Perhaps some connected devices, turning on with little delay, and using (in a flash) power from the central unit.

it happens less frequently when windows is almost loaded, ( after the windows colored logo disapear or as it disapears)

I have a 1994 plymouth voyage se and it will not strat. It tell me to check gauge light comes on. what should i do or what does that mean?


Turn key to on ( not start) then off, then on, then off, then on and leave on, and have a pen and paper ready to record flashes of "check engine light". It will flash then pause between second number of 2 digit code. Then a short pause and flash again, pause, then flash. For example: if it flashes 2 times, then pause, then flashes 2 more times, that would be code 22. If it flashes 3 times, pause, then flashes 5 more times, that would be code 35. As I said, there will be a short pause between 2 digits, as well as after number. Write them down as they come up and get back to us with those codes for advice. When you get code 55 ( 5 flashes, pause 5 more ) that means end of message. Those codes should point everyone in right direction of trouble spot.

I have an intermittent power-on issue with my Dell E4200. Sometimes it is very hard to turn on - pressing the power button makes the button light up, the fan runs for a few seconds, then the caps lock icon...


Try performing a hard reset on the laptop. Remove the battery and all peripherals connected to the laptop (including the AC adapter). Once everything is removed/disconnected, press and hold the power button for around 15 seconds. This will drain all remaining charge in the motherboards capacitors which usually causes this kind of issue.

Hope this help. Goodluck!

I replaced the main board in my sony Kdl-32S300. When turn on power, the back light flashes 3 times then goes into standby mode after which the standby light flashes 12 times in sequence. What could be...


B+ over voltage protection (OVP), unit goes to the standby mode then displays the 3 blink fault. This is also a problem in the power supply circuit, check T603 and R672.
Have you set the output voltage correctly?

Compaq nx6110 PC Laptops: When i turn it on the lights flashes then goes off...


Which light flashes? If it is the battery light then perhaps your battery is empty?
When plugged into your PSU does the power light turn on? If not your PSU may have broken or the plugs fuse may have blown.
Other potential causes could be your RAM, CPU or even your system board. Check the RAM is correctly seated, if two modules are installed try removing one.
Hope this helps, www.PuterCare.com

On older Sony, sometimes a power surge causes the set to be in shut down mode. Try unplugging for 5 minutes and then plug in and try. This many times will fix.
