• Satellite U400 - problem with the new extension to 2 GB RAM

  Hello

  My satellite U400 have 3 GB of DDR2 memory. (2 GB DDR Kingston PC5300 + 1 go)
  I tried to put 4 GB of RAM (2 x 2 GB DDR2 PC5300 Kingston).
  But I have the blue screen on startup of windows.

  Each extension RAM works very well (try with 2 GB of RAM only).

  Windows 7-64 bit / CRUCIAL M4 256 GB HARD drive.

  Do you have any solutions?

  Thank you.

  Can you please post exact model laptop (U400-xxx)?
  I just want to which Kingston modules are 100% compatible with your laptop satellite.

  I can only imagine that you are using incompatible Ram. All compatible modules will be recognized correctly and you will be able to boot your laptop as usual.

• Satellite L300 - problem with the battery and with the FN keys

  Hello

  Please help me with the following 2 problems:

  1. I bought 10 L300, 2009 with Vista, and then I switch to Win7. After that the FN do not work. I can use a couple of access keys, but anyway, they do not appear on top of the scr4een as if it was on Vista. You have the solution to work again?

  2. after the upgrade to Win7, my battery is almost dead. I use 230V taken to work on my laptop. I used my laptop properly and it is really surprised that the battery had a life so short. You have a similar experience or you may have a solution to work again?

  Thanks in advance for your help.

  (1) install VAP (value added package) and Flash memory card Support utility.
  For example, you can find the driver area L500 software.

  (2) you can try to define some battery saving options in the power management Windows 7 in order to reduce the working time of battery.
  I switched to Windows 7 and the battery still works fine.

• Problems with the touch screen of HP all-in-One after upgrading Windows

  I recently updated my version of Windows (64-bit) with system updates and then a full version updated to version 8.0 version 8.1.  After the update is complete, I started to experience a strange problem with the touch screen on my HP Envy Rove.  The screen would flash repeatedly one set of points in the right lower quadrant of the screen as if the simulation random screen button.  There is no way to stop this.  If the screen on a keyboard was pulled up, letters in the place of the flashes would be broadcast in the fields on the screen.

  The only way to stop the flashes of screen has been to go into the Device Manager and disable the HID-Compliant device driver.  It stopped (system generated keys) flashes, but also disabled my touch screen input.  So now the system is usable, but without the benefit of the touchscreen.

  Here is the information on the driver:

  HID-Compliant device

  Date: 21/06/2006

  Version: 6.2.9200.16851

  (input.inf)

  I tried updating the driver, but this seems to be the latest version available.  Go back to the previous version of the driver, could solve the problem, but I could not locate on the support web site.

  Any suggestions on how to solve this problem and re-enable the ability of my touch screen?

  Hello

  Downloaded drivers from the manufacturer will be the most tested and up to date available. The best place to download a driver is directly from the manufacturer of the equipment.

  So I suggest you to install the driver that is available on the HP website for your model.

• HP 15 laptop: problem with the touchpad and the key "stuck."

  Hello!
   
  Last weekend, I have an irritating problem with my HP 15 laptop. Bought two years ago and upgrades to Windows 10 a year ago.
   
  First of all, my touchpad started to not work properly. It "freezes" and I can't use it until I click the ESC key, but it doesn't last and "freezes" again a few seconds later. Then, everytime I open a window where there is a text box (Start menu, edge browser, Control Panel, etc.), the number 5 is entered automatically and permanently, as if the button 5 has been blocked. I did a quick check and button 5 do not seem physically stuck.
   
  Yesterday, I restored the system to the factory settings, so I'm back to 8.1 for Windows and then upgraded to Windows 10. Everything seems to work fine, but this morning, the problem was back. Is there something I can do? What is the problem caused by Windows 10 or the computer? Should I restore it to Windows 8.1? Everything worked great til last weekend, I don't know what that was.
   
  Thank you in advance for your help!

  Welcome to the HP support community @gouch3.

  I understand that you have a problem with the keyboard and the touchpad on your laptop from HP 15.

  Have you tried to use a keyboard external and mouse at all?

  Have you tried to go to Safe Mode to see if the problems persist in there?

  Have you tried to perform a material or forced reset Reset?

  Did you do a test of material?

  Have you updated your drivers?

  It could be a driver problem to be able to look at that for you, I need your model number. I wish I could give you an answer or not, but at this point without the troubleshooting results and the model number, it is difficult for me to say.

  I can say that if everything works in point 8.1 of Windows without problem, the driver TROUBLESHOOTING is a great place to start. Please try to follow these steps for the keyboard and the touchpad of troubleshooting:

  • Beginning
  • Search for Device Manager
  • Search results, open Device Manager.
  • Click on display
  • Show hidden devices.
  • Click the arrow next to keyboards.
  • Right click on the name of the keyboard device.
  • Select uninstall.
  • Continue deleting the names of devices in the category keyboards until the feature of all the names have been uninstalled.
  • Restart the laptop twice.

  Touchpad:

  • Type of research, "Device Manager."
  • Click on Device Manager,
  • Expand mice and other pointing devices.
  • Right click on the TouchPad,
  • Click on uninstall.
  • Restart the computer laptop twice,
  • Reinstall the TouchPad card.

  I found a document of troubleshooting for you to try also called Portable keyboard troubleshooting. Please be sure to follow the steps described in this document.

  The best document I have for TouchPad problems is the use and troubleshooting of the TouchPad and ClickPad document. 

  Here is a link to the HP Support Assistant, if you need it. Just download and run the application and it will help with the software and drivers that need to put up-to-date.

  This is a great question other clients may also be questioned. When we came to a resolution, please share what has worked for you with others by marking this post as an acceptable Solution. If you want to show appreciation for my efforts today, please take a second to click the Thumbs Up button below.

  If you need assistance, I would be more than happy to continue to help you. Please re-post with the results of the resolution of the problems. Could you please also provide your model number (How can I find my model number or product number?)

  Thank you!

• Problem with the report and the system of axis 2d

  Hi, I'm trying to write a script with tiara, who wrote a 2d axis system in the report but I'm having a lot of problems with it.

  What I'm trying to do, is make 3 or more system axis 2d in the report, each displaying a part of the data of 2 channels (x = ch0, ch1 = y).

  With only 1 graphic I get what I want, but when I try to add the 2nd or the 3rd, they show without my defined x-scale and with the offset x different from the first chart.

  I tried everything, but I could not remedy

  I added as attachments the .csv file that I use to ch0 and ch1 and 2 screen shoots "what I get" (about the problem with the script) and "what I hope to get" (done manually, is what I'm trying to get the report)

  Hi lerman,.

  Here is an edited version of your code that works on my computer.  A problem that I know that I fixed it was that your presentation of the STATE was in the name-oriented mode but you use the variables based on the number to assign it X and Y channels.  The execution of these commands in a loop FOR makes it much easier to debug the code and to avoid any annoyance at first.

• Problems with the date and time - have to reset the date & time on reboot

  original title: problems with the date and time

  Whenever I turn on my computer (Windows XP 2002) I click on F2.  Then I re - set the date and time it occurred in January 2006 1 h every time I have turn off the computer.  Can someone tell me what I need to do?

  You need to replace the battery in time clock (RTC) real of your computer.  It can also be called the CMOS or BIOS battery.

  Many computers, this battery is an inexpensive CR2032 button available in almost every pharmacy corner.  There are, however, some computers (especially laptops) that require a different (and probably more expensive) battery.

  Whatever the expense, almost all of these batteries are easy to replace.

  To get help, post back with the brand and model of your computer.

• Photoshop elements 13 said that there was a problem with the download and recommend exit us and restart

  We bought a new laptop and 13 items today. We spent the day trying to get it set up. We tried to download the 13 items at least 6 times. Whenever it took about 45 minutes to download, but when we open the file and click on set up it says that there was a problem with the download and it recommends that stop, restart and download it again? How we work what goes wrong? We had to remove the files and start every time. I don't have another day to try to get this sort. Should not it is just a matter of downloading and then, should not come with a message to install and we just press Yes and it works.

  You can also download the trial version of the software directly (No Download Manager) through the page linked below and then use your current serial number to activate it.  You should get two files, an executable file and a compressed file.  Run the executable file and it will install the rest.

  Help, I have a problem with the PS and CC - I get and error measure in PS - "this program cannot start because ONCoreFoundation8.dll - is missing... and it crashes, and now creative cloud will not be open to all."  I spent more than 2 hours to speak to someone in tech support that I did not understand, and I don't know what to do next. The tech gal was run, but once she hung up he returned to broken.  I have an idea, but that's just a guess - trouble started about the time I tried to open On1 of ps there has been a perfect icon effects 9 (for some reason, they decided to add the icon when I got it - I have 8) I clicked it and it loaded the update and then asked me if I wanted to try or buy - that's when I realized that I should have clicked on 8 and tried of back , but is either too late - I think, maybe this dll. 8 or 9 in with perfect On1 effects - and it has changed my settings in PS - and is the reason why it is not compatible - ideas? I have a pc with window7-Carol

  Try to run Photoshop without loading third-party plug-in. hold SHIFT keys when you start Photoshop.  The missing module is not Adobe software.
