1 - Check the battery contact and make sure the batteries in the flash are good.
2 - check the plug for the turbo, make sure it is not damaged, as well as, the high voltage plug on the 580 flash. If those contacts look dirty or mushroom shaped, you will nee the flash repaired.
3 - obviously make sure the turbo is charged

Just had the same problem.

I think the battery compartment door moves the batteries upon closing so that a good contact is lost.

I am using fresh alkaline AA's
I tested each battery & they are 100% charged at 1.5v.

I tried several times but nothing on the display.

Heres how I fixed it...
I connected the speedlite onto the shoe of my camera body.
Then inserted the batteries whilst the camera & speedlite in upright position. This seems to put some gravity on the batteries, whilst closing the battery door attempts to defy gravity.

Hey Presto - It's now working fine.

Laptop wont boot up


Stay away from Emachines in the future. Pay another $100 and get a real computer.
1. check that nothing is in the CD-Rom drive and restart the computer.
2.Shut down the computer. Unplug the AC power. Remove the battery pack. Wait 2 minutes or until machine cools.
try powering on comp on battery alone, then try with AC power alone.

My toshiba 2455-s305 wont boot up


If you are familiar with your laptop, i.e. the locations of hard drive, try to take it out of the its bay and put it back again. Also, if you can have someone check your battery packs, because from my experience with this laptop, when the battery packs is not charging well, i got some booting up problems.

My toshiba laptop l10 281 has stopped working it was working perfectly and was shut down properly wen i went to turn it on again today it wont go it wont even light up please help!! thanks in advance john


If nothing at all works then perhaps you have no power to the system.

Check that the powerpack is getting power (does it hum or get warm when plugged into the mains socket?) Check all connections to the power pack and back of laptop.

Try taking the battery out and powering up on only the power pack

Do you know anyone with a similar laptop that you could swap power pack with?
