Aloha,i live in Kailua,Oahu and i now own a IBM Thinkpad X31 series Laptop and i'm just fairly new to this unit(laptop). Ineed everyones help to troubleshoot my system it works when i have the unit plugged into the outlet.works good no problem on that being used as a desktop. but i like to use as a laptop. When i unplug the system and run with a battery sometimes when it finishes booting up and i star to open internet explorer or anything sometimes it works but now it shuts down on it's own for less than a minute or two. the battery i have is fully charged. but i went and bought a new one thinking it might be the problem and it doesnt hurt to have a extra one. i fully charged it, tried it and then it shuts down. Ichecked the backup battry and it still reads good. i did not like try to leave it out for 15 minutes but will after this.so when it's plugged it runs without shutting down. i checked if hibernation time was short but i set it for 30 minutes. Thats all i had done so far. Please anyone help me figure out this issue. Mahalo for your time to read this and it's great to be a part of the family here learning from all of you. Crash
