Searching for other possible solutions

If a solution is not found by using the information or articles linked above, use the following tips to effectively search the BlackBerry Knowledge Base for a solution:

  1. Use the customer's words.
    • For example, BlackBerry will not turn on instead of The device will not boot or startup.
  2. Use keywords and be straight to the point (avoid filler).
    • For example, When the BlackBerry has been turned off it will not turn on
  3. Use quotes to search for an exact set of words.
    • For example, Application net_rim_bb_vvm is not responding finds many articles, but "Application net_rim_bb_vvm is not responding" finds only the article with the exact error.
  4. Refine search results by entering another search in the Search Within search box or by selecting the applicable product from the Focus Your Results section in the left sidebar.
