Wont post led 3 flashes


if its the red flashing light on the tower, its the hard drive activity light.

when the monitor goes on stand by, does the tower retain power? (green light on and flashing red light sometimes?) Does your keyboard's scroll lock/num lock/caps lock keys and keyboard lights work?

Dimension 8400 will not boot and more.......


I would recommend testing the power supply as Dell PS's are not known to be "forever". A power supply tester can be purchased online at Tigerdirect.com for around $20 and they are fairly easy to use (you can also get a new PS there if necessary). If that is not it, I recommend going to a local small computer shop and picking up a used Hard Drive (be sure to get SATA), and switch it for your main HDD,, if the PC starts up and goes to an "Error no OS found" or the ilk, the culprit is your hard drive. I am in CT and fix PC's for a living, I am A+ certified and have passed all the dell Factory Cert tests. If you need help and are in the area or work well over the phone,, let me know I CAN solve this problem.

Maintenance light flashing


h) Engine Oil Replacement Reminder
Light (for vehicles sold in U.S.A.)
This light reminds you when to replace
the engine oil.
This light will come on when the ignition
key is turned to “ON” and will go off after
about a few seconds.
When you drive for about 8000 km (5000
miles) after the engine oil replacement,
this light illuminates for about 3 seconds
and then flashes for about 12 seconds
with the ignition key turned to “ON” position.
If you continue driving without the
engine oil replacement, and if the driving
range exceeds 12000 km (7500 miles), the
light will come on after the ignition key is
turned to “ON” position. The light will remain
on thereafter.
If the light is flashing, we recommend that
you replace the engine oil at an early
opportunity depending on the driving and
road condition. If the light comes on, replace
it as soon as possible.
You need to reset the light after the engine
oil replacement. Reset the light by
following the procedure below:
1. Turn the ignition key to the “OFF” position
with the odometer reading shown.
(For details, see “Odometer and two
trip meters” on page 136 in this Section.)
2. Turn the ignition key to the “ON” position
while holding down the trip meter
reset button.
Hold down the button until the light goes
off. Before the light goes off, it illuminates
for 3 seconds, flashes for 2 seconds and
illuminates for 1 second.
If the system fails to reset, the light will
remain flashing.

LaCie 250Gb drive does not power up


It's the power supply connection in the HD case has failed. Try the HD in another case (if you have one handy) to check whether this is the problem. If so, find a replacement case.

3 Red Lights Flashing - is a general hardware failure
  • Unplug everything and let it sit for 20 min. Re-connect and try re-starting
  • If these steps do not resolve the behavior, turn the console off, remove the hard drive, and then turn on the console. If the 3x Red LED error light is no longer displayed, turn the console off, re-attach the hard drive, and then turn on the console.
  • Check the lights on the power supply. When you turn on the console, the power supply light should illuminate green even if the three lights on the console flash red.
