Lenovo P/Y/Z Series :: Z510 - Slow Performance In Battery Mode

Mar 17, 2014

I have a lenovo z510 and i have one issue... when is plugged, it's very fast. when i unplug, everything is laggy. even when i scroll down on my facebook page, is very laggy. if i plug it in, it's very smooth and works perfect. I don't wanna mention if i wanna play assasins creed without being plugged in... is very laggy. I'm running windows 8.1 and all drivers are downloaded from lenovo website driver support... I've tried to change the profile.

On battery mode to run everything on maximum performance... but it doesn't work. same problem. I don't care if the battery runs out faster. i just want it to run fast when is on battery mode.

Lenovo P/Y/Z Series :: Z510 Slow Windows 8.1 Booting

Jul 12, 2014

I bought lenovo z510 recently and liked its performance. But from last few days am facing issue when windows 8.1 boots .ie., when i power on my laptop i see "lenovo log" for more than 15 minutes and sometimes windows doesnt start at all. I have to restart few times manually with power button to see the windows screen.
 
Initially i thought it is due to windows update, but even after I turned off update, am facing same issue. My laptop is hardly a month old and it is very frustrating to see this happening .

Lenovo P/Y/Z Series :: IdeaPad Z510 - Using Conservation Mode In Energy Management

May 26, 2014

I recently bought an ideapad z510. You cannot separate the battery in this device, but i really like to keep my battery safe from some dangers like overcharging and discharging.

Now, my question is this: using conservation mode in energy management, which is the software that you can download it from lenovo, can keep my battery imaginary off of charging or not? because the battery charge remains at 60% when you plugged in, and doesn't this mode work when the computer is off , but it still plugged in?

Lenovo P/Y/Z Series :: IdeaPad Z510 - How To Install Windows 8 In UEFI Mode

Jan 24, 2014

I have been struggling with installing w8 on my Ideapad z510 laptop in UEFI mode, but neither I could succeed it nor I could I find something that might work. I will clearly explain the case.

Point 1:
As I understood, to succeed w8 install in UEFI format, one needs to choose "UEFI First" mode from Boot Menu in BIOS. Then, the source of the boot needs to be specified to identify the rigid path to the documents to load so that new OS could be installed correctly.

Problem1:
It is possible to chose UEFI First from boot mode, but it's not possible to choose the USB path for UEFI booting in this case, which doesn't allow you to succeed a UEFI boot to your computer. You can't reach the DVD or USB, where the installation files are, and start installation process.

Point2:
Considering the first case, you need to choose Legacy Support mode to boot your computer and reach USB disk or DVD to install new OS on the computer. 
 
Problem2:
To succeed UEFI mode booting to the computer, you need to see 4 different partitions on your disk at point of disk selection, where you choose the disk you'll install your OS. However, when you select the Legacy Support mode from BIOS, the disk partition is limited to 2 in my case, which are:

Primary diskSystem reserved (350 MB)Hence, when I continue with the installation, the OS is installed on Legacy mode. After installation, when I go to BIOS to choose UEFI mode for boot mode, the laptop checks some connections from network and says

EFI network 0 for IPv4 failedEFI network 0 for IPv6 failed respectively.

PS: Please don't tell that "you can't install, because your computer doesn't support", because I received the computer from technical service and a version of W8 was installed on it in UEFI mode. However I deleted it to install W8 pro.

Lenovo P/Y/Z Series :: Z510 Battery Plugged In Charging But Remains On 0%

Feb 12, 2015

I installed windows 8.1 pro with WMC on my lenovo z510 laptop and installed energy management driver from laptop's drivers dvd. After I installed LEM (lenovo energy management) i started the gauge reset process for my laptop.

After some hours i saw nothing is happening so i made a mistake and cancelled gauge reset in the management software and after that when i restarted my laptop my battery icon says PLUGGED IN CHARGING but it just remians on 0% !!!!!

Problem solved by for example uninstall and reinstalling MICROSOFT ACPI. but notice that i reinstalled my windows 8.1 ! i changed in to windows 7 ! again changed it to windows 8.1 !!!

I updated the energy management software ! nothing happened !

Then try to restart to BIOS menu and from there restore BIOS defaults ! but i couldn't enter BIOS from any ways ! from pressing F1 ! from the way based on windows 8.1 and UEFI frimware settings (somthing like that) ! from none of them i could enter the BIOS!

So now my battery is still facing the problem !you know that it's not easy to unattatch and reattatch z510 battery that is internal ! so at last i must say that i've checked a lot of ways and now my battery is still having problem !

Dell :: Slow Performance On Battery XPS M1730

Jan 2, 2009

Does anyone have experience with very slow performance on battery power with the Dell XPS M1730?

The problem I am having is the following:

AC plugged in - everything works fine.
AC unplugged (on battery power) - the system is very slow. Watching basic video or a DVD is painfully slow, and video is choppy with skipped frames.

I have been working with Dell, and have updated all video drivers, Bios, tried different power settings (including high performance), and it has made no difference.

Lenovo P/Y/Z Series :: Slow Charging After Battery Reaches About 80 Percent Or So - Y510p

Oct 31, 2013

I was just wondering what the average time was for a totally dead y510p to charge while using it for some light browsing on the internet. It seems to charge really slow especially after it reaches about 80 percent or so. I was curious to see what other owners have had in terms of charge time. I seem to have narrowed it down to about 5 percent every 10 minutes while my cousins HP charges way faster. Not too upset about it but a bit curious. For example as I am typing this out it's been at 99% for the past 20 minutes or so, and HW monitor shows it charging really slowly but when its at like 50 percent it charges at a decent rate maybe about 10 mwh every 5 seconds or so.

Lenovo U/S Series :: S205 With Win 8.1 - Unable To Switch To Best Battery Heath Mode

Aug 3, 2014

Recently I installed Windows 8.1 instead of Win7 on my IdeaPad S205.  The problem is that the new Lenovo Energy Management tool doesn't let me swith the mode "Best Battery Heath". Everytime I click on it, it is automatically switched back on the "Maximum Battery Life" setting.

I also didn't find any tool where I can set my preferences (Best Battery Healt as standard). I have never had this problem on Windows 7.

Dell Inspiron 15 :: 5000 Series - Slow Performance / CPU Stuck At 0.75ghz

Aug 23, 2014

I've recently purchased an Inspiron 15 5000 series and have noticed that performance is unusually slow for the specs, especially since coming from an Asus G73JH that was about 4 years old.

I've noticed that in the Task Manager on Windows 8, that CPU usage never goes above 30% and although the CPU is listed as an i7-4510u @ 2.00ghz, the Speed on the Task Manager page generally sits at 0.75ghz and never goes above 0.79ghz (generally when it goes above 0.75ghz, it for a brief moment).

I've been Googling this problem for a little while now and the only person I've found with a successful solution to this problem was on a desktop and had to replace their CMOS battery. Considering I'm on a laptop, I'd imagine this would void my warranty somewhat ....

I've run the Dell Support program and all the tests pass. I've also installed all the drivers from the Dell site (including the BIOS update) and all my Windows Updates are up to date.

Lenovo W530 ThinkPad W Series :: Battery Lifespan Mode And Other Settings And Tools Missing?

Jun 30, 2011

On my old W520, it had a setting for making the battery last as long as possible.  E.g. it didnt charge it to 100%.In my W530, which has windows 8, I can find no such option.  In fact, all the Lenovo tools which came with the W520 dont seem to exist on the W530 (eiter because they dont have them for Windows 8, or they dont have them for the W530, dont know which).
 
The only lenovo tools I have are th "solution senter" from red icon in the task bar (which has a battery icon, but the only thing it does is say "batter is in good condition", there are no options or settings, and the thinkVantage button, which just brings up somehting like some shortcuts to control panel items - no Lenovo tools (just things like update drivers, warranty infomration, keyboard settings etc).
 
In the wiondows control panel itslef, are just: lenovo system healthlenovo update drivers 32bit (I never use this as I have 64 bit)Lenovo airbag protectionLenovo microphone muteIn control panel -> Power options is nothing Lenovo specific, and no lifespan mode, it only allows you to set when windows switches stuff off.
 
What happened to all the tools which came with windows 7, including the thing which told you how fast the processor was running, the thing to change your printer etc. with different locations?

Lenovo Y410p P/Y/Z Series :: Sleep Mode Turns On / Kills Battery / Overheats Laptop

Oct 5, 2014

I've read other forums on similar issues, but I can't seem to find one that matches mine exactly.
 
System: Y410p with
1tb hdd
24gb ssd
intel i7-4700
8gb ram
64x windows 8.1 (came installed)
 
Problem:
When I put the computer into sleep mode, it goes into sleep mode without issue. It has stayed in sleep mode for a maximum of 8 hours, but usually before it hits this long the system will turn on. It seems to run random processes and overclock the processor as the computer gets very hot. It will do this until the battery dies, or if plugged in, indefinitely.
 
While it is doing this I have opened the lid, pressed every key, including power, with no response. Once, and only once, upon pressing the space bar, it had actually come to the unlock screen as though it truly was in sleep (except it was still overheating and on). Otherwise my only option is hard shut down.
 
I've just gone around it for a while now by shutting down every time and not using sleep. But today I had put it in sleep, and placed it in my backpack where it nearly cooked itself to death.I have tried:

-I have checked the wake_armed, which currently display NONE
-I have checked last_wake
-I have fiddled with hybrid shutdown.

Lenovo X230 Series ThinkPad :: Battery Drains Quickly In Sleep Mode / Power Management Center Won't Run

Apr 15, 2009

I have my lenovo x230 laptop set to sleep when I close the lid. When I close the lid the "sleep" icon on the back of the screen lights up. But the batter will not last through the night on sleep mode. Within five hours or so, the battery is completely drained and I have to plug in and boot up the system. I've never seen such poor batter performance during sleep mode on any other laptop I've ever owned. 
 
Another thread in this forum blames the USB port that allows you to charge mobile phones/etc. during low-power states and recommends disabling the "always power on" option fo this USB port in the Bios settings. At least my laptop still will not make it through the night in sleep mode. 
 
At this point, it seems my ownly option is to use sleep mode only when the laptop is plugged in and hibernation mode when on batter power, which is disappointing. I've never had to worry about this in the past with other laptops. Perhaps/probably related is the fact that the lenovo ThinkVantage Power Manager (v. 7.16) hangs at the splash screen when I try to open it, so I've been trying to manage the power through the windows control panel power settings.

Lenovo Z510 P/Y/Z Series :: CPU Stuck At 0.77GHz

Mar 6, 2014

when i changed the option "intel virtual technology" to enabled in the bios configuration section, my laptop started at 3.2 ghz on battery, then i changed the power option from "high performance" to "power saving" mode, it was redused to 0.77, then i changed back to performance mode,it speeded up till max. it seamed problem was solved. 
 
i am not sure what intel virtual technology is doing or related to this issue, but it's worked for me.meh, after 3 restarts it's stuck at 0.77 again, i think we definetly need a bios update.After a quick search, i ve found that "intel virtual technology" doesn't related to this issue, and it' NOT THE SOLUTION.  problem still exists.
 
Also, just fyi, some other brands of devices faced this issue over the inernet and all solved by bios update or board replacement. This post was move to the top of the page to assist Lenovo with an escalation.

Lenovo Z510 P/Y/Z Series :: Does 8 GB SSD In IdeaPad Work

Apr 12, 2014

Recently I purchased a Lenovo Ideapad Z510, model name 20287, MO: YB03120328. According to the specification from my reseller (Dutch webshop [URL] and the Lenovo box it was shipped in, this laptop should have a 1000GB hard disk + 8 GB solid state memory (SSD) for caching. My problem is that I am not sure if the 8 GB SSD is working.

The SSD does not show as a drive in "My Computer", it does not show in Window's Disk Management utility (see Figure 1), Intel's Rapid Storage Technology does not show the possibility of using the SSD to accelerate performance (see Figure 2) and when running ExpressCache (with the command "eccmd.exe -info") the program tells me "HFS Volume is not mounted" and "ECCmd exited with error 0x10df (4319)".

All these clues lead me to believe that in fact no 8 GB SSD is installed, or if it is, that it is not working properly. Any additional ways of testing I could use to confirm it is or is not working?

Lenovo Z510 P/Y/Z Series :: Black Screen Loop

Oct 31, 2014

i have a new Lenovo IdeaPad Z510 (i5 Full HD with Nvidia Graphic Card). I bought it on 7th October 2014 and everything was fine under Windows 8.1 N Pro x64. But today when i started my notebook, i had a black screen for a few seconds and then it stuck in a reboot loop.
 
1. i press the power button
2. black screen for a few seconds
3. reboot and back to step 2.
 
i tried already the lenovo button, but this results in the same problem as above. I also tried to boot into bios by pressing every F1...F12 key and also Fn+F1...F12 key. And last but not least i tried to boot from Disk (Windows 7 Home Premium 32 and 64-bit, Windows 8 x64, Windows 8.1 N Pro x64 and Debian latest stable) but it didn't work, too.

Lenovo P/Y/Z Series :: Partitioning Hard Disk In Z510

I purchased Z510 recently with 1 TB hard disk. The problem is that it came with only 2 partitions :
 
a) Windows (C) - 891 GB
 
b) Drivers (D) - 25 GB
 
When asked with the support, I was told that if I make new partitions my warranty will void. and if anything bad happens on the software part I have to pay for that to fix it.
 
It is very difficult to work on a system with only above partitions.

Lenovo Z510 P/Y/Z Series :: How To Enable Booting From CD / DVD And USB Drives

Sep 16, 2012

I have a brand new z510 notebook, and I need to do a clean install of windows 8.1.  Problem is that I can't seem to boot from CD or USB.  I have entered the bios, and although the DVD rom drive works, and it shown correctly in BIOS, it does NOT allow me to add it to the boot list.  Also, there is an option called 'Boot From USB'  I enable that, and still the USB boot does not show up in the boot list.  The only thing I have in the boot list is the 'Windows Boot Manager' and it lists the name of my drive.  
 
I thought that maybe secure boot was the issue, but I tried disabling this, and is still doesn't let me do what I want. I just paid $800 for a top of the line laptop, and I can't even boot from a cdrom.  Every computer I have had since the 1980s have allowed me to do just that without trouble.

Lenovo P/Y/Z Series :: IdeaPad Z510 Stops Spontaneously?

At a certain moment the laptop stops and is completely off. The first time I immeditely checked if anything was hot, but the latop felt only just a little warmer than my hand.
 
I noticed that it occurs more often when it is on the AC adapter, but also when running on battery. I checked the temparature with 'speedfan' and the HD0 was about 39 degrees and the 4 cores where about 30 degrees.
 
I'm running windows 8.1 64bit

Lenovo P/Y/Z Series :: Z510 Random Shut Downs (hard) When Plugged In

Jun 8, 2014

My Z510 has been randomly shutting down when plugged in, but doesn't have this issue when running on battery. I contacted Lenovo and they sent my a new power supply but the issue continues. I called again and they instructed me to repair-install the Lenovo power manager and do a disk check. The issue still continues.

It used to happen when running something intensive like photoshop or a game and only if charging over 75%, but now it'll happen randomly. I can be sitting staring at the laptop with no programs running and it'll shut down.
