One "beep" is good -- multiple beeps mean something is wrong.

Restart your computer, and be ready to press the PAUSE button on your keyboard, to "freeze" that text on the screen, so that you can read it.

Compaq presario cq61 won't turn on


hi
i wonder if the mainboard has suffered a power failure due to power shortage through electrical system that it was connected to . if the lights do not appear on the media strip below the video panel and above the keyboard, that would indicate a power failure has resulted from the power supply burn out. That being said the mainboard has suffered a electrical sudden power down. Have you tried the AC adapter to ensure it works ? I would need the entire model number and S/N of the notebook to get some feedback from HP

This is a list of ThinkPad Beep codes.
It appears you have a memory or motherboard problem, most likely a RAM problem. Try reseating the RAM modules, if this doesn't work, then remove the RAM and take them to your friendly computer repair shop to get them to test the RAM modules for you. If the RAM is faulty them replace.

Beeping when i turn on and black screen


IT is either one of three things. 
  1. keyboard missing; check it's plugged in.
  2. graphics card; check that it has not been dislodged and is seated properly.
  3. memory. Are the memory cards properly seated?
