Dell Inspiron 5720 :: Updated BIOS From A13 To A14 - Blank Screen
Jan 29, 2013
A couple hours ago I updated my BIOS from A13 to A14. The firmware update took successfully and everything was fine, I THOUGHT.
Now, every single time (not exaggerating) that I restart my computer the Dell Circular logo pops up for maybe half a sec, and screen goes blank. Lights on laptop do it's thing, I hear the dvd-rom set itself like usual but like I said, no loading ring under the Dell logo appears, the screen just goes blank. All I have to do each time is simply push the power button till computer turns off, and turn it on again. The second time around it works completely normal and loads into Windows.
This happens every time I do a restart from windows, a restart from BIOS settings, or if I turn the computer on after it's been off for a couple minutes. The Dell circular logo appears for maybe half a sec, than screen goes blank, I wait forever and it does nothing but all I have to do each time is push the power button, let pc turn off, and push power button again and it works until the next system restart and it does it all over again.
Won't be too much of a problem but it's aggravating that every time I restart the computer I just know i'm going to have to wait for the blank screen and push the power button to turn it off and back on.
All drivers were fully updated before I performed the BIOS firmware update from A13 to A14. Update took successfully.
I unplugged laptop, and took out battery for a little while to clear my RAM, but that did not fix the problem.
I always loaded BIOS setting defaults, still have the problem.
I have no CD/DVD in the ROM, nor do I have any USB devices, memory cards, or blue tooth device hooked to the computer.
Inspiron 5720 (all drivers updated)
BIOS Version A14

CPU is i5 3210m
Ok, so I have this laptop (17R 5720) that I got in November. Um every time I turn it on, I get a blank screen just after the dell logo pops up.
I've tried taking out the battery and unplugging the adapter and holding the power button for 30 seconds and putting the battery back in. I've tried "D" + power, tried Fn + Power, tried F2 to get to the BIOS window, and I've tried F12 (which only got me to the Boot menu). Still nothing happens.
Don't know what else I can do. It looks like I only got limited access to technical support so I hope it's nothing major that I have to deal with.
Because I had a minor problem with my laptop (since a couple of weeks it was always starting up in manufacturing mode) I decided to update my BIOS.So I downloaded the BIOS-update A19 (currently I was running A11) and followed the instructions to install it (power plugged in, shut down all applications, removed all peripherals).
Everything seemed to go fine: the computer restarted, came in BIOS and did all update tasks, but then at the point that normally Windows should start. I got stuck on a black screen and my fan blew at maximum speed.I left it running for about 5 minutes in the hope it would come back but it didn't. So I decided to try to shut down the system. This was not possible by holding down the power button. The only way was removing the power cord and battery.But after this incident my laptop is completely death. Does this mean the motherboard is completely wasted?Because I’m out of warranty it is not even possible to open a support request for it on the Dell support site.
I have installed Windows 7 Ultimate SP1 on my laptop after upgrading fom A08 to A09. At first my batter did not charge at all , so i got it replaced with a 9 Cell one. But it would only vharge till 69%.
I tried all the way on internet uninstalling drivers, removing battery, draining it out etc. Still no chnage. Lately it is now charging only till 33% .
Now i Plan to go back to Vista Home premuim just to see if the battery charges fine. My question is do i also downgrade the BIOS or should i check first if it works fine in A09 and then install A08.
My Inspiron 17R 5720 laptop (which came with windows 8) was working fine yesterday but whenever I try to turn it on today it shows the Dell logo briefly then goes to a black screen and remains like that. The F12 key works, but I can't change any settings as it will only let me highlight the diagnostics option. I've run diagnostics and recieved no error reports. Neither the F2 or F8 keys work, so I can't access BIOS or start in safe mode. I've tried removing the battery and unplugging the power.
Tried (and sometimes successful) to connect HDTV to laptop, Inspiron 5720. Now laptop screen does not display (goes black) without an external monitor physically attached. Tried using Projects and clicking on single laptop display, but if I disconnect the external monitor, the laptop screen just goes black. Not very portable if I have to lug around a second display.
My laptop is having problem actually when i start my laptop different colored horizontal line start coming on screen and after some time whole screen becomes white.. what is the reason behind it and what is the solution of it...??
I have a Dell Studio XPS 13 (1340) and when i switch it on the power lights etc come on and the screen is blank. After a while it shows the Windows desktop and the laptop is ready to use but I cannot see the DELL logo at start up or am I able to get into BIOS. However when I plug the laptop to an external monitor it displays the LOGO properly and I am able to get into BIOS.
I'm trying to install Ubuntu on an e6530. I changed a BIOS boot setting from Legacy to UEFI. Now the laptop doesn't even show me a BIOS screen at startup. The screen is backlit, so power is on, but shows nothing. The drive light flickers a few times, but no matter how long I wait, nothing appears.
I can't even switch it back to Legacy because I can't get into the BIOS. Hitting F12 after power on does nothing. Is there some way to get it back to Legacy mode? Or simply reset the BIOS to default settings?
Her mum was using the laptop a couple of nights ago and the screen just went blank suddenly when she was browsing the internet.
She held the Power button in and turned it off as it was still running. When she tried to Start it up again the Laptop is starting up but nothing is coming up on the screen, The screen is staying completely blank,
Although when you hold for talk sake the Light of your mobile phone around 1cm away from the Screen you can see the Desktop of the Laptop. So basically the laptop is working but theres no light to light the screen up it just stays black as if it isnt turned on.
Whenever I switch on my Inspiron 6400, either via the On/Off or Media Direct button, the screen almost always goes blank within less than a second. I would like to reset the computer to its original factory settings via F8 or reinstall the operating system via F12 but cannot do so because of the blank screen. Occasionally, I hear the sound which accompanies the window screen a few seconds after switching the computer on; the computer will also sometimes whirr and the number lock and wife symbols will illuminate, all whilst the screen remains blank.
This problem first developed yesterday when I received the message "NTLDR is missing". With a bit of perseverance yesterday, I could eventually get the computer to work by repeatedly switching it on an off, but this no longer seems possible today.My computer has Windows Vista.
I have a X1 Carbon 3443CTO and it's running fine.Last night everything was ok and I went into the BIOS and changed AHCI to compatibility (don't ask me why, I was doing some testing), then I went "Exit and Save Changes" (at the last page of BIOS). As soon as I press Enter the screen freezed there (as opposed to reboot)Since it hangs there I hold the power button and it shutdown.Then I power it up again, but now, here is the problem:
1) The computer turns ON, keyboard backlight flash on for a second (normal) 2) Screen stays blank (no, it's not the backlight faulty) 3) power light turns ON (normal) 4) no sign of activities pressing any buttons, no beep sound
My Dell Inspiron 1526 won't restore after hibernation.
After a recent Vista update the laptop was placed in hibernation mode before the normal 'restart to complete update' process. After a minute or so i press a button expecting to see a logon screen, instead the monitor was off, blank screen with no power.
I presss every button but nothing happened. After a restart the monitor remains off but i can still hear 1526 checking the cd drive. I restarted several times trying the Fn+F8 option with an external monitor and pressing the up button while holding Fn but still the same.
1526 appear to be in a wierd state because i placed a XP boot cd and restart then hit Enter several times. If the backlight or inverter was the only problem then 1526 would boot from the cd as normal though i wouldn't be able to see. It doesn't, it simply power up, checks the cd drive then does nothing.
Just two days ago I was using my laptop then turned it off like any other day. Later in the day I proceeded to turn it back on and received the dreadful 7 beeps with a blank screen. For the time that I've had it, I've taken good care of it, (never dropping it etc.) I have read on some of these forums that the 7 beeps could mean a bad motherboard/processor.
I'm having problems with my inspiron mini,when I am turning laptop on I'm only getting a black screen,the LED light is on.after researching online I have tried several methods 2 get it 2 work but still getting nothing...
I have an Inspiron 15R Windows 7. Set default power setting "Ballanced" but screen goes blank after 1 minute and 5 seconds not moving my mouse or depressing keyboard key on both battery power and plugged in. Screen should remain on 5 minutes on battery and 10 minutes plugged in. Tried resetting default power settings without success. Very distracting when trying to read anything that takes longer than 65 seconds.
My Inspiron N7010 was working fine until 2 days ago. I had it playing a movie through the HDMI port to my TV & then the video started to freeze up. Starting the next day, when I tried to start it up, it beeps 8 times & goes to a black screen, then eventually it turns off. I opened it up & re-seated the CMOS battery & checked all the ribbons. Tried holding the "d" key while powering on, the screen cycles through the colors & then goes black & powers off. Tried connecting to 2 different external monitors, could not get a picture on either.
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.
I'm facing the similar issue on my laptop Insipiron15Z 5523.
Before the issue got popped up, i was ran into waves in the screen and it was persisted for more than a minute so i thought of something went wrong and made forced Shut down by long pressing the power button.
Enclosed the image for quick diagnostics.
Then again i was attempted to switch on my lap,following odd things happened.
1.After switching on, LED lights of Power button,favorites,Music were flashed - usual - nothing got worked.
2.Not got any response, after sometime i heard long beep sound at equal intervals without gap.
3.Beep sound never shuts down and i press the power button in single stroke,machine got switched(not long press)
4.Next time i was attempt to run for diagnostics mode like pressing the F2 & F3 button,no use.
My Laptop is non responsive and am not getting any indications on my screen.
I have an almost 2-year-old laptop with which I've been having problems for the last week or so. It all started when after hibernating the computer had a blank black screen not responding so I shut it off. After that it seems to boot up only once every 20 or so times. What happens after I press the power button: The laptop starts booting but doesn't get to the dell startup screen, after a while (after booting 3-4 times unsuccessfully) the fans even start spinning but the screen stays black and the hard drive light indicates that the drive isn't working.
LED Lights: The first light turns on, the second light turns on for a second or two (indicating hard drive starting to boot up) but then the light turns off and the computer is still running, but nothing happens. The third light is fine, there is no problem with the battery or the power supply.
I've tried reseating the hard drive, the RAM, removing one stick, then the other etc. and nothing works. The strangest thing is sometimes (very rarely) it does work, so far it booted up 4-5 times (if it gets to the DELL startup screen it's fine), but the rest 85 times it didn't .
For the past several days, when I've first opened my laptop there is only a blank screen. The computer does not wake up even after I push the power button and the screen continues to be blank. The only way that I've gotten it to respond is by shutting off, unplugging, removing battery and then replacing battery and turning it back on again. I've done this in different combinations. Do I need a new battery or is something else wrong?
