Laptop shut down due to errant battery. I was updating all programs on auto update option. Now all I have is a Grub> prompt. Where do I go from here.
Laptop is an NEC Versa and Ubuntu was working fine up until that moment without any issues.

If it is a grub rescue prompt, it is likely that grub cant find what is supposed to be booting. If it is just a generic grub prompt then it is likely something in boot files is messed up.
If you have a boot-cd that takes you into linux, I would suggest booting using that. mounting the drive under /mnt/my_drive, and running a chroot enviroment. the outline basics are bellow...
These commands require you to run them as a root/superuser, the prefered way to do this is prefix the commands with sudo , (alternatively you can use a root shell, created through running sudo -s). Which ever option you choose, beware, you can cause a lot of damage to your system using root, so use it with caution and sparingly.
sudo mkdir /mnt/my_drive
assuming your main partition is sda2
sudo mount /dev/sda2 /mnt/my_drve
then bind the /dev /proc /sys over to your hard drive
sudo mount --bind /dev /mnt/my_drive/dev
sudo mount --bind /proc /mnt/my_drive/proc
sudo mount --bind /sys /mnt/my_drive/sys
then move into a chroot environment
sudo chroot /mnt/my_drive /bin/bash
check that any package installations are configured
sudo dpkg-reconfigure -a
finally run the grub-install to repair the drive in question, often /dev/sda
sudo grub-install /dev/sda
and finally
sudo update-grub
