AC adapter for Portege R830

Hi there
I own a Toshiba Portege R830 (P/N PT321U-04S019B).
It's original AC adapter was lost a long time ago so I brought chinese analogue, that turned out to be no good.
Now I want to buy original one. But I can not find out its model. I only remember that it's output was 75W.
Another point is that I've changed my laptop's battery to 9-cell. Do I need more powerful AC adapter now?
Would you please tell me what do I need to buy and is there some place where I can buy original parts from Toshiba?
Thank you!

Even if you replaced the battery with a stronger one, you dont need another, stronger AC adaptor.
The battery charging procedure will take longer but I guess this should not be a big issue for you
As mentioned by Dr.Lamp; the new AC adaptor should support the 19V and 3.42A
The Volt value is very important and you need exactly the Adaptor which meets this 19V requirement. The Ampere (A) value can be little bit different but should not be too low.

  • What is new in BIOS v3.0 for Portege R830, R840 and R850 series

    Hi
    Toshiba released updated BIOS version 3.00-WIn on the 11/08/2011.
    Has anybody installed this and/or know what it covers?
    I hesitate to install without knowing what may be altered.
    Many thanks for any comments.

    Hi
    As far as I know Toshiba European driver page does not provide details what has been changed in the new BIOS versions. But I found the Toshiba US driver page and there you can find all the details about the BIOS changes.

  • How to Disable WiFi for Portege R830 + Port Replicator& External Keyboard

    Dumb questions I'm sure, but this is driving me nuts.
    I have a Port Replicator with external keyboard and monitor attached. The Port replicator has an wired Ethernet connection to my LAN. When I dock my R830 into the Port Replicator I'd ideally like it to turn off the wireless adapter, but as a minimum I definitely want it to default to using the wired LAN connection not WiFi.
    Currently it just seems to randomly decide to either use the wired or wireless connection when I dock.
    So ... two part question:
    1. How can I set the R830 to automatically default to a wired Ethernet connection when I dock?
    2. How can I disable the wireless connection when I'm docked and using an external keyboard (the F8 toggle to turn wireless on/off on the laptop keyboard doesn't work on external keyboards)
    Many thanks in advance for your advice.

    > How can I set the R830 to automatically default to a wired Ethernet connection when I dock?
    If the port replicator is connected to the LAN then the notebook would use the LAN connection automatically if you connect the R830.
    > How can I disable the wireless connection when I'm docked and using an external keyboard (the F8 toggle to turn wireless on/off on the laptop keyboard doesn't work on external keyboards)
    Well, in such case you can use the internal keyboard to switch off the Wlan using Fn + F8

  • Re: Portege R830 - Can't find my model on the Product Support list

    Hi everyone,
    I recently bought a Portege R830 and was trying to find the support page for my model.
    However on the Product Support list, where you choose the model, I can't find which one is mine.
    My model is displayed as *R830-1056UB* on the box the laptop came in and it simply says *Portege R830* on the underside of the laptop.
    There are several entries for R830 on the Product Support list, but *R830-1056UB* is not one of them.
    *Any ideas how I can decide which one is mine?* (I'm worried about downloading wrong software/drivers for my laptop)
    I'm not in a country with a support phone number and it seems Toshiba support don't have an email contact, so I haven't been able to contact Toshiba directly for help.
    Thank you in advance for your time and help!

    Hello
    I dont know which Toshiba support page you have checked but if this notebook is designed for Asian market you should find it on Toshiba Asia support page.

  • Does the Intel 82579LM NIC on the Portege R830 support Promiscuous mode?

    Hi,
    I've got a work laptop (Portege R830), which doesn't want to sniff packets. I've got it connected to a Netgear Hub (DS104), along with an older notebook, and then uplink to ADSL.
    Running a continuous ping to the default gateway and Wireshark on both devices and the other computer can see the pings from the Toshiba, but not vice-versa.
    The Toshiba is running as an Administrator account, has the Windows Firewall disabled, and my Symantec End Point Encryption disabled. I don't have any other AV to my knowledge.
    Does anyone have any ideas of services I should disable/enable, or knowledge of the features of this NIC?
    According to the Intel site "Yes, all currently marketed Intel PRO/100, Intel PRO/1000, Intel Gigabit, Intel PRO/10 Gigabit, and Intel 10 Gigabit adapters support Promiscuous mode. " But the Intel 82579 Gigabit Ethernet Controller is not in the list that follows on; http://www.intel.com/support/network/sb/CS-004185.htm?wapkw=%28promiscuous%29
    Thanks for your time.

    Usually the firewall or Internet Security software blocks pings so perhaps try uninstalling Symantec completely. Just disabling it may not disable everything.
    Another thing to try is use a Static IP Address instead of DHCP. Disabling IPv6 or installing a newer LAN driver from the Intel website may also help.

  • Portege R830 - Windows won't start after I install Comodo Firewall

    Good afternoon,
    I purchased today a Portege R830, and after the Windows configuration was over, the first program I installed was the popular free firewall Comodo. After I rebooted, Windows 7 wouldn't start anymore. It would get stuck on the user login screen and I know it's a problem with the firewall because if I make a system restore to the restore point created by the firewall installer, the windows will start again.
    So I ask if there is any incompability between the firewall and some software on the Toshiba. Has anyone ever had this problem? I've been trying to solve this issue all day long with no results. I even re-installed Windows 7 using the Toshiba recovery and the issue persists. I really love Comodo, and I want this firewall on my laptop, but Windows just won't start!
    Any help would be very apreciated.

    Hi jillefsky,
    Have you disabled the Windows firewall before you started with Comodo firewall installation? As far as I know Portege R830 is delivered with preinstalled McAfee security software and you should remove this program before you install any other security tools.
    Generally speaking this issue has nothing to do with Toshiba and its recommendable to contact Comodo directly. Maybe they know about this issue so they can give you a proper answer.
    But I dont understand why this program is so important for you. Windows has already an internal firewall so such programs are not necessary in my opinion. Just install a good antivirus program like AntiVir and activate automatic Windows updates. Thats all!

  • Portege R830 - Can't turn off touchpad

    Hi, strange issue. But cant turn off the touchpad on a Portege R830 (Windows 7 32bit). I have seen this problem on both of the machines I have. This has never been an issue for the Tecra models I've had, M5, M9, M10, M11, R840 etc.
    I have the latest Alps driver installed, from Toshiba.co.uk. I have tried the button on the touchpad, this does not work. The Alps device cannot be disabled from Device Manager. I have tried the Toucpad properties from the System Tray, Advanced Tab, Advanced Settings. This does not have a simple "turn off touchpad" setting. It does have an option to turn off the touchpad when using a USB mouse - however, this also does not work.
    Can anyone help with this? The only other option I can think of is the BIOS, but this would not suit my users, who may want to switch it back on again at some point while running Windows.

    Hey,
    Yes you can disable the tapping function in mouse settings. Navigate to control panel > Hardware and Sound > Mouse > Advanced > Advanced feature setting and uncheck the tapping function.
    The user Xardas did post some screenshots in another thread how to do this:
    [Tecra A11 - How to change touchpad sensitivity? |http://forums.computers.toshiba-europe.com/forums/thread.jspa?threadID=59356]

  • Some function keys are not working on my Portege R830

    Like others, I have a new Portege R830 and experienced the sudden unexplained loss of functionality of the 13 function keys. My os is a native windows 7 64bit install, with office 2010 installed afterwards. I have the SSD model.
    I followed the instructions, removing TVAP and re-installing, and I have both VAP and flashcards operational. I used the USA site drivers for the latest set (the Australian and European driver sets are older versions and different).
    Most, but not all, of the function keys are now working again. What isn't working are as follows:
    - F12 functionkey not operating
    - volume up and down keys not operating - what I am most interested in - any suggestions on how to get functional again please?
    also, on re-installing VAP, I lost functionality on ecobutton. Any suggestions on how to get working again?
    thanks in anticipation

    Hi
    You are on the right way dude the VAP and Flash Card Support Utility controls the FN buttons. If you have an European notebook model, I would recommend using the drivers from Toshiba European driver page but generally speaking there should not be a difference in the software
    However, in my case restarting the Flash Cards helps to get back the FN buttons functionality. The Flash Cards can be found in All Programs -> Toshiba -> Flash Cards.
    So check if restart would help you.
    Regarding the Eco button: ECO Utility controls this button tooso would recommend installing/reinstalling this software beside the VAP

  • Portege R830 - Forcing mobile broadband to use 3G/HSDPA with Win 8

    Greetings all,
    Upgraded my Portege R830 to Windows 8 with no problem.
    Since most of the Wireless Manager functionality has been moved into Windows, I can't find where I can 'force' the connection to 3G/HSDPA.
    I live in an area where the signal is marginal and if I leave the network settings as default, it frequently switches to the stronger EDGE connection. With Wireless Manager, I connected using only 3G/HSDPA where 2 bars were sufficient for daily tasks.
    Any light bulb moments? (Moving is unfortunately not an option ... ;) )

    Hmm I think such setting isnt available in Win 8.
    Microsoft provides a nice article about the broadband configuration using Win 8 and the mentioned configuration isnt there:
    http://windows.microsoft.com/en-us/windows-8/mobile-broadband-from-start-to-finish
    So from my understanding the best broadband signal will be chosen and used if its available.,

  • Portege R830-10R: No USB connection after recovery from sleep mode

    Good day!
    I've been experiencing the following problem on my Portege R830-10R for a long time.
    Quite frequently, when it recovers after sleep mode it loses ability to recognize connected USB devices and built-in 3G modem does not work as well.
    After some time, like 10-15 minutes of working (or never), the problem becomes solved by itself, but normally it is not the case.
    If I try to send the laptop to hibernate or sleep mode again, while this problem is active, lets say, it does not hibernate and hangs on a half way with a black screen - so I have to shut it down manually and then start again.
    Normally, the only way to resolve the problem is to restart it, but the issue comes back after next sleep mode.
    Has anyone had something like that? Any solution available?

    > {quote:title=Paolo30 wrote:}{quote}
    > It would be interesting to know, if the same problem could be replicated after the notebook has been recovered.
    > I mean you that you should run an system recovery (Toshiba recovery disk or HDD recovery).
    > Straight after the system has been recovered, test if USB ports would functions after waking up from sleep mode.
    I agree that it may resolve the issue, I tend to see the root of the problem inside the software part.
    However, I was curious to know whether it was possible to treat it without recovery - I have a lot of software installed and complete recovery of the laptop to the state as it is now may take several days.
    Anyway, great thanks for your help!

  • Portege R830 - Information request

    Hello,
    i have a Portege R830-10R, does it have SATA III?
    Will I notice a big difference if I decide to change to na SSD and add 4GB memory?
    Thanks in advance for any reply!
    Have fun!

    Hi
    I have an Portege R830. If you are asking about adding 4GB of RAM - I guess you're running a 64bit version of windows. I'm running a 32 bit version (for software compatibility) - so can't comment on the effectiveness of upgrading the RAM in this specific instance.
    However I have installed a Samsung EVO 750 GB SSD.
    This - in my view - has made a significant difference. Boot time is halved and in general opening a programme (such as PowerPoint) feels almost instantaneous.
    On other PCs I have - the 'adding RAM' trick is something I've done - and it makes a difference. The SSD has been more impressive. I'd do it - but be careful about which SSD you choose. After much research - I'd only look at a Samsung.
    Hope this helps.

  • Portege R830 - Free WiFi not working

    So pleased my wife bought me a new Portege R830 for my 60th birthday.
    Went to Wethersppoons to use their WiFi as I haven't got WiFi at home, and took that and my old clunker laptop.
    Cannot get my R830 to work at anything over a dial up speed and then clicks off when I open new content.
    My old clunker, sitting next to it works fine.
    Any ideas, could it be security settings, or what as the WiFi is clearly working.
    At my wits end, please give ideas before it goes through the window in frustration.
    Thanks

    Hi
    >It will connect, but so so so slow, slower than dial up
    You are using an open and public Wlan so theoretically it could be an Wlan router issue.
    I would recommend checking the Wlan performance with another wireless lan in your environment.
