switch for 5-10 seconds, turn it back on then start up as usual.
Those things are the most frequent reasons something inside the laptop has been damaged.
......"...screen for the update came up,i did not look for it and i clicked on it..."Bios updates are NEVER offered that way.
The decision to flash your BIOS should not be taken lightly.
