Dell inspiron 1545 charging adapter

Hello,

I am having problems with the battery charging on a Dell Inspiron 1545 laptop.

I bought this computer which had a charging issue. It only works on mains power the battery is not charging.

It was thought that the Charging jack board was faulty. This has now been replaced.

I am still having problems.

The mains adapter that came with the laptop was not original Dell.

I have replaced the adapter with an original Dell PA21. The end lead that plugs into the jack has a hexagonal end.

Does anyone know if this is the correct type for this model? Or should I have a round end type? Or does it make no difference?

I can only conclude that the problem lies in the adapter and/or the Dell battery that I think could be dead and may need replacing.

Thanks very much.

Malcolm

RE: Dell inspiron 1545 charging adapter

Some systems were built with hexagonal connectors - if yours has one at the computer end, the adapter should fit it. If not, you need the round connector.

That said, if the AC adapter isn't recognized and you've already tried a new adapter and a new DC jack board, the problem is with the mainboard, not the battery.

Thanks for your reply.

When I plug in the old adapter, The light on the front of the laptop alternates from white to orange indicating that the computer is trying to charge.

However, the icon at the bottom right hand side of the screen says; connecting but not charging.

When the correct Dell PA21 adapter is fitted, the icon shows charging, but the battery charge shows 0% and does not seem to increase. Also the light on front of laptop stays white.

I am uncertain about there being a mainboard fault.

Hence my original question about an adapter or battery problem.

If the system recognizes the AC adapter (F2 at powerup to check), then the adapter is OK -- and if the battery is original to the system, it is well past its expected lifespan and is very likely the faulty part.
