T450s and docking stations : don't understand differences and limitations
Hi,
As you may have seen in my previous posts, I leave my previous company and my good old X220. So I am really wondering if I upgrade or not to the new T450s, or if I search for a X220/X230/T420s/T430s refurbished.
One of my main concern, is the total display size when docked. I used to use quad FHD screens on my old X220, and I was thinking about increasing again the total display size by replacing 2 FHD screen by 1 4K monitor. However, it seems impossible to run 1 4K and 2 FHD simultaneously.
So my question is, Where can I find the differences and limitations of the docking stations available for the T450s regarding the display size ability ?
On the product sheet of the docking stations , Lenovo said "* Some of the video ports have exclusive use and are also dependent on the docked ThinkPad configuration".
Ok, but where can I have this information ?
Many thanks for your answers,

According to https://software.intel.com/en-us/articles/quick-reference-guide-to-intel-processor-graphics,
For HD5500 on U processor :
Independent Digital Displays : Yes (at most, 3 displays may be supported at one time)
Maximum Display Resolution : U-Processors: 3840 x 2160 @ 60 Hz
So 4 displays won't be possible on T450s.
So, I guess, you can run :
1 4K display @ 60hz
OR
something like 3 FHD/WUXGA displays
If someone can confirm...

Try cleaning out the headphone jack with a cotton swab.

I have an airport extreme and express setup. My extreme is in my 2nd floor office with windows facing the water. My dock is about 250 ft away down a very steep hill. I have the express about 100 ft down the hill in an electrical waterproof box attached to a tree as high as I could install. The signal is weak and I'm thinking I might have to buy another express. Any thoughts on the best setup for me. I ultimately want to control speakers(hard wired in) down at the dock with my iphone. I have a receiver coming with airplay built in.
Thank you all for the responses. By process of elimination, I think the problem is the connection to the express in between the extreme and dock. I bought another express and tried it at dock, no luck, I then replaced new express where the one is between extreme and dock, no better. I unplugged the express between extreme and dock and there was no difference. So I believe I am connecting to the airport express or extreme that is inside the house. Again because when i approach express that is halfway I reconnect. so if you can understand my chaos, I believe the express in between is not really connecting to the extreme inside my house. Yes, No? So I need to know how to know if the express half way down the hill is getting the connection from the the extreme in the house. This is wearing me out!!!!!You are asking several different questions. If you need to store your photos, music, and movies on an external volume, you certainly can. Any externally connected hard disk drive will work, connected either directly to your Mac or to your Time Capsule as a shared volume.
You should not rely upon using that as a backup device though. Although you certainly may use it for both purposes, it is a better idea to have dedicated backup devices for a variety of reasons not limited to redundancy. You would not want to simultaneously lose all your pictures as well as your backup. If they are all on the same device, that could happen. Furthermore, a backup cannot back up the volume on which it is running.
As for adding an Extreme or Express, using its LAN port for your iMac, and then enable Internet sharing so you can effectively use the iMac as a "hotspot", you can do that too, but I am unclear on what benefit you believe this arrangement would convey for you.
An Extreme's Guest network is separate from its Main network; that is the reason for having it. -

Go to Settings\Mail, Contacts, Calendars\Add Account (select iCloud)
You can create a new account here ("Get a Free Apple ID" at the bottom) or switch it to another existing account you may have (separate from your Husbands).
Once you tie your phone into the separate account you can go back and delete your Husbands on your phone. -

Thankpad W530 and Docking Station - missing audio device???
I needed to set up a new Thinkpad Minii Dock Plus Series 3/USB with my W530.
First, there was a problem that the computer woldn't "seat" in the docking station. After calling Lenovo Tech support, and not getting anywhere, I individually pressed the "prongs" that stick up from the docking station. There was a loud "click" and several small thingies dropped down into the docking station. After that, the laptop fit right in the way it's supposed to.
I thought I was done, but I noticed an error message on my screen about a device driver error. The Lenovo Technician had me go to control panel > system > device manager..... right click on the machine name, and then click on "scan for hardware changes".
Device Manager didn't show any errors, but doing this generated an error box that said:
Device driver software was not successfully installed
Unidentified device --- device unplugged
High Definition Audio Controller -- ready to use
NVIDIA High Definition Audio --- ready to use
What do I do now? Is my docking station defective? Do I need to plug something into the docking station for this update to complete? The Lenovo tech had no idea what I might do, other than to call on Monday for "level 2 techs".
As a related issue when I went to update Windows, the following update was to be installed:
NVIDIA Corporation - Audio Device, Other hardware - NVIDIA High Definition Audio 3.9 MB
When I try to install this update, I get:
Code 800F020B Windows Update encounterd an unknown error
I think all of this is connected, but I don't see how it might have anything to do with the docking station.
As to the docking station, I tested the power connection (green light is on), a USB port (works), the audio out connection (speakers work fine, with no crackling sound), and the Ethernet connection (works). I haven't yet tried connecting an additional monitor, but that would have nothing to do with audio....This is the Windows update that will not install:
NVIDIA Corporation - Audio Device, Other hardware - NVIDIA High Definition Audio
Installation date: 5/11/2013 2:14 PM
Installation status: Failed
Error details: Code 800F020B
Update type: Optional
NVIDIA Corporation Audio Device, Other hardware software update released in July, 2012

T60p and dock station: can't do the dual monitors
hi gurus:
i have a t60p and a mini dock station. the docking station seems to be working fine execept the problems with dual-monitor function.
1) for some reasons, the laptop lcd always shows up as screen 2 instead of default screen 1
2) tried to monkey around the settings and got messages claimed that i don't have administrative rights to change... blah, blah (i am the sole person using this laptop and i am the administrator).
any idea?
any help will be greatly appreciated.
thanks
_daveHi Paul,
One way to test is to Safe Boot from the HD, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, Test for problem in Safe Mode...
Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive
Reboot, test again.
If it only does it in Regular Boot, then it could be some hardware problem like Video card, (Quartz is turned off in Safe Mode), or Airport, or some USB or Firewire device, or 3rd party add-on, Check System Preferences>Accounts (Users & Groups in later OSX versions)>Login Items window to see if it or something relevant is listed. Or an errant process eating up RAM.
Check the System Preferences>Other Row, for 3rd party Pref Panes.
Also look in these if they exist, some are invisible...

Problem with laptop and docking station
Hello.
We have two laptops with two docking station. Both laptops w/ docking have the same problem:
When the computer is turned off, and its still connected to the docking station, the fan in the computer start to run really fast. The fan goes on for a good while. This is making alot of noise, which can be annoying for the person using the office. When the computer is on, the fan runs at normal speed. If you disconnect the computer from the docking station, the fan stops immediately. Any ideas?
1. Product Name and Number
HP ProBook 6460b
Docking Station VB043AA
2. Operating System installed
Windows XP 32-bit
3. Error message
No error message.
4. Any changes made to your system before the issue occurred
No recent changes.
Thanks in advance.

This question was solved.
View Solution.It is possible the notebook is not completing the shutdown in full when docked.
Make sure the BIOS is the most recent version.
Here is the most recent one to try should you need it.
Other than that, I am afraid I do not have much else for this. I did some research, but I didn't really find anything that was exactly like this. I found scenarios where the fan would run at full speed when docked, but this happened whether the notebook was booted or not. You can try your luck in the business support forums to see if they may have something that is a little more helpful.

Docking Station T430, Graphic interfaces from notebook and docking station usable at once?
Dear community,
I have a Thinkpad T430 and I want to use two external monitors.
The Thinkpad T430 has just one mini Displayport and I do not want to use the VGA port.
So I thought about buying a docking station.
But there are several ones.
I just need an additional (Miini)Display or DVI port.
The question is, if I buy a docking station
which provides an addition Mini Display Port or an additional DVI port am I able to use the one from the docking station and the notebook's integrated mini display port?
Thanks for your help.
Kind regards

Expansion base and dock stations
i love expansion base and my dock station xb3000, the speakers are great, is fantastic, i bought my last laptop because i could connect with, so i want to know if HP is going to do more expansion base,
two years ago i bought a souchsmart tx2 `1015, onlu because had expansion base
now my old presario is to slow, is getting to old...i need to buy i new one very soon, i would like one with expansion base,
so i want to know if HP is going to have expansion base in some new model of laptop notebook
my dock station is a great product
please do not stop to make a good product!Unfortunately docking stations, like firewire ports and pcmcia slots, are disappearing from laptops other than the very highest end business models. So right now no consumer model has a traditional snap down docking station. The only models that do are the Elitebook, Probook, Zbook lines:

Help on assignment, don't understand JOptionPane and showInputDialog
Hi, I am currently studying java and have problems doing my assignment. here is the assignment question. What I am looking for is pointers and hints to start on my assignment. I am not looking for the source code, rather the way to actually understand it and start writting my code
I believe this assignment wanted me to create a class Object called Zeller with the methods in it and a ZellerTester to test the Object?
I read up on the JOptionPane and the showInputDialog, but don't really quite understand it.
Do i need a constructor for the Object Zeller?
Does my assignment require me to put the showInputDialog as a method in the Zeller class? Or put it in the ZellerTester?
The isLeapYear is a method in the Object Zeller?
Here is the assignment question
Examine the method
showInputDialog() and study its function. Note the return type of this method.
Write a program on the following requirements:
1. Use the JOptionPane facility to ask the user for three positive integers,
representing the day, month and year of a date.
2. Use the Zeller�s congruence formula to find the day of the week.
3. Should include a method boolean isLeapYear(int year)
that will return true if year is a leap year, and false otherwise.
The method should check for leap years as follow:
return true if the year is divisible by 400.
return true if the year is divisible by 4 but not by 100
return false for the remaining values
Thank you.I can't seems to return the method back to the main
Not sure where has gone wrong...
here is my code
import javax.swing.*;
public class ZellerTester
public static void main(String[]args)
int day = 28;
int month = 2;
int year = 2007;
int z;
boolean isLeapYear;
String[] displayName = {"Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat"};
if(month==1 || month==2) {
if (isLeapYear = false)
day = day-1;
else
day = day-2;
if(month<3)
month = month + 12;
z = (1 + day + (month * 2) + (3 * (month + 1) / 5) +
year + year / 4 + year / 400 - year/ 100) % 7;
System.out.println("The day is " +displayName[z]);
public boolean isLeapYear(int year)
if (year%400 == 0)
return true;
else if((year%4 == 0) && (year%100 != 0))
return true;
else
return false;
}
