Battery operated George Nelson Ball clock running slow

Adjust the pendulum bob so that it is a bit longer - there must be some sort of mechanism to change the position of the bob. That will slow it down as it swings.

This can be very frustrating, I know. Problem is that the clocks in later model vehicles are electronic. A low battery is not likely your problem. These clocks will operate correctly as long as your electrical system has the output of a flashlight battery, or even less.

I recently had the same problem with my new Silverado truck. It would lose about 4 minutes a month and it aggravated my to death trying to change it all the time. I replaced my radio with built-in clock and it works fine.

Not to say that you should go through such extreme measures, but it is sure nice to see the correct time.

It sounds like you may need to repair the movement.

it runs of the vehicle battery ,

Give the pendulum a shove and do it every time you pass the clock. I got mine going from swinging for just 20 seconds to working permanently, at least until the next battery change.

A near flat battery will cause the laptop to lose the time and date even if you change the BISO time and date, it will still lose time.
To get into the BIOS setup press F2 as you boot up the laptop.
Check the various settings and you will get to the time and date setting, follow the screen instructions to set the time and date.
I suggest you get a new battery installed before you change the time and date.

Is there a separate battery for the clock memory? If so I would try changing that. Otherwise the clock is probably busted. Digital clocks would not normally loose more than a few seconds a year. If the clocks crystal oscillator broke it may cause this. That could happen if the crystal was not glued down or came loose.
