Power supply question - amber LED flashing - Dimension E520

So, I'm working on the dust removal and re - install windows on a machine. I've done dusting, but now I have problems with a LED flashes orange. The system will not top all - fuel without fans or beeps.

After looking through some posts for ideas, I think it is a bad power supply or a problem with the heat sink.

I think power because this seems to be a common problem. How can I test the existing? Is there a way to fire unless it is connected to the motherboard?

The reason why I am wary of the heatsink is that I removed it when I was doing the dusting. I had the intention of fire tonight and get a new thermal paste in the coming days. Since then, I have read that this could be a recipe for frying the total CPU and I wonder if the machine is not pulled up like a check for free preservation any.

It detects if I removed the heatsink? If it's happening, it will automatically detect when the new thermal paste is in there? Or is there a reset procedure any?

Any help would be great. Thank you!

As a side note, the design of this box is poor. I can't find some way to dust effectively the heatsink without removing it from the central unit. Supply openings do not match, so you cannot blow a good flow of air through the box.

A flashing orange switch LED means that the computer is under voltage, but a power problem internal may exist.

This may indicate a bad diet

Are the Diagnostic LEDs on the front panel lite?

Have you checked that all the cables to the motherboard and the disks are properly connected, by disconnecting and then reconnecting them?

  • HP ENVY PHOENIX CTO 810-135QE - 600 watts power supply Question

    In the near future, I would like to upgrade the video card in my desktop HP ENVY PHOENIX CTO 135QE-810 GT 640 default to something a little more powerful and I was wondering if there is any details about the default 600 watts power that will help me in my decision to the next video card.

    I know that some video cards require a number of amps on the 12 volt rail and all the information that I have found previously on the power of 600 watts power supply in the computer is not in that kind of detail.

    What I read, the power is a Petrus 600W e-star 5.0 Bronze, HP Part number 633186-002.

    Any additional details and details on this power to help me determine the next video card would be useful.

    On a side note the video card, I'm currently doing is one of the next Nvidia GTX 750 TI models, thoughts and recommendations on this specific map?

    Thank you

    Hello

    Your PC has UEFI bios, so most video cards should work.  Some video cards will work in UEFI mode and others in legacy mode, that your PC is able to run.

    When the manufacturer of the video card and/or AMD or NVIDIA specify a minimum power supply size then it is best to stick to this recommendation.  Not all power supplies are built to the same standards of quality.  In addition the internal components, temperature, charges unknown and time that the PC will be placed under the maximum load are taken into account at the recommendation of minimum power supply is indicated.

    I have not seen a power of 500 watts with 12v rating of 18A, but this does not mean that there is not. And if that's the case, then the total power rating is suspect. A video card that requires an external auxiliary power connector will also draw power from the PCI-E slot.

    Are there cases where the minimum size of the power supply is insufficient? Yes, those who might be extreme but someone can have connected to power different connectors either to avoid buying a new power supply or maybe around just the food manufacturer minimum power rating. Some may do it thinking 'I'm going on fox the Fox ". It can work, but maybe the questions later start occurred.  I prefer to get the job done right the first time. You don't need a power supply to perhaps of overload and short circuit then internally causing spikes to the components in the PC.

  • Reference Dell GX620 Power Supply Question

    What's up guys, I'm new here, and earlier this month my school made me a job on time partial like the public library IT Assistant, because I took IT out classes at my high school. I'm 18, and I know a little about computers. My question is, one of our computers at the library, a GX620, the power supply of the machine went wrong and that we have at the back of the library are detached power supplies for GX520, I asked my professor of computer SCIENCE at the school if it would be prudent to go and try to install the GX520 power in the GX620, but I'm still not sure if it will be a sure idea It would cause a fire? He would burn something inside the PC? My COMPUTER teacher told me to check the amps and volts on feeding 620, and I checked, the GX620 power supply has a maximum of 275 WATTS, while feeding GX520 has a maximum of 220 WATTS, is completely switch the GX620 bad diet, with the GX520 spare?

    And you know that the PSU is bad, how... ?

    First, you will need to know if the spare GX520 PSU's for the same (Tower, Desktop, small, ultra compact) form factor as the GX620 before you can even think to use it because if the form factor of the PC is different, it cannot even between.

    There is a block of POWER W 220 here that says: it adapts GX520 both GX620 Desktop. But if you do not have a GX620 Desktop, this power supply may be a bit low power if the original was 275W.

    That said, you can get a power supply for the GX620 here for less than $30, depending on the form factor. If your existing GX620 power SUPPLY PSU 275W, it seems you might have a small GX620 form, based on the specs of the PSU indicated on this page.

    BTW: Please delete the telephone number of your post. This is a violation of the terms of the forum to use to post personal information, not to mention that it is never a good idea to post personal information in any open forum.

  • Can power supply Question - I use the 230W power supply with a W540?

    I have a W540, which currently uses a power 170W (8.5 a 20V)

    I got also a docking station for a P50 that has a power of 230W showing 20V 11. 5a.

    The connectors are similar, but I'm hesitant to try the 230W power supply in the W540.

    It is allowed to use the 230W power supply with the W540?

    230 watts is maximum power feeding, it only provides the energy required by the computer.

    I sold my W540, so I can't test it for you. But I do use the ThinkPad X 1 carbon with 230 watts without no problem power adapter.

The minimum recommended power supply 400W (according to the Nvidia site) but in my x 51 power supply is 330W. This will potentially cause problems? Thanks for the clarification.

    I got my x 51 beginning 2012; refurbished.

    Don't worry about this. It is very good. You have a beautiful piece of engineering.

    The X 51 has a laptop computer power supply. Crazy or genius?

  • Photosmart C309a does not illuminate and its power adapter 0957-2259 LED flashes.

    I have a Photosmart all-in-in-one C309a.  A few days ago I started to receive messages from the ink system dailure, with the 0xc19a003e code.  I followed it to corresponding to a unit of printhead failed, so I ordered a replacement parts HP UK store on Friday, October 14, and it came today, Monday the 17th. Great rotation of the order of HP UK - thank you.

    When I came to adapt to the new print head today, the printer does not illuminate.  No sign of the power of the power button, the buttons command or display.  The power adapter (model number 0957-2259) has a green LED which was (and still is) very quickly - flashing several times per second.  After that the power had been in the power adapter for a while (several tens of minutes I think, I wasn't timing it) noise started coming from the inside of the printer.  It is a kind of regular knocking and seems to echo the led blinks - but there was still no sign of power - including no movement of the ink/printhead assembly.

    I tried to find suggestions online and I've seen a few posts on some websites that suggest that the adapter can be unloaded in some way - but they are almost exclusively on the PC.  Posts read as if there is some kind of capacitor which accumulates (too) charge and discharge it restores the adapter to the operating state.

    I just reconnected the power again to see if there is no change.  After about 10 minutes, hit him coming back for a few moments then stopped.  I noticed that the LED on the AC Adpater was green fixed so I tried the power switch on the printer and it began to start.  But then hit him came back, the display panel started flashing white light and then complete disappearance of signs of life (other than sound knocking, which became intermittent, maybe 5-15 seconds each time).  The LEDs returned to.

    And then after maybe 20-30 minutes with the power, the printer finally tried to start, the light of the AC adapter / CC has been stable and my computer thought that the printer was (briefly) online.

    But the adapter light started blinking and now the printer behaves as if it has no power.

    It seems to me that the symptoms is due to a problem with the AC adapter.  Then

    (A) that seems reasonable?

    (B) is there a way to release or otherwise 'fixing' the adapter?

    or (C) is it better/more safe to replace the adapter?

    TIA,

    Chris

    The adapter can be reset as described here.

  • Power supply question

    Hello

    I have an old y580 and love it! I've been running it since its release date. Unfortunately, my diet started to wear off and the cord pulled out of the unity of the adapter. Needless to say that Lenovo does not sell these power units and the liteon and delta recommend supistutes sells... in my research online, I came across "y580 feeds" but I noticed that they to 19 v not 19.5 and 6.3 No 6.15.

    I was wondering if anyone has experience with this and knows if it of a big problem or will do the trick without limiting performance or damagaging my y580. Thank you!

    It shouldn't with this difference.5. The laptop works at the voltage of the battery. The current capacity is larger and its fine. Polarity and the connector must be the correct type!

  • HP Pavilion m9066 green led flashes

    I have HP Pavilion m6099 and nothing happens when I press on at the power switch. At the back of the power supply the Green led flashes when the power cord is connected. When I take off the motherboad main supply cable stops flashing and led a continuous green light. When I connect MB power cable flashes again begins.

    Can I determine this behavior that PSU is ok and the problem is in the MB, CPU, memory, etc. I tried to remove all of the cards memory one by one, but still flashing continues. I have no tools to test the PSU.

  • The amber light flashes on my Satellite L755

    Hello Mr President

    I have the Toshiba Satellite laptop L755 came from Finland in 2011. I use last 4 years now and it worked fine, but since there is a few months on and the charging light started to blink a few times it s late start or sometimes sound immediately.

    Yesterday I changed the battery and the AC adapter / CC, but the problem persists. I reset the phone by removing the battery and the AC adapter / CC, hold the power for butt 30 sec button, nothing happened.

    Hello

    On this virtual path, it is not easy to say what the problem is here. If you are not able to boot up your laptop and everything that happens is a light flashing, I fear that there is a problem of electronic power supply.

    A flashing sends a code. This code can be read by technicians and by using this code, they can find what is the problem. If there is a serious problem with electronic board I assume service say that the motherboard must be replaced and it is quite expensive.
