Honor 9 Lite review
i have a friend who's desktop is completely dead. his son told him it made a funny noise then switched off & now there is nothing
i have tried a different power supply in & nothing.
is there any way to bypass the on/off button on the front of the tower to check to see if thats the problem.
also if anyone has any suggestions as to what the problem might be i would be grateful
no lights, no fans nothing
completely dead as a dodo
infact a dodo has more life in it!
If trying a new PSU didn't work, it could be the motherboard needs replacing.
"is there any way to bypass the on/off button on the front of the tower to check to see if thats the problem"
If you can open the box (main switch off at wall)
Trace the wires from the front panel to the motherboard. Pull off this 2 wire connector at the motherboard.
Now switch on at the wall again and momentarily short just the 2 pins which you have exposed, using say a suitably shaped screwdriver. (If nervous about the shaft contacting something else as well you can mask the sides of the s/driver temporarily with sticky tape)
It is a low voltage circuit which is "made" when the switch is depressed and normally locks the PSU on until toggled by another press.
If the computer boots up as normally, then it is a faulty switch, but these seldom give any bother in a very long life, and I'm not hopeful.
that is a possibility but i wanted to rule out the power button before going for a new motherboard but i don't know how to bypass the power button
i must learn to type faster
i will try that & let you know
"Now switch on at the wall again and momentarily short just the 2 pins which you have exposed, using say a suitably shaped screwdriver."
I have a peculiar shaped jumper with a long tag on it that I use just for this purpose. It's a useful tip - common sense tips from you as usual. :-)
There are a number of things that can cause a PC to be "dead" - graphics cards, memory modules and a number of other things. Now this is where you start tearing you hair out - 'cos it's a process of elimination. :-) - Why not try this?
1) Remove all cards from the expansion slots - you should get an error beep when the graphics card is removed - the others don't really matter for now. If you get an error beep, try with just the graphics card on its own.
2) Try a new memory module on its own.
3) Try a new graphics card - doesn't have to be "new" but any known working graphics card.
If there are signs of "life" from the computer, doing one of the above - it could possibly one of the cards causing the problem. I had a sound card that "killed" my computer - but once removed, like Lazerus, it returned from the dead. :-)
If none of the above work - you could check you CPU, by removing it and checking the underneath for "scorch" marks - if none, reseat it with sufficient gel between that and the heatsink.
Hope you get it fixed! I've just got out of "you-know-where" after being reduced to a gibbering idiot with one PC - so the best of British! :-)
thanks for the advice i will try that tomorrow
will let you know how it goes
it is possible it might be the fuse in the plug lead...simple to try first!!!
that was the first thing i checked
i even used a different lead & checked that on another pc just to be sure
