Hey guys. I replaced a Lenovo Yoga 530's battery 5 days ago as it was kinda bad and would randomly die at about 30%. I bought the exact battery from PB-Tech and replaced it myself. After installing the battery I charged it up and it worked like normal. The next day I decided to calibrate it using Onekey Optimiser which turned out to be a big mistake. I started calibrating it at 8pm and started waiting for it to finish thinking it wouldn't be a long process and it was taking too long so I decided to cancel it. I later searched it up and found out it takes about 6-8 hours. I calibrated it last night and it took 12 and a half hours. It successfully finished and later when I tried using it, it died at 80%. Please help as this is a new battery. I'm thinking about resetting the laptop and if the problem persists, I'll send it back to PB-Tech as it has a 6-month warranty.

 

 

 

TL;DR: I replaced a battery, calibrated it, and now the laptop died at 80%. What should I do?

I'd have thought using calibration tools outside the standard ones provided by lenovo would be..dicey.

They have smarts in them these days to self monitor and adjust

A calibration should happen after you first try use it after a full charge while it monitors voltage I'd suspect.

Also, the latest bios and power updates by most manufacturing now cap charging to 80% of cell capacity..total. Think of it like a HDD with reserve cell capacity to lengthen lifespan. (And stop swelling complaints..)

There's no telling what bypassing that may do.

Well, Onekey Optimiser used to be one of Lenovo's main systems so I thought that'd work. What do you think I can do to fix this? Am I completely stuffed? Do you think putting the old battery back into the laptop, starting it up and then replacing it again with the new one would do anything or is that just a waste of time.

If it's not turning on. Do the last battery state clear
(Same thing as flushing a stuck s3 state these days)

Remove the power supply. Hold down the power button for a good 20 count. Release and take a few breaths

Put power back in, and quickpress.

No, it does a charge/battery state clear.

The charging circuits have smarts. As does the battery. To stop Li batteries... Exploding.
They talk to each other. And these days windows 10 doesn't really 'shut down'. It goes into a deep sleep state for faster apparent start-up.

Of which can get out of whack and the uefi bios will refuse to start or trigger protection.

Holding the power with no input source discharges the charging circuit and causes the current sleep/battery state to reset

Some have a pinhole button to help do this by temporary removing the battery power too

Others without, you just hold power while off.

Aye man, the day I did this the laptop died at 60 percent which was a great improvement. The next day I just put it on charge before 60% because I had unsaved work. And so today, I started the laptop up and it was at 50%, didn't put it on charge and it lasted till 20% and then it did the unexpected shut down again. I charged it up and used it but next it died at 60% again lol.

So there's been an improvement, but it's still unstable. I might reset the laptop and do the remove battery hold power button thing again.

Thanks for your help tho :D

uhhh the battery died at 80% 😳 and then 90%

When I plug it in to charge and start up the computer, the battery is 90% or above. I let it charge to 100% and kept it plugged in because I didn't wanna keep starting up the computer. After an hour or so the earthquake happened so I decided to take out the charger but the computer died in like a minute

So yeah

when you buy a "new battery", you don't know if it's OEM equipment or 3rd party. i am sick of 3rd party batteries that promises everything and delivers nothing.

 

every replacement battery i have bought have disappointed me, because of this. the manufacturer from the battery making country is making some very very poor quality rubbish that is not worth the paper that the invoice is printed on.

 

i now no longer buy replacement battery, i replace my devices.

The battery I got had the Lenovo logo on it and is nearly identical to the original which was in the laptop

They blurred the logo out for some reason but yeah

That battery is not produced by Lenovo. It says right there "For Lenovo" not "By Lenovo" or anything else - there's no branding.

 

Return it.

the battery itself says Lenovo on it, is it still off-brand?
