SOURCE: Dell Optiplex GX260 Tower flashing yellow power button


Power up the Optiplex GX260 and check the QUAD Pack Diagnostics LEDs (located at the back). Compare the LED pattern to 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
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.

SOURCE: Orange light on Dell GX270 power button

I agree, the Optiplex GX270 is infamous for MoBos going bad. The capacitors have a manufacturing flaw, and up until February of 2008, Dell was replacing those boards for customers for free if it was found that the capacitors were the culprit. I just found a board yesterday with this problem. A sign that the capacitors are bad is either a buldge or they will be leaking an orange-rusted looking substance (primarily capacitors near the CPU). Symptoms of this problem include the PC rebooting itself randomly, and/or getting a BIOS error saying there was a thermal event.

SOURCE: Dell 5150c shuts down orange flashing light

As a temporary measure, taking the side panel off the dell 5150c stopped it from shutting down, so in my case it was clearly a heat problem, as suggested by previous the poster. The following instructions assume you're comfortable replacing computer hardware components - do at your own risk!

The solution is to buy an 'air duster' and some thermal compound for the CPU heat sink. If your CPU fan doesn't sound healthy (mine didn't), also buy a new one (ca. £20 on ebay: search for G9474 ).

Read the service manual: for details on how to install / remove the fan and heat sink.

Clean out dust from the heat sink with air duster. Remove the fan, and clean or replace (recommended). Also clean the grill in front of the fan. Clean off old thermal compound from the CPU / heat sink and replace with a thin layer of fresh compound. Replace heat sink and side panel and you're done.

SOURCE: Dell Optiplex 755 does not boot. The steady yellow

I have the same issue, in my case, in some Dell's I get a loud FAN noise as well, so far except for the FAN issue replacing the PSU had no effect so I think it is the MB/Proccessor. Recently dusting out the Processor worked on one of the mis-hap Dells which has thuis issue. I personally think Dell tech's should look into this and post some working base solutions!

My electrolux washing machine displayed E1 error and no water will go in? what to do with this?

Is the pump making a humming sound? If you can answer yes, than it could be just a restriction in the drain line. If you do not hear a humming sound you may have a bad pump or timer. If all of these suggestions pan out and the problem still persists, think about what may have happened prior to this occurrence. For instance, did you notice any error codes, odors, or other strange functions prior to this issue?

Hi there, I've just moved house, I tried to use my MW511 fisher and paykel washing machine. I plugged it in turned it on, it started to work as per usual. A few mins later it stopped. No lights are showing...

Hi Melissa,
Many things could have happened prior to your current problem. You moved house, how was your machine moved? How did you test to prove the wall plug is working? NO LIGHTS mean power is not flowing to your machine. I suggest you consider a proper check and service rather than trying anything on your own, unless someone is willing to provide a full specs on diognastics.

I have a washing machine ASW-A95HT but suddenly it stops working I switched it on but the only thing that's working is the drainage,the buttons are not working the screen not working soon as I...

The standard things to check on all washing machines:
1. check the inlet pipes..if the machine has 2 inlets (hot & cold), both should be connected to pipes.. in your situation, its doubtful that the pipes are not connected, but perhaps it got detached through vibration.
2. ensure that the machine is level, some machines have an auto shutoff safety mechanism which prevents it from working if the machine is not exactly (horizontally) level.
3. If you have just used it for a load prior, perhaps it has overheated.. in this instance, just leave it alone for 20 minutes and it should sort itself out.
Good luck!

Makes clicking noise spin cycle

it may be any part of the balance mechanism under the machine..remember if you did not balance (level) it prior to installing, it has to self level on its own..this usually calls for some noise in the linkages when spinning..

My Keurig B60 stopped working - I plug it in and nothing happens. Prior to this, it was leaking and lights were blinking


The problem is often that the machine develops a leak in the hose that is rightover the transformer...the water drips onto the transformer and kills that...then you have no power to run the machine.

Here is a tip that I wrote about this problem...
