Dell D620 power issue

Question

Hi there, Please help, I have a dell latitude D620 that has run brilliantly for many years but has decided to stop working on me.

Regardless of the battery being inserted or not when the power cable is attached the battery light is glowing a constant orange and does not boot up. When only the battery is connected and I press the power button the orange battery light flashes. I have 2 chargers and 2 batteries and regardless of which I use it will not turn on.

I have re-seated the ram in both the front and rear and also re-seated the HDD to no avail. Is there anything else I can check?

Whether it helps or not but for a long time the battery would only ever charge when the laptop was switched off and a couple of times while it has been running I have connected the power lead and the light for the battery has turned orange, after re-seating the connector it would be OK (This actually happened the last time of use after the laptop took a small tumble and I did not realise power cable became disconnected so when it signalled that the power was low connecting the lead the orange light came on so I had to re-seat it) since then it has not worked after doing a standard shut down.

Please help as I don't want to wave bye bye to my trusty old laptop.

Flashing orange = Bad Battery.  There is no FIX.  New Battery.

Thanks SpeedStep, but why will it not start up without the battery installed the battery light is on permanently without the battery and will not boot up?

Depends on the model. If it has NVIDIA chip its because the motherboard is Dead.

Can also be the Reserve Battery AND can be bad power input socket.

KN248/ 0KN248 Reserve Battery

Last but not least possibility is that the Power Adapter is 65W not 90W and or it is Bad Also.

These systems at least in my area are cheaper to buy another than fix.

Hhmm thanks, food for thought.

I have the original power lead and a later model one both at 90 watts. Could be however the back up battery or the input for the power source (but then it would mean that it would still power up on my batteries again, one 6 months old non original and the other an original).

Will look into the back up battery and hope that the mother board is not knackered, if so will buy a non working one of ebay and combine the two as I don't want to get rid of this brilliant machine.
