Updated XPS 18 BIOS to A06, won't charge in cradle

Jump to solution

Applied the BIOS update A06 today, and on reboot received a message that the computer doesn't recognize the charger as a Dell charger (even though the Dell charger is attached to the Dell cradle as it always was), and that it might not be able to charge appropriately.  Sure enough, if left plugged in and used extensively, the charger doesn't charge the battery.  I've tried disabling and enabling the Dell battery life optimizer, and it doesn't make any difference.  The notification tray icon shows charging, but it doesn't charge, even when the computer is turned off.  

The XPS 18 recognizes the charger when it's plugged directly into the unit, and it charges fine when plugged in directly, but not when it's plugged into the cradle.  The cradle and XPS 18 contacts are clean and don't show any sign of corrosion, and I have made certain that the XPS 18 is seated properly in the cradle.

Anyone else having this problem?  The cradle is the Dell cradle, not a generic or third-party cradle.

Hi fellows with the issue "plug in ; no charging" on DELL XPS 18 - After some exhausting research I got the conclusion the problem is with BIOS 06 version. I tried to downgrade accordingly with the Dell support's recommendations and got the message "Your BIOS is the same or higher than this version" and I was forced to end the setup process - Through a chat with the Dell Support I had the confirmation that Dell does not authorize the BIOS downgrade - More than this; It has been suggested to wait for the next BIOS version!!! Unbelievable...

It was working fine before the BIOS update, so I expect that the BIOS is more likely to be at fault than the contacts.  I'll try to see if I can reflash the earlier BIOS.

I have a similar issue.

My XPS18 charges from cradle and does not charge if directly plugged in. In this case i can see "connected but not charging" message from battery icon

First of all I would recommend an ATX reset (remove all external devices, battery and charger) hold the power button down for ~30 seconds see if this helps.

Check in BIOS (F2 during dell logo) and see if the AC adapter is recognized with the correct speccs.

If you can try with other chargers if it makes a difference.

Check for any damage on the cable connector on both the end of the charger and the computer (this can cause no charge situations).

If this does not help it is either the AC adapter, DC-in and in the worst case motherboard.

Don't mean to hi-jack the topic

But I'm having the same issue with the charger not working directly plugged in. The battery indicator showing plugged in and not charging. But charges fine while in the stand. Not sure what is going on. I have not updated anything from Dell as far a software. I'm of the opinion that the plug in on the tablet is dead for some reason. I will check the output with a meter to make sure its outputting the correct watts, volts, amps. as per the charger.

Confirmed that the charger was working fine. It must be something with the inlet part of the plug on the tablet not making full contact with it.

Well that is just fantastic. Now it will probably take two months to get fixed if I send it in for repairs. That is just perfect.

One more thing to check, could someone tell me if there is a software switch that maybe turned off the power to the plug some how????

I have the same exact problem.

I have unplugged the cradle and plugged in directly to the xps 18 and it is now charging.

I am in pursuit to figure out what is wrong with my cradle.

I have a similar problem--it doesn't charge at all, or it charges but the computer gets hot while charging, taking hours to recharge.  This just started recently.  When I plug directly into the computer the battery charges quickly and doesn't overheat.  Also my battery doesn't last as long now, a loss I wouldn't expect with a six month old computer.

Any news? Mine just started doing the same thing. Not charging while in cradle, but charges if directly plugged in.
