Latitude D630 Power Problem
Problem: Battery shows 100% charged, but as soon as the AC cord is unplugged the computer shuts off, immediately, with no warning. It won't startup on 100% charged battery. Rebooting with AC cord plugged back in works fine, battery shows 100% again.
The battery is almost brand new, about a month or so, working fine until this morning. Wondering if it is possible that the battery is bad even though it shows 100% or could the problem be something else?

Go into BIOS setup - check if AC adapter and Battery are listed other than tagged as "unknown".
Most likely in this case the battery type is "unknown" indicating a communication failure with the battery.
Laptop and battery communicate quite a lot just before startup.
Take the battery to a similar laptop (that handles thus battery type) and do the same test described above.
If still unknown the communication failure resides inside the battery, otherwise it's a motherboard problem.

Hello,
I have similar problem. I bought my DELL D630 just two month ago. This is brand new, and the battery is new. But last week it just turned off. There is no battery identification LED flashing in the middle of application operation. I mean it just blackout. At that time the battery was almost full.
Unless connecting DC adapter it won't power up. At first i thought that there is a problem in a battery. Luckily, i have a friend of mine who has similar D630 laptop. His battery is also in good condition. So we changed our batteries. My battery worked normal at his laptop, but his battery did not work on my D630. It was like there is no battery connected.
The interesting fact is that the battery charge still appears in Status bar. I mean, it still appears, but after plugging out the DC adapter D630 just turns off immediately.
So i believe that the problem is in the laptop hardware. Maybe there is some fuse that burnt. Please, help me in this situation as soon as possible. I'm a student and the battery operation is vital for me. By the way: even in BIOS it says that the battery is operating normally.
I believe there is some fuse burnt off. Waiting for service response

There's no fuse on the motherboard which can be replaced. Either the laptop is not accepting power from the battery or the laptop battery is not releasing power to the laptop.
Does it show the manufacturer details? - See laptop battery information
Before power from the battery is released communication between laptpp battery and the POST controller takes places through the SMB. If correct battery info does show in windows or similar, communication infrastructure seems ok.
Is the lastest available BIOS version been flashed into the D630?
Be very careful upgrading BIOS - always follow instructions to the detail.
