Your English is certainly better than my Polish! You need to change the CMOS
(RTC) battery.

Open the memory cover on the bottom of the machine and the battery is
immediately apparent. CR2035 if I remember correctly.

Take out any extra RAM(from the small cover underneath) and try a restart. If
it starts fine, then the RAM is bad. Thats what it sounds like is the problem.
Bad RAM will prevent the 770 to POST beep.
