    Both. We managed to open the laptop and found the south bridge was getting rather warm in the short time the power is ON.

    The Fan stops after a few seconds. The the AC adaptor the Power LED is still ON. Nothing else works.

Hi babbra,

Does this happen with the ac power or on battery power or both?

    Hi Babbra,

    If I understand you correctly, the Processor is getting warm immediately after the power is turned on and the fan stops after a few seconds. Sounds like the fan needs replacing. What is happening and why it's happening is because of a heat saftey feature built in to the motherboard. Once the laptop is powered up and the fan stops the heat temp is recognized in the bios as being too hot so the system will not boot.



    Replace the fan and let me know how it turns out.

Acer power 1000 will not turn on


Whenyou plug in the power cord is there any lights whatsoever on the laptop, wherethe plug goes in or on the AC Adapter of the power 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 computer is trying to boot or may have booted,but the 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. Most times the problemis with the memory or Video Card. Count the Blinking Lights or Beeps and takenote of their pattern (1 Long or 1 Long followed by 2 Short).

Maybe you have a Static ChargeBuildup. Remove the Power Cord, then Press and Hold the power button for30 seconds. After 30 seconds plug the power cord back in and hit thepower button to see if it boots.

Maybeyour memory is bad or the memory slot is bad.Removethe Power Cord, Open the Case and remove one of the memory chips. Set thechip aside then try rebooting the computer. If it boots, then you knowthe memory chip you set aside is bad so mark an x on it with an ink pen. If it fails to boot then move the chip to the next memory slot and tryrebooting. If it fails take the chip out and set it aside, then put theother chip in and try booting it in both slots. If it boots, just toverify that the chip set aside is bad, mark an x on it and put it into the openmemory chip slot and try booting.

Maybe your power cord is bad if you don't get anything to happen whatsoeverwhen you press the power button. And if that's true maybe you wasoperating off the battery the last time you had it on and since the power cordis bad, it was not charging the battery so the battery is drained and the powercord is bad.

Maybe you have a Static Charge Buildup. Remove the Power Cord, Remove theBattery, then Press and Hold the power button for 30seconds. After 30 seconds plug the power cord back in (leave the batteryout) and hit the power button to see if it boots. If it does, you can putthe battery back in and let it charge.Maybe your DC Power Jack which is where the power cord plugsinto the computer is bad. Take an ink pen and push the tip inside thejack and see if the little pin wiggles, if so the jack is bad. You'll have totake the laptop apart to fix it. Most times it is soldered onto themotherboard, so you will have to desolder the old and solder a new one.Maybe your memory is bad or the memory slot is bad.Remove the Power Cord, Open the Case and remove one of thememory chips.

Acer x3400 wont start up


Remove the Power Cord and then press and hold the power button for 30 seconds. After 30 seconds plug the power cord back in and press the power button. If it reboots you had a Static Charge Buildup and released it by holding the power button for 30 seconds.

When you press the power button do you hear the fan running, disk drives running, cd drive clicks once, anything on the lcd screen? If not I would think your Power Supply is bad and needs to be replaced.

It's either the Power Supply or Motherboard.

What causes red led on starting?


Remove Power Cord then press and hold the power button for 30 seconds, then put the cord back in and try to start it.

When you press the Power Button are you hearing the fans run, the disk drive running, the cd drive click and the light on it comes on for a second or two?

Anything shows up on the LCD Screen?

If you press the power button and absolutely nothing is happening then you most likely have a bad power supply.

If you press the power button and you start hearing beep sounds or blinking lights in a continuous pattern (ex. 1 long followed by 2 short) then you have a motherboard issue. Those beep sounds and blinking lights tells the technician what is going on with the computer.

Problem with Sony Vaio pcv-rx860 (screen goes black at startup)


I would suggest first to try to take one stick of memory out and try to boot up the pc. Sometimes, one or both of the memory sticks can go bad or the memory slot on the motherboard itself can go bad. If that is not the case I would then remove all of the usb connected to the computer and last i would test the power supply.
