Entries might include major hardware or software changes, driver updates, minor issues you have experienced and how you resolved them. 12. If you ever need to run a recovery on your computer to return the preload onto the machine, the following tips might help along the way: • Remove all external devices such as the printer, keyboard, etc. • Make sure that your battery is charged and that you have the ac power connected. • Boot into the ThinkPad Setup and load the default settings. • Restart the machine and start the recovery. • If your machine uses discs as the recovery media, DO NOT remove the disc from the drive until prompted to do so. 13. For suspected hard disk drive issues, refer to "Diagnosing problems" on page 181 and run diagnostic test of the drive prior to calling the Customer Support Center. If your computer does not start up, download the files to create a bootable self-test media from the following Web site at http://www.lenovo.com/hddtest. Run the test and record any messages or error codes. If the test returns any failing error codes or messages, call the Customer Support Center with the codes or messages and the computer in front of you. A technician will assist you further. © Copyright Lenovo 2012 175
