    when i go to power up the red light immediately comes on and stays solid. It sounds as if the tower is loading a disc. When i turn the moniter on it comes up with the acer screen and then goes black and the shuts off automatically. What could i knowing very little, just the basics, do to get this computer booted up. please be descriptive if possible?

How I solve this issue of a customer of mine.
replaced power supply and one memory stick was faulty
lesson learned: check the obvious first.. .Powersupply.. if problems persists... check your ram... if you have 2 sticks of ram,, try reseating and using one at a time or swap with known good memory.

I have this same problem with a pc my brother gave me. My Pc just shuts down in the middle of games and then the red light flashes and I am not able to start it.

However, I have found that if I just unplug the power cord from the power supply for a min or less, it turns right on again.

Hope this works for you. Saves you trouble of going inside the case.

Power supply may need to be replaced but this is too much of an intermittent issue to replace in my opinion.

This will require a bit of troubleshooting. It could be the power supply is faulty, in which case you should try testing your machine with a different power supply to see if it will boot. It could also be the motherboard. Also, it's possible it could be either the CPU is bad or that the fan isn't properly seating on the cpu or that you simply need to reapply some thermal compound on the cpu. If you don't have any extra parts to do some tests, see if you can get a friend to lend parts or have a tech-savvy friend help you out.

Unplug the power from your computer and crack the case. Unplug the power supply from the board. Then plug it back up and try it again sometimes this resets it and it will start again. But it didn't happen by chance there was a reason and something is going out in your computer. Itcan be alot of different things. Pull them out one by one and you may be able to aliminate the problem. When you find the bad part replace it with a new one and your up and running again.

The following article gives an extensive look at trouble shooting power supply issues on HP & Compaq PCs. I was going on the assumption that this was the light you were referring to. Give them a shot. http://h10025.www1.hp.com/ewfrf/wc/document?lc=en&cc=us&dlc=en&product=376064&lang=en&docname=bph06788 Compaq Presario 5000 is quite an extensive line, and contains both laptops and PCs. I hope PC was what you were looking for.

Here's another thing that as far out as sounds, works for me. Take a hair dryer and turn it on blowing the air on back of tower where the fan is. In a minute or so. Light turns solid and will power up. Works for me anyways.

Posted on Dec 10, 2014

Thanks for everyone who answered my query.
Fortunately I have fixed the problem and am using the machine day and night (“self employed”) now.
On one hand, I did reach a point that the power supply light flashing eventually stops if I unplug the last main mother board cable. Then I plug in the cable, very carefully, the flashing was not starting (a good sign for me).
On the other hand, I have thoroughly checked all the connections and contacts, reaffirmed them. I also found one small cable which was not connecting correctly (did not know why there was no problem).
After these two “methods”, the machine suddenly started working as usual . I assume the machine now should withstand a power turn-off but I do not dare to do that yet.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
One another occasion, my daughter’s Sony notebook suddenly stopped working one day (does not power on). I also tried my best – searching for service manuals and opened the machine up and confirmed the switch is good but failed to go any further (no service manual and also I am not that good). While I was making my mind up to repair the machine (it costs about 1/3 of a new notebook’s price). One day, I just got this idea I need to smash the notebook (suppose it is a contact problem). So I simply hit the machine with my palm, solidly but in sort of control, on two sides. And then suddenly, the power-on starts working again. Really amazing! It has been working for quite a few months now.

I had the same problem on my HP t350.uk machine but with different symptom.

It first appeared one year ago when my daughter switched off the machine (everything was fine up to this point) at night. The next day, the machine could not be started but she noticed the machine's power supply light was flashing. It was in this state for a few hours as she does not know what to do. Then suddenly the flashing stopped and machine can be started and everything returned to normal.

Then about half a year ago, I turned off the machine to add some memory (from 512mb to 1.5gb) and could not start the machine while the power supply light was flashing. My daughter told me the trick but it did not work after a few hours. So I left the machine connected to power over night. Next morning, the flashing was gone and everything returned to normal.

 

But later on, the machine occasionally ran into a freezing state, not responding to any input.  So a few days ago, I turned off the machine, and did some connection checking on the motherboard. But this time, the flashing never stops flashing, even after I have unplugged almost everything.

 

The flashing stops only after I unplug the power to the motherboard. By manipulating this power cable to the motherboard, I can manage to turn the flashing to the constant flashing, but the machine still can’t be turned on.

 

I was just wondering this event sequence would inspire any useful trouble shooting thoughts

Remove the battery from the motherboard to reset your bios let it stay out 60 second and then put it back in

All you have to do is check all your connection from your main power plug to motherboard.Plz check your AC voltage in your area.Then unplug your power cord from power supply(SMPS) and resit your ram. If the problem still there then change your powersupply.Let me know if the problem still persists

Probably better check the power rating it could be 220v and you accidentally plug it to a 110v outlet.

SOURCE: red light flashing on power button

Sounds like the hard drive has had a failure, you need to get a replacement one, and reinstall it, along with the opperating system, and any other programs that were on the old one.

WHY DOES A RED LIGHT FLASH 4 TIMES THEN SHUTS OFF ON MY HP COMPAQ


Hi:
Here is what I would do...
Turn the PC off and unplug it. Then press the power button to drain any residual power from the motherboard.
1. Remove and reseat the memory module(s). Restart the PC.
2. If removing and reseating the memory module(s) doesn't work, if you have more than one memory module installed, remove all but one, and start the PC.
Test each memory module one at a time, until you find the one that is bad.
If none of that works, check for bulging and leaking capacitors on the motherboard. These may be particularly noticeable around the processor area.

Press start button, fan trys to start, green light comes on then changes to a red flashing light


If your fan is trying to start up but won't, your system is going to give you a warning and most likely shut down. Make sure you have good connection for fan power and that it is clean and can turn freely. You may want to cosider replacing the fan.

Hello have a problem with tv Model is: lg


http://lgknowledgebase.com/kb/index.php?View=entry&EntryID=6281

The above link goes to lg's website describing the red flashing light where the power switch is, and

another switch down below which can turn that light off.

Try switching that other switch below off so the light turns off. Then, switch it back on.

If that doesn't work, then service should be scheduled for this discontinued model.

Hope this helps on your lg tv.

hi,
The machine is getting the power but no display.This seems a RAM or motherboard issue.
1.Press and release NUM Lock after turning on and if it is responding this is a RAM issue and if not then the mainboard issue but before all refix the RAM once.
Thank You.

I Have A Compaq Presario That Will Not Power Up.


It sounds like your power supply unit as some leaky components, normally the bad powersupply unit show these types of symptoms. Try borrowing a powersupply unit from a friend that is similar to yours and replace to check if the powersupply unit is the culprit. If cornfirm PSU, than you neet to get yours fixed.
