Question about HP Compaq dc7100 Ultra-slim PC Desktop

5 Answers

It doesn't start up, only beeps and red light flashes

When trying to power on the red led light at the front of the unit is constantly flashing and will not power on, any ideas?

When I press the button to start up it goes for a couple of seconds then powers off and the red light flashes at the front?

Each flash of the red light comes with a beep from the speaker. It repeats 5 times this sequence (11 seconds each one):
- 9 flashes and beeps (1 per second)
- All flashes and beeps stop for 2 seconds

Then, after 55 seconds (5 times this sequence), the red light flashes 1 per second but there are no more beeps.


I tried looking for the beepcodes in bioscentral but I haven't found anything.


Thanks for all,
LotusWea

    Thanks Myob247,



    I tried to remove all the memory sticks from the system, I have tried to put only one stick in different positions, and I get nothing.



    There is no more cards in the PC. I have check the Riser Card, the extra card to insert the DVD drive and everything is okay.



    I don't know what can be wrong, It was running well two days ago.





    Thanks,

    LotusWea

    For all the people that suffered about this problem.

    I decided to take it out this PC from my wardrobe to fix it, and I found the problem about this sequence of beeps.

    The problem was in the CPU Fan, after placing a new one, not exactly the same fan, because I didn't have one, it booted again as always.

    The CPU Fan wasn't reporting to the Mainboard and this one decided not to boot to avoid possible overheating.

    Have fun again with this PC, now running W/.

    repalce your RAM chip

  • LotusWea Mar 26, 2013

    Remember to check the power cord of the CPU Fan.When I was cleaning the PC I forgot to plug the CPU Fan to the MotherBoard, and the power cord may go unnoticed due to where it is placed.

Try re-seating your memory sticks. Make sure all other cards are secure. Remove them and put them back in if you have to.

RAM is installed in pairs in mine, but be aware the board has 2x2 slots. In mine each pair is 1 black and 1 blue slot. Mine has to have matching RAM in each black slot first. And, yes, it did work loose once and need re-seating. Try that in yours.

I have a broken Dell Precision 470 Workstation. The symptoms are as follows: Won't power up; Flashing yellow power LED on front panel; Blank STR_LED on motherboard; Yellow AUX_PWR LED on motherboa


Flashing front powerlight is often a result of a faulty powersupply, try another powersully on the pc and see if the problem gets solved. I've seen a few of these cases personally.

Computer shut down and red light flashing five times then three second pause and repeats


According to the troubleshooting guide for this model, the red light flashing five times indicates a problem in the RAM (memory), before the video subsystem is ready. You may just need to open the case and make sure the memory sticks are fully locked in their slots. If you just added new memory, it might not match the required specs.

Blank screen and the power LED flashes Red five times, once every second, followed by a two second pause, and the computer beeps five times. (Beeps stop after fifth iteration but LEDs continue flashing.)

Cause Pre-video memory error.

Solution
1.
Reseat DIMMs. Power on the system.

2. Replace DIMMs one at a time to isolate the faulty module.

3. Replace third-party memory with HP memory.
4. Replace the system board.

Hp compaq dc 7100 , my problem is that as i start my pc than 4 beep with time interval 0.2 sec with led than after 0.5 sec it start again , remain continously


Are they Long Beeps? Does the RED led light on the front show up?
If there is no RED led light blinking, then the problem is your RAM.
If there IS a RED led Light showing up, then the problem is your Power Supply.

When trying to power on the red led light at the front of the unit is constantly flashing and will not power on, any ideas?


According to the Compaq Service Reference Manual (http://www.manualshark.org/m/hewlett-packard-hp-compaq-dc7100-convertible-minitower-pc-hp-compaq-dx6100-and-dc7100-series-personal-computer-service-reference-card-28379/) There are several codes listed but not for a steady red LED. Try first unplugging the unit, press and hold the power button for 5 seconds to clear any residual charge in the machine. Then plug it back in, turn the power on and note the error codes. Compare the codes with those of the document link I have posted. Both the keyboard and chassis LED's will display error conditions accompanied by a series of beeps from the units speaker. It sounds as though you have a hardware failure, but until you can verify the error codes with the HP/Compaq service manual, I can't say for sure.

Dell Optiplex GX260 Tower flashing yellow power button


Hi

Power up the Optiplex GX260 and check the QUAD Pack Diagnostics LEDs (located at the back). Compare the LED pattern to http://support.dell.com/support/edocs/systems/opgx260/en/ug/solvprob.htm#1167139 for more info.

Ideally, to troubleshoot and resolve the issues, try removing all PCI devices, disconnect all external devices/peripherals including keyboard and mouse. You may leave the Monitor connected. Power up the PC and check for successful Power On Self Test (POST). If POST completes (generally fails on "Keyboard not present"), shutdown, connect keyboard and try POST again.

If all goes well, install PCI devices one at a time and test successful POST. This will help identity a failing device.
If issue persists, after removing all devices, remove the CMOS battery for about 90 seconds and try POST again. If same, remove all DIMMs (Memory) and check for beep codes. Compare beep pattern to http://support.dell.com/support/edocs/systems/opgx260/en/ug/solvprob.htm#1176760.
NB: Ensure to remove power lead and press power button briefly to use up flea power before working in the system.

If the system beeps, it suggests that the CPU and systemboard are "likely" fine. Install one DIMM at a time and test successful POST. If there no beeps then the systemboard and/or CU is/are at fault.

Regards
Mike

HP Compaq d530


it all depends on the number of flashes , pause, repeat.
Since the problem did not indicate any beeps her is the following info


Power LED blinks RED 2 times, one every second, followed by a
2-second pause. = Processor Thermal Protection Activated


3 blinks 1 second apart = Processor not installed (not an indicator for a bad processor).

4 blinks 1 second apart .= Power Failure (power supply is overloaded)

Other possibilities are:
5 blinks 1 second apart No memory
6 blinks 1 second apart No graphics
7 blinks 1 second apart System board failure (detected prior to video)
8 blinks 1 second apart Invalid ROM
