Dell Inspiron M501R (M5010) Beep Codes Diagnostic Indicators

How to identify beep codes:

When a laptop or computer first powers on, it goes through an initial set of diagnostic tests to make sure vital components are preforming correctly. These tests are called POST or Power On Self Test. When a test fails, the user is notified via POST codes, Light codes, or Beep codes. For diagnosing Beep codes you need to:
  • Power on the laptop or restart it if it is already on.
  • Listen to the number of consecutive beeps when the computer begins to boot. Restarting the laptop may be necessary and should not harm the laptop at this time.

  1. Done With Dell

    As so many others have reported, my Dell M5010 operated fine until it began the seven beeps signaling a POST error involving the CPU or motherboard.

    I’ve bought almost a dozen Dell’s in the past.

    Past, here is the operative word. I have bought my last Dell, I’m afraid.

    The performance of the AMD processor was adequate, but nothing more. It’s true that I knew what I was getting (sort of). Still if the processor generates more heat than normal wouldn’t it have made sense for Dell to invest a slight amount of the savings in a better fan; better solder; etc. ?

    When I bought this device I wasn’t bargain shopping, and would have paid more gladly for a unit with an Intel processor (sorry ADM, if Dell’s profiteering is making it hard for you to improve your image; then again, I’m out a computer–so I’m not completely sympathetic.

    I have defended Dell in the past (again you can identify the operative word here easily). Not any more.

    This looks like a classic case of corporate myopia; not being able to see past the next earnings report. Some genius (or gaggle of them, perhaps) has crafted shoddy goods, packaged them with enticing features and a tempting price and let the suckers fork over our hard earned cash. Well I hope it was worth it.

    Other brands have their problems, too. I’m sure there aren’t any “trouble free” computers on this side of nirvana. I’m pretty sure I can find a little more commitment to quality somewhere, though.
