• Note K5 Lenovo VIBE does not detect device Bluetooth Jabra

  Hello

  It's disappointing to start with. Less than 24 hours since I got my hands on the new Lenovo VIBE K5 Note.

  With long journeys to work and given the connectivity bluetooth with the phone is an essential feature to have for me. It worked very well with my previous Samsung phone. However, the same bluetooth device Jabra is getting not even detected in the new Lenovo VIBE K5 Note.

  Please suggest a solution as soon as possible.

  Waiting for a quick solution and intervention.

  Tejas Jani

  It's weird... I used many devices different bluetooth, including headphones and stereo speakers. A connected with bluetooth BMW and mercedes. Sometimes look a little longer and matching is always a concern on ANY bluetooth system.

  But once it is coupled his uber fast. What rom are you on? Already point Marshmallow?

  Is the problem still not solved? You reassign your jabra to sail again?

• I found anti-phishing on our two PC with Firefox (now 31) was NOT enabled by default, (I do not disable). Discovered this bug after a phishing attack.

  Hello

  I posted this more as an info. I use Firefox 31 on two PCs. and had a phishing incident today. I read your article on Firefox from Ant-phishing / anti-malware protection and using the two test pages you provided, I found the phishing test page has not been blocked. I followed your instructions and successfully activated. For some reason any on my two PCs (one is Windows Update 1 8.1 and the other an old XP machine) only anti-malware was running. Both computers have been updated to version 31 in the last days. I don't know if the lack of anti-phishing enabled by default is a bug in this version, or has been copied to a framework of an earlier version of Firefox. I had never changed the security settings myself on any version of Firefox.

  This isn't really phishing, which sounds rather like malware. Try to run some scans. Troubleshooting Firefox problems caused by malicious software

• Keyboard does not not on Lenovo laptop.

  Hello. I have problems with a Lenovo laptop. I can't connect to Windows because the keyboard does not work normally. The 'H' button works as a return back, for example, and I don't see what I'm typing in the password bar, I don't know what keys are what. Only a few keys to produce characters and when entering keys other system sounds right. I had this problem yesterday and I fixed by holding button FN and F4 or F7, I think it was F7, but now the same combination does not work. If you could help me that would be great. See you soon.

  I've identified the problem.

  Lenovo machine think that is pressed the CTRL key for an unknown reason. I googled and it seems someone else has the same problem with their Lenovo machine and they have an external mouse Logitech installed, I have so it would be a huge coincedence so those not bound.

  Is there a way to use the features of the arrow by pressing CTRL? Y at - there combinations like CTRL, ALT and 8 = arrow down for example?

  If so I can at least start mode without failure.

  See you soon.

• Does not have Lenovo Slim USB Portable DVD burner DVD or programs

  Hi everyone, yesterday I bought a new Lenovo Y50, but when I tried to launch a video game he acted as if there were no disc inside the dvd recorder.

  The strange thing is that it turns CDs without problem, but no dvd or programs.

  I just bought, so there is no possibility that my pc is affected by viruses or other issues don't related.

  Can someone help me?

  Is this just a problem about me being not not good for the pc, should I make a process specific or is - a problem the burner dvd itself?

  Thank you.

  Thank you for your answer, but I solved this problem.

  I went back to the seller, we tested it and the result is that it is broken.

  They gave me a new, and now it works correctly.

  Thank you once again.

• Channels not defined in Combo Box Bug?

  I found a problem with the drop-down list box control:

  1. create a drop-down list box and deselect 'allow Undefined Strings.

  2. run the VI

  3. Select a list box item

  4. press on the BACKSPACE key to remove a few letters of the item

  5. click on on the front panel

  The combo box is filled with a string not set!

  Disabling the BACKSPACE key is not a valid work-around because the user may need this while typing the value.  Expected behavior of the control would be to restore the previous value.  Any comments?

  Yes.

  Take a look at the bug report in this thread.

• Vibration does not work after update Marshmallow

  Vibration worked before update to the marshmallow. After the upgrade to MM vibration no longer works. Someone else with the same problem? Someone at - it a solution?

  Fortunately, this was caused by the battery saving function. I had not read well enough information when turn on. Strange that the diagnosis function is not to replace the parameters and vibration on.

• Important NOTE about passwords in bios bug!

  Hey everybody,

  IM the proud owner of the laptop Lenovo SL - 500 series. I never had any problems until today:

  I decided to add a supervisor and Boot password in bios to better secure my files, I found a huge problem here and I found the solution that perhaps others would like to know too:

  Example:

  Ive like password "abc123 #1" in the bios, he asked me to confim this password and I did it. All is well until now.

  I restart my laptop and he invites me to type my password to start:

  Password: "abc123 #1.

  Jim

  Hey now, that's strange, the password that I just put refused. (Stress level was up to 90% instantly, cause as you may know Lenovo data security is so good that you would need a new motherboard if you can't get the password!)

  I have tried tons of passwords but he refuses the password. Until I found the problem and the solution of a lot of luck!

  the symbol # is NOT handled correctly in the bios. If you set the password, it allows. If you try to change it and retype the password it allows. But when you're out of the bios and the password prompt is displayed. It wil not understand the special symbol.

  What causes your password not valid cause is not the 'same' password.

  Solution:

  I replaced the # with the TAB key on my keyboard

  So instead of typing the # I knocked my TAB key once (Yes it magicly is considered as a symbol).

  So that was my password 'abc123' TAB '1 '. Instantly my laptop boot and I was able to access the bios again and remove my password set using the TAB key instead of the special symbol # in my password.

  So for future reference: do not set a special symbol like password in your bios. Even if she acts as if it was OK. It will be brick your laptop and it will cost you a new motherboard if you find out what the symbol is replaced by.

  In my case No. == TAB, I don't know what it is for other special symbols and im going to try it!

  I hope that people will appreciate this information and this will help other people who accidentally brick it portable by applying a special symbol in the password here!

  Other users of Lenovo good luck!

  Séverine,

  Thanks to consolidate related topics. Based on these discussions, their solution was to omit the special character when access to the bios, but this current thread's advise to use a different key replaces a special character. However, it doesn't matter as the most important thing is to ban the use of special characters in the first place. Don't you think?

  Technokiddy,

  I reported this problem and advised him to consult the version 1.28--> update BIOS (Bootable CD) - ThinkPad SL300, SL400, SL400c, SL500, SL500c

  Before you can update this new bios, make sure to disable the BIOS password avoid any unexpected errors.

  Problem fixes:
  -Improved password security.
  -Fixed an issue where the LCD brightness setting could not wo

  However, I do not know if the use of special characters are not allowed or not in an attempt to put in place a new password.

  There are a few questions that I need to confirm double with you also.

  1. Could you tell me how you insert the special character ' # ' for supervisor password?  The English keyboard layout and Netherlands's character "#" is given by shift + 3
  2. Are you sure you selected character ' # '?
  3. Go to the windows Notepad and press the same button that you press is the BIOS password settings. What character do you see?
