Hello, not long ago I tried to modify an original bios to unlock hidden menu, however without success. The bios I tried to flash it on, failed after operation was, so called, completed. Computer froze out and did not turn off itself. However after flashing there were one short and one long beep. I plugged it out from the power and soon after plugged it back in. Now there is no response to any keyboard combination and no lights flash / come up when powering. This is Phoenix BIOS. Tried several methods with USB stick recovery... nothing. No fans, no beeps, no lights, no nothing... Even battery charging light wont turn on. Are there any more solutions I could try without de-soldering BIOS? Do not have any floppies around and cant imagine how would I connect it to Laptop. I also did remove CMOS battery, no success... Any help / opinions appreciated, thank you. Sorry if wrong section..
