Question about Dell Latitude 830 Notebook

1 Answer

Battery will not charge. Need info on how Latitude D830 works plz

I am a technician for a company, and one of the clients spilled chocolate milk on his work notebook Latitude D830. I cleaned the system up, and miraculously, it still works! Though, there IS one problem.. The battery, unfortunately does not charge. The power options say it IS, but it stays around 35% power. When I plug in the adapter, the battery light flashes for about 30 seconds, and stops. So, the computer detects the battery, but is unable to put power into it. I tried another battery in it, and the same problem occurred. The only thing I can figure is that the part(s) of the motherboard that controls the charging process of the battery has/have been damaged, and I would like to know how it works, so that maybe I can fix it. Where would I find these/this part(s), and how do they work?

    Yeah, I figured as much. I cleaned everything, including the mobo, but I just need to know what and where to sod. I was hoping someone had a schemat drawn, or knew where to find one that tells me what does what on the mobo

You would need to get that part sodered, usually the charging parts or contacts on the laptop are sodered onto the power supply which is in turn sodered onto the mobo. Try cleaning the contacts inside the case as well as where the battery is.

Check your battery, it may have run out of charge. Even when your computer is shut down, the charge still dissipates, although very slowly.

What does the A Padlock mean on a Dell Latitude d830

If milk was spilled on the unit what might go bad besides the CMOS Battery and the battery pack for the unit?

HI there,

Actually, the most likely result of the spill would be damage to the motherboard itself as a whole, or any attached components the milk came in contact with.

Some companies on eBay give flat rate quotes with the guarantee that if they can't repair it, there is no charge to you. I use several different companies there for spill damaged motherboards. I've had good success with them.

The reason I stay away from local sources is because the equipment for properly diagnosing and repairing such damage is very expensive and it's just not practical to own the equipment unless you've made a decision to go into the motherboard repair business. It's fairly unlikely you'd find someone near you who is properly equipped unless you just happen to live near one of the comanies listed on eBay.

Of course, you'll incurr one-way shipping costs but it's a small price to pay to be absolutely sure of the extent of your damage.

Best Regards,

Dell Latitude D830 instant off whenever loud sound played

Either that or the battery is near the end of its life and when a big spike in current is needed it fails so the voltage drops and the processor chokes, instantly shutting it down.

It is possible the battery where the contacts from the laptop fit into or the gold colored contacts themselves need to be repaired. Worst case, the spill short circuited the contacts on the board, in which case you will have to replace the board. I would suggest really cleaning the gold contacts on the laptop and the small slots on the battery itself with a Q-tip with a little bit of rubbing alcohol on it. Please make sure both areas are totally dry before reassembling the battery.

Good Luck,
