If the charger run the system fine without a battery then it's not a charger faulty. I don't think a bios update will solve the issue. Try to run without a charger(battery only) then without battery(charger only).

It makes NO SENSE AT ALL to update your bios if it was previously charging the main battery correctly !!

Laptop no video (or video problems), and battery, AC adapter, power jack T shooting.

See response 1:

If there is nothing wrong with your AC adapter or it's connection and the jack in the laptop.......

Laptop main batteries usually work as they should for a year or so, then they begin to rapidly deteriorate. From what I've seen, by two years they cannot be charged to anywhere near their full capacity, and it gets worse after that.
They often develop internal shorts when they are older. If the battery gets HOT rather than just warm after you have attempted to charge it for at least a half hour, or after you have been using the laptop for a while with the AC adapter plugged in, it's definitely internally shorted and you must replace it. Internally shorted batteries getting too hot have been known to cause the laptop to catch on fire.

Tips about battery charging problems on Dell laptops - may apply to other makes.

My original charger the dell plug with blue light broke of. i.e. wires broke off my son trying to fix must have shorted the battery. so I also replaced the battery but the new battery won’t charge new adapter works fine. and runs the laptop. I have been told that it is the bois, not recognising the Ac adapter, that cause this problem, and when I look at the bios screen, pre start up is says no AC adapter present. So will upgrading the bios from A01, to A08, help. Thanks for any help you can give, ( I will never buy any thing else with a dell logo on it )

"I have been told that it is the bois, not recognising the Ac adapter, that cause this problem..."

That's Bullxxxx !

Some people think every problem can be cured by updating the bios version !

Flashing the bios is the riskiest thing you can do with a computer !

You are taking a big risk when you flash your bios - if the flash fails, and/or the flash chip physically fails while flashing (this is COMMON - these cheap flash chips can only be flashed an unpredictable small number of times), you will have a mboard that will not boot.

If the flash fails, but the flash chip is physically okay, you can follow a specific Recovery procedure, according to the brand of your bios.

If the flash chip physically fails you will have a dead mboard until that is fixed, and you need to obtain a new flash chip, already flashed.
Most if not all laptops have a soldered-into-the-mboard bios flash chip, not a flash chip in a socket that can be removed. In that case, the flash chip can only be replaced by an expert with the proper de-soldering tools and usually you must ship the mboard to them and have it shipped back - that can cost more than you buying a good used mboard for your model.

IT MAKES NO SENSE AT ALL to update your bios if it was previously charging the main battery correctly !!

The most likely things are....
You may have the problem mentioned in the last part of response 3 - Dell usually has a Service manual available on the their web site for your model or model series that tells you how to take apart your laptop properly - or you may have a problem with the jack the AC adapter plugs into that needs to be fixed..

If you can't fix whatever's wrong, you could use a 12v DC to 110 AC inverter with the AC adapter when you're in the truck, e.g. plugged into the cigar/cigarette lighter socket.
