I picked up a 600E from my IT teacher's office as a "useless junk" for free today.
Fortunately it is complete with every parts except for the ultrabay drive. Coincidentally I have a spare ultrabay FDD, so I installed it, and the 600E looks pretty good now.
Plug in the AC power using my 701C's adapter, switch on, well, at least the LEDs turns on, not a complete junk
The battery indicator keeps blinking orange, which indicates a low or dead battery. Then the beeps come. Two ?long? beeps followed by one short sharp beep(quotation marks because I am not sure if they are long beeps; they are just longer than the later beep). The HMM says nothing about this. Help!
PS: The former owner/seller put a "T61P" sticker on the lower left corner of the LCD assembly as well as a core 2 duo inside and a ATI Radeon graphics sticker on the palm rest. Was he trying to "convert" a 600E to a T61p? Ridiculous.
Edit: I noticed the backup battery is missing. Is there any compatible backup battery from other models, e.g. old T series?
The screen is blank during beeps. Is it possible that the screen is defective?
