Main battery charges OK
Replaced CMOS battery (CR2025)
Memory check OK
Get IBM logo
Get ThinkPad logo (HD lamp one flash)
No beeps, just a single series of about 10 rapid pulses throught speakers then freezes.
OS don't load.
I turned off and retarted with F1 key held down.
Did not get bios screen.
Same as above starting with Power ON.
No beeps or error codes. just one series of pulses
(Win 2000 Pro is installed OS)
If I remove CMOS battery and restart I get Memory check OK then error codes 161 and 163 then go to Error screen. Click OK then to Time and date screen. Set Date and Time OK. Computer reboots. Get mem check, IBM logo, then ThinkPad and a few seconds later the string of pulses through speakers and freezes.
Can I request help on next steps to take?. MANY THANKS
