Re: Qosmio F50-126 - Freezes when on battery power

*hey everyone*
I bought my Qosmio F50-126 couple of months ago with 3 year international warranty. There is something about the notebook which really irritates me--- *THE FREEEZEE*.
I have noticed that when I am watching a video on any player and any format, the whole computer freeezess *for 1 or 3 seconds and resumes* by itself *But the interesting thing is that it ONLY happens when running on battery*. It runns like a dream when running on ac with battery being charged. *IT INCREDIBLY annoying*
When your into the movie and lights are off and your in ur comfly warm bed. The WHOLE computer freezes with the audio jittering. It only happens for 1 or 2 seconds but it occurance is *COMPLETLY RANDOM.* If the laptop is in the mood of watching the movie it only freezes 2 or 3 times but sometimes it just get on my nerve.
I disabled my kaspersky and other random process runing. Please help me!
*Just for the note: It only happens the freeze only happens when running on battery*. Oh- hope this help
I notices that my HDD light on the notebook doesnt blink that often when on battery and playing the video so its not the load time the reason... also...SAME RESULT WHEN I RUN ON HIGH PERFORMACE, BALANCED or power saver---actually powersaver is *_THE WORST.... BYE... PLESE HELP ME OR MY LIFE IS DOOM_*

hey-- i'm amazed with the quick reply.. thank you.. okay back to the notebook
Yes, i did install nvidia driver from there website, 9700M GTS driver. The lastest one there is. You are correct about the heating problem but i believe its with all the qosmio because after reading a thread on it about the GPU temperature, i think it normal which it shouldnt be. Like, when doing normal work, the gpu temps hovers around 60 C but when playing game,, max it reached was 105 C when ruinnin the game at max performancel. Forexample, farcry 2 when on ultra high runs smooth with the gpu temp around 101 but when everythikng low,, back to 'normal' temp 60. But the gpu temp isnt mine concern. My concern is the freeze. So you mentioned about Toshiba Display Driver and i will give it a test and see if makes any differnce. I hope it does but i'm afraid it might downgrade my graphic power frame rates but i will still give it a go and see if it makes any diference. Also, sometimes, my display driver stops working, the nvidia website downloaded driver.
And final answer to the second post,,, umm..i dont remember,, its just these few days its getting on my nerve and decided to post a thread on the internet.
hope this helppp... so..im goin to toshiba driver and download the display driver and see if that make a differnce.i hope it does..
bytheway... only thing i dont understand is why doesnt it freeze my runin on ac?

Qosmio F50-126 not supprted for Win 7 upgrade?

I am really getting angry about Toshiba and Windows 7 upgrading option.
I am really excited about upgrading my Qosmio F50 -126 to Windows 7 from Vista Home Premium.
But after doing a bit research on the issues involved in upgrading, I burst into anger.
I went to this link [http://aps2.toshiba-tro.de/kb0/TSB9902P50000R01.htm] to check whether my notebook is supported but because i paid good money for it i it SHOULD be supported.
But guess what.. IT ISN'T!!!
On top of that.. it says on the website that the notbook not mentioned will get 'limited support'!!!!
WHAT?? my 1999 dollar MACHINE WILL GET LIMITED SUPPORTED FOR WINDOWS SEVEN!.
What am i suppose to do.. buy another Toshiba or sue them to get the money and buy a new one???
Does this mean I CAN'T run windows seven will all the drivers runnin??? WHAT SHOULD I DARN DOOO??

hi abdusamed,
calm down - it takes some time to get all win7 drivers running, i am sure they will provide drivers for your cam etc...
but i think they are not tested yet.. and you wont get a driver that's improperly working, dont you?
and dont stress yourself with that "limited support"-thing...
this only means if a machine is deliverd with eg. vista there is support for vista only.
if you install antother os eg. win7 or linux they will give you "limited support" means if available they provide drivers and help.
just like running this forum (which is realy helpful to me and some others)
so just wait a little i am sure there will be a solution!
btw: you can investigate your hardware and get some reference drivers of the manufacturers..
but this will take a bit (lots) of time and some testing...
and i am not sure if there isnt any special hardware in it that causes the reference driver to work bad/not.
i wont do that ... but if you like....
btw: is there an official release date for win7-machines from toshiba?

This is often due to faulty battery. Make Genius reservation and take iPhone to Apple Store for free quick battery diagnostic testing.

MBP temperature when on battery power

Is it normal that my MBP runs so hot when on battery power that I cannot even use it on my lap? It seems like most of the heat is coming from the area below the top 3 rows of keys (if that makes sense) and not the battery itself.

Yes, the case is a heat-sink; Apple call them "notebooks" not "laptops" and warn against having them against your skin.
"Do not leave the bottom of your MacBook Pro in contact with your lap or any surface of your body for extended periods. Prolonged contact with your body could cause discomfort and potentially a burn"
MacBookPro_UsersGuide page 107
Actually, you don't want heat near the battery itself as that's not good for li-ion, that should feel relatively cool?

Laptop randomly switches off when on battery power.

When on battery power my HP DV3500EA laptop randomly switches off (this is only a recent problem). This is when there is still significant charge on the battery. This does not happen when on AC power. Once it has switched off, the laptop is able to be switched back on again and run normally until the next time it switches itself off. It doesn't shut down, it just turns off immediately as if the battery has run out. I have checked that it is not overheating - the CPU temp is generally between 40 and 50 degrees Celsius. I know this isn't a software problem because it does this on different operating systems (Windows Vista and Ubuntu Linux). I assume this means it must be a hardware problem, but I can't work out what it is or how to fix it.
Does anyone have any ideas?

Exact same problem with my Envy 13 running with windows 7... any solution besides bringing the laptop back to the store?

T42 Freezes Up when on Battery Power

I have a five year old T42 running on XP. When I'm on AC power there is no problem but when I switch to battery power the computer will boot but freezes up within a few minutes. When I re-boot the disc check comes on but freezes up before it completes. I have changed batteries but that does not help. Any suggestions?

I got my T61p last Friday. I'm having the same issues after applying all patches and driver updates. I can run fine on AC power, but as soon as I unplug the machine, the screen goes blank and I have to do a hard reboot. I have not been using Turbo Memory. For a few days it worked just fine, but then the problem started up again yesterday. I think it has something to do with the GPU.

T61p freezes randomly when on Battery Power

I recently got my new T61p and i'm absolutely loving it. However, randomly (and only when the laptop is not plugged in to AC power) the system will hang on certain tasks, usually web surfing since thats what I'm usually doing, and I'll have to do a hard reboot. Consequently, internet explorer and mozilla firefox tend to freeze sometimes when I'm on battery power. When I'm plugged into AC power everything runs perfectly.
According to this website http://www.utheguru.com/lenovo-ibm-t41-random-crash, this guy had similar problems with his t41. I have all the latest versions of power management and updated all drivers and patched vista. Any ideas on what to do? I don't want to uninstall power management b/c its so useful
edit: I use the 'Energy Star' profile for my power setting
another edit: Apparently it is to do with the Intel turbo memory. i'll try the solutions in this post and give u my progress: http://forum.thinkpads.com/viewtopic.php?t=51908

Q505-832 Freezes up when on battery power

My Q505-832 is running W7 home premium. When running on battery power the computer completely locks up. This happens after different amounts of time. It may lock up right after a boot. It may run for 15 minutes. All drivers are up to date with those on Toshiba's site. The computer runs fine while plugged in. The problem happens when the battery is fully charged. To be clear the computer doesn't die. The screen and everything stays on but I can't do anything. No mouse, no Alt-Tab, no Ctrl-Alt-Delete. All I can do is hold the power button down until it shuts off.

Hi padi,
Thats really strange issue...
Some more details about your notebook would be interesting. Are you running preinstalled Windows version or have you installed another OS?
Theoretically it could be a software/driver issue or hardware malfunction. At first I would reinstall Windows using Toshiba recovery disk.

Laptop freezes while on battery power.

I have Arch 64 bit install on a Thinkpad T510. While the laptop is plugged into power, it is rock solid and can run for days without a crash.
The laptop freezes up quite often when it is running on battery power. After anything from 15 minutes to an hour, it will probably freeze. I cannot switch to a tty, I just have to do a hard reset.

I'm not sure if tracker could be causing the problem, or if it is something else.
I have the discrete graphics card enabled - NVIDIA Corporation GT218 [NVS 3100M]

It might not necessarily be caused by loss of power, but maybe if the battery power dips? Or if the battery gets too hot and something overheats, then that could cause freezing. I'm only going by what I've found on google.
Anyway, I found another thread (not sure why I didn't see it before) that suggests that it might be caused by bluetooth (bluez specifically) https://bbs.archlinux.org/viewtopic.php?id=115814, but it seems like that was more of a locking up problem than freezing completely. I've remove bluez and disabled bluetooth for now anyway (unfortunately can't remove it completely because I'm on Gnome Shell) and I'll run on battery for a good while and see if things freeze again.
EDIT: also followed this - https://wiki.archlinux.org/index.php/HDAPS in case the problem was caused by the hard drive being moved about.

Ibook G4 freezes when using mains power

Hi There
I'm looking for a bit of help, hopefully someone might have had a similar problem.
When using mains power my ibook freezes with the screen visible but nothing moving including the mouse arrow. The only way to shut it down is to keep the power button pressed. The only way to restart it is to keep the power button pressed. This doesn't always work though. Sometimes the fan whirrs and sometimes there is a whirr and then a beep. Sometimes the start up chimes can be heard and nothing happens.
Generally after 2 to 3 attempts the computer launches and lasts for about 15 minutes before it freezes again.
Strangely there isn't a problem when I'm using the battery only to power the computer.
It has frozen when using Safari 3.04 and Indesign CS2
The computer has had pretty robust use as the main graphic design tool for the last 2 years
6 months ago I added more memory and bought a new battery
2 year old ibook G4 (Bought new Nov 2005)
OS 10.4.11
Processor 1.42 Ghz PowerPC G4
Memory 1.5 GB DDR SDRAM
13.75 GB available
Any Ideas?
All the best
Matthew

the cable mentioned runs inside the iBook though, not the power adapter cable.
adapter plugs into the connector, which is part of the "DC-in board", then there is a cable inside running to the logic board.
looks kind of like that:

it may not be what's causing the problem anyways, you may want to get it diagnosed by authorized service provider

HP Pavilion dv9920us will not bootup/shutdown when on battery power

When using the 2.6.27 kernel, my HP Pavilion will not boot up when using the battery power..... it won't shutdown either, it will just freeze mid-process unti I plug the AC adapter back in. During the boot up using the battery power, it freezes at the ACPI part.
This has happened on the 2.6.27-2-ARCH kernel, and all other versions of the 2.6.27 that I've built. (all rc versions from rc1 - rc7).
I wish I knew a way to fix this, I have a backup 2.6.26 kerenl on my GRUB list just in case there are no AC adapter outlets.... but it would be nice to fix this.

I have the NVIDIA GeForce 7150M / nForce 630M with AMD Turion 64 x2 TL-60 with 4GB RAM.... so it's pretty different than the dv9000.
My AC adapter is different too.

MBP (13-inch, early 2011) goes into hibernation instead of safe sleep upon closing the lid (only when using battery power)

MBP details
13-inch MacBook Pro, early 2011 (model identifier: MacBookPro8,1)
Running Yosemite, OS X 10.10.1 (however, problem started while using Mavericks)
2.5 GHz Intel Core i5
4 GB memory
Symptoms
* the MBP goes into hibernation instead of sleep upon closing the lid on battery power (i.e., when AC adapter is NOT connected)
-- problem does not occur when AC adapter is connected
* putting the computer to sleep by other means does not induce the problem; these other means include:
-- [i] option+command+Power,
-- [ii] Apple Icon --> Sleep,
-- [iii] in Terminal: pmset sleepnow
* the battery is NOT getting drained at all; if I close the lid on 87%, the battery is still at about 87% when I get the MBP back up and running
To be as clear as possible:
(1) MBP is on and in use (power source: battery); battery is at X%
(2) the lid is then closed
(3) the battery indicator light glows bright for about 10 seconds, then shuts off, and with it so does the MBP (all fans and sounds cease)
(4) opening the lid and pressing any key on the keyboard does nothing (the computer is not sleeping)
(5) to turn the MBP back on, I must hit the power button once; this brings up and the gray screen and loading bar indicative of returning from hibernation
(6) log in; battery is still at X%
Attempted Solutions / Fixes
There are Apple Discussions addressing similar MBP issues, many of which at least have work-arounds, if not full-blown solutions. However, I have tried many of the proposed work-arounds and solutions; nothing has solved my problem. Such attempted solutions include:
* made sure EFI/SMC firmware was up to date
* updated all software
* logged in as a different user
* booted in Safe Mode
* reset the PRAM
* repaired disk permissions using Disk Utility
* repaired additional disk permissions in recovery mode (a la this chron.com advice)
* ran the Apple Hardware Test multiple times (short test while plugged in, short test on battery, extended test while plugged in, extended test on battery)
* booted from an external known-good OS on USB drive
* reseated the RAM
* used MemTest to test the RAM's health (it was good)
* tested my battery's health with the app Battery Health (it is healthy!)
* booted my computer with one stick of the MBP's original RAM at a time (figured "why not?")
* booted my computer using other sticks of RAM
* checked my power management settings using PMSET in the terminal (e.g., pmset -g); tried various hibernation modes (e.g., sudo pmset -a hibernationmode X, where X=0,1,3, etc)
* searched/grepped through my power management logs and Console messages to look for googleable items (e.g., pmset -g log | grep WORD, where WORD=failure, sleep, etc); still have not found help online
* brought the MBP to a Mac Genius
-- he ran some further tests, but found nothing;
-- he re-installed my OS as a hopeful-hail-mary-just-maybe-last-ditch effort; the problem persisted!
-- we both agreed that we had ruled out a software cause
-- he offered me to leave my MBP to get fixed for a flat fee of $300.00 (which after a couple weeks of trying to figure this out is starting to sound more and more reasonable)
Given that it is likely not a software issue, what hardware might it be? By booting from an OS on an external drive, I think I've ruled out a bad hard drive or hard drive cable. Also, given that inducing sleep in any way other than closing the MBP's lid does not cause the problem, it seems there might be a wire (or something) in the hinge section of the MBP that gets moved when the lid is closed possibly causing some kind of short circuit...or something.
If someone with more experience interpreting Console messages, for example, can help, I'd be happy to provide some logs, or any additional information.
Thank you for your time and consideration.

Ok, this is a crazy-simple, quasi-embarrassing fix, but I'll post it anyway just in case anyone is having a similar problem (for example, this guy: Changes to pmset being ignored).
Some time around late last August / early September (2014) this issue began happening for me (specifically, issue = closing lid while on battery power induces hibernation / shut down instead of sleep --- independent of hibernation mode). Maybe it was when I upgraded to Yosemite (not sure what the exact date of that was). As detailed in my original post, I frantically tried everything I could think of... At that time, however, I had quite a few presentations and posters to create and present at meetings and conferences, so I held off fixing it for a couple of months and returned to it this past week, where I tried a few more things listed above, but again to no avail...
This morning, I simply tried fudging around with all my power management settings again (via pmset in Terminal). The simplicity of the fix surprised me. But now that I understand it, I know it is likely the same fix for other threads I've read, such as the one above:
(TLDR in bold)
(1) Take note of your power management settings (Terminal: pmset -g custom)
(2) Is the "standby" flag set to 0? If so, set it to 1. Wa-la! Done.
This fix is crazy and embarrassing b/c I was so close to it for so long. I tried changing my hibernation modes multiple times (sudo pmset -a hibernatemode X, where X=0,1,3,25,etc). I read about manipulating other PMSET settings that helped other people with newer MBPs, like "autopoweroff" and "autopoweroffdelay" --- settings that I do not have on the MBP early 2011 (check your settings: pmset -g cap). And most amazingly of all, I even messed with the "standbydelay" setting, trying to make it so long that my computer should never go into hibernation... Yet, from what I can tell by looking over my notes, I never simply set "standby" from 0 to 1.
There are interesting questions that arise due to this fix. For example, why did this problem persist on clean installs of OS Yosemite? Is "standby" being set to 0 the Yosemite default? I'm not sure. If it is, then Kappy was right: this was normal behavior... It just wasn't always the normal behavior...at least not for my MBP. Normal behavior (hibernatemode 3) used to be (and now is again) that the MBP goes into safe sleep, and then only after an allotted amount of time will it go into full-blown hibernation.
NOTE: the "standby" and "standbydelay" PMSET settings are not available in some earlier MBP models (e.g., my brother has a 2010 and does not have these settings); so if you're having a similar problem with an earlier model, this fix might not be of any help to you.

T61 Buzz coming from upper left hand side when on battery power.

I have had 2 or 3 T61's exhibt the same problem. When the laptop is on battery power, I hear a very annoying buzzing noise coming from the upper left hand corner of the laptop. It seems to originate right next to the exhaust vent next to the speaker. Does anyone know what can be causing this? I have the most recent BIOS update as well. The second the unit is plugged back into A/C power, the sound disappeares.
Its driving me crazy!!

This is a hardware problem or glitch with the older Core 2 Duo processor, it was industry wide problem, there is no real fixes for it, other than to turn power saving features off and put the processor at max performance on battery.

Randomly Shutting Off When On Battery Power

So, I recently had my logic board replaced because my built-in audio out port wasn't working. I had this done more than a week ago, but just 2 days ago I was using it without being plugged in for over an hour (the battery indicator said I had about 50 minutes left of power) and then suddenly, it just shuts down. I hit the power key, and hear the startup "ding", and then hear it shut down seconds later. I plug it in, and start it up, and it works fine. Then last night I was using it on battery power again, and when the battery said 57 minutes left, it just shut down.
Could this be from my new logic board?

Hi E,
Unlikely, but possible. More likely the batt is dying. Time indicators have never been known for their accuracy, and a batt starting to die increases that problem. Check the condition of the batt (Apple Menu:About This Mac:More Info:Power) and post back.

Screen flicker when running battery power?

Hi MSI Fans!
Do you guys have the problem when your screen flickers very badly when running battery (unplugged)\
If mods know how to solve it, it is appreciated if you post here. Thanks a lot!

try set gpu to max performance from control panel power profiles
note make sure to edit the right power profile which is used when the notebook is running on battery only

KK I will do that the next time I will use the laptop but really, the battery life is bad and I have to use even more electricity to power the laptop to avoid flicker?
Hmmm it flashed right after a unplugged the computer but for some reason it isn't flickering, maybe when the battery gets low then it flickers? Since last flicker was just about 2 days ago.
Any advice?
