It started to flicker on boot and not keeping BIOS settings. My brother figured it was the BIOS battery and ordered one and asked if I could install it since I knew the insides already. When I opened it up and swapped out the battery, on boot it gave me the screen flicker, two beeps and then goes dark. Also get the beeps with the original BIOS battery. The X40 will beep if a key is pressed.
The hard drive is still humming after the beeps (new 4200rpm 30GB HDD). Main battery is a good, I had bought a generic 9 cell on ebay for it. Original power pack. Tested with and w/o extra Crucial 512MB RAM. Lenovo says Two short beeps and a blank screen means System board or DIMMs. Any ideas of what to check / reset?

EDIT:
I plugged Thinkpad into external monitor, boots to BIOS w/o beeps. BUT, it gave the following error:
Code: Select all
Resource Conflict PCI network card slot 01. Bus 02. Device 02. Fuction 00
EDIT 2:
Googling, Error seems to be regarding the miniPCI WIFI card ( Atheros ). I have reset it, and also turned it off in BIOS but still not getting past black boot screen with Windows XP logo. I can boot to safemode, can't get last known working configuration to start. Any advice would be appreciated.
