[VIA] KM4M-V: When powered on, Power LED not lit

Hi, I have a problem with my KM4M-V... I bought this mainboard after my previous mainboard couldn't work, but after buying, it doesn't solve the problem. When I switched on my PC, my HDD LED is lit, but my Power LED is not. I changed a new Power Supply but it doesn't work too. Can anyone tell me what is the problem? Thank you!

Suggest you press button above then Forum Profile Information and create a signature like mine; it will saves us a lot of time and effort. It will take you a few minutes but advice will be more specific and productive. Notice information we need for psu, both of those you have tried.
Did your old motherboard ever work or did it just die on you without warning? If both boards display same symptoms than your problem most likely rests with one( or more) other components.
For troubleshooting take motherboard out of case and barebone it, i.e cpu/hs, vga, 1 stick of memory; you can jumper power switch pins with screwdriver to fire it up. Simply a case of replacing components until culprit is found.

HP Photosmart C310 Series Printer Display and power LED not lit...still able to print.

I am not sure what happened. I was printing, walked upstairs, came back down and the display and power LED on my Photosmart C310 were off. I thought the circuit for the outlet had tripped but that was not the case. I unplugged the printer, disconnected the power supply and let it sit for 2 minutes. Plugged it back in and nothing changed. Forced off printer/reboot?..nothing changed. Tried online utility. Useless. Is this common? Is there a solution? Any suggestions? Thanks in advance.
Have had problems with HP and Compaq in past and obviously made a mistake buying again. Product is past warranty and I am not willing to pay to speak with a "representative" who is on a computer using a diagnostic tree program literally taking shots in the dark. Thanks but no thanks HP. I would love to Office Space this friggin' printer but I'll hold off for now..

I experince the exact same issues and have for most of the time I have owned my C310A. I've gone through all the firmware upgrades, the useless patches etc. something is WRONG with the printer as my power modules continues to pump out the voltage after the printer shuts down(I've confirmed with a voltmeter). My printer will be printing a photo and the display will shut off, the power light and wireless LED lights go off BUT the photo continues to printer and the carriage will return to its resting spot THEN remain unresponsive till I go through the unplug routine. It's no wonder HP discontinued this printer and I'm throughly disgusted at tthe lack of quality in the components. I('ve gone through at leat 5 HP printers in the last6 years, each printer failing to either power issues or ink delivery systems. There is a very obvious lack of quality control. I feel as thoughHP sells the shoddy printers to force continual upgrades and flow of ink sales. The design and engineering and features of the C310 A is to be commended but the qulaity and reliabilty of the mfg. product is abysmaly horrible. HP once had a solid quality control methodology that was second to none now its just too little and too late.

Dv6 power led not working

Hi everybody!
Today, I changed the fan in my Pavilion dv6-6001eh (the original stop working). After I assembly, the power led not working anymore. I check the cable, but that's ok. Otherwise the power button working. The second power led in the right side next to USB, also not working.
Why? Maybe pressed hotkey?
Thank you.

Any advice?

My Power Led Not Turn Off

hello,
When i turn off my PC " Manually (With the Button)" the power led stays always on. When Windows Turns off the PC the led turn off. I don't understand what's happening.
Help me!!!

Hi:
Did you make sure that the cables are connected the way it should?
Look at your MOBO manual and see how to connect the power led. Maybe you're missing something.

Samsung SCH-LC11 4G Hotspot 4g LED not lit

Just got the Samsung SCH-LC11 4G Hotspot today. I live in an area where 4g is not available. The 3G LED is green and I have no issue accessing the internet but the 4G led is not lit at all. The manual gives no reason for the led to be dark. Any ideas?

Which lights for 4G / EVDO indicates which mode the Hotspot is working in. Only 1 mode can be used at a time.
If you are in an area where there is no 4G then the modem is not operating in 4G mode so the EVDO light should be lit instead.
You can see the modem status by using the Admin Web GUI (http://192.168.1.1) under Configuration -> Diagnostics.
When you press the Modem button, it will display info about the modem values, 2 of which will be the Signal for EVDO and 4G.

Dropped 3gs into lake for 2 hours. Found and put in rice for sev. days. Will come on when connected to power, but not pc. Goes out after min. or so. Will it likely work again without service or am I dreaming?

As mentioned above, I dropped my Iphone 3gs into lake and it took me about two hours to fish it out. I put it in a jar of rice for over a week. It will now come on only if I plug it into the electrical oulet. It will not come on using the usb connection on the pc. It also cuts out after a short time - usually about a minute or so. Will this phone likely work correctly again without major service or should I just forget it? I have aready bought a replacement to use, but I hate to just toss it if it may work again. Also, is there anything else I can do short of taking it in to the Apple store? I suspect the cost of service will not be justified.

You are welcome. There are always suggestions of things to try, but in the end you just get frustrated and end up taking it in anyway...save yourself the trouble and visit the Apple store genius bar.

Befw11s4 Dead Radio - LEDs not lit, no signal - help!

Hi Linksys,
I've got several Linksys devices, including a G-router, and they're great.
But that's not what I'm writing about today....
In short: I fiddled with the WiFi in a vacation rental house, and I think I broke it.
The long:
I'm renting a house on cape cod, and they have a befw11s4 wifi router.
When we arrived, it was working. But since the SSID was broadcast as
"linksys", I was worried about privacy. So I logged in using the default
password "admin", and discovered that it was a typical default situation.
So I decided to turn on security for the week, then I'd turn it off. No
big deal, right?
Unfortunately, after turning on WEP security (it doesn't seem to have
WPA), the radio went dead. So I did a factory reset from the button, and
that didn't help. Then I hardwired with cat5 and did a factory reset
within the admin interface, and the radio is still dead. By "dead", I
mean that no SSID shows up at all. And the WLan lights (WLAN Activity,
WLAN Link) do not light up - ever. The setup screen looks like this:
Wireless: [x] Enable
SSID: linksys
Channel: 6
WEP: [x] Disable
Here is a screenshot:
http://www.thornsoft.com/Misc/linksys_setup.JPG
I've tried disabling/enabling the wireless, changing the SSID, switching
channels. I also have analyzed the WiFi with my spectrum analyzer
(doesn't everyone have one?) and it shows no radio signals in the 2.4Ghz
band, aside from my own Linksys router on channel 3, which I'm currently
using as an access point (I brought it in case the one in the rental unit
wasn't able to be secured!) Aside from my traffic on ch3, there's nothing
going on, including microwave ovens, baby monitors, etc... And I've tested
as close as 4 feet from the device.
Here's a screenshot, showing absolutely no traffic on ch6. You see my wifi router on ch3, but the one that I'm trying to fix is on ch6. Nothing, zilch, nada:
http://www.thornsoft.com/Misc/linksys_wifi_spectrum.JPG
Any ideas? Would upgrading firmware help? It's currently at 1.44.2z. I
don't know the rev of the device, as it's bolted to the wall.
Let me know what you think. If I've broken the radio, I'm just going to
install my router in place of theirs, and leave it behind. I'd rather buy
myself a new router than risk my $400 cleaning deposit...
Thanks,
Chris Thornton

Thanks for the reply.
This router is "rev 0" I guess, as it doesn't indicate a rev with the model number. So I'm already at the latest firmware for that rev (1.44.2z).
I re-flashed it anyway, just for kicks. Reset switch, then power off for an hour. Radio is still dead.
We're going to scrap it, switch in my working WRT54G, and the owner of the house is going to re-imburse me. I'll probably pick up a new WRT54G when I get home.
Anyway, it would be really helpful if you could indicate whether these radios do just quit, out of the blue like that.

PWR OK LED not lit

Hi,
I have a PXI-8108 and when I switch it on nothing happens, not even the PWR OK LED lights up. If i plug a network cable in the ACT/LINK LED does flash.
I have tried clearing the CMOS by holding SW2 down for 3 seconds, but still nothing.
Any other ideas I can try before sending it back for repair?
Many thanks,
Sarah

Hi Sarah,
This sounds like a simple repair then!
If you contact NI UK Customer Services, they will be able to sort an RMA (Return Material Authorisation) so we can repair your controller. Below is a link to the contact info.

Does KM4M-L have power LED?

Does the KM4M-L (VIA KM400 MicroATX motherboard) have an onboard LED showing whether the board has power? I don't mean pins for a front-panel LED, but an LED soldered right on the motherboard?
I've searched the online manual and scoured the photos, but have found no proof that one exists.
David

Nope "Bas" is Correct; as MSI Does Not Have onboard Power LED'S, My ABIT Board Has 2 Red For Standby Power, and Green For Board in Operation, And My Wife Hates Them, As I have the ABIT PC in the TV Room, and with the Clear Side Cover the RED LED Shines Right At the Corner of My Wifes Eyes (It is Freakin Bright I have to Admit) while She Watches TV As it is Just enough to Distract Her ...I always wonderd why she would have a Towel Covering the PC when it was Off, Until I sat on Her Couch and Had that bright LED Catching my eye..So She says to Me " My MSI i865-PFSIR Doesn't have that That Aggravating Freakin Light, What the Hell Good is it anyway, You need a Freakin Light to tell You That the PC is Off!!!" ..Women , So easy Aggravated..............Sean REILLY875

27'' LED Cinema Display flickers when powering MBP and dimmed down

The 27'' LED Cinema Display flickers (backlight flickers) in the following situation:
* The display powers an MacBook Pro (e.g. later 2010).
* The MacBook Pro is fully charged (i.e. power is not used for charging).
* The MacBook Pro performs some GPU intense task (moving the mouse over the dock with magnification enabled).
* The brightness of the display is dimmed down to one of the lower settings (one or two "bars").
The problem disappears if the MBP is powered by an independent charger.
We reproduced the problem with two different MBPs (13'' and 15'') and two different displays.

Same problem here! I bought two brand new 27 inch Cinema Displays, one for work and one for my home office. Both showed the problem. I returned both, go replacement displays and both show the same problem. I am using them with a 13 inch MacBook Air late 2010. I use them with the MacBook's display lid closed and powered by the Cinema Display. The problem only occurs when the display brightness is at 1 to 5 bars. From 6 bars on everything is fine. I also noticed that the flickering is stronger when I USE the computer, i.e. dragging around windows, typing, etc. When I just look at the screen, the flickering occurs more sporadically. The flickering looks like a short switching off of the display light (a few milliseconds).
I just tried the hint suggested in this thread and indeed, when I open the lid and have the MacBook running on batteries (not powered by the Cinema Display), the flickering is gone! So it really seems to be dependent on that.
Please fix it, Apple! This is not acceptable for a premium-quality display! We have already done a good job narrowing down the conditions under which the problem occurs. You should easily be able to reproduce the issue like this:
- use a MacBook (e.g. new MacBook Air) and turn it on
- plug in all three cables provided by the 27" Cinema Display (power, DisplayPort, USB)
- close the lid of the MacBook and re-awake it with an external keyboard so the Cinema Display will be the only display in use
- wait a few hours for the Cinema Display to become warm (not sure if this is a necessary condition but it could be)
- then, use the computer under low-light conditions and ensure the brightness is at 5 bars or less
--> You will see the problem.
By the way, the recent Cinema Display firmware update (to address the audio issue) did NOT solve this problem.

Computer does not turn on, power LED goes off when power button is pressed

My Pavilion 17-e078nr has stopped working, it will not power on. When you push the power button, the power LED next to where the plug is goes off and takes several minutes before it comes back on. I've tried removing the battery and get the same results and with the batter in and AC disconnected the power button does nothing. I've also tried the hard reset with no luck. As far as I know, nothing has happened to the computer since last time it worked. My two theories are either the AC power is bad, or there is a problem internal to the laptop. The AC power is providing the 19.5V, I measured it using a multi meter, I'm just not sure if it's providing the required wattage, or if the connection to the laptop is secure, it feels a little loose, but at the same time the LED comes on, so I know it's getting a connection. Only thing I can think to try is go to a store that sells this type of computer and see if I can use one of their power supplies to power my computer, and/or plug my supply into one of their computers. Don't know how willing any store would be to allow me to do that though. Any one have any additional thoughts or advise?

Hi! I have the exact same problem... the LED on adapter, is very, very dim when connected.
At first I tried connecting my macbook to my roommate's adapter and had the same problem. then tried taking out the battery, and still had the same problem. I did the same thing with my roommate's macbook, but hers did actually turn on! it operated without the battery. Figured out it was problem with mine.
I kept on trying combinations battery, computer and adapter. turns our that my battery (which I thought at first was the problem) charges perfectly on my roommates mac, but wont charge on mine. her adapter won't work either on my computer. What I've been doing is charging my battery on her computer, then placing it on my mac, and it works. only thing that won't work is the adapter.
Went to a mac store, and they told me that the problem was a small cable o wire that went from the Magsafe point into the mac and that the LED was very dim because no energy was being drawn from that spot because of this little wire being broken. they gave me the name of this wire... very technical stuff so, completely forgot cause I didn't have anything near to write on.
I'd like to know if anyone has gone through this same ordeal, and had this wire replaced without any problems. When it comes to opening up my mac, I'm a bit skeptical, since warranty is expired and wouldn't want for a solution to become a bigger problem.

My mac mini only shows a steady power light and fan noise when powered up. No video or sound and no commumication with wired keyboard or optical mouse. Tried replacing internal battery and resetting PMU/SMC but nothing seemed to happen. Any suggestions?

You've already done the two things I would have suggested.
If your Mini has an internal battery then I assume it's a G4. That means you've gotten a lot of good years of service from it, and it's old enough that it's certainly not covered by AppleCare anymore, and it's probably not worth spending money trying to repair it.
You should be able to tear it apart using instructions from ifixit.com to get the hard drive out, and then put the hard drive into a nice USB or FireWire enclosure (I like the ones from Other World Computing, macsales.com) so you can transfer your data to a replacement Mac.
I hope someone has another suggestion for you.

P67a-gd65 b3 Not powering up but power LED goes on

This computer I built has been running for several months with no problems. Last night I left it on and when I got up it today it was off.
Almost positive its a hardware problem as nothing new has been added or changed. Looking to see if anyone else had the same symptoms to help identify what component may be causing it.
When I unplug the machine from power, and plug it back in no LEDs light up (as expected from what I remember when building it).
When I press the power button on the case, or the power button on the motherboard, that power LED lights up but that is the only thing that seems to happen. None of the LEDs on the top by the CPU light up, the fans never spin, and no post.
First thoughts would be psu, cpu, or motherboard.
The type of psu (seasonic x series) I have would only spin its fans some of the time depending on load. So the lack of psu fan activity isn't abnormal.
Thanks

Power led flash when i try to start up my Mac Pro.

I have a Mac Pro (Early 2008). I have now got a problem. I can't start it up.
When i start it by pressing the Power switch the fans inside start to sound and the powerled beside the power swich starts flashing.
After that nothing more happens ( i have waitind for several hours), I have to stop the Mac by pressing the Power switch.
It looks like the Ram is OK becouse the lams on the Ram boards lights up abd then turns of agian (no indication of error);
i have changed to backup battery and reset the PARAM and SMC with no effect. i have also removed all extra Harddisks and also
the Graphic card to see if ther was any problems with these.
So i guess the the flasing Power led is an indication somthing is wrong but i can't find an expanation when i search the net.

So i guess the the flasing Power led is an indication somthing is wrong but i can't find an expanation when i search the net.
Yes it is.
If it is single flashes something is wrong with your ram. A red diagnostic led may be lit on the riser that failed.
If the flashes are in groups of 3 a bad dimm slot (or slots) were detected and there should be lit diagnostic leds next (or near) to the dimms that failed.
Try reseating your dimm no matter how it is blinking. But look inside for lit diagnostic leds anyhow.
Also blow all the dust out of your machine while you are in there.

Satellite L650-12Z: Led does not light up when connected to power source

My L650 does not show the white light anymore when the cable is plugged in.
The connectors are clean, and the adapter is working.
The laptop does still run on the battery ( when there was still power in it).
Also without the battery, there is no white light indicating that the laptop is connected to the DC.
Does anyone know what the problem could be and how to solve it?

Thanks for your reply.
Unfortunately the battery does not charge when connected.
Only when connected with the full battery it is working.
I have measured the adapter with my multimeter and it seems to be working properly.
Like you said, letting a technician look at it would be a smart idea.
I decided to send it to a service center in my city, in about 4 weeks I would have the notebook back they said.
Weird thing for me still is, that around three weeks ago the same happened. Windows said the power was not connected. But after plugging the power in and out a few times it worked again. Maybe this is a symptom of something?
