Re: Flex 3-1580 Battery Charging/ Power Issue

2019-08-30, 2:05 AM

So, did replacing that 1275C work? I've got a device with the same issue here, and I need to use it once more. I can't tote my PC around.

And I suppose I would need more than a hobby-grade soldering iron?

Hey @JLopezC

Hobby-grade soldering iron can work, but hotair gun is better.

 

Anyways, the issue wasn't the 1275C, but the bigger embedded controller. Unfortunately, I haven't managed to replace it yet, as it is much more difficult and I messed some stuff up while trying to switch it.

I have been struggling with the "plugged in not charging" issue for a few months. I noticed that the power level was dropping. The laptop was below 20 % battery power and I was getting very concerned that I was going to need to replace the laptop. Just on a lark I decided to go to the battery section of System settings. I turned off "battery saver". Immediately I noticed an increase in battery power percentage. SERIOUSLY. Ater an hour or so my battery is now at 99%. This confirms many ppls suspicions that somehow software or updates are responsible for the issue. Could some bug in the software just be causing the issue?

@treysis What indicated that the other controller was the problem? And which embedded controller is it, exactly? I may have a suitable hot-air gun.

@JLopezC

It's drawing a lot of current (well beyond 1 Amps) and therefor getting very hot. Even when the device is powered off.

Looks like my issue might not be a controller after all. The charging indicator light reacts when I fiddle with the battery's connection to the motherboard. I could have a weak solder point, which might actually be fixable.
It is a four-year-old laptop at this point, and a four-year-old Pentium at that, so I'm looking for a new laptop as it is, but I don't have a replacement just yet.

Could you please indicate which "larger" controller you suspect of being the problem? Thanks.

The embedded controller NPCE285. But no idea why it broke. So there might be more defective chips.
