G580 Laptop battery charging slow

Hi I was wondering if anyone had any ideas, My laptop battery seemed to be going downhill as it only lasts 30 minutes fully charged and took a long time to recharge so I replaced it with a new one which was a longer lasting 8800mAh. I also replaced the charger with a new genuine lenovo charger. But the new battery still seems to take a long time to recharge so I'm not sure what it could be. Could it be any of these:I recently upgraded my CPU and RAM to make it faster, could it be draining the battery too much? even though it seemed fine the first few weeks after upgrading.Could the new battery take longer to recharge anyway?I also noticed it after cleaning the fan out. have I not put something back together properly? Any ideas would be grateful Many thanksDale

Hi Daleg,
Welcome to the Forums
As per the query we understood that you are facing issue with not powering on in your Lenovo G580 laptop.
Try to perform the battery gauge and check for the issue, to perform the gauge reset go to energy manager and select maintenance and guide option under this tab select gauge reset under battery gauge reset option and check for the issue.
Hope this helps. Do post back if the issue persists.
Best regards,
Ashwin. S

[SOLVED] Brand new laptop, battery charges to 95% max (?)

I've seen this widely on a simple google search for "last full capacity",
the laptop has been used for just two days, but acpi reports:
koko@TravelMate ~ $ acpi -biatc
Battery 0: Charging, 100%, until charged
Battery 0: design capacity 4400 mAh, last full capacity 4182 mAh = 95%
Adapter 0: on-line
Cooling 0: x86_pkg_temp no state information available
Cooling 1: intel_powerclamp no state information available
Cooling 2: Processor 0 of 10
Cooling 3: Processor 0 of 10
Cooling 4: Processor 0 of 10
Cooling 5: Processor 0 of 10
it won't go higher than that.
Is that normal? maybe some sort of overcharge protection?
my previous netbook always charged to 100% or even a bit more than the design capacity...

Another reason might be wrong measurement [circuit] from either battery or laptop side. And the simplest reason would be that the laptop/battery was produced some time ago, depending on type of technology used, certain batteries lose significant amount of capacity over time (even if unused). Since it is brand new, get in touch with your supplier and get at least the battery exchanged.
If you try to discharge it first, do fully discharge it using LEDs or some other low current load until voltage drops to approximately 10% of nominal voltage, and then recharge it not extending 110% of time it needed to be fully charged Repeating this cycle might and does help with certain types of batteries. If I were you, I would not bother however and go get a replacement from the shop, unless it is really troublesome.
As for overcharge protection, there are usually thermal (usually the most important one), shortcircuit and overcharge (meaning overvoltage protection) protections built into the battery (usually one ic) and/or laptop.
None of that is applicable for Lithium Polymer or Lithium Ion batteries. They should never drop below 3 volts. Discharging them below that point will destroy them and risk a fire. Charging Lithium based batteries is also non trivial and requires tight monitoring of voltage and controls on current and time. Do not mess with LiPoly or LiIon, they truly represent a serious safety hazard if they are mistreated. I note that your suggestions and descriptions of shorted cells are applicable to some non Li technologies; notably Nickle based batteries (Nickle Cadmium, Nickle Metal Hydride, etc...) In general, those are not found in modern laptops because of their toxicity and relatively low energy density as compared to LiPoly.

Laptop battery "charging" but stuck at 0%

Hi,
I have a Pavilion G6-1b79ca and the battery stopped charging.
Windows show "Plugged in, charging" and the level stay at 0%. Forever.
Obviously it is now completely drained.
If I remove the DC plug the computer close immediately.
Here is what I've done so far, more or less in that order:
1. Replaced the battery (recommended by the BIOS openning page...)
2. Tried this popular fix:
Shutdown->Remove Battery and power plug->Hold "POWER" button 30 sec->Plug DC cable->Boot->Device Manager->Battery->Uninstall Microsoft ACPI-Complient Control Method Battery ->Shutdown->Put Battery in (Can't boot on it alone since it won't charge... but maybe that could help)->Start computer
3. Updated all drivers and reinstalled all HP utilities (got the Intel drivers directly from the Intel website)
4. I updated the BIOS to the latest version and reseted it to default settings
5. Tested the power adapter with a multimeter (Psu unloaded, referenced to outer ground sleeve it read 19.8V=Inner plug, 18V center pin)
6. Replaced the motherboard (which has been replaced already)
7. Replaced the PSU
8. Reinstalled Windows
9. Soldered the power adapter directly to the motherboard to bypass all contact connections (cut the DC plug and soldered the bare wires directly to the pcb)
The HP BIOS utility (F2 at startup) tells me that the new battery fails the test and need to be replaced. Awesome.
The battery test in the HP assistant utility (run in Windows) tells me that the battery is OK but would need to be charged (Seriously???? This is becoming funny...)
So basically the hardware is brand new.
Windows/HP utility tells me that the battery is OK but the BIOS utility will tell me to replace it.
What the hell is happening????
The hardware is supposed to be A1 (fully replaced) and windows have been completely reinstalled.
Any suggestion?? My sanity start to fade....
On a side note, here is the situation I hope did not happened:
1. The original battery failed
2. It burned the motherboard charging circuit
3. I replaced the battery which then got damaged by the burned motherboard charging circuit
4. I finally replaced the motherboard which got damaged by the new battery, that was damaged by the previous motherboard, which was damaged by the original battery....
5. Back to square one, a couple of hundred $ less and a lot of time lost....
I can't see myself buying ANOTHER motherboard/battery combo without going crazy.....
Thanks for any help !
This question was solved.

IT'S ALIVE!!! Lolll!
The problem was the new battery, I don't know why but it was completely drained and never got to charge.
I ask the seller to replace it and to charge the new one a bit so I was able to boot on the battery only.
I removed the psu and the battery, held the POWER button 30sec and booted on the battery alone.
Once in Windows I pluged the charger and now it is fully charged!
Looks like the key here was to be able to boot on the battery alone. a thing I never could achieve while struggling with the drained one.
Hope this thread help someone to troubleshoot battery problems, since it contains a LOT of possible solutions.
Thanks to those who took of their time to help!

Battery charges for 20 seconds , then stops. Lenovo yoga 3

My battery started having sudden drains when in sleep mode. As soon as i woke it up it showed 0% left and shut down. I installed all the updates. The problem seemed solved for one day. Then it drained again but this time did not shut down. It kept going and when plugged in shows 'plugged, not charging' so i started the calibration. That was yesterday. This morning it is still running. I so do not want to send it back, but if there is no way to fix this I may have to
Moderator note: Post edited.Messages moved to this thread from https://forums.lenovo.com/t5/Lenovo-Edge-Yoga-Flex-Laptops/Battery-charges-for-20-seconds-then-stops...

I broke off the calibration since it seemed to be doing nothing at all, then let the computer fully drain.On stertup everything seemed fine for a bit till it then again failed to recognise the battry being charged. I gave up,and plugged in laid it aside. After a few hours opened it up again and presto, battery regognised, fully charged and now after a night in sleep mode 98% left and still functioning...

Battery dead within 10 days of use. Lenovo G580 Laptop

Recently I bought a new Lenovo G580 Laptop in the Emirates and after using it for 10 days, the battery got dead. I never used the laptop while it was on the charging mode and took complete care as it is brand new. Also used to charge it once in a couple of days. It is a disappointed since its a brand new machine. Anyone also facing this problem?

@manay,
Try removing the AC and battery then hold power button for 3 seconds, repeat this 3 times then put the AC and battery back and see if it helps.
Also try leaving the AC on and charge the laptop for the night. If problem persist then contact support to get the hardware checked.

Hi, I need help my computer is not starting up at all, nothing happening when I press the button on/off. The battery charger is working as using it for another laptop. Not sure what to do. Anyone have any idea? many thanks

You could try a SMC reset:

Does it harm the battery if we use the laptop while charging?

If we use while charging, is the power required directly taken from the external supply or from the battery itself. Which is the safest way to use the laptop without drawing power from the battery?

No harm is done. There is enough power from the adapter to run the laptop and charge the battery. There is hardware and software in place which prevents any problems. The laptop will not take power from the battery while the AC adapter is plugged in.

Nice try! Take a hike.

I can't turn on my MacBook Air despite trying to hold down the power button and using the SMC method. BTW my battery charger lights up to a green when plugged into the laptop.

Any way to prevent charging my laptop battery??

Hi all,I own Pavilion 6080se,I would leave my battery in my laptop,but I'm worry about it,coz I think I short my battery life with this,I think coz of draining 1 persent my adaptor charge it to 100% and with discahrge 1 persent again this proccess Continuing....So it ca make my battery damaged....
am I wrong??any sugg.? is there any apps to control battery charging??I mean any options to disable charging....
I use Windows 7 64-bit....
regards...

There aren't any programs to control battery charging for your laptop so it will always charge to 100%. Some business laptops (Lenovo and Dell) support battery thresholds and disabling charging.
the battery can become damaged over time if the computer constantly charges the battery from 99% to 100%. if you don't use your battery very often, you can drain it to 40-60% and remove it from your computer.
The battery can be worn down from not being used also. If you never use a laptop on battery, it may simply go bad one day. I have several batteries with very low cycles, and they don't work anymore. I also have a battery with nearly 800 cycles and it works perfectly.
HaggisCat: I don't understand where you're getting "you get an hour" from. Most laptops last around 2-6 hours with a battery that has little to no wear. Additionally, 13% is probably what you have your specific computer set to. The default tends to be around 4 or 5% when the computer hibernates or shuts down.

My ipad seems to now be using up the battery much faster. What do I need to check. Also seems to charge slow.

im not too sure about the slow charging, but i would recommend altering the way in which you use your ipad i.e turning your brightness as far down as possible, making sure you close all your apps etc... smaller things like that have a massive effect. my phone battery was awful at the start, however simply lowering the brightness has made it way more efficient and it has a much longer life.

What is the best charge/discharge regime for the laptop battery?

I have a HP G71 340US laptop with 12 cell battery of 8800 mAh design capacity.
It is clear, that keeping the laptop plugged, and always having 100% charged battery is not the most healthy regime for the battery.
I have found from the web that permanently charging and discharging the battery (like charging form 9% to 100% then back to 9% and so on) is also far not the most healthy regime for the battery.
So my question is: what is the most healthy regime for battery charging/discharging, assuming that the AC power source is always available?
It seems there in so software which can support such regime automatically, as charging cannot be stopped programmable, but maybe there is a software which can report corresponding alerts, informing that it is time to start charging or to start discharging?
This question was solved.

I need the mother board plug for the battery charger and Bios Battery for an XT178 Laptop?

HP xt178 Laptop (1P) F4685H SN: TW24604214
I need to replace the motherboard plug that the Battery Charger plugs into as it is broken.
The Bios Battery has failed and is NO: ML1220 with a number 28 in ink stamped on it.
are these parts available from HP or can you provide me with common part numbers.
Jack

Hey JD,
That's a reaalllllllllyyy old laptop. As an HP employee I feel obligated to recommend picking up a new one at your local retailer.
If you are serious about finding parts then you may be out of luck. HP stopped servicing that notebook in 2006.

Ugent: DM4-1160us laptop not charging battery when battery completely drained

Hi, all,
I bought it last year and, a month later, I found it does not charge battery when the
battery was completed drained. "completely drained" means when clicking on power on
button, the charging light does not even flash. In such as case, if I plug in the power cord
to charge the battery, the computer will stay in "charging, 0%) forever and the charging
light stays amber and sometimes turns into white later.
Computer can not power up without power cord plugged in. Battery dinostics said battery
is bad and gave an error long error code. HP suppport replaced it with a new battery. But,
I found later the same problem happened again.
Note: the problem only happens when battery is completed drained meaning
the charging light does not flash when trying to turn the computer on.
I suspect the computer itself is defective. Anyone has idea?
Thanks,
SZ

THIS IS THE SOLUTION AND IT WILL TAKE 90 SECONDS TO FIX
Power management software in Windows Vista
Understanding battery charging issues
If the notebook battery is not charging or the notebook does not indicate that the battery is charging, the most likely scenario is that the battery itself is operating correctly, but its power management software may have become corrupt. In order to correct the problem, you will need to uninstall and reinstall the power management software by using the Device Manager. This document will explain how to uninstall and reinstall the ACPI Battery listings in Windows Vista, as well as how to obtain and install updated BIOS files, if needed to correct other battery issues.
Uninstalling and reinstalling power management software in Windows Vista
In order to correct problems with the battery's power management software, follow the steps below.
1. Click Start and type device in the search field, then select Device Manager .
2. Expand the Batteries category.
3. Under the Batteries category, right-click the Microsoft ACPI Compliant Control Method Battery listing, and select Uninstall .
WARNING: Do not remove the Microsoft AC Adapter driver or any other ACPI compliant driver.
4. On the Device Manager taskbar, click Scan for hardware changes .
Alternately, select Action > Scan for hardware changes .
Windows will scan your computer for hardware that doesn't have drivers installed, and will install the drivers needed to manage your battery's power. The notebook should now indicate that the battery is charging.
