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)

Flashing green lightbulb


Do you hear the fans running? Do you hear the hard drive spinning? Did anything ever appear on the monitor?

Remove the Power Cord, Open the Case and remove one of thememory chips. Set the chip aside then try rebooting the computer. If it boots, then you know the memory chip you set aside is bad so mark an x onit with an ink pen. If it fails to boot then move the chip to the nextmemory slot and try rebooting. If it fails take the chip out and set itaside, then put the other chip in and try booting it in both slots. If itboots, just to verify that the chip set aside is bad, mark an x on it and putit into the open memory chip slot and try booting.

Shortly after I turn my computer it turns off


How long is shortly? If it runs and brings up the Windows Desktop and you are allowed to work for 10 minutes or longer then it shuts down, most likely the laptop is overheating. One way to tell if it is overheating is to immediately try to turn it back on after it shuts off. If it will not boot back up, it's overheating. If you let it sit and cool off for a while, then try to boot it back up and it does it successfully, it's overheating.Causes of Overheating:1) Dust all inside the computer. Fans clogged with dust, dust around the vents.2) Fan not working3) The Thermal Past around the CPU has dried up or is too thin the keep the unit cool.When you plug in the power cord is there any lightswhatsoever on the laptop, where the plug goes in or on the AC Adapter of thepower cord?

When you press the power button do you hear fans running, hard drive spinning,lights on the computer, hear any beeps or lights constantly blinking, hear theDvD/CD drive click and the light on the drawer of the DvD/CD turn on for asecond or two? If so the laptop is trying to boot or may have booted, butthe screen is not showing for some reason.

Beep tones and blinking lights tells the technicians what is going on with thelaptop and why it is not booting. Most times it's a motherboard issuewhen you hear beeps or blinking lights continuous.

The power at the start is red and not green how can i know what is the problem is it the power supply or others please answer me.....


Power LED flashes Red,
once every two seconds.
OR
Power LED flashes Red four
times, once every second,
followed by a two second
pause.

Would this be the symptom?

If so, then yes, the Power Supply is bad.

What causes this?

1) A large percentage is due directly to the fact, that the computer is dirty inside, as well as the inside of the Power Supply.

2) A smaller percentage is that the Power Supply is a low quality unit, installed by the computer manufacturer.

Computer unplugged from power, computer case open, anti-Static precautions observed.

Using a can of compressed air for computers on a regular basis as needed, would help prevent Power Supply failure.

Is the dc5000 the Small Form Factor, or the Micro-Tower, style?
(SFF style looks like a Pizza Box)

Will look up Power Supply replacement for you if you wish, and information on replacing it.

Hinges too tight on laptop


This is the exact opposite problem many laptop owners face. There are a few causes, and a few soloutions.

  1. Remove the covers from the hinges and put a small drop of sewing machine oil into where the 2 hinges meet. Open and close the lid a few times to massage it in.
  2. One of the hinges could be slightly bent. The oil method above will help that aswell until it wears into it's new position.
Try that and see how you go. Do not use CRC or any spray lubricants if you can avoid it. There is a huge chance of some of the spray going inside the laptop.

Problems with My Monitor Screen.


Hi,
Sony vaios are very tempramental.
Did you drop or bang the machine, before this happened ?
There are a few suggestions.
1:) the screen catch mechanism is jammed.
Solution:- turn on laptop, using a small blunt screwdriver. where the laptop latch, goes into the laptop base. gently push the latch mechanism a few times, to see if it,s jamming.
2:) if the screen display shut off mechanism is under the actual laptop screen lid, push the small plunger, up down several times.
These are common likely causes.
3:) press and hold the power on button for 15-30 seconds, this is in case the system has gone into hibernate/sleep mode.
4:) ensure The battery is fully charged. And the laptop power supply is plugged in.
If none of the above work for you, you may need to take into a repair specialist.

Mike @ compurepair.
