  Wireless Internet

  can use my laptop with internet cable is plugged in, but I am unable to set up a Wi - Fi connection, even though two other laptops in the House are Wi - Fi. Tried the convenience store who said there is a button on the front of the laptop that I push to turn on wireless on, tried that, but nothing is. I have an Acer Travelmate 2410, can someone help me?

  Hi Karldawkins,

  What operating system is installed on the computer?

  As the error message clearly indicates that the wireless switch is disabled on the computer. I suggest you consult the manual of the laptop and try to turn on the wireless switch.

  If you still experience the problem, then I suggest you to contact Acer support to enable the wireless switch.

• Re: Cannot use remote control with my Satellite P20

  I just got hold of a PSP20E and the remote control (2 of them) does not work, the light blinks but that's all. When I try to set up in the Media Center settings, I get the message unable to detect the remote sensor.

  I was told by the previous owner it was working, the only thing I've done is to adapt to a new DVD (TEAC DV-W28E) player and loads of recommended Windows updates. The BIOS version is 1.6 and I'm under Win XP MCE (sp2). Any ideas would be welcome.
  Either by the way, I write a BIOS updated on a CD, or do I have to buy a floppy drive?

  Hello, Alan

  I used Satellite P20 over 2 years and I never noticed any problem with the small remote control. I guess you bought second-hand laptop and in my opinion, the first things you need to do is install the OS via recovery CD.

  When the laptop to factory settings, you must test the operation of the equipment, in particular the use remote control. Recovery image is designed so that everything should work. If this isn't the case, it may be just because of a malfunction of the equipment. As I've already said I used this laptop long enough and never noticed any problems.

  To be honest I didn t make updates because the BONE was very well set up. As I said, you can test it with recovery image.

  The BIOS update you need floppy drive.

• Laptop 2000: use the laptop with battery removed

  Is it often advisable to conserve battery life by removing the battery whenever you have access to electricity? For example others only more often use their laptops on the inside, it's a good habit to remove the battery?
  Also, made a direct power use when the battery is removed likely to affect the performance of the system or cause damage to the hardware components, D.C.
  I ask because I've always liked running 3D applications when using my laptop at home. I use so to remove my battery when its completely charged. I recently met a smell of smoke the fan light but I didn't not take seriously because I couldn't feel it again thereafter. A few weeks back my laptop has plenty of the charging port and would not load or show indicator when charger is inserted. I tested the charger with another machine and it worked perfectly.

  There is no increase in current. Laptops are designed such that the same current is supplied to the motherboard if the power adapter or the battery is used as an energy source. Issues of seizure of power almost always goes back to physical trauma as the connector is twisted or stuck in then just inserted.

  Hello Jessen,

  Thank you for your prompt response and Advisor.

  I have only just open the email, I lost track of it.

  I managed to solve the problem for me, I'm not sure exactly what went right.

  I updated my BIOS from the manufacturer, because it was a new computer.

  I then remove the drivers.

  Remove the data cable to the printer.

  I downloaded all gun pilots, supported software.

  I clicked on the tab of the Windows 7 operating system, but the software is suppose to be ok for up to 8.

  Restarted.

  Then he was allowed, can not have bad luck all the time.

• No sign bar on my blog, using my laptop with Firefox but on IE.

  There is no sign in the space, showing on my blog from my laptop page. I have to use IE to log in using my laptop, but I can work on it fine using Firefox to my office. I tried without the toolbars and it just doesn't appear in the upper right as it does on THE desk or using laptop computer. any suggestions?

  Start Firefox in Safe Mode to check if one of the extensions (Firefox/tools > Modules > Extensions) or if hardware acceleration is the cause of the problem (switch to the DEFAULT theme: Firefox/tools > Modules > appearance).

• Cannot use recovery DVD with my Satellite Pro A300D

  When I arrived at my laptop set up the way I like it, and I created a recovery disk which took the 2 DVD s.
  Then Vista started to slow down a lot so I decided to use the disc and everything started to go well then he asked for two drive and it came with an error message saying that the file was missing to complete the Setup program couldn't t.

  So now I can t get in the menu to restore it to the State when I had and the disks that I don t work.
  Any help is appreciated.

  Thanks in advance

  Hello buddy

  It is badly located now. Please try to do it once more.
  If the same thing happen there is nothing you can do. I'm not an expert for this kind of thing, but I noticed the image recovery recovery DVD will be copied to the HARD second partition disk) first and then the installation of recovery will go from there.

  If the adaptation procedure is not done on the recovery of end procedure cannot be started.
  Sorry buddy. In my opinion, you can try to contact the nearest authorized maintainer and explain the situation. Take the DVD created as evidence and maybe they will order new media for free.

  Good luck!

• Best option to install Windows on a laptop with only of the BIOS

  I have a laptop that is preinstalled with Vista. The hard drive crashed so I had to completely restore, even the recovery partition. How can I LEGALLY install Windows again at the lowest possible cost? The computer has enough features to run Windows Vista/7/8.

  I have a laptop that is preinstalled with Vista. The hard drive crashed so I had to completely restore, even the recovery partition. How can I LEGALLY install Windows again at the lowest possible cost? The computer has enough features to run Windows Vista/7/8.

  Since you did obviously not a backup, has not get and/or do a recovery media...

  Try to get a set of the manufacturer recovery media:
  Lost your Windows disks? How to legally get filtering alternatives,

  Unfortunately - there is no guarantee that the manufacturer of your aura of media in Windows Vista.
   
  After that - you can try to find a friend, family member or just a neighbor who might have a disk of the same edition and the architecture of Windows Vista, you are supposed to use (look for a sticker on the system - perhaps under the battery - that tells you which edition of Windows Vista and the product key) and use it to clean install with your product key.

  After that - your choice could be a friend of tech savvy with a TechNet or MSDN license, which is ready to download a copy of Windows Vista for you and burn it to DVD and you helps to install and be activated with your product key.

  Where you can get into trouble, is that if you can not read this sticker more and your system manufacturer peut/do not send you a set of system recovery media.
   
  The extent of the "pretty good specs" - this isn't your only concern.  If the manufacturer of the computer or of individual components does not support their products with Windows 7 or Windows 8 (so there are device drivers and software out there that allow of such device (s) to properly communicate with Windows 7 or Windows 8 and be fully effective and appropriately used), then you are out of luck.

• Stuck on the second parameter to display on a laptop with only 1 screen

  My son clicked on 2nd screen only on his laptop and the screen became black we can't he come back to normal.  The screen remains black even after stop and turn it back on.  Is there a control function that I can use to go back to the 1st screen?

  OK, I fixed it.  I had to get another monitor out of my old desktop computer and plug it into the laptop.  Then I could see on the screen, we pressed cont + alt + F4, a screen side popped up which had the possibility to the pc screen, the second screen and 2 other screen options.  I just clicked on the pc screen and everything went back to normal.  I don't know how I would have fixed with on the second monitor well.

• Cannot use local shared with replica storage of SSD

  So I had my environment from view for a while and everything works fine, but I have a question on how discovers works with the local replica SSD disks.  I read in the forums and in the document architecture and design if you use a local SSD to store your replicas (that will give you a performance gain), you cannot have your host in a cluster, thus renouncing HA and all the features that come with in a cluster of ESXi.

  However, I meet me a further restriction that I couldn't find any mention of in the forums or documentation, namely that you cannot store the clones in a shared storage if you have a replica on the local disk.  Whenever I got to the stage of commissioning and selected a FC LUN shared as the storage for the linked clones container, the pool would tell me that there not available and there no validation.  However, if I create a LUN that ONLY the host which I use to store the replica on the SSD has access to, then the commissioning is fine.  So my question is this: Why can't place clones related on the shared with a local replica disk storage?  I understand that I will not be able to use the features of the HA, but I would rather just a LUN shared for all clones related to the ease of administration (instead of having to create one for each host).  If someone could tell me what I'm doing wrong or explain to me why this is the case, it would be great.

  OK, I found the documentation indicating that "If clone related data warehouses are shared, the replica data store must be shared. Replicas can reside on a store of local data only if you configure clones all connected on warehouses of local data on the same ESX host. "Who is on page 14 of the document storage considerations see here: http://www.vmware.com/files/pdf/view_storage_considerations.pdf. However, it does not explain why this is, he said only that it is so.

  So as a result of this requirement, it is logical that linked clones on a present at a single ESXi host LUN would support, but without link clones on a LUN present at multiple ESXi hosts.

• Cannot use a pfx with no password file in a KeyManagerFactory

  I have a pfx file that contains a private key and a corresponding self-signed certificate. The file pfx itself is not protected by a password. I can't use this pfx file to initialize a KeyManagerFactory to establish a SSL connection.
  
  Here's some code that shows what I'm trying to do:
  
  InputStream ksStream = ResourceReader.getResourceAsStream ("< pfx-file-location-on-file-system >");
  Char [] password = null; given that the pfx file has no password on it
  Keystore keyStore.load (ksStream, password);
  
  KeyManagerFactory kmf is KeyManagerFactory.getInstance ("SunX509", "SunJSSE");.
  KMF.init (keystore, password);
  
  This operation fails with this exception:

  This code works fine if I set a password for the pfx file, and then use this password to load the keystore and then use in the KeyManagerFactory.
  
  My question is: why can I not use a pfx file that doesn't have a password on it?
  
  Thank you
  R.

  The actual code used to extract the key private key file is in the sun.security.pkcs12.PKCS12KeyStore.engineGetKey () method and the private key decryption code fragment OpenJDK version

                 SecretKey skey = getPBEKey(password);
              Cipher cipher = Cipher.getInstance(algOid.toString());
              cipher.init(Cipher.DECRYPT_MODE, skey, algParams);
              byte[] privateKeyInfo = cipher.doFinal(encryptedKey);
  
              PKCS8EncodedKeySpec kspec = new PKCS8EncodedKeySpec(privateKeyInfo);
  

  There is therefore no conditional autour decryption he always tries to generate a PBE key, even if no key is scheduled and then decrypt with it. Of course, it could be a password less pfx file actually has a default password, there must be a request for change (PKCS12 perhaps) that covers it, but I bet that means really that without encryption is done. Assuming that the PVE in JDK1.7 code differs little of this and that have no password really means that there is no password so that there will be no way in which we can use the Sun provider to access the private key.

  Like you, I found that BouncyCastle can handle this situation but if you really cannot work with BouncyCastle then the only alternative I can think of (that do not required a ton of code to write) is to use OpenSSL to change the pfx to a default password password. If all the machines that use your installed OpenSSL code it could be done within your Java ProcessBuilder using code. Not very attractive, I know, but given that the PVE cannot handle the password less pfx files you have to use a very attractive solution.

  To create a new pfx file with a different password seems to take two OpenSSL commands: -.

  OpenSSL pkcs12 - in cert.pfx - by fred
  followed by
  OpenSSL pkcs12-export - in fred-out fred.pfx
