Lenovo 11e E/Edge :: ThinkPad 15 Slow CPU While Charging Battery
Jan 24, 2013
With this laptop, the CPU usage rises significantly whenever the battery is charging. If I'm on running on battery power or it's fully charged, I don't have this problem. The CPU stays at 2-3% while browsing the internet, for example. But browsing the internet while the battery is charging will send the CPU up to 90-100%. It's not just browsing the internet, but any task, such as running Sony Vegas, using Skype, watching a movie, etc.
Again, this only happens while the battery is charging. Everything runs much, much slower. All power management settings are identical whether it be running on battery or charging with the AC adapter, so it's not that. I am also using the 65w power adapter that was supplied with the computer, and the adapter becomes very hot to the touch while charging.

I have a ThinkPad Edge 15. It had a charging problem from the day I purchased it. The people I bought it from sent it back to IBM/Lenovo who apparently tightened the area where the charging cord goes into the PC?
That did NOT fix the issue, so when I got my laptop back, I called LEnovo, they sent me a new battery (even though I told them the 'Power Manager' said the battery was in good condition) which did nothing. Then they sent me a new charging cord, again-nada. They sent me a box to send the laptop back to them. As I was figuring out how to put the laptop in the box, I looked over @ my PC, and lo and behold; the light that tells you if it is charging was shining!
Last night. I looked @ the charging icon; '15%, not charging'! Oops! Oh dear, not again! Went to power manager, everything is just fine. Checked all of my connections, same thing. I left the laptop plugged in. This morning as I look over @ the laptop & Guess WHAT! It was charging, the light was on! I turned it on...

I have a Thinkpad Edge E520 1143 AK7, working on windows 8, 32 Bit Pro.
From somewhere in the settings I had disabled charging option on "alwyas-on" USB port since I did not possess a smart phone.
Now, I have a smart phone and wanted to re-instate the facility. However, I am unable to find the option to enable the settings.
I enabled all the 3 options from BIOS and "refreshed" the machine to default state.
The USB port charges when the system is booted and stops charging when I shut down the PC.

I have a problem with my battery on a brand new E430. I've used it for 1 week w/o problems and now it simply doesn't want to charge the battery anymore. It is stuck on 48% and I have a message saying "plugged in, not charging".
EDIT: I run Win 8 (64 bit) - absolutely everything is up to date, including BIOS.

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.

So my battery from my Thinkpad e420s Laptop was broken and I ordered a new one and exchange it. But now when I go to the Power Manager it says Battery Error and I cant charge it. And when I take out the power plug it shuts down immediately. What can I do?

I bought 2 of these in oct 2011 for my twins going to college. My daughters has had no problems. The other one died in may 2012 and was repaired under warranty. It died again in November 2012. I was able to get it running by removing the battery and disconnecting the cmos battery and letting it sit for a while.
It happened again, and this time I can't revive it. I want to add that I think there was something wrong when we got it back from repair. The battery icon for the Lenovo power management did not work, but the windows one did. In hindsight I think this had something to do with nvram problem I have since heard so much about.

I have a problem with my Lenovo ThinkPad X300 computer. The battery charging stuck at 99% (remaining capacity about 69% and 300 cycles). The Power Manager displays, the battery is at 100% but "status" periodically changes - both Power Manager and Windows battery indicator - between "No activity" and "Charging".
Every time stuck at the same "Remaining capacity". As i noticed during battery user windows and the Power Manager displays different information about the remaining battery level and time.

I use a T440 with WIN8.1 pro machine but for whatever reason the external battery has stopped charging. As this laptop is only 3 months old Lenovo send me a brand new one but the outcome was the same, the charge symbol comes up on my screen when rebooting the machine and shortly after stops completely. I have now had my internal battery pack changed and again no improvement.

So this is about the only issue I have with Windows8 on my laptop, I've tried various audio drivers from OEM provided
to drivers directly from the Realtek site and I can't seem to remedy the issue....
Only during charging of my laptop or when the laptop is on battery does the jittery/distorted audio playback occur. Happens during Flash playback or local media playback using say VLC, sometimes the distortion can Freeze or lock up the system.....
I've tried Audio Drivers, Video and my BIOS is the latest. This playback issue did not occur under Windows7 when I had it installed....

Today my battery charging stopped working properly.
It does charge (or seems so) but it takes about 5 hours for each 1% percent.
The battery is the 9 cells one and the charger is 150 w.
The battery wage is at about 50% but it was charging as fast as always until today.
Things I have already tried:
- Charger is recognized by the BIOS as a 150 w charger.
- The laptop works without the battery (with the charger plugged in, obviously).
- Reflashed BIOS (version is A19).
- Recalibration of the battery.
All the warranty periods are over (both laptop and battery). Is it possible that I need a new charger even though the laptop is working without battery? Could I need a new battery?

I have an edge 530, i've had it about 2 weeks running windows 7 64.I have found that on default settings its fairly slow at waking up, i made one change which was to the wireless card, i unticked the allow my system to turn off wireless to save power (so it stays on). this seems to have made an instant difference and the laptop now wakes a lot faster.
The problem now is with having that option unticked, when my laptop does wake up the wireless is off when it wakes and will not turn back on, i have to manually turn it on. If i leave the power save option ticked for the wireless card it does auto connect when my laptop wakes.Seems a little odd as i thought unticking the option to allow my laptop to turn wireless off means it should just stay on but it seems to be having the opposite effect.all i wanted was for my laptop to wake faster and the wireless either stay on or auto connect after it wakes.

This is terrible, by using CPUz i can see that, whilst the laptop is charging, the clock speed drops down to 900mhz and fluctautes between that and 1400mhz, this is shocking, i can hardly watch youtube videos or even post this thread, the lag and slowness is unbearable. When running on battery power the CPU speed shoots up to 2500mhz and stays there,it never seems to go to its turbo speed either. Whilst charging, the laptop is unusabe, i cannot do anything on it.

ThinkPad Edge, Win 7 Sp1. For the last month I have had a problem with the control key always down. Programs react as if the control key were pressed. MS Word 7 gives an error message that the control key is down and asks if I want to go to Safe Mode. I have had the keyboard replaced with no change. The computer has been thoroughly checked, all drivers, patches, software upgrades have been made by my Tech, and the Bios has been flashed.
Last week, I found a post on Google for Win XP where the poster had the same problems. The fix was to ensure that the Sticky Keys were turned off in Ease of Access on the Control Panel. I went to Ease of Access and turned off all of the selections, and the fix seemed to work. However, yesterday the problem reoccurred. I don't know if it is a problem with the motherboard, hardware, or with Windows. It appears that this problem affects more than one version of Windows.

I just received my new E545 and booted it up. I've noticed the CPU is quite hot and so ran some software tests. It is showing the CPU temp around 92 degree C / 196 degrees F.
The chip is an AMD A10-5750M. I take it the heat isn't normal. Should I be sending this back to warranty?

I am experiencing issues with my touchpad on my Thinkpad Edge AMD with 4 GB Ram.
Sometimes the touchpad will work and sometimes it will not respond. When I restart the computer, it will work but not for long. I have the up-to-date drivers which came with the machine. I just received my machine 2 days ago.

I just purchased the E540. Running Win 7.1. I have 2 WD 3.0 Passport drives plugged into a USB 3.0 hub. The 3.0 hub has the correct cable for 3.0. They are not being recognized as 3.0 devices (I get a message). I updated the USB 3.0 driver on lenovo's site and BIOS is set to auto.recognize. I have also tried the 3.0 option in the BIOS but that didn't do anything. I also tried using the drives without the hub in one of the 3.0 USB slots but that didn't do anything either.
I have checked the forum but what I found was possibly purchasing a 3.0 cable (not necessary - my cable is 3.0 compliant) but that was for a Wn 8 system or updating 3.0 device driver (done). So much for plug and play.

This laptop shows "no operating system found" when I power up. I ran knoppix which works but I tried pressing F8 to get to the CMD prompt but it doesn't work, I can get into the BIOS, anything I can do in the bios to do either a system restore or run the recovery?

I just reinstalled windows 7 on my edge 13 (cause the system really slowed down), everything's working so far, expect the WLan Device. The network adapter (realtek RTL8168D/Familie-PCI-E-Gigabit-Ethernet-NIC) is properly detected, if i plug in a Lan cable I have got a connection.
I already tried this Lenovo Update tool, it installed some drivers and updates, but still no change. I already tried all Wifi drivers from lenovo homepage without success. Hitting the F9 Button didn't change a thing.

I've had several laptops but I am hating this one and is basically the Fn Keys and F# Key. I am pretty customed to use keys like F4(invoking word magic), F5 (update), Alt+F4 (closing windows)...
So, now I have to press Fn + F4 Keys, Fn + F5 Keys and Fn + Alt + F5 Keys....
So is there a way to continue pressing just F4 F5 and that's it?

Just a got a brand new Thinkpad 540-E. So far this CPU runs like a beast(with a new SSD installed). I have one minor issue though...
GOAL:: Make the F1-F12 keys function without having to press Fn first.
So I've tried the three tips I've come across online. Here is what happens:
1. BIOS(ThinkpadSetup): I only get the option to switch the Fn and Ctrl key. There are no option in my BIOS to do anything else with the keyboard/mouse settings.
2. Holding down the Fn key for 30 sec to 1 minute: Nothing happens. I even tried to do a three minute press and hold. I had a blast, but nothing came out of that neither.
3. Entering the keyboard settings in Win 7 manually: So I have no trouble entering the keyboard settings window, but mine looks extremely limited. In fact I see no options to do anything in there besides updating the driver.

I am planning to upgrade my RAM on my E420(1141CTO). It already has a 4 Gb on one slot. Couple of questions here.
1. What is the max RAM I can go upto on this E420 (Intel i3 2nd Gen) laptop.
2. As I have 4 GB on one slot can I put one 8Gb RAM (single module) on the other slot.
3. What brand of RAM I can use.
4. On this model can I fix another RAM myself easily or asking it the other way are the slots placed such that I can do it easily by merely oepning a couple of screws or do I have to tear everything apart.
5. Any other special considerations like about clock speed ?

I have recently purchased a Lenovo ThinkPad Edge E540, with Windows 7 installed. I'm trying to use the integrated camera with Skype, but I can record no picture. When I try to install the Integrated Camera Driver from Lenovo Support, [UR], the setup always fails with Engrish error messages.

I purchased a Edge E545 that came pre loaded with Win7 Pro 64. I created the Recovery disks for Win7 and used the Win 8 Disks to upgrade the OS. I have created a new NTFS partition on my hard drive and would like to install Win 7 to that partition. I have tried to load the recovery disks to install into that partition but I have not been successful; the boot disk won't even load. I downloaded the Win7 Pro 64 ISO to try and load it into that partition but the computer does not have the COA sticker under the battery like it's supposed to.
I have recovery disks that won't load at restart or cold boot and I have a perfectly good ISO that i don't have a COA to.
