HP Desktop PCs - Computer Does Not Start and Emits an LED or Beep Code What to do when beep codes occur Beep and LED code descriptions Testing computer memory for troubleshooting Finding repair service This document pertains to HP and Compaq Desktop computers. If your computer makes one or two short beeps before starting, this is normal and your computer is telling you that BIOS startup was successful. If your computer beeps and does not start, a more serious hardware issue is likely occurring. This support document contains information that can help you learn more about the issue and how to resolve the problem. What to do when beep codes occur An LED or beep code usually means a basic function was unable to start. A basic function might be reading memory, displaying video, or being able to send information to a hard drive. The most common problems that cause LED and beep codes are memory and he
lunar landing. I and my good friend Don Eyles were two of the 'young experts' at the MIT Instrumentation Lab - Draper Lab - who worked on the software for the LEM guidance computer. Graduated from MIT the same year you graduated from CalTech https://www.hq.nasa.gov/alsj/a11/a11.1201-pa.html (1966), and Don is a year or two older. I joined the Lab in January 1967, and Don had been there for about six months. Because the more experienced people at the lab were concentrating on getting the Command Module Computer software right, the two kids were given the responsibility for programming the LM powered-flight routines. Don was responsible for the LM P60's (Lunar Descent), while I was responsible for the LM P40's (which were) all other LM powered flight except beep codes for P12, which was the Lunar Ascent program; we didn't concentrate on getting up from the Moon until a little later. You may have come across the tag "BURNBABY" in connection with the LM powered flight software. That was us. We might not have been out on the streets, but we did listen to the news, and the two biggest news stories were Viet Nam and Black Power, the latter including H. Rap Brown and his exhortations to 'Burn Baby, Burn' -- computer beep codes this was 1967, after all. You have to constantly keep in mind the amazing - to anyone using a PC today - constraints we had to work with in programming the LGC. There were 36,864 15-bit words of what we called "Fixed" memory, which today would be called ROM, and 2048 words of "Erasable" memory or RAM. With only rare exceptions, all of the executable code was in the Fixed memory, along with constants and other similar data. Erasable memory was used for variable data, counters, and the like. With so little Erasable memory available, we were forced to use the same memory address for different purposes at different times. Thus, a location whose contents might be altitude-over-the-lunar-surface during the landing stage might have contained the results of a sextant sighting of a navigational star from the alignment program. I think there were some memory locations that were shared seven ways. You can imagine the testing we had to do to ensure that the same memory location was not being used by more than one program at the same time. The only time that programs were executed out of erasable was when we had to "patch" the program after it had been released and the fixed memory configuration had been manufactured. The most famous incident was on Apollo 14, when Don figured out how to patch the program to ignore the faulty Abort switch. This patch was radioed up and the crew entere
