  After the closing start system again that the screen was completely black (no cursor even), but I can hear that the system is running in the background. He helped bring my laptop for the sleep/hibernate and wake up again. Black screen does not appear if I use sleep/hibernate implementation, but only if turn off pc by shutdown system.

  I have install the ati drivers for vista support page lenovo T60, avoiding "setup.exe" and ccc, only pure graphics driver, installed through properties of the graphics card.

  Earn 8 x 64 this method works very well, the 8.1 looks the same, but then this problem with black screen appeared.

  This is my new tablets...

  (Sorry for my bad engglish)

  Hi Grenven,
  Do what I say to reset (restart) your Tablet: -.
  --> Memory location opened by card (SD card).
  -> Take something thin and sharp as a safety pin or a toothpick.
  -> Now, you will see a small hole like structure near SD card slot. (In fact it looks clearly if there is something on the inside, but there are.)
  -> Spend your pointy thing in this hole up to a certain distance. (Pass slowly inside until you hear a clicking sound)
  -> Who has the reset button which will restart your tablet of any situation.
  -> Do not lose patience while finding the reset button. Do what I say and your tab will be back normal. Find it for the first time is a little more difficult but follow my steps, and you will get it.

  Good luck...!!

• Help! My Lenovo T60 Thinkpad too slow for life...

  Hello

  So I got my Lenovo T60 for like a year and a half, and until two months ago, it worked well enough (he got the occasional fan at first error message place however) and then all of a sudden he started bluescreening, as it would not go past the Welcome screen. So I installed Windows 7 and it worked fine for 3 weeks, then again bluescreening. So I decided to go back to XP. Establishment lasted 2 days (no, I'm not exaggerating) and since then, it takes 30 minutes just to start. And although I can't do anything on this issue because it is too slow; a simple command such as opening a folder takes 10 minutes! Has it damaged something by installing Windows 7? What can I do to make it normal again? Thanks in advance

  Looks like a bad HD for me. You need to check the bad sectors, which can be easily made to initialize with a linux LiveCD/USB and by running disk utility it. It will report on the SMART status of your drive, and I suspect that your HD to be riddled with bad sectors, ergo long boot time and BSOD.

• After the last update on Wnidows 7 Firefox opens just a blank screen (black).

  After the last update Firefox on a machine Wnidows 7, Firefox opens just a blank screen (black). It worked fine until the latest update. It does not open in "safe" mode I tried several facilities clean and using various other compatibility settings. I also tried various changes of display. Closing X is still under the black forest as I can by conjecture activate this.

  Get a black screen after updating to Firefox 33 can be caused by a problem with hardware acceleration in Firefox.

  You can check if there is an update for your graphics display driver.

  Try to start Firefox in Safe Mode by holding down the shift/Options key.

  Disable hardware acceleration in Firefox.

  • Tools > Options > advanced > General > Browsing: "use hardware acceleration when available.

  You will need to close and restart Firefox after enabling/disabling this setting.

  If you haven't tried the "last known good configuration" among the Advanced startup options then do that first.  If this does not help, you must run the System File Checker to search for possible system problems.  Then, you must run the upgrade from the system tool and then see if you are able to run the SP2 update.   Mike - Engineer Support Microsoft Answers

  You need more that just run the downloaded exe file.  Run this file (77a224ww.exe) just to extract the necessary files and puts them in a directory on your hard drive.  It does really settle anything.

  Did you read the Readme, particularly the "installation instructions"?  Have you noticed that you need to uninstall any previous drivers before installing the new?

  • Start the Device Manager (start > run > devmgmt.msc > OK)
  • Click on the + sign next to "audio, video and game controllers".
  • Is there an entry in Audio device to 'SoundMax Digital Integrated' Manager?

• After you have installed the latest Windows updates, Lenovo T60 laptop running Vista takes 30 minutes to start

  I have Vista Home Premium installed on a Lenovo T60 laptop. The machine is
  3-4 years.

  Although the system has never been quick to start, after the latest Microsoft
  update has been downloaded and installed, it now takes about half an hour to start
  the system of cold starts and 20 minutes from the sleep position.
  It also takes a long extra time to get the Explorer running

  What happened during the update may cause this extra on drag
  performance? How can I change?

  I tried the system restore, but it would allow me to go back only to the point
  When the MS Update has been installed.

  Thank you.

  Is your system error free?

  Event Viewer reports

  1. normally, when an error occurs on your computer looking in Event Viewer should be your starting point to find a solution. More related system errors are recorded and get an exact copy of the relevant report is important. Unfortunately, is not easy to understand reports and most of the users computer need help with their interpretation. I have to say later interpretation.

  2 Event Viewer includes three main newspapers of Windows. Here's the Application, security, and system. For purposes of troubleshooting system is by far the most important.

  3. to access the system log, select Start, Control Panel, administrative tools, Event Viewer, in the list on the left of the window select Windows and the system logs. Place the cursor on the system, right click and select filter current log. Check the front of the error and click OK and see you only reports errors. Click the Date and time column header to sort. You may need to click a second time to see the last report above.

  4. a tip for posting copies of error reports! Run Event Viewer and double-click the error you want to copy. Click the copy button to place a copy in the Clipboard and close Event Viewer. Now start your message and paste it into the body of the message. Make sure that it is the first dough right out of the event viewer.

  5. He cautioned against three types of reports, information, and reports errors. In most situations, it is the error reports that offer the best information but sometimes WARNING reports provide useful clues.

  6. all reports have stamps date and hour and when troubleshooting, it is important to focus on the latest reports. Reports of studies from the point when the computer is started, and then check if a similar report appeared in the previous session. If errors do not repeat investigation as to why they happen is wasted effort.

  7. in the individual reports the most important information is the event ID and Source such as these help when looking for help on the internet. The description is just as important and copy the exact text to use as search criteria greatly helps achieve better results when using Google. Not paraphrase descriptions when other people asking for help.

  Black screen problems are extremely difficult to repair and all hotfix is usually a hit or miss
  base. That there is no information on a black screen as there is just a blue screen
  adds to the difficulty. Often using a restore point or Startup Repair will have no effect.
