Portege Z830-10F and battery calibration

I have a problem with Portege Z830-10F battey.
With no alerts, shut down, and when begin charge the level begin at 51%.
In 1 hour the charge is full.
There is a metod to calibrate the battery ?
Best regards.
Nicola

> There is a method to calibrate the battery?
The battery can be calibrated by discharging the battery until it would be fully empty and then charging until the battery indicator would switch to green (in some cases blue). This indicates that the battery has been recharged.
This whole procedure should be repeated several times in the row.
But note: even if you would calibrate the battery, it might be possible that the battery would not provide the same performance because of the battery age.
Sooner or later every battery would start to lose the charging performance and in such case its just a matter of time when the battery should be replaced.

Portege Z830-10F - WLAN stops working when USB3.0 port is in use

Hi,
The wireless connection on my Portege Z830-10F stops working whenever I plug a device into the USB 3 port. The wireless connection comes back up as soon as I remove the device.
The problem happens with any device I plug in. I've tested with external usb disks (both usb 2 and usb 3), usb sticks, a wireless mouse receiver, and a printer/scanner.
This problem only happens when something is attached to the USB 3 port. The USB 2 ports located at the back do not have the problem.
The USB 3 port itself is working fine.
Currently running windows 8 pro:
* Wireless lan adapter: Qualcomm Atheros AR9200WB-1NG (driver version 10.0.0.75)
* USB 3 port: Renesas USB 3.0 eXtensible Host Controller - 0096 (driver version 6.2.9200.16420)
As far as I can see Ive got the latest drivers installed on both the wireless lan adapter and the usb 3 host controller.
The problem occurs both under windows 7 and windows 8 pro. I used the Toshiba Upgrade Assistant to upgrade from windows 7 to windows 8.
This problem has been present ever since i first got this laptop. Ive already done a reinstall / recovery back to original setup with windows 7 but this doesnt solve the problem.
Does anyone else have this problem?
Is there a way to solve this problem?
Thanks!

Hi
To be honest this is the first time I read about such issue.
I have no idea how an device attached to USB 3.0 port could affect the Wlan functionality.
I guess its hardware fault and this should be checked by an Toshiba authorized service provider.

Alternative power chargers for Portege Z830

Hello,
I 've got PORTEGE Z830-11M and with original 45W, 19V *PA3822U-1ACA* AC Adapter.
Can I use for charging it also more powerful 75W, 19V original TOSHIBA *PA3468E-1AC3* adapter, which I have on the other location?
Is it good for z830 or not and why? The only difference between them is power, I suppose more is better (less heat for charger) or not?
Thank you for answers.
Tomo

Brixx, thank you for answer, but I still don't know, why TOSHIBA service says that I should use exactly PA3822U-1ACA AC Adapter.
There are many TOSHIBA types of chargers with DC 19V output connector 5.5/2.5 mm and also other brands like ASUS which with their electrical specifications fit z830 laptop.
I would say, all chargers with at least 45 W and constant 19V DC voltage and of course 5.5/2.5 mm connector would be OK. But it seems they are not. I'm interested why?
DC electric current depends on DC voltage and battery resistance. So if PA3822U-1ACA has constant DC voltage 19 V for load 0 - 45 W, why other more powerful chargers are not recomended?
Is there any electronics inside charger which comunicates with z830 laptop and limits current (adapt voltage to limit current - so 19V is not constant) ... or such electronics is inside z830?

Portege Z830 - motherboard replacement

Dear All,
My Z830-10f (an Italian model - http://www.toshiba.it/discontinued-products/portege-z830-10f/) core i5 doesn't power on anymore and is giving a 72h code (PPV voltage is not more than 0.68V when the computer is booting up).
After a bit of googling I've understood that the motherboard has a serious problem and should be replaced.
On ebay I've found an used mb from USA but it comes from another model Z830 Intel Core i7-2677M @1.80GHz. Aesthetically the motherboards appear identical, thus I'm wondering if they can be compatible.
I know that I should find the exact spare part, but it's really a jungle and probably all the differences are related to the different codes used worldwide.
Any suggestion is really appreciated!!!
Thanks a lot in advance!
Marco

Hi
From my point of few the new motherboard from another Z830 would be compatible.
The motherboard has exactly the same dimensions but supports just another CPU.
I guess the BIOS would be already available on this new motherboard and the new other i7 CPU supports internal GPU unit (Intel HD Graphics 3000).
Therefore you should not get any problem with the graphic card as well as other parts like RAM or HDD...
I think you should get a shot and go with this mobo.

Battery Calibration and Charge Capacity?

I am currently using a PB G4 15" (high res DL SD) and I've had it for about a month. I just read about calibrating the battery and went ahead and did it. Have I done any damage to the battery or shortened it's effectiveness by waiting a month to calibrate rather than when it was first out of the box?
Also, i also just read about checking the battery charge capacity using the system profiler. My charge capacity prior to calibration was 2731 and after calibration it's 2930. However, it sounds like it should be in the 4400's based on the posts I've read. What do these numbers mean and do I have a faulty battery since it's so low?
Thanks for your help.

Hi Kevin --
Yeah, I'm not loving those numbers you posted either. I'd try performing the calibration procedure once or twice more to make sure that that battery capacity number doesn't change.
The other thing I would do if I were you is download Coconutbattery: http://www.versiontracker.com/dyn/moreinfo/macosx/27425
It's a free app available at versiontracker and it will tell you your battery's original capacity as well as it's current capacity.
I agree with you that a capacity of 2930 mAh after only a month of use and 16 cycles suggests that your battery is defective and should be replaced at no cost to you under the terms of the warranty.
For a frame of reference, after 10 months of use and 166 load cycles, my battery's original capacity of 4400 mAh is now 4228 mAh. No way yours should be in the 2930 mAh range.
When you call AppleCare to arrange for a replacement, if in fact that's what you end up needing to do, the agent you speak with, in addition to making sure that you've properly calibrated your battery a few times (as mentioned earlier) may also ask that you reset your PB's Power Management Unit (PMU). While I'm skeptical that a PMU reset will alter the outcome, you can find instructions on how to reset the PMU here (just in case you need to): http://docs.info.apple.com/article.html?artnum=14449
Good luck and please post back how everything turns out.

PS. You probably know this, but the calibration procedure has been changed slightly for your DL hi-res version of the PB. Here it is below, just to make sure:
PowerBook G4 (15-inch Double-Layer SD)
The battery calibration for the PowerBook G4 (15-inch Double-Layer SD) has been updated because of a new battery released with this computer. With these computers, follow these steps to calibrate your battery:
Plug in the power adapter and fully charge your PowerBook's battery until the light ring on the power adapter plug changes to green and the onscreen meter in the menu bar indicates that the battery is fully charged.
Allow the battery to rest in the fully charged state for at least two hours. You may use your computer during this time as long as the adapter is plugged in.
Disconnect the power adapter with the computer still on and start running the computer off battery power. You may use your computer during this time. When your battery gets low, you will see the low battery warning dialog on the screen.
Continue to keep your computer on until it goes to sleep. Save all your work and close all applications when the battery gets very low, before the computer goes to sleep.
Turn off the computer or allow it to sleep for five hours or more.
Connect the power adapter and leave it connected until the battery is fully charged again.
Tip: When the battery reaches "empty", the computer is forced into sleep mode. The battery actually keeps back a reserve beyond "empty", to maintain the computer in sleep for a period of time. Once the battery is truly exhausted, the computer is forced to shut down. At this point, with the safe sleep function introduced in the PowerBook G4 (15-inch Double-Layer SD) computers, the computer's memory contents have been saved to the hard drive. When power is restored, the computer returns itself to its pre-sleep state using the safe sleep image on the hard drive.

Portege Z830 - screen has been broken and I need to replace it

Hi
I have Toshiba Portege z830. My screen has been broken and I need to replace it.
Is it possible to install some IPS screen instead of original LTN133AT25-601? Which IPS screen is compatible with LTN133AT25-601?

Hi
The original LCD which was used in Z830 was an 13.3"(HD) 1366 x 768 TFT Color LCD.
So if you want to use other display, then you should pay attention to the screen size and the connectors.
I think these are most important key elements.

One User's Story: iOS 7.1 and Battery Life on iPhone 5

I've been reading the messages from folks that have experienced shorter battery life after upgrading to iOS 7.1. It does appear that there is a real problem with some iPhone 5S models. Some of those users are reporting a shorter battery life along with warm iPhones (when the iPhones weren't doing anything) and repeatedly "coming to life" with the lockscreen slider multiple times after being put asleep.
In my case, the day after upgrading to iOS 7.1 I noticed that my iPhone 5 (not 5S) went from about 90% battery to 55% battery overnight--with no apps open. And since iOS 7, I've disabled background app updates, disabled location services for all but about 4 apps, disabled motion, etc. I also tend to never leave any apps open when I'm done for the day. Anyway, during the second night, my phone went from 40% to about 35%. I suspected that iOS 7.1 may have affected the battery calibration but perhaps not the actual life between charges.
I then turned on the phone, set it to not sleep, and let it completely use up the battery charge and to turn itself off. It took a very long time--more evidence of a calibration issue. I then completely charged the phone. Since then, it appears that not only is the battery calibration correct again, but the actual battery life might be a little longer after iOS 7.1. I'm now seeing about an 8% to 10% drop in battery charge overnight which is what I had before iOS 7.1.
I'm not saying that users who are reporting decreased battery life are wrong. I can only report my own experience.

I love all the Tips out there to save Battery life, turn this off turn this down when the bottom line is you shouldnt have to turn anything off or down because those things are why you bought an Apple iPhone, how about Apple fixes there crap right the 1st time instead of ripping us off,
And another thing Apple should reveal there iPhone 6 on what the heck there going to release , whats with all this bullcrap all the time that its a big secret....
Im really getting sick of this Company...

KB article 1490 on battery calibration needs work

http://support.apple.com/kb/HT1490 says:
"Disconnect the power adapter while the computer still on and start running the computer off battery power. You may use your computer during this time."
Does “running” mean something different than “use”? Does this instruction mean the computer should not be allowed to sleep?
[And fix the typo: "still on" should be "still is on".]

Assuming that, then -- do both terms mean the computer 1) can or 2) cannot be put to sleep?
The context here is the instructions are for "Apple Portables: Calibrating your computer's battery for best performance". The instruction in question is #3 for
PowerBook G4 (15-inch Double-Layer SD), MacBook (all models), MacBook Pro (all models), MacBook Pro (17-inch) (all models) and MacBook Air
The battery calibration for the PowerBook G4 (15-inch Double-Layer SD) and any model of MacBook or MacBook Pro has been updated because of a new battery released with this computer. With these computers, follow these steps to calibrate your battery:
1. Plug in the power adapter and fully charge your PowerBook's battery until the light ring or LED on the power adapter plug changes to green and the onscreen meter in the menu bar indicates that the battery is fully charged.
2. Allow the battery to rest in the fully charged state for at least two hours. You may use your computer during this time as long as the adapter is plugged in.
3. Disconnect the power adapter while the computer still on and start running the computer off battery power. You may use your computer during this time. When your battery gets low, the low battery warning dialog appears on the screen.
4. At this point, save your work. Continue to use your computer; when the battery gets very low, the computer will automatically go to sleep.
5. Turn off the computer or allow it to sleep for five hours or more.
6. Connect the power adapter and leave it connected until the battery is fully charged again.
Does the calibration process require, in step 3, that the computer be kept awake? It seems likely, given step 4, that step 3 allows the computer to be in either the wake state or sleep state.
My interest is in clarifying whether the calibration process requires that battery draw-down be relatively quick (as when the computer is awake) or does speed not matter (i.e., the computer can be either awake or asleep).

Portege Z830: Can't install Win7, complains about missing CD/DVD driver

Hi!
I have a brand new Portege Z830 and as usual wanted to start with installing a new installation of Windows 7 x64 (as I don't want the supplied software and can't trust that it is safe anyway). I backed up the entire drive, prepared a bootable USB flashdisk with Windows installation and started it. The flashdisk boots OK, Windows ask me about my preferred language and keyboard, then shows a screen where I can choose between Install, Repair and something else (Recovery Console, I think).
I click Install, Windows starts the installation program aand as soon as a first dialog appears, it shows an error message which says essentially this (it's a translation of my localized Windows' message): "A required driver for CD/DVD drive is missing. If you use a driver floppy disk, CD, DVD or flashdisk, insert it now." And I can't get over this error message. The strange thing is, there is no reason for Windows to require any extra drivers, as it can (apparently) read the installation flashdisk and it can see the ultrabook's SSD, too (can be verified both in the recovery console and by clicking the Browse button of this dialog). So far I tried:
1) Four different Windows 7 images (two of them from MSDN AA, two physical, all of which have been successfully used to install the OS before).
2) Switch SATA mode from AHCI to Compatible.
3) Two different flashdisks.
4) All possible combinations of boot order.
Nothing worked. I even tried e-mailing Toshiba, but all messages come back with "user unknown" (understandable, I had to guess the addresses since Toshiba doesn't seem to provide any official way to contact them - or is hiding it so well I couldn't find it). Does anyone have any idea what I could try next? I rather like the Z830 and would love to use it, but the ability to install my own installation of the OS is essential for me.
Thanks, Pepak

> I even tried e-mailing Toshiba...
Maybe stupid question now but have you tried to contact Microsoft too? If BIOS is OK and if all USB ports are working properly I dont think it is Toshiba related issue. Toshiba offers notebook with original recovery image (WIN7 64BIT HOME PREMIUM) and possibility to create bootable USB with recovery image that can be used anytime you want.
What you do now is your own OS installation. What Toshiba must do is to offer all important drivers, tools and utilities on drivers download page.
What else you can try? Try to obtain external USB ODD and try to install WIN7 using Microsoft installation disc. Im pretty sure this will work.

Re: Portege Z830-11j - Sim card not detected

Portege Z830-11j I have this laptop... it is great,
However the right side drawer supposed to a SIM card is not detectable when it installed.
Is there some lack of software, or other setup required.
Can anyone help?
+Message was translated+

Do you use this notebook with Toshiba preinstalled and preconfigured Win 7 system?
Did you change something in the system configuration?
Is 3G module recognized in the device manager?
Please check this because due to missing and not installed 3G Ericsson driver, the sim module would not be recognized by system and the inserted sim card could not be handled.

Messed up battery calibration

Hi,
I just received my MB Pro today and I messed up doing the initial battery calibration. I assumed the process as the same as my PowerBook G4 (charge battery to full, use computer until it sleeps, recharge again). I later looked up how to do it for the MB Pro and you have to leave it on full power for 2 hours, and then when it sleeps allow it to do so for 5 hours. Is it a big deal that I did the initial calibration wrong? Can I just do it over the correct way without worrying about it? Or is it even necessary at this point?
Thanks

No worries. You can (and should) just repeat it following the proper steps. It's best to calibrate every 2 months or so.
Hope this helps...

Re: VPN doesn't work on my new Portege Z830

I recently bought a portege z830. I installed watchguard firebox vpn connection software but i can not establish a vpn connection. I enter the username and password, the program seems to make a connection but it disconnects immediately. There's no problem with the password or username.
The software works fine in other notebooks. The OS on the machine is Windows 7 Prof.(X64).
Thanks

I really dont know if described issue has anything directly with your new Portege. I presume you need this for your business or you must use it in your company so I strongly recommend you to speak with your local administrator and check what can be done about it.
On this virtual way it is not easy to say what is wrong there. On my Satellite P500 I use Cisco AnyConnect VPN client and it works perfectly with preinstalled original Toshiba recovery image. It is Win7 64bit Home Premium.

Portege Z830 - Recovery DVDs won't boot up

Hi,
I purchase the recovery DVDs from Toshiba to restore my Toshiba Portege Z830. I have tried to boot them using an USB external DVD drive , I have select the device in the bootup menu, but the computer ends up starting from the HDD anyway.
Any help?
Thanks.

Yes, I have tested with other bootable disc and it works ok with them.
Still no joy with the toshiba product recovery discs.

Kernel panic after battery calibration

My aluminium macbook was working nice until I did a battery calibration. Now all the applications are crashing: Safari, itunes, skype... Safari always crashes when I right click on a link and after some minutes the all system just crashed: kernel panic. How can I fix this. Is it a software issue or a hardware one? Does the kernel panic has something to do with the kernel panic?
Thanks for your help

Kernal panics are usually caused by hardware.
