Another lenovo (W530) doesn't charge a battery

Hi folks!

I was a happy owner of brand new W530 machine untill I mentioned that it doesn't charge the battery.

The machine came to me with 94% charged batt and since then it got to 4% mark.

 

Symptoms:

-Lenovo Power Manager detects the batt, says it's good and charging, doesn't estimate how long it would get to charge it.

-Windows power manager says "Pluged in, charging"

-W530 worked perfectly on the batt, I made it to drain the battery by unplugging power cord and running "heavy" applications.

-The battery indicator on top cover is flashing orange once per second.

-AC Power source outputs 20.5V, BIOS v.1.08, Lenovo software of the most current versions.

 

What I've tried:

-Uninstalling and reinstalling Lenovo Power Manager.

-Enabling/Disabling/Uninstalling "Microsoft ACPI - blah-blah"

-Unplugging power cord and battery, pressing power button for 40 seconds and assebmling all together.

 

Any working ideas are wellcome.

Re: Another lenovo (W530) doesn't charge a battery

Check the model number on the battery. If it's an older battery, then it will function in the computer, but will not charge. Maybe they accidentally shipped you an older model.

Re: Another lenovo (W530) doesn't charge a battery

70++ is the correct type (with the built in ID chip)

Re: Another lenovo (W530) doesn't charge a battery

Could someone be so kind to measure voltage between first and last contacts of battery socket?

 

I did it while computer running and measured about 0.38V, while I was expecting 11-12V.

My battery reads 10.8V and still loosing power.

Re: Another lenovo (W530) doesn't charge a battery

Hey Deff0,

 

Here is the page on your battery that was shipped with your computer in the below link:

 

http://support.lenovo.com/en_US/product-and-parts/detail.page?&DocID=PD024285

 

You should be getting:

 

ThinkPad Battery 70++ (9 Cell) (0A36303):

  • Battery energy (Watt-hours): 94 Wh
  • Battery capacity (Amp-hour): 8.4 Ah
  • Output voltage: 11.1V dc (nominal)

Have you called customer support and created a case? I would call them up and have one created and see if a battery replacement can be offered.

 

Best Regards,

 

Hiro

Re: Another lenovo (W530) doesn't charge a battery

The OP has the correct battery. You are looking at the "marketing" designation rather than the parts designation. Either there is something wrong with the battery id chip or the charging circuit. The designation on the battery is correct.

Re: Another lenovo (W530) doesn't charge a battery

I don't really understand what happened, but after my random magic movements around W530, it began to charge the battery.

 

I connected the battery to my laboratory power supply, adjusted it to 11.5V and left for an hour to charge (I used metal collar strays as contacts). Then I installed the battey back into W530. It still was 3%, nothing has changed. I shut the lid and got back to my 5year old VAIO, which has been working problem-free so far.

Several hours later I mentioned that flashing LED on lenovo's lid is GREEN, not ORANGE! I instantly powered it up and lenovo power manager showed 32% charge, 14 hours to full. HOOOORAY!

 

Hope I'll never have to complain about my Thinkpad.

Re: Another lenovo (W530) doesn't charge a battery

Out of curiosity, what is the voltage now between first and last contacts of battery socket? Before you said, "I did it while computer running and measured about 0.38V..."

Re: Another lenovo (W530) doesn't charge a battery

What have happened since my last post:

 

Note: Lenovo power manager used to estimate power consumption 60-70W even if W530 in idle state. I thought it's ok, w530 is a powerful machine with 170W AC adapter.

 

Lenovo was charging the battery very  slow (estimated 14 hours to full from 40%), with stops.

I was looking through this forum and desided to check if I have CUDA enabled. I launched GPU-Z and found out that K2000M was suspened. Then device manager showed me troubles with K2000M. I reinstalled it with fresh drivers and rebooted. Despite K2000M was functioning since then, power consumtion is floating between 28-33W (almost idle state) and the battery is being charged like it should (1% per 2-3min).

 

Now I may confirm that my lenovo works fine. 

 

BTW It's still about 0.35V between first and last battery contacts. Looks like w530 doesn't output charging current if it doesn't detect any battery.

 

PS Still no CUDA support Smiley Happy
