Vaio fit strange charge problem.

[AFR0N1]

I have a Sony Vaio fit 15 (SVF15A1C5E) and recently it will no longer hold a charge and it will be stuck at 0% plugged in charging. Vaio care told me that the battery health was critical. I opened CMD to check the health of the battery by using this command: powercfg /batteryreport

In the report I could see that the maximum charge capacity was well bellow the original max charge. (it was at 440 mwh)

So I decided that I should replace the battery with a new one.

I bought a new genuine battery and installed it.

The problem starts to get a bit weird now...

I installed the battery and I plugged in the laptop and turned it on.

It was stuck at 25% plugged in charging and battery health critical.

The next day.

I entered the bios and reset to default settings and then enabled then disabled battery care.

It charged to 100% and I thought the problem was solved...

Vaio care still said health was critical.

I disconnected the ac and the vaio happily ran on battery power.

When it eventually got to around 50% it suddenly dropped in battery percentage to 7%

I plugged it in and it got stuck to 25% again.

I unplugged it and it held its charge for a good amount of time.

When it got to 23% I plugged it back in.

It charged to 24% then got stuck.

I unplugged and let it eventually drop to 22%

I plugged it back in and then it charged then got stuck at 23%

The next day I plug it in while it's off for a few hours.

I unplug it then turn it on.

While it boots up

The power light is green.

The charge light is off.

And hard-drive light is on.

All seems good...

Until a second later (vaio is still starting up)

The power and charge light start to pulse with each other.

I thought maybe the battery was low so I plugged it in.

The charge got stuck again.

I unplugged and it was fine and the health was excellent.

I preformed another health report and in the report at 2:10 pm it said the battery was changed (when it wasn't) and it didn't show any charge capacity. (Maybe the battery disconnected it's self from the laptop?)

Then a few minutes later in the report it said the battery was changed again and it showed a charge capacity.

I did some research and I found some one with a battery problem and he said that the battery just needed to be re-seated. 

Today (time of typing) I decided to:

Remove the battery

Hold the power button

Re install the battery

Press the battery off/reset button.

Plug in and charge for around 1 to 2 hours.

I unplugged and turned on.

The above happened again.

While it boots up

The power light is green.

The charge light is off.

And hard-drive light is on.

All seems good...

Until a second later (vaio is still starting up)

The power and charge light start to pulse with each other.

I plugged it in and it got stuck at 8% plugged in charging.

I unplugged.

Power and charge light pulse.

Plug back in.

Charges to 9% plugged in charging and gets stuck.

I unplug again.

The power and charge light pulse.

I plug back in gets to 10% plugged in charging and gets stuck.

This repeats until I get to 13% plugged in charging.

It won't go beyond 13% now and if I unplug the laptop.

The power and charge light pulse together.

The laptop holds its charge.

Vaio care says health is excellent.

I have no idea what is going on any more.

Sorry for all the reading.

Please help if you can.

Here's a link to the battery report. (I don't know if it will work, it works for me though)

UPDATE:

When I unplug the power and charge light no longer pulse and it holds its charge.

It charged to 14% now.

It got stuck at 14% 😧

Update: I charged it for a few hours until the charge lights went out, indicating that the battery is at 100%. I turned on the laptop when plugged in and it was at 100%.

Great!

But the milisecond I unplugged the charger, the laptop turned off instantly. Like, it cut off.

I plugged it back in and turned it back on and then Vaio Care notified me that the battery health is critical.

Update 2:

I got another new battery and it seems to work perfectly.

Just one problem...

Vaio care still says the health is critical.

I found out that the battery was a fake. So its probably not properly compatible or bad quality.
