For those with a defect in the DELL laptop motherboard charging circuitry there’s a possible workaround to charge laptop batteries externally. Have a look.
It’s no secret the battery charging system design for certain DELL Inspiron and Latitude laptop models isn’t as robust as it should be. Apart from failure of the ID chip in DELL AC adapters, the equivalent charging circuitry of the laptop motherboard is also known to fail. Mitigation of this failure usually requires an expensive motherboard replacement.
Specially for those with expired warranty there’s a possibility to charge DELL laptop batteries with a standalone laptop battery charger. Although the solution isn’t perfect, it saves a replacement of the motherboard.
DEKCELL, AGPTEK and MOREWER produce standalone laptop battery chargers for DELL laptops. The chargers are equipped with a special laptop battery connector.
Also have a look at external laptop battery packs - a solution used by US Military and Government.
