IdeaPad P500 battery question.

2013-01-18, 14:35 PM

Hi I am interest in purchasing Lenovo - IdeaPad Model: P500 – 59347559  laptop.

I notice reading the tech specification the laptop has a 4 lithium battery permanently installed.

From reading a review of this model on Google, a user stated he was getting only 2.5  hours of battery time before recharging.

 

Can someone explain what should be the normal average time of this battery before recharging?

Also 4 lithium seems rather small size compared to other brands(HP, Dell) having a 6 to 8 cell lithium.

Is 4 lithium that max size that can be use for this model? If no, can I upgrade it on my purchase?

 

Thanks.

TC.

hi tomx2,

 

From my experience, a 6 cell lithium battery can give you 2-4 hrs and a 4-cell lithium battery will give you 2-3 hrs.(depends on usage).

 

For the battery life, OEM's usually do a battery lifespan test from a 100% charge until the battery drains out. What they do is set the computer to idle & maximum power saving (setting power options to power saver, lower the brightness, etc.) then the recorded minutes from the test would be the maximum battery life. As for the usage, if you play videos, games, music non-stop then getting 1-2hrs battery life is normal. For moderate surfing and spreadsheet documents, you should get up to 2-3 hrs.

 

As for upgrading the battery, 4 cell is already the maximum capacity as this battery is a special design for the model (see page 40 of the hardware maintenance manual on how to replace the battery).. For charging, you can safely charge the battery when it goes down to 15 percent or less (about 2-3hrs of usage). To maximize the full potential of the battery, it must undergo 3 cycles (drain the battery then charge it back to 100%).

 

As per the maintenance manual:

 

Caution:

Only use the battery specified in the parts list for your computer. Any other battery could ignite or explode.

Hope this helps.

I now have owned a Lenovo - IdeaPad Model: P500 – 59347559  laptop for more than 1 year.  After burning through several memory chips, I have finally been able to upgrade to 16GB RAM.  Yet, the 4 lithium battery has been the worst - keeping up for 15 minutes max without electricity.  I have tried to discharge completely and recharge entirely several times but, am still encountering the same issue.  Also, as I run a private cloud plate-forme for digital forensics apps, I noticed several IRQs conflicts which shut down my environment upon critical activities.  I run Windows 8 with several "Classic" enhancements yet, given these persistent issues, I am glad that I run weekly the entire Lenovo One Key System recovery as well as daily gradual back-ups.  The device is nice and large so one can view much data and process fast but, my Lenovo X60 with Linux (which I bought nearly 10 years ago) remains more reliable than my P500.  I hope the Lenovo laptop architects get to read this note as I believe that there is room for more reliability - especially when one business is relying on the continuous processing performed by these devices.

that seems incredibly low for a run time on your battery perhaps it was defective from the begining? also ona off topic note windows 8 and since vista makes and uses virtual IRQ's so it is most likley your OS and not your hardware giving those errors also what specific IRQ's are you having issues with, you can in device manager under view select resoucrces by connection to see all your made IRQ's and which ones are conflicting with each other.

I own a Y510p SLI (retired), Yoga 2 Pro, X220T, P50 4K (sold), X1C5
