Tried to flash bios on my thinkcentre A55 PD. Now it's blank screen on startup and beeping.
Tried remove the motherboard battery and back again. Still the same...
I used this http://www-307.ibm.com/pc/support/site.wss/document.do?sitestyle=lenovo&lndocid=MIGR-67223
Is it wrong version? Any way to resolve this?
