Lenovo Z40-70 Battery

Hello,I have a Lenovo Z40-70 laptop. Can I replace the existing battery with a bigger one? Because the current 4 cell battery hardly works for 2 hours. If yes please help me with a link.Thank You.

Hi Premacharya93,
Welcome to the Forums
As per the query we understood that you are looking for battery upgrade in your Lenovo Z40-70 laptop.
As per the specification of this model it has supports 4 cell battery hence the upgrade of the battery may not be possible, as you have mentioned about the low battery backup try to perform the battery gauge, to perform the gauge reset go to energy manager select maintenance guide under this option select reset option under gauge reset perform this and check for the issue.
Hope this helps. Do post back if the issue persists.
Best regards,
Ashwin. S

Lenovo z40 screen not working

I have acquired a brand new lenovo z40 one month ago, and recently the screen began to constantly flicker. I have restarted the computer several times and ran a virus scan. I would like to know if this is a hardware or software problem, and how to fix it.

Hi Triangle,
From your failure description it sounds like you have a hardware failure it rests between the LCD Panel/ Module, or LCD cable. Please contact Lenovo Support and send it to a Lenovo repair depot so that we can take a further look into it and replace the defective parts in a timely manner ! Cheers

Lenovo notebook E540 Battery drains when it is not powered on

Lenovo Notebook E540 battery drains when it is not powered on. My colleague said that there is a cloud connection being connected during power off and it consumes power. Is that possible? Any resolution?

Hi Kingchechan,
Welcome to Lenovo Community!
As far as I know only the Windows update will be accessing to the server, or might be any other 3rd party cloud related application, which might be accessing to the cloud server.
Did you check disabling USB always on in BIOS & Wake On Lan from Windows AND BIOS
Check running command powercfg /devicequery wake_armed to see if any device is programmed to power on the laptop might be this is consuming battery power.
Best regards,

Lenovo yoga 10 battery replacement

I have a problem with my Lenovo yoga tablet battery. It is phisically damaged. I'm teaching in a school and one of the students has stepped on it in a weird accident. The bottom line is that the battery cable that connects the battery with the rest of the device broke. (I'm not sure what is the name is English of that particular cable I think is a I2c bus).I opened the tablet and I'm sure that is the device problem. I had actually no choice but to open the tablet because one part of the kickstand came out of its socket.
I would like to know if I can buy a new battery and replace the damaged one without actually sending my tablet to a shop. The battery seam to be embedded in the Enhanced Kickstand.
this is a pic of the type of battery embeded (at one of the heads there is a I2C-Bus that broke in two)

QUIERO CAMBIAR LA VELOCIDAD DE MI PROCESADOR DE MI LENOVO Z40-70...!!!

HOLA BUENOS DIAS...!!! MI LENOVO Z40-70 ESTA MUY LENTO DESDE QUE LO COMPRE... CUANDO LE DOY EN PROPIEDADES DE MI PC... ME SALE QUE EL PROCESADOR TIENE 2 VELOCIDADES UNO DE 1.70 GHZ Y DE 2.40 GHZ... Y QUIERO QUE FUNCIONE A LA VELOCIDAD DE 2.40 GHZ... COMO LE HAGO PARA QUE SU VELCIDAD SEA DE 2.40?! PORQUE YA INVESTIGUE Y LEI QUE SEGUN ESO LO HACE AUTOMATICAMENTE...!!! CONTESTENEME... PORFAVOR PORQUE PENSE QUE POR SER PROCESADOR CORE I5, LA LAP ESTARIA SUPER PERO YA VI QUE NO...!!! O DEVUELVANME MI DINERO PORQUE AUN TENGO GARANTIA...!!!

Hola xickoKDC que tal,
Si tienes un procesador i5-4210U la frecuencia mínima es de 1.7GHZ variable a 2.7 GHz, como bien mencionas es automático el cambio y esto es influenciado por la carga de trabajo que necesites procesar en ese momento.
Por ser procesador I5 no quiere decir que sea de los mejores, el que tu tienes esta por encima del promedio, donde puedes realizar varias actividades.
Considero que la lentitud es asociada a otro problema si puedes dar mas detalles se puede entender que tratas de manifestar con la referencia que das sobre lentitud.
Lenovo tiene su centro de llamadas para atencion a garantia, números al final en mi firma para poder contactarlos.
Un saludo.

Lenovo B590 discharge battery when off

Good morning, I've experienced very annoying problem with Lenovo B590 Laptop (20206 with HM70 chipset). Laptop discharges a battery (about 10% per 24h) when it's off (power off or hibernate).
I disabled:
- WAKE ON LAN settings in BIOS
- Wake on * in network adapter properties (LAN and WLAN).
- Allow this device to wake the computer (LAN, WLAN, Bluetooth)
Only option I found so far - eject battery for a second after power off. In such case, no discharge occurs.
I really appreciate, if you can help me with this issue.
Thank you!

Hi rinkar,
Thanks for posting and welcome to the Lenovo Community,
Can I ask you to Enter BIOS and Return the BIOS to the factory default settings by pressing F9 inside the BIOS and then F10 to save and exit,
And then please if you have Lenovo Energy management in your application list please uninstall Lenovo Energy management and restart the system and then reinstall it back from the below link:
Windows8:
Lenovo Power Management
Windows7:
Lenovo Power Management
Hope the information helps. Let us know.
Regards

Lenovo G550 CMOS Battery replacement

Hi, I have a Lenovo G550 which sometimes fails to start. If left for a few days it eventually starts up. When it does finally start there is a "check date and time" error on the boot menu. When I go into the bios settings I find that the date and time has returned to default. So I set the correct date and time, reboot and all is well until the next time.
After reading this forum I believe it is a CMOS Battery error.
Is it possible for me to replace this battery? If so where is it located on the mother board?
Thanks in Advance

Lenovo Thinkpad T510 Battery?

I recently (about 2 months ago) purchased a Lenovo Thinkpad T510 laptop. Ever since I got it, I have the brightness on 50%, and only use it to surf the internet. My battery life is 2:50 at the maximum.
I have a warrenty for the laptop, could I call in and get another battery for free?
It is quite inconvienent to have to charge and recharge at least twice every day. It makes portability almost impossible.
Solved!

Do you have discrete graphics? If so, it sounds about right for an untweaked system. There are a few tricks to battery life optimization with the NVidia GPU involving PowerMizer.

Enable PowerMizer, and use Max power save on battery.
Also put your CPU into the lowest speed in Power Manager's advanced mode (battery only; AC should be adaptive).

Lenovo y50 external battery

Is there a external battery that will work with the lenovo y50? seeing that it takes 6.75A and needs 20V output in order to run it with the battery adapter. I know most external battery have 20V output but there isn't one with 6.75A please post a link of any external battery that is compatible with the lenovo y50

Here's a link to a possible portable power bank, if thats what your referring to. http://www.amazon.ca/dp/B00BB5VQCE/ref=wl_it_dp_o_pd_nS_ttl?_encoding=UTF8&colid=42GBF7LOHUIF&coliid=ID0P1YN6JFW0C&psc=1 http://www.amazon.com/gp/product/B00BB5VQCE/ Both of those are the same product.

Lenovo Y50-70: Battery Caused Wifi Problem

Hello, When my charger for the laptop is plugged in, it seems to somehow limit my internet access. This phenomenon seems rather new, as I havent noticed it for months, unless I somehow ignored it. When it's in, browsers process slow, or internet connection ceases; in short, i get very frustrated with the wifi/internet when it's in. When it's out, wifi is MUCH better and flows smoothly; perfectly fine
Does anyone know what the heck can be causing this problem?

Thank you for replying!
So, when you talk about the circuit, do you mean the circuitry of my house, or the batter charger itself or the laptop itself? Should I request a new power coord and swap my old one with a new one, since my laptop still falls under warranty?
I spoke to my friend's family who are pretty smart with computers, and two said: "If the charger is emitting a high frequency noise, it will prevent the laptop from connecting. This is only possible however if the charger is charging (meaning using AC or DC electricity in any way."--"Laptop hardware is messed up, meaning the hardware is trying to charge your laptop and connect to the wifi through the same interrupt (same port)."Reference # 8005115756 I spoke with Lenovo support about it and customer support just forwarded the issue to experts; that's the reference number. Do you recommend that I just try to get a new charger and see if that fixes it? My laptop is pretty much unusuable in terms of browsing on the internet when it's plugged in. I could experiment to see what it does plugged in if i move into the room with the router, but I'm only a room away and it shouldnt make that much difference; besides, browsing works fine without the charger plugged in. I also haven't tried it plugged in at different locations yet, but I dont understand why it's having so much trouble when plugged in. Scrima99 wrote: "...when you talk about the circuit, do you mean the circuitry of my house, or the batter charger itself or the laptop itself?" Answer: The circuitry between your charger and the battery. See page 86 hardware maintenance manual or page 68 on how to remove the powerboard. Since your laptop is still under warrantee it is better to let Lenovo do the repair/troubleshooting themselves.

Lenovo z40-70

Basically, my laptop won't turn on anymore. Whether it's plugged in or not, with the battery in or out, nothing is happening. Within the past few months I've called Lenovo service twice regarding the laptop not charging. They've sent me a new adapter and new battery and it worked decently but it still charged super slow everytime. Recently I noticed that it took a while after I plugged it in for the laptop to actually recognize that it was plugged in to start charging. Unfortunately the battery life went to zero yesterday and I haven't been able to turn it on since. Any advice on how to fix this would be appreciated!
Solved!

Lenovo s850 inaccurate battery indicator

Good phone but the battery indicator is inaccurate. It's not very upsetting because the battery last for a few days but the indicator drops and raises chaotically. Most of the time it has a high value. In the last 1/2 hour of life the battery drops suddenly from 40% to 0% without even using the phone, and you are left with an unusable device. I received a couple of updates but the problem didn't disappeared. I bought the phone from Romanian operator Digi and has this versions: S850.ROW.V108, S850_ROW_S211_140923

Lenovo invented a self-contained battery (I can attach screen shots). I do not know why this great discovery have not done public.
Now seriously. I think this is more of a software problem. The statistics of the energy consumed is staggering. Screen 2 hours worked has used 2% and lenovo smart rotation process is used 58% . The company respecting their clients should already remove it.

Lenovo K 900 --Battery charge indicator always shows 100 %

A strange issue after firmware upgrade in lenovo K 900 , When I charged to 100 % , the phone always shows 100 % charge . It is not getting updated and after using for 6-7 hrs the phone gets switched off without any notice . Now I can charge again and this time the battery charge indicator shows correctly . but again the same issue is seen if the phone is charged to 100 % .

Let it die all the way down, to recalibrate the battery, and then fully recharge. See if that helps.
