Dell Inspiron 15 :: Will Not Boot Up - Power Supply Light Blinks On And Off

Feb 5, 2013

My Dell Inspiron 15 will not boot up. Started randomly shutting down over a week period. Would also display a plaid screen which would require a hard shut down by me.  I was trying to run Dell diagnostics on it and noted that the video card failed, but it could not complete the diagnostic without shutting down.  Now the power supply light blinks on and off in a 10 second interval.  It acts like it has no power, but I know the battery was charged.

Acer TravelMate 5760 :: Does Not Power Up - Led Light Blinks Orange Few Times

Dec 28, 2014

The laptop is just over a year old, and does not power up at all. This started a couple of weeks ago. At first the LED light would blink orange a few times when the laptop was switched on, but nothing else happened. Then it might just start up, and while booting up the battery light would blink and it would switch off .

I did try removing the battery etc. to discharge of the mainboard as advised, but no difference. I have tried other sockets, same result. I have now left it unplugged for a few days and there is not even the orange light any more.

Acer Aspire V3 551-8469 :: Power Indicator Light Blinks Several Times But Not Turn On

Feb 25, 2015

I have an Acer Aspire V3 551 8469. It is out of warranty. The indicator power light blinks 4 to 5 times and nothing happens after.  I got adventurous and opened it up. I replaces the cord that receives the power coupling from the ac. Still not working. I was told it could be the motherboard but there is no guarantee that is the issue. If it is the mother board I will just have to get one and put it in.

Lenovo ThinkPad Yoga S Series :: S1 Won't Boot / Only Blinks Light Three Times

Nov 15, 2014

I just purchased a refurbished Thinkpad Yoga, and all was great for a little while. Then I decided to shut it down and set it aside for a few minutes.
 
Current Status: System responds in no way other than the 'i' light (in the Thinkpad logo) blinking three times when the charger is connected, or the same when the reset button is pressed while the charger is still connected. Nothing else illicits any sort of beep, light, or otherwise.

HP ProBook 4510s :: Blue Light On Power On Button Lights For 6 Seconds And LED Blinks 13 Times

Oct 27, 2011

Laptop: Hp ProBook 4510s
 
When I turn my laptop on, the blue light on the power on button lights for 6 seconds, meanwhile the led near the power plug on right side rapidly blinks 13 times. Always exactly 13 times, so it must be some kind of error code. Then laptop shuts down. Nothing is heard, neither fan, neither hard disk.

Acer :: Aspire 7220 Flashing Power Light, Doesn't Boot

Feb 26, 2010

I'm trying to fix my fathers laptop so he won't have to spend money on a new one. Here's the problem:

When I press the power button to boot the laptop it does not boot, it just flashes the power light(s) on and off at maybe 1 flash per second. I've tried removing the RAM-sticks one and one, removing the HDD, removing the battery and removing the DVD reader (not all at the same time, of course). None of those helped, it still did the same thing.

Then I tried to blind flash the bios from a CD, the laptop comes on with the fan at full blast, the DVD reader comes on and it stays on, but it never finishes and powers off.

Acer Aspire 5552G :: Power Light But Only A Black Screen On Startup (boot Sector On HD)

Dec 5, 2014

I had exactly the same problem with my Acer Aspire 5552G with win7, I tried all things that was online e.g. New battery, Flashing bios, Fn + esc without battery when trying to start the computer and so on.
 
It started now and then and worked perfect but when I shut it down again it could take me up to 50 tries to get it started.
 
The problem was issues with the boot sector on the hard drive!
 
Finally I made an Win7 repair disc and started from.
 
I also checked for errors on the hard drive and it repaired some sectors before starting windows.
 
After that it works like when it was new. The computer was bought January 2011.

Dell :: Is There A Power Supply Gremlin?

Apr 26, 2009

Ive seen 2 fairly new Dell laptops recently (a Latitude D520 and an Inspiron E1705) with the same symptoms. With a known good adapter attached to the unit, they do not charge at all,

but they run off the battery until the battery dies. I disassembled both and checked the connection between the power jack and the mobo and found them to be solid.

I connected a power source directly to the + solder point on the mobo and a ground and found they did not power up at all. If this were a desktop, I would change the power supply immediately, but being a laptop, Im not sure what (if anything) can be done to fix the problem. Any ideas or suggestions would be very much appreciated.

What I've done:
1. Both units work normally with charged batteries, so I know I'm working with good laptops.
2. Removed, cleaned contacts and re-inserted RAM.
3. Cleaned accumulation from the internal lint trap, i.e., from the CPU cooling fins.
4. Removed, cleaned, re-applied thermal paste and reseated CPU'

Dell :: Universal Power Supply

Sep 27, 2009

So i have a new e6400 moved from an e4200. Figured I could use the nice dell travel adapter I had with my 4200. Once i plugged it into my new beast i got a not enough wattage message from DCP.

Which is fine, I now realize that my nice slim power adapter is very much under powered for this laptop.

I went out and got a Cooler Master SNA 95 it is a 95 watt adaptor and acutally is really small and light. Got it home and plugged it in and I got this message .....

Dell Inspiron 14z :: 5423 Won't Start - No Power Light

Dec 7, 2014

Last night I closed my Dell Inspiron 14z - 1523 when it was almost out of power. Later that night I was not able to turn it on again. Power indicator on the AC adapter is on, but when I do the AC adapter in my laptop the power indicator of my laptop stays off (when plugged in the power indicator of the AC adapter is a little less strong four half a second or so).

I read some topics on this forum and discovered the reset button at the back of the laptop. I tried this option, hope it would solve the issue, but the issue remain...

Dell Inspiron 15 3521 :: No Light On Power Button?

Jan 10, 2015

I just bought a new laptop as mentioned in the subject and am wondering...

The power button on this laptop never lights up at all. 

I can't tell that pressing the power button has done anything at all until I see the screen come on.

Is that normal for this brand of Dell?  I mean to have no light on the power button indicating that it has been pressed?

Dell Inspiron 1545 :: Laptop Would Not Power Up - No Light?

Jan 16, 2015

This is a late 2008 build Dell Inspiron 1545, sold retail in December 2010.

Pentium dual core T4500, 2.3 GHz

Has been in irregular use as a spare machine, mains adapter only, battery  removed.  My house was struck by lightning over a year ago and adapter damaged.  Replaced adapter and no further issue until now.

Laptop would not power up, no light.  Tested adapter and tried another 2 adapters - still no power up.  Replaced original adapter and plugged in depleted battery - powered up but had to press F1.  Powered up with no issue with good battery.  Once powered up the laptop seems to be charging battery OK.  Guessed this was a power board issue but no change when replacement fitted.

Dell :: Power Supply Model # Matter Much?

May 1, 2010

needed a new charger, dell listed 5 options for my service tag #. So I called them and the guy in india said said the NF599 was the one I need if I wanted the 6' cord.

Put NF599 into amazon and ordered one, received a UU572. Specs all appear to be the same, this one doesnt say 90w anywhere on it but the specs online all say 90w. Its also a 3 prong and not a 2 prong like the NF599, that may actually be nice so it doesnt fall out of the socket so easily.

Dell Inspiron 1425 :: Power Light Is On But Screen Is Blank

Apr 2, 2013

My laptop was working fine till yesterday night. I had left it with the power cable connected and it had gone to sleep. Today morning I tried to switch it on but the screen wont show anything. I switced it off (using press and hold the power button) and now the laptop wont start. When I press the power button, the power light comes on, the hard-disk light switches on for a second and turns off and the screen is always blank. This happens regardless of the laptop being connect using battery or power cable. I have tried pressing the Fn key along with the lcd screen key and the screen did show up some tests in a blue screen and they were all a pass. But when i try to do a nromal boot, the screen never shows anything.

Dell Inspiron 9300 :: Green Power Light Only For 4 Seconds

Apr 18, 2013

Dell Inspiron 9300:
Part Number: PP14l

The battery on it flashes 3 out of 5 lights but not in order. The two end lights and the middle light comes in. They flash in unison 3 times before turning off. Anyway I plugged in 2 different chargers to the computer and the battery light on the pc flashes 3 or 4 orange and then 1 green. Then it resumes the light cycle just mentioned. The computer gives ZERO response to this whatsoever. If I unplug the ac adapter, the computer turns on for four seconds. No hdd noise, no fans, just a green power light ONLY. Not sure how to fix this or what it is, but nobody in the forums or on youtube or google seem to have solutions or even the same issue. I have tried reseating both ram, unplugging the wifi chip, dvd drive, doing the 20 second power drain without battery hooked up. All the same responses, just nothing....

Dell Latitude E6510 :: Will Not Start / Power Light Goes On Briefly / Battery Light Flashes

Oct 24, 2011

I have a Latitude E6510 that will not start.  When pressing the power button, the power light goes on for about 5 seconds and then turns off.  I also notice the battery light flashes a few times when re-connecting the AC adapter.

Removed the battery, held in the power button 30 seconds, but still not working.

We have had this laptop about 6 months.  About a month ago, it exhibited this problem.  After talking to Dell Support, they recommended a system board replacement.  The laptop was sent in and the board was replaced.  When I got it back and tried to start it for the first time, it did the same thing.  I then pressed the Latitude "ON" button, and the laptop started.

Now it is doing the same thing, and I find it hard to believe that another system board is bad.  I am suspicious about this "ON" feature, that maybe the laptop is "stuck" or something trying to get into the "ON" mode.  Or maybe it is just trying to get into "ON" mode. 

I am not sure what the "ON" feature does, but I have noticed a few other posts on the internet of users having the exact same problem.  Again--I find it hard to believe a second system board could be bad.

Dell Inspiron 1526 :: No Boot Up - Flashing LED Light

Feb 3, 2013

I have been having problems getting my laptop to boot. I've performed a laundry list of repair options and nothing has worked. As of this moment, I've managed to narrow the query down to the flashing LED light code FLASHING Num Lock-SOLID Caps Lock-Solid Scroll Lock. I've done some further research and I've only managed to get sketchy information at best. It is saying that the problem has something to do with the processor or the system dock--if that information is reliable. I've had contradicting answers on that. I've reseated the processor several times, even switching the processor with a virtually identical processor from my WORKING Inspiron 1501 with no change. And just to confirm that the processor initially seated in the 1526 is working, I have put it in the 1501 and it works. I've swapped compatible components between both machines and everything has worked after being seated in the 1501.

To recap the light code...Flash/Solid/Solid.
