[somewhat solved] Charging thresholds with tp_smapi issue

I installed the latest Arch linux on my Thinkpad Edge e420 without any issues (so Ubuntu did teach me something the last ~5 years) and was following the tp_smapi wiki how-to on changing the battery charging thresholds when I found that when I set either one (either start or stop), it would change the other to being one less or one more:
[root@arch josh]# echo 80 > /sys/devices/platform/smapi/BAT0/stop_charge_thresh
[root@arch josh]# cat /sys/devices/platform/smapi/BAT0/stop_charge_thresh
80
[root@arch josh]# cat /sys/devices/platform/smapi/BAT0/start_charge_thresh
81
[root@arch josh]# echo 40 > /sys/devices/platform/smapi/BAT0/start_charge_thresh
[root@arch josh]# cat /sys/devices/platform/smapi/BAT0/start_charge_thresh
40
[root@arch josh]# cat /sys/devices/platform/smapi/BAT0/stop_charge_thresh
39
And this happens for whatever number I chose for `start_charge_thresh` or `stop_charge_thresh`. Running `lsmod`, I see that `tp_smapi` and `thinkpad_ec` are both installed and running,
josh@arch~ # lsmod
tp_smapi 20660 0
thinkpad_ec 4253 1 tp_smapi
Any suggestions? Or needed extra information?

Despite having the start/stop_charging_threshold set as 40/39 as in the above example, my battery charges to 80% and then stops (I've done this three separate times, leaving it plugged in with enough time to charge it 100%, and each time it stopped at 80). Another one of those Linux quirks, I guess.

How can I solve my problems with freezing issues with Lion?

I have a MacBook Pro from may 2010 and recently purchased Lion from the App Store and installed it as suggested. Since then my mouse goes crazy and gets hung up and pages take a lot to load and freezing becomes a continuous thing. Freezing even occurs once a page is open and I want to move downwards or upwards.

Do you have any data on the machine which needs to be saved? If not, I'd just erase the HD and install from the disc which came with your Mac.
If you do have data and/or don't want to start from scratch, and you have the backup I mentioned in my first post, either restore from Time Machine, or clone back from the clone (depending on which backup you have on an external HD).

T520: Slice battery charging thresholds stuck

I bought a T520 (4240) a few months ago and, like most people around here had the same issues with pulsing fans and, on applying BIOS 1.28, CPU throttling issues. I'm not sure if the latter one is fixed properly yet, but I also have a problem with the battery charging thresholds that has me stumped.
I have the 55++ and 27++ 9-cell main and "slice" batteries. For a while I let them charge up to 100% whenever connected to AC, but then I read that a 100% charge level is not recommended for day-to-day operation.
I use Fedora 15 Linux 99.9% of the time on my T520. I wanted to set the battery charge thresholds to avoid the 100% charge level, but the "tp_smapi" Linux driver doesn't work for the T520 (yet). I read somewhere that if I were to set the charge thresholds with the Lenovo Power Manager in Windows 7, that they would work in Linux as long as the laptop was not completely powered down when switching from Windows to Linux (i.e., use a warm boot). Well, it worked. In fact it worked really well: I could even power down and remove the batteries and something, somewhere would still remember that I wanted to start charging the slice battery when it dropped below 35% and stop charging it at 80%, even when running Fedora 15.
Having used the machine for a few weeks, I found that I used it on battery power a lot and liked to "top up" the batteries over night. The 35/80 thresholds didn't really suit my working pattern. So, back in the Power Manageer in Windows, I changed the battery thresholds from 35/80 to 50/88 for both batteries (55++ and 27++). On booting back to Linux, I noted that the main battery would respect the new levels, but he slice battery was still stuck on 35/80. Back in Windows, I tried changing the levels in different ways, but the slice battery refused to charge to more than 80%, even under Windows, no matter what I did. It seems that my first change from the default (is it 96/100?) to 35/80 has gotten stuck somewhere and I cannot change it again.
I even notice in the Power Manager that the slice battery constantly toggles between charging and not charging when under AC power if I set the threshold to 85/90. Because the 80% level where the battery is stuck is lower than 85% (my new "start" threshold), charging kicks in, but it immediately stops again, as it won't go over 80%, then, of course, it starts again and stops again, and so on.
How do I fully reset the charge thresholds on the slice battery so I can exceed 80% charge?

I had kind of given up on this, but thank you KooMaster for your confirmation that I am not alone with this issue. I don't think this is a problem with the Lenovo or Windows software, as this happens to me when running Linux without either of those. My guess is that the problem is in the embedded controller (EC) firmware. It is responsible for charging the batteries and enforcing the charging thresholds (that's why they still work even when the machine is turned off).
It probably makes sense to charge each battery to 80% first, as it likely only takes half of the overall charge time to get to that level (the last 20% taking as long again). That way, we get both batteries to a useful charge level as fast as possible. However, based on your observations, it seems that someone in Lenovo forgot to tell the EC to check that the main battery has reached its upper charge threshold, not that it has reached 100%, before topping the slice battery up to its upper charging threshold.
Can someone in Lenovo please comment on this issue, as I raised it over seven months ago now and I haven't heard a single word from any of you about it? "KooMaster" has confirmed the problem on a different model with different batteries, so it seems highly likely that a quick check of the (shared?) EC firmware code and a patch will resolve this quite quickly.
(I updated my BIOS and EC firmware today and it made no difference to my problem.)

Can no longer change charging thresholds on t510 with latest update

I just updated to the latest version of lenovo settings dependency package - 1.2.1.5. Afterwards, I was unable to set my charging thresholds via the registry as per the existing thread. The values in the registry stay, but restarting the computer does not make the battery not charge past the threshold.
This is what Lenovo Settings shows:
And this is what I changed the Registry to:

(SOLVED)Toshiba P850 UEFI and issues with bootloaders

So I've been using Arch for over a year and a half and have installed it on 10+ systems. I got a new laptop in January 2013 which has a UEFI motherboard (I hate Intel) And ive tried installing Arch from pure memory and also from the beginners guide, the first day I got the laptop I installed Arch in 15 minutes with NO issues, now all of a sudden when I boot into UEFI (For some reason legacy support which is called "CSM" Does not seem to work with Arch, so I must use UEFI, if you know a way around this let me know) on the live disk, install goes successful, but when I try and install GRUB (Not grub-legacy) it says "UEFI Commands are not supported on this device" I read the article in the wiki about starting the kernel module, and I did that, install went successful with GRUB and I was able to make my grub file install to /boot/efi/EFI/grub.cfg. When I try and boot up it takes me to a grub screen for about 2 seconds, then reboots, then shows grub for 2 seconds, then reboots, etc..... And the grub menu that pops up ONLY says "grub" twice, it doesn't display any information as to what its going to load, so it seems like it failed. I DID change the root directory which is sda4, and I still get this issue.
My partitions are:
sda1 /boot 300MB
sda2 /boot/efi 700MB
sda3 SWAP 2048MB
sda4 / (the remaining amount of my 1TB HDD)
Does anyone have any tips? I really need to get this working.
EDIT: Also, I have tried SysLinux as well, that didn't work either. I don't care what bootloader I use as long as it can boot Arch! Ive currently got Debian installed and for some reason that's failing as well, but that disables my screen due to a kernel issue, I see the module fail to load in SystemD with Debian and it goes out, so I need Arch. Debian isn't that great anyways IMHO
SOLVED: Just installed via CSM instead. Took me some work arounds but i finally got it installed.

grub-install --target=x86_64-efi --efi-directory=/boot/efi/ --bootloader-id=grub --recheck --debug
It told me to do that HERE
First, mount the ESP at your preferred mountpoint (usually /boot/efi, hereafter referred to as $esp). On a first install, you will need to mkdir /boot/efi, if that's where you want to mount it.
Now, install the GRUB UEFI application to $esp/EFI/grub and its modules to /boot/grub/x86_64-efi:
# grub-install --target=x86_64-efi --efi-directory=$esp --bootloader-id=grub --recheck --debug
The way I understand it is that I still needed /boot to be the MBR boot partition, then /boot/efi as the UEFI partition so I can build compatibility with my legacy support later on, right now that's an even bigger pain as it doesn't fully work (After I get it running with UEFI I can tinker with it, if I cant get it running then ill have to wait for a BIOS update).
Also, ive tried the Alternative method listed below that and it still didn't load GRUB like it should have, same original error
Also, right now im trying to install with just using these partitions:
mkfs.fat -F32 /dev/sda1 #EFI BOOT 700MB
mkswap /dev/sda2 #SWAP 2048MB
mkfs.ext4 /dev/sda3 # / Remaining amount of my 1TB HDD
Right now im going to wipe my HDD and then try and install using GummiBoot, I had it all correct but my partitions were not GPT so it didn't work (Which is most likely why GRUB failed, I don't know too much about the differences but from what I know that's what did it) Now when I try to erase and re-partition using a GPT tool it gives me an error saying its not possible to partition /dev/sda or something along the likes of that, im going to see if I can try gparted live later tonight or tomorrow instead of the one they use in the beginners guide.
Im honestly confused as to how I got it running earlier this year when I set it up lmfao. I know I used cfdisk to partition and was still using UEFI.

My late 2009 iMac 27 inch hard drive just failed and is being replaced. It did not qualify for call back but I am wondering if there is others with similar issue

As I stated my late 2009 iMac 27 inch hard drive failed and is being replaced.. I am being charged as machine does not qualify for the call back program..call backs are on 2011 machines.. However i am in shock that my segate internal iMac hard drive failed in less than two years.. are there others with similar issue? Also when I get machine back will new hard drive be stable .. How do I make sure my working environment is reliable.. I have all my data and work backed up and will be able to rebuild my system but I really do not want to have to go through this down the line again.

Just to update everyone and maybe help people down the road .... It has been a week of **** .... I may have finally solved a problem that I have seen a ton of people in all different types of discussions around the world having trouble with ...... I am going to upload some pictures of what I was getting in the beginning and it came out of no where .... I had the random pixel problem with my display and to make a long story short I came across an article two days ago regarding internal temperatures and fan speed ...... I kept reading about apples approach which is not the point ..... More importantly I dug deeper into temperature control and fan settings .... I discovered all kinds of software and there is only one in my eyes that can help anyone dealing with this display problem .... I will be honest, I do not have the money right now for anything extra and am barely getting by and that is why I kept at it ... I figured keep trying different things because a repair is out of the question ... http://www.crystalidea.com/macs-fan-control - This program has solved my problem - I get to adjust three internal temperatures inside my Imac and slowly but surely as the temperatures remained constant the display is fine .... Like new again .... I cant believe it ..... Turns out the ATI Radeon HD 4850 512 MB graphics card gets very hot causing it to not do what it is supposed to ..... Anyone that has any questions do not hesitate to contact me ...... I am going to upload some pics ....

T61p new battery custom charging thresholds unfunctional

Hi! I bought a new genuine lenovo battery for my T61p 8891 CTO running Win7 64bit. When I use this new battery, the custom values inside the battery maintenance dialogue are complely ignored, and the system always charges the battery to 100%, even if I plug it in at 98%. With the old battery, I worked with 70%-90% thresholds which worked perfectly fine! But not with the brand new Lenovo spare part. I updated to Power Manager 6.36 and installed the latest PM Drivers from Lenovo Driver Matrix, but nothing works. I already tried to reset the battery, but that error won't let the discharge cycle happen, because as soon as the battery reaches 99%, it is reloaded. Any ideas?
Solved!
Go to Solution.

The charge thresholds seem to be specific for the battery you're using when you set them, if you plug in a different battery it will ignore them. I'd recommend putting the old battery back in, turning off the custom settings, close power manager then shut down and switch batteries and restart. You should now ab able to set a charge threshold for the new battery... assuming it's working properly.
If you want to do a deep cycle recharge to condition the battery, run it as close to 0% as you can get, then boot to bios and let the computer sit until it shuts off from low battery, you'll then be as close to 0% as possible. Now plug in AC power (without starting the comptuer) and let it charge for 8-10 hours.
When finished not only check that the charge threshold work, but also your max capacity to make sure it's close to 100% of design limit. I've seen brand new batteries in the 80% range before, but most are 98-102%. If a brand new battery is below 95% or so I'd see about getting it replaced under warranty.
Good Luck

Battery charging and power adaptor issues

I'm having slight issues with both my power adaptor and the battery itself.
First I think I have cord issues as the light status can change from dim green to red or bright green if I move the cord around.
Second, my MBP is having trouble recognising if power is going to the battery or if it's charging etc. It can recognise if there's no adaptor connected at all, but if there's an adaptor connected, it has trouble seeing if there's power coming from the adaptor even if the light is on. I.e. it can stay at 100% and supply comes from the power adaptor and then suddenly drop to 80% power and start charging agan. One issue that happened earlier today was the adaptor was connected, and the battery indicator was at 100% with supply from the adaptor. Suddenly the MBP shutdown, and when I rebooted it was at 17% (I've tried repeating that in case of a dodgy battery but I couldn't)

If that doesn't help, the problem could be the adapter, the battery, or the I/O board (or a couple of less likely things). If you can borrow another adapter and/or battery, try them to see where the problem is. Or, if you're near an Apple Store, take it in and they'll diagnose it for you (for free, but they will charge for repairs if you need them and don't have AppleCare).

Hi can anyone help with this issue regarding my wireless magic mouse? When im on google chrome and scrolling down the page i always have youtube running in the background but the audio cuts/spits/pops can anyone help me with this?

The figures you mention only make sense on your intranet. Are you still using the same wireless router. The verizon one is somewhat limited as far as max wireless-n performace. For one thing it only has a 2.4 radio. I like many people who wanted wireless-n performance before they even added a wireless-n gigabit router, have my own handling my wireless-n network.

A suggestion for those with battery issues:

When I first got my iPhone, I had the same battery issues many people here are talking about, in fact I posted about it myself. Its fixed. Very fixed, and Im very happy with my battery life. Here is what I did.
First, do not charge it using your USB connection. At least not always. Why? I dont know. I did the first few days, and couldnt get a full charge even tho system wasnt going to sleep. I started using the wall charger, and got longer battery life, but still not great. One night, I forwarded the phone to my home phone in case I got a call, and shut the phone down completely, and put it on charge. In the morning, I woke up to a 100% charged, fully glowing battery icon. The battery lasted all day with no issues. Every night after that, I just charged it on the wall charger, but did NOT shut it down to see what happened. I am still waking up every morning to a 100% fully charged battery. The battery life seems to get better daily now.
Today, I ran wifi for about 5 hours because I forgot to shut it off. This was after going to the pool and listening to the iPod on the phone for about 2 hours. And using the phone normally throughout the day, checking mail, sms, etc. Really a full day of work, and my battery is still over 50% full. I purposely didnt connect it to anything during the day for a recharge, not the USB or wall charger.
Good luck, hope this helps. Id be interested to know if it does.

Here's my non-scientific experiment.
After surprising battery drain for the first 10 days or so with not much usage, I completely drained the battery yesterday until the phone shut off.
I plugged into AC charge and was worried when it didn't seem to even begin charging.
I plugged into USB, assuming it needed to charge enough to at least complete a sync.
I left it on USB until about 5-10% charge, then switched it to AC. At about 50% I needed to use it, so I did but sparingly, and put it back on charge, all the while keeping Mail on manual and WiFi off.
I took it off once more to get it home from the office, then plugged into AC.
I left that charging overnight.
I never actually got the "glow", but did get the plug icon showing full charge in the status bar.
After about 2 1/2 hours this morning, the status has not moved off of 100% (but with little usage as before).
This is definitely an improvement already though. Hope this helps.

Will Apple help me with this issue?

Dear Sir or Madam，
I am a student in China, I really need your help, my iphone now problems bothers me! HELP ME PLEASE!!!
As I bought my iPhone 4s(16GB,White) in the USA from Sprint, full price with tax, unlocked ,it was excepted to be a global phone. But now I come across with some problems in China using local carrier.Now I am in China, not the normal use of the phone, I rely on odd jobs to earn, very not easy, English is not my mother tongue, maybe there are many grammatical mistakes, I hope you'll forgive me! Mobile phone can not be used normally I am very sad, I can not contact the parents and friends, can not let them worry about me, I've tried all means, including the upgrade to 6.1, but still can not solve the problem, I think maybe I am in China, so can not be used normally, at this moment I am very anxious, because of the time difference, it is later I can send mail, you can see it, please help me, a Chinese student's request!
I tried all the possible solutions from the Internet, and the Official solution offered by Apple (http://support.apple.com/kb/TS4459), but it doesn't seem to work.
Will Apple help me with this issue? Please do.THANK YOU VERY MUCH!!!

We are not Apple, and Apple does not unlock phones. Sprint will unlock phones, but you have to qualify. One of the qualifications is to have been a customer in good standing for a period of time. You can check their website for what that is. After that, they can unlock the GSM side of the phone for International use, that is it. If you are on a CDMA carrier, then it cannot be unlocked. Are you trying to use a local SIM card in China?
Your only option is to contact Sprint to see if you qualify for an unlock. Only they can unlock it. Sprint is one of the poorest choices to take to another country.

Will the 10W Apple Charger work with my iPad Mini

Hello Everyone
I got a ipad mini for christmas and because the lightening cable and 5W charger don't reach because i have only got one socket accesible in my living room i was thinking about buying the 10W Charger from Western Computers in Cheltnam, Gloucestershire And I Have a few questions about it because it does not tell me on the website which devices it is compatible with my following questions are
Will It work with my ipad mini?
Will it charge my iPad Mini Quicker?
Will it be compatible with the lightening cable my ipad comes with or will i have to get a adapter of some sort?
Please can someone answer my questions and reply because i do not want to wast my £25.00

The 10W charger will work on all of Apple's iDevices. It will charge your Mini faster.
The quickest way (and really the only way) to charge your iPad is with the included 10W or 12W USB Power Adapter. iPad will also charge, although more slowly, when attached to a computer with a high-power USB port (many recent Mac computers) or with an iPhone Power Adapter (5W). When attached to a computer via a standard USB port (2.5W, most PCs or older Mac computers) iPad will charge very slowly (but iPad indicates not charging). Make sure your computer is on while charging iPad via USB. If iPad is connected to a computer that’s turned off or is in sleep or standby mode, the iPad battery will continue to drain.
Apple recommends that once a month you let the iPad fully discharge & then recharge to 100%.
How to Calibrate Your Mac, iPhone, or iPad Battery
http://www.macblend.com/how-to-calibrate-your-mac-iphone-or-ipad-battery/
At this link http://www.tomshardware.com/reviews/galaxy-tab-android-tablet,3014-11.html , tests show that the iPad 2 battery (25 watt-hours) will charge to 90% in 3 hours 1 minute. It will charge to 100% in 4 hours 2 minutes. The new iPad has a larger capacity battery (42 watt-hours), so using the 10W charger will obviously take longer. If you are using your iPad while charging, it will take even longer. It's best to turn your new iPad OFF and charge over night.
