Dell :: LED Lights Come On For Seconds And Then Go Off

Nov 10, 2008

turning on then turning off? When I turn it on, the LED lights come on for seconds and then go off. I replaced the motherboard and the processor and its still the same problem. I also took out the RAM and had the same problem?

What else could be causing it? The graphics card?

HP/Compaq :: DV6000- Lights Turn On For 2 Seconds, And It Shuts Right Off

Nov 11, 2009

I have a HP DV6000 Laptop. Im aware of the problems these models have. But this one I have not yet heard of. When I attempt to power it on, the lights turn on for 2 seconds, and it shuts right off. Its not like the Video card issue everyone speaks of. I have extensive technical background, and I have tried taking everything out, and trying each part one by one. I have tried swapping the power button ribbons, I have tried removing the bios battery. I guess im wondering if anyone else has ever been able to figure out whats going wrong with this setup? copuld it be a lack of contact between heat sync and CPU? please give me whatever input you can. I would like to not have to spring for a new Mobo. I can solder, and I am thinking of trying to heat the soldering points with a heat gun maybe. I dont know if thats the problem tho. and also, when the AC adaptor is plugged in, the blue LED surrounding it is on.

I also tried all this (of course)

1. Remove battery.
2. Remove AC power.
3. Remove and reseat your RAM modules.
4. Replace your RAM modules.
5. Hold down your power button for 1 minute.
6. Replace your AC power (not battery) and turn on
remove the small bios cmos battery for 15min and then put it back in

Then has soon has it boots into windows they will go back to my setting of sapphire blue.

Dell :: Blinking Lights On The M1730

Nov 2, 2008

I suffer from migraine that is triggered by changes in luminosity and blinking lights.

I am now reading the review by justGoIt of the M1730 on the Dell website: it talks about "bling bling lights". (This link points to the product, then you have to click on reviews.)

Does anybody know what lights are they?

can they be turned off?

are they bright?

where are they positioned?

or can they just be covered with a sticker?

Dell :: Lights On The M1710 Cover

Dec 5, 2007

anyone at all been able to light up the cover lights (just one of the colors even) for those who have done the 9400/E1705 to M1710 mods? I would really like to know how this can be done if there are some theories out there. Please refrain from saying how much you hate the lights or asking why I would care to do this :

Some methods I thought about trying:
USB port: 5V ok, will that work with the cover LEDs?
Fan port: I have heard this one might not work but can anyone confirm?

(I am talking about cutting off the connector that would originally go into the M1710 mobo and trying various things with the wires that happen to be color coded, 2 for each color of LED apparently.)

Dell :: XPS M1730 Back Lights??

May 5, 2009

i recently reinstalled windows on my Dell XPS M1730 but i have some problems. For some reason the lights on the lid of the case (the ones on top lol) dont come on anymore.

To get them on i have to open dell quickset and turn them off and then on again, then they will stay on, but after shutting down and booting back up they are still off. Anyone know what the problem could be?

Also another issue im having is that when i turn on the laptop my left speaker light is orange. I changed it in quickset to be blue but still during booting its orange and then once the laptop is fully booted it turns to blue. Anyone have any idea how to fix this?

Dell :: M4400 Freezes For 1 Second Every 10-20 Seconds

May 5, 2009

Because of various problems I was having with my M4400, I decided to reformat and reinstall Windows (Vista Ultimate SP1).

Immediately after reinstalling, it started to freeze for up to 1 second every 10 to 20 seconds, which is really annoying. However, it doesn't miss any keystrokes or mouse movements, as it catches up after the freeze. I'm wondering whether it's got something to do with some unrecognised devices that it has yet to find the drivers for:

PCI Serial Port
PCI Simple Communications Controller
SM Bus Controller

Dell :: Disable XPS Lights On Screen Hinge?

Dec 13, 2009

I know it's kinda dumb but it's annoyingly bright when I've got the computer on at night and it's busy converting video or doing other work. It's also less power used.

It can't be done through software but has anyone physically unplugged them? I've not opened up the case yet so I don't know how practical that would be, thought I'd ask around first.

Dell :: SXPS16 Brighter Keyboard Lights?

Mar 9, 2010

I feel like the keyboard on my SXPS13 was MUCH brighter than the keyboard on my SXPS16.

I also had an icon pop up on the RHS of the screen that told me the keyboard light level (it would pop up when changing intensity 'off', '1', and '2').

I don't have an icon pop up on the 16, and the keyboard looks much dimmer overall.

Dell :: E1705, Freezing In Games After About 20 Seconds

Dec 28, 2009

I was playing a game of borderlands online and its started off running fine and then after about 20 seconds started lagging badly and then froze.

I assumed it was some kind of network connection problem considering i was playing the game fine a few days earlier. Well i forgot about it for a few days.

I just downloaded the battleswarm beta and was playing it and noticed it did the exact same thing, ran fine for about 20-30 seconds started lagging badly then just froze. I went back and tried borderlands in single player to confirm the problem and it also did the same thing.

Dell Inspiron N5010 :: Won't Turn On - No Beeps / Lights

Feb 7, 2013

I recently changed the screens on my laptop without difficulty. The next day i went to classes and brought my laptop since it was now fixed. When i went to turn it on it was very dark and i couldn't adjust the brightness. I couldn't get pass the log on screen so i held down the power button but it would not turn off so i took out the battery. I put the battery back in and left the laptop alone till i got home. I thought that the problem with the screen was a wire came loose or something of that nature so i took apart the screen and made sure everything was plugged in. I put it back together and put the battery back in and went to turn it on to see if the screen problem was resolved and it wouldn't boot or anything. I don't get any beeps, fans, or lights that turn on.

Dell XPS L421X :: Will Not Power Up - No Back Lights On Keyboard

Mar 30, 2013

This is the second time I have had this issue. I have already had the motherboard and power supply/cable replaced and it worked for awhile. Here is the issue.

- Occasionally after powering down, the next time I try to power up, the laptop does nothing but show the power light on. No Dell screen, no back lights on the keyboard, nothing else. I press and hold the power button down and after 5 seconds it shuts the light off.  I would then try it again with the same result. I let the battery completely drain; plug the power cord back in and after about 5 minutes of charging, try it again. This seemed to work until one day it did not. Then I had the motherboard and power supply replaced and all seemed well.  Now, 6-8 weeks later I have the same problem again.  A new L421X purchased in December 2012 with 512GB SSD running Windows 8 64 bit. I use this for business and am about to throw it out the window.  

Currently, I have tried the power up, drain power trick with no results. It is dead with all my business info on the drive.  I am about to dump Dell and switch to HP.  

Anything I can do short of a whole new machine?

Apple :: Yellow Lights When Looking Through The Vents

Feb 22, 2009

i've been playing far cry 2 for 4 hours. i shut down the game, my temp is 79-80 degrees celcius which is perfectly normal when gaming on the macbook pro. i don't know why i wanted to look through the vents. i turn my laptop and look through. i saw this yellow light. its approximately under the R and F keys on the keyboard. i turn my laptop and look closely on the keyboard and it's illuminated white. no sign of the yellow light. Thus, to resume, i saw it only when looking through the vents. does anybody know what is this light? what is causing it to light up? i smelled closely but no burning smell. in fact, i cant smell any weird odour. is it harmful for my macbook pro?

Dell Inspiron N5010 :: Won't Stay On For Longer Than 30 Seconds

Jan 30, 2013

Had a laptop for just over 2 years so out of warranty. The laptop will not stay on for longer than 30 seconds - 1 minute, it doesn't matter what I'm doing (tried going into everything, Bios, safe mode, etc). I've bought a new battery and nothing has changed.

The laptop has had overheating problems in the past, whereby it would turn off if the fan was in someway impeded. Since this problem I have tried blowing into the fan and even used a hoover but nothing has worked. 

Does it sound like its an issue with a fan or something else?

Dell Inspiron N5010 :: Shuts Off While Booting In 10-15 Seconds

Jun 10, 2012

Dell inspiron N5010 laptop. When ever I carry my laptop to some place lets say from home to college it stops booting, when I switch on my laptop it starts but after 10-15 seconds it shuts off, also when I try to keep the system in bios it again shuts off within 10-15 seconds.

Twist in the problem is that if I keep my laptop idle for 20-30 minutes it starts working fine (I never remove battery or ram just left my laptop idle)

Another thing is i face this problem only when laptop is carried by me in my back pack or u can say when laptop is subjected to movement.

I noticed this pattern seriously. For past 15 days I didn't displaced my laptop from my desk and it work like any normal laptop but today when I took it to my friends place and there when I tried to boot it it starts and shuts off within 15 seconds while booting so I did the same left it idle without even removing ram or battery or charger for 10 -15 minutes and then it starts working fine.

Why is this happening is there is a problem i hardware or just some loose connection.

Dell Inspiron 14 1440 :: Screen Is Black There Are No Blue Lights That Are On

Nov 25, 2014

My Dell Inspiron 14 1440 froze and i decided to manually turn it on and back on. I pushed, and held the power button until it turned off. Once it turned off i decided to take the battery out (for no apparent reason). So i took it out and put it back it (i didn't really touch anything). Once i put it back in i tried turning it on by pressing the power button, but it wouldn't turn on. The screen is black, there are no blue lights that are on. (These lights are on when you turn the laptop on).I tried the taking out the battery and hold power button for 30-60secs trick, but no luck. I also have taken out my laptop's ram and re-inserted it (same with my hard drive). Oh and my battery is fully charged. I tried searching the net for solutions but no one really has the same problem as me. Most of the other people with problems said they could hear the fan, but with mine there is noting. No sound. No lights. No working laptop just one really expensive door stop.

HP/Compaq :: HP Ze4904us Wont Boot, But Lights Are On

Apr 6, 2009

It's an HP ze 4904US running windows XP. Worked fine, then went to start one day and screen wouldn't come on. Having had this problem with my ze1000 series, I thought it could be screen bulb or inverter. But it isn't.

When I turn it on, I see the blue light all the way to the left on as well as the orange light by the battery symbol to the right.
I don't hear beeps.
I do hear the cd rom spin if a cd is loaded.
I do hear the fan for just a second occasionally. Not every time.
The screen is black and no faint xp logo or anything.
I feel like maybe it's not booting all the way.
If I press caps lock or num lock, the accent light doesnt come one. (maybe bad keyboard)

Here's what I've tested so far based on searches on this forum:

used reset button
removed battery and ac adapter and held power button 1 min.
One by one removed hardware to narrow problem
Re-seated everything and made sure connections were good
tried 2 other known working ac adapters.
hooked up to my PC monitor and still nothing. Monitor doesn't noticed anything attached. (why I believe it's not screen and just isnt booting.)

If it ends up being the motherboard, I do have a motherboard that works in my ze1000 laptop, but I don't know if it is compatible.
