Omni 10 Charging Issues

[trustin]

A few days ago, I thought I had banished all the gremlins from my Omni 10 (thanks to this forum; the trick was disabling all power-saving options in the Intel display control panel and turning off power management for the USB controller).  I should have remained skeptical, as the tablet stopped charging soon after.  A call to HP Support resulted in a new adapter being shipped my way.  My FedEx package came today, and the only thing inside was a region-specific plug insert; no adapter to be found.  Seriously, HP?

Anyway, on to my question for the community, because I don't believe the adapter is the problem:  Has anyone found a solution for charging issues?  The tablet charged every time I plugged it in for more than three weeks, but has refused to charge for the last two days.  As far as I'm aware, no software changes were made near the time the problem appeared, and I see no evidence of failed hardware.

I don't think it needs to be said, but obviously I checked to make sure the adapter was plugged into a functioning outlet.

Maybe you have disabled a power option that was needed for the tablet to charge.

I thought about that, but I believe it's a separate issue.  I was able to charge several times after making the configuration changes I described.

After I posted this question, I examined the charging port and the adapter plug with a flashlight.  I can't see any damage, but the connection appears to be a very fragile design (large tolerances and small contact points, with little to ensure proper alignment).  Maybe a new adapter will solve the problem after all; that said, I expect many users will have similar problems over time.

I heard the charging connector is very fragile, small and thin. It could be what you said, that it loses contact. While you get HP send you a new adapter, try touching a little the plug of the adapter until you notice it makes contact and begins charging.

I would also suggest trying to play around with the connector to see if you can make contact. Also you could try to measure the output voltage of the power supply / charger.

Had the same problem over the past few days. Device would be plugged in and no charging.
Tried a different adapter and had the same issue.
Shut the machine off and it started to charge again.

Hello,

Did you get a replacement charger, and that didn't work either?

I have had my Omni only a few weeks and now it recognizes the charger as plugged in but says it isn't charging. If I turn it off it seems to trickle charge but so far at the rate it is going it will take a week to fully charge.

It worked great, then this, my first thought was the charger.

I have two chargers and neither worked until I rebooted.

I never received my replacement charger, even though the "support" person promised to straighten it out.  Hooray for outsourcing with zero accountability!

I didn't follow up on it, because my original charger mysteriously started working again.  I had rebooted many times with no improvement, but it started charging after several minutes of plugging the connector in at slightly different angles.  I didn't post an update to this thread, because I can't clearly identify what resolved the problem.  It's pretty obvious that the connection is a bad design; if you have problems, I'd recommend messing with it and/or rebooting until the problem disappears.

Did you Omni recognize that the charger was even plugged in? Mine does. I think it is charging barely. I have messed with a bit but there doesn't seem to be any play with the plug. The only thing I noticed was if it is plugged in at the bottom of the tablet and plugged into the wall it seems to be getting some power. If I unplugged just the wall part it still says the same on the battery but then immediately gives me a low power warning.

I think I will attempt to chat with a support specialist...
