Dell Studio 1749 :: 3 Blinking Lights But Will Not Power On

Aug 12, 2014

My daughter's 1749 laptop shut itself off and now when you plugin the power adapter, the light over the plug on the laptop blinks three times.  It will not power on at all.

I have replaced the power jack in the laptop as well as the cpu and tried different known-good ram but nothing makes any difference. What does the light over the power jack blinking three times indicate?

Dell :: E1505 Won't Boot, No Post, 3 Indicator Lights + Power Blinking...

Mar 10, 2010

The laptop wouldn't boot. I took the keyboard out to see if I could swab-dry any water, but couldn't really find any in there.

I lightly sprayed around with compressed air and left the laptop open with the keyboard out to try and let it dry out for a few hours, but no dice...still wouldn't boot.

I thought maybe via cell phone logic, it might work again after 24 hours or so. It's been almost three days now and it still won't boot, so I'm pretty sure I fried something. Here's the error code it's giving me .....

Dell :: Inspiron 8200 Unable To Bootthree Blinking Lights On Power On

Aug 9, 2007

I tried turning it on today and at first it wouldn't turn on at all. I switched power outlets and when I pressed the power button, it turned on but the three green lights (power, HDD and battery) started blinking for a few seconds before the system shuts off.

I can't really find if this is some kind of error code or whatnot. I've tried reseating everything except the CPU... I've done the memory, DVD-ROM, HDD, Keyboard, Graphics card... I just don't know what it could be and I have no idea who I could even take the machine to.

Dell Studio 1749 :: Power Adapter Is Plugged Into power Board Along Side Of Laptop

Jan 27, 2013

Our Studio 1749 will retain a solid connection when the power adapter is plugged into the power board along the side of my laptop. I am unsure if the pins residing in the power board are pushed toward each other so as to not retain connection when the adpater in plugged into the laptop.

Dell Studio 1749 :: Stop Charging - Laptop Won't Power Up With Battery Removed

Mar 8, 2010

Last Friday i received my new Studio 1749 with i3. As told by the documentation I put in the battery, put the power cable in the ac-adapter, pluged the AC-cable into the laptop and then pluged the ac-adapter into the wall outlet. I booted the laptop and once I was on the windows desktop had a look at the battery symbol. It showed that the laptop was connected to external power and that the battery was being charged.

I wen't away from the laptop to let it charge the battery for 12 hours as told by the documentation. After two hours i came back to have a look at the laptop and it was off. Curious I turned it on again. After booting up it showed the battery at 60% and the laptop running from battery. Yet the ac-adapter was connected to the laptop. I hadn't changed anything. I pluged the adapter cable in and out, but it wouldn't recognize that the was external power available. Turning the laptop off an on again didn't work either.

Now I feared for the battery. My guess is that at one point it started to run on battery power even though it was not charged for 12 hours. Then when the battery was depleted the laptop shut down. This might have permanently damaged the battery!

I guess as soon as the laptop was off the ac-adapter charged the battery again, and when I came in it was just at 60%.

So I turned it off removed the ac-adapter, removed the battery, put the battery back into the laptop pluged the ac-adapter back in and booted up again. Now it showed it was running from external power again. All fine. It charged the battery as well. Actually it charged the battery up to 99% and then out of nowhere the battery symbol changed and it was running from battery AGAIN! Even though it was still connected to the ac-adapter. This happens all the time. It is reproducable.

So I thought something might be wrong with the ac-adapter.

I powered down the laptop and removed the battery. Now with only the ac-adapter connected ,I tried to start the laptop. The control lights above the keyboard came on for 2 or 3 seconds and then the laptop turned off again. Trying to hit the power button again after that didn't give another reaction.

Conclusion: The laptop won't run just on external power with no battery in the battery bay.

I put in the battery again. AC-adapter still connected. Hit power. Laptop starts to boot. Then while booting I removed the battery. Laptop keeps on booting - finishes booting - runs nice and well at full speed not missing the battery - FOREVER.

So it won't boot with the battery removed, but it will run without it flawlessly??? Strange isn't it?

Next test: I put in the battery again while the laptop is running from mains. And now it charges the battery again until the point... you already know... it "forgets" that it is connected to the ac-adapter and starts running on battery power. So now I boldly removed the battery while the laptop was running. After all it was still connected to mains/ac-power.

Dell Studio 14z :: Won't Power On - No Flashing Lights

Feb 15, 2013

I have a studio 14z that has been sitting for approximately 5 - 6 months without being connected to a power adapter or turned on.  Needless to say, when I tried to power it up via the battery, there was nothing there.  Pushing the button on the bottom of the battery does not cause any lights to flash. 

This doesn't surprise me, but even if I plug it into it's AC adapter and take the battery out, it will not power on.  Nothing happens.  No lights (except on the power adapter) no fans spinning, nothing.  If I have the battery in place, the light that is supposed to indicate that the battery is charging does not turn on.  Basically it is "dead".  It worked fine before sitting dormant. 

Is it a lost cause?  I just had it apart to check cabling, etc. and can't see anything obvious.  Is there anyway to wake it up?  I know the power adapter works as it powered another laptop just fine.

Dell Studio 1557 :: White Blinking Light - Does Not Power On

Apr 4, 2013

I have a Dell Studio 1557.   When I attempt to power on the laptop nothing happens.  I can see a white blinking power light and nothing else.   There is no other signs of life, the fans do not come on and the CD-ROM cannot be used.

It seems like the AC adapater is working as I can see the blue light around the connector.

Dell Studio 1557 :: Won't Power On - No Beeps / Lights Or Sound

Apr 5, 2013

My studio 1557 recently had a motherboard failure of some type.  When I would plug in the power cord, the blue light on the cord would go off.   I noticed this after I was reading online and the laptop suddenly, without warning shut down and would not turn back on.

A Google search suggest that this came from a motherboard failure.  I replaced the motherboard.

Now, when I plug in the power cord, the blue light stays on and it is charging the battery.  The small white light above the power cord plug-in stays white while the battery is charging.   But, when pressing the power button, nothing happens.  The white charging indicator and the blue light on the power cord stay illuminated, but the laptop will do nothing else.  No beeps, no lights, no sounds.

I assume the power button has failed.  Am I assuming correctly, or is there anything else I need to check?

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 Inspiron N5110 :: Won't Turn On / No Beeps Or Blinking Lights

Apr 1, 2013

My Dell N5110 is about 14 months old - Windows 7, 650GB HD, 8GB RAM (originally 6GB before I upgraded the memory chip). Up until about 2/2/13, I was able to turn it on, put it in hibernation, etc., but suddenly, I could not turn it on (I had it plugged in overnight, perhaps it was in Sleep mode). I saw no lights, no beeps, no black screen as described by others - just empty screen, no power, nothing.

I waited over a week before I decided to bring it in to get service (my schedule didn't permit me to do so earlier). In the meantime, I kept trying everyday to get it work - I removed the battery, I reseated the memory chips, I clicked the power button on for multiple times, held it down for 30+ seconds, clicked every key on the keyboard, used two different power adapters (one had a blue light to indicate that it was powered), tried to used the AC adapter without a battery, all to no avail.

Eight days after the initial discovery (and a few days before I had planned to bring it in), I tried once more - removed the battery, reseated the memory chips, et. al. and then clicked the power switch (did not use a power supply). Unbelievably, IT TURNED ON! I was so shocked that I immediately took all of my personal information right off and did not turn it off again until I had cleaned the hard drive off. I reluctantly shut down the PC and was able to restart it again! And it was working fine until just this past Friday (3/29/13) where it is now dead again. I think that it went into sleep mode as I just closed the monitor and I saw the lights go off.

I have a feeling that my machine went into sleep mode and it still "thinks" it is sleeping and it can't be turned back on. Perhaps what I saw earlier was the complete draining of the power resources which rendered the machine completely cold so it was able to restart? Was there a Microsoft service release that could have caused this to happen? I have not changed my power settings to prevent the machine from sleeping but if I can get it restarted again, I will definitely change the setting.

Dell Studio 1558 :: Not Booting / Battery Status Light Keeps On Blinking When Power Button Pressed

Jan 10, 2015

I have a Dell Studio 1558 laptop which is currently four years old and out of warranty.

Currently, with or without the battery with AC adapter connected when I press the power button, the power light does not light up but the battery status light keeps on blinking until the power button is pressed. I don't see any boot up screen or hear any sound of CPU fan running in the mean time. Basically, it does not start at all.

I recently got new dell authorized battery as a replacement for laptop fearing that could be source of problem. However, the new battery does no good. I checked the battery health and status and its fine.

Before this issue the laptop would start and immediately on boot screen it would shut down. So, I got it fixed from a repair service center who cleaned up the clogged cpu fan. It worked fine for two days and then the issue resurfaced.

Now, it does not start at all. I even checked with another adapter and also changed the CMOS battery (as date and time kept changing on every boot) but the issue still remains.

Also tried removing and reconnecting the RAMs one after another and then trying to boot. Also tried draining the static charge if any after removing the battery and adapter and then holding the power button for 50 seconds. Reconnecting with ac adapter with or without battery then also does not start the system.

HP Compaq CQ61-415SA OS/Software :: Notebook Stopped Working But Lights Blinking

Dec 11, 2014

I have a Compaq CQ61-415SA and it seems to have stopped working. I turned it on and it was working fine, then I left it whilst doing something else for a couple of hours, it wasn't attached to the mains supply and when I went to use it the following happened.

When you turn it on the DVD drive tries to access and a fan comes on, that's as far as it goes. The power light stays on, the power lead light comes on and stays on, the two blinking lights blink once then pause then repeat. I have read that this is probably a hardware issue, is that right and what is the next step? I have disconnected the battery and held down the power switch for 20 seconds, but nothing happens.

HP Compaq Presario CQ61-420US Lockups :: System Not Booting / Black Screen With Blinking Lights

Apr 21, 2014

I have a compaq presario CQ61-420US with similar problems below, except I have a black screen, fan turns blinking lights are the same (num lock and cap lock) but they are flashing continuously every second or 2.  I have tried the hard reset with the ram fix,  connecting an external monitor, changing the battery, and the power adapter to no avail. I also used compressed air on the vents just in case was stuffed with dust since it will overheat and may cause problems, but nothing.

One option I can think of is purchasing a new MotherBoard, but I'm trying anything else before that.

HP Compaq Presario CQ61 Recovery :: Black Screen - Numlock And Capslock Lights Blinking Twice Every Couple Of Seconds

Jul 22, 2014

I have a problem with my Compaq Presario CQ61-325ED. It won't boot. What I see is a black/blank screen, with the numlock and capslock lights blinking twice every couple of seconds.
 
According to the blink codes, it seems the BIOS has been corrupted [URL] ....  Sadly, no adequate solution is given on that page.Win + B  or Fn + B at startup does nothing, pressing all the arrow keys gives me a continuous blinking pattern (edit: I can't seem to replicate this anymore...). I have also tried creating a bootable USB-stick with a BIOS update, but I don't think I have done it correctly, for it never gets activated (the light on the USB never turns on).

Also, removing/resetting the RAMs or just one of the RAMs does not work. Neither does removing/resetting the CMOS battery. How to successfully create a bootable USB-stick with BIOS update for CQ61-325ED?

Dell :: Studio 1749?

Jan 25, 2010

I believe '1749' is the model number for the core i5 Studio 17 - anyone know when it will be released or whether the i5-540m will be available? Considering buying an XPS 1647 now but would prefer the 17" screen

Dell :: Studio 1747 Vs. 1749

May 4, 2010

This is for the Dell USA site as of 5/6/2010....any other countries and/or times YMMV

There are some notable differences between the 1747 and 1749 being offered via the Dell Studio 17 selector

1749:

ATI 5650
i3-350M, i5-430M, i5-520M (No i5-540M or i7-620M. No Quad Core Options)
1066 memory (Makes sense since dual core i3,i5,i7's only support up to 1066 memory)
9-Cell battery as default option
1yr Warranty default
1080P "RGBLED" panel Description/Product Code = DH1080F / 320-8968

1747:

ATI 4650
i7-720QM, i7-820QM (No dual core options at all)
1333 memory support
9-Cell battery as default option
2-yr warranty default (No 1 yr option)
1080P "B+RG" panel Description/Product Code = CH1080F / 313-8043

Blue Ray RW drives are now an option for both @ $150.00
Intel 6200/6250 options are available for both

I'm definitely curious about the panel changes along with system board revisions to see if the 1749 supports Quad Core CPUs.

Dell Studio 1749 :: RAID Controller Or Not?

Apr 18, 2013

I have a Dell 1749 into which I have installed two OCZ Vertex 3 MaxIOPS SSD drives.  Boot times are pretty fast using a single, non-raid, drive but I was thinking of configuring the two drives in a RAID 0 configuration to boost speed a bit further.  I could not find anything in the bios settings that would allow the SATA controller to go to a RAID configuration.  I guess, therefore, that at least the laptop that I have does not have RAID capabilities.  Were there any Studio 1749 system boards that did indeed support RAID?

Dell :: Studio 1749 Fan Noise/temperature Problems

Feb 13, 2010

I've recently received my dell studio 1749 laptop with the following specs,

- i5 CPU 520m

- 4 gigs of RAM

- Intel HD graphics

- 320 gig HD

The problem with this laptop is that the fan will start to whine every few minutes seemly without reason.

I've done some investigation and found out the following:

- there seems be a threshold of 35 to 36 degrees celsius. Once the CPU hits that temperature, the fan will start to cool it down to under 30 degrees

- the idle temperature of the CPU is always creeping up, even without load. If I leave the computer alone at idle with almost no CPU activity, the temperature will creep up to the threshold...thus triggering fan.

the cycle repeats itself every few minutes.

I've attached a picture to illustrate the problem.

Since this is my first laptop, I want to ask does the CPU temperature stay constant during idle? or does it creep up like mine?

Can the threshold be modified?

Is this normal with the dell studio?

Dell Studio 1749 :: Extended Battery Life Gone

Jan 6, 2012

I had to reset my Studio 1749 to factory defaults and now the option for "Dell Extended Battery Life" within the Dell Battery Meter is gone. I don't know what needs to be reinstalled in order to get it back.

These are the changes that might affect the issue:

- Installed a different WiFi-Card (Dell 1520)- Installed a different Tuner Card (Yuan, provided by Dell)- Installed Service Pack 1 for Windows 7- Flashed BIOS to A08- Updated all Drivers and Utilities from the Dell Homepage except for the ATI-Driver

I think it is a useful tool if you use your notebook on battery, because it is able to control a few options that are not available in Windows 7 default power plans.

Dell :: Studio 1745, 1747, 1749 Backlit Keyboard Aftermarket?

I just bought a Studio 1749 with a Dutch US international keyboard. The US backlit keyboard is the only backlit one and not an option here.
The only difference is the missing symbol at key number 5, for which I don't care so much.

Now I'm trying to find the US backlit keyboard at eBay or Amazon without success. Is there a way to find one aftermarket and get it shipped to Europe?

Dell Studio 1749 :: Shuts Down Randomly Without Warning And Then Won't Start Back Up

Oct 19, 2011

I'll be using the computer and all of the sudden it turns off, it doesn't log off or say it's shutting down, I mean it literally loses all power. Then I try to restart the computer and you can hear the machine start to come on but then it dies again. I've tried charging it, I took the battery out and put it back in, etc. I'm just not sure what the problem is. I've only had the laptop for 1 year and 3 months and a few weeks before the year warranty expired the computer started to say that the battery life was coming to an end and so Dell had to send me a replacement battery. I've tried leaving the computer alone for days at a time and still nothing and of course it's no longer under warranty so I can't even call Dell without getting charged.
