Dell Latitude E6530 :: Blank Screen At Power On After Switching BIOS To UEFI Boot
Aug 7, 2013
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?
I have a new dell latitude 6510 notebook and now i will install Windows 7 Pro 32 Bit again. When selected "Boot List Option" under bios settings i see legacy and uefi but i can´t "Add Boot Options" - Warning "File System not Found". Windows 7 Pro 32 Bit is installed and working under legacy but not working on uefi. When uefi selcted windows 7 pro 32 Bit is installed and when installation is finish can´t find bootable device.
The laptop wont turn on when its plugged in it says it's charging then when i attempt to turn it on it sounds like its booting up but within about 3 seconds it shuts off without the display ever turning on the LED light showing the battery is charging then begins to flash and the other 2 LED lights stay on. I was on the laptop not even an hour before this happened until it died and it hadn't moved after that so I'm not sure whats causing the issue.
I am having some real issues with a Latitude E5420. It will sometimes boot no problem, maybe 40% of the time.
Most of the time it goes to the dell splash screen and the bar goes to the top then i get a blank screen. No blinking cursor or anything. No HD activity, no CD drive activity.
I can press F2 and get in to the bios, i can press F12 and get to the boot menu but even after selecting a boot option from the boot menu i will still get a blank screen most of the time.
Once the Laptop boots up it runs fine and doesn't report any errors. A memory test has shown no errors. I have replaces the CMOS battery, which was a bit of a nightmare, i have replaced/swapped the memory modules.
who has an E6530 with BIOS rev A07 test to see if the 'Custom' charging mode functions properly via the Battery Information application that is installed with the Dell Feature Enhancement Pack ? The Battery Information application worked properly prior to the A07 update.To test:
2) At the DELL logo press F12
3) Select 'BIOS Setup' from the pre-boot menu
4) Select Power Management, then select the 'Primery Battery Charge Configuration'
5) Select the 'Custom' option (Write down which option is selected before you make the selection so you can restore this setting later)
6) Set the 'Custom Charge Start' value (e.g. 50, NOTE the BIOS will not allow a value less than 50)
7) Set the 'Custom Charge Stop' value (e.g. 75, NOTE: the BIOS requires this value be 5 greater than the 'Start' value)
8) Click 'Apply', then click 'Exit' and let the system boot into Windows
9) Launch the Battery Information application by performing the following steps: 9.1) Press the 'Windows' key 9.2) In the 'Search Program Files' search box type: 'Dell Battery Information' 9.3) Click on the 'Dell Battery Information' link in the search results
10) When the Battery Information applications starts, verify that the Charge mode displays 'Custom' (see figure )
11) Click on the 'Change Setting' button
12) Verify that the 'Custom' mode is not listed (see figure)
13) Verify that the 'Start' and 'Stop' values which are set in BIOS are NOT correctly displayed, and that you are unable to change the 'Start' and 'Stop' values.
14) Restore your charge configuration by selecting the Charge mode you wrote down in step 5
my Lenovo T410 laptop won't start. I hit the power button and it looks like it's about to boot up. The thinklight blinks on as normal, the cd drive is checked, the caps lock button blinks on, then nothing. No display, and keyboard is unresponsive. Power light remains on; if I leave it a while the fan comes on. I can turn the machine off using the power button, but the problem remains next time I switch it on.
I've tried removing power and battery, pressing power button 10 times then holding power for 30 secs, before replacing power and battery, but nothing happens. I've tried using a different keyboard. I've tried plugging in an external monitor. No change.
This problem appeared after I left it on overnight. I have a hunch that it went into hibernation mode, perhaps, and that it disrupted some important function which it was unable to complete.
I got a Acer Aspire 4315 for Christmas this year....
It has been running great , on Vista, untill recently....
I have 2 problems:
1.... When switching on sometimes i get a blank white screen....? I can hear it swithing on, the fan spinning and the windows welcome noise but NO SCREEN! What is going on? This also happens at random times, sometimes i think its when it gets too hot?
2..... My Ac adapter, power suply... When left on fora long time gets very hot? I understand that this is normal... But why does it make a very annoying high pitched noise?
When I pull the power cord to switch to battery power while in Windows my lcd goes to black. The only way I get my video back is a hard reset and reboot. Later on I tried this and everything was back to normal. Why is this happening? Is this some weird standby?
I bought a ThinkPad 540p that comes with preloaded Windows 8.1. As I want to dual boot the machine I tried to select the Legacy Boot option in the BIOS/Startup tab, but I can't do anything as the option UEFI/Legacy Book is greyed out and locked in "UEFI Only". Below it there is an option called: -CSM Support that is also greyed out and selected as [No]. (below these options there is a little note with an asterisk saying "Unselectable for Secure Boot").
How can I enable the UEFI/Legacy Boot option again in order to dual boot the computer? I want to be able to boot from USB or from the CD Drive.
I have a Dell Latitude D800 that will not power on. When the power button is pushed the green power indicator light comes on, the CDROM spins for a moment, but then nothing happens, there is no BIOS information displayed, no power on self test, no Dell logo. It just sits there with the green power light on.I have tried removing the power & battery then pressing the power button for 10 seconds (actually, I have tried as long as 60 seconds). I have tried to turn on with the power connected but not the battery. I have tried removing the connector cable for the power button and the connector cable for the display and then reseating them.
For me it happens when I shut the laptop screen and open it again right away. If I wait a few beats before I open it, the screen lights up again just fine.
But if I open it right away after closing it, the screen goes blank, though the laptop seems to be running just fine.
Hitting Fn-CRT/LCD does nothing, nor do any other of the function keys. I even tried hooking up an external monitor and banging away at the CRT/LCD combo, but the external monitor is just as blank as the laptop LCD.
Hard power-down will restart the laptop and the screen comes back fine, but you've lost any unsaved work .....
My studio xps 16 screen appear to be blank and refuses to start up when i powered the machine. I waited and it does nothing, other than maintaining the light on the keyboard and touch sensitive area at the top of the keyboard....
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 have an Aspire 5610 with 2G ram running vista home premium. I had a few explorer windows open, and was getting memory warnings. I shut a few windows down, and a few hours later, the screen turned blank. I reboot the computer, but the problem persists. Now it turns out if I remove the power supply, and run it on battery, everything is fine. As soon as I instert the power supply chord, screen goes blank (black). Upon removing the power supply, if I shut and open the screen, it works again (and it also shows me a warning message that the wireless is in use, and if I really want to turn the antenna off).
The screen obviously is fine, as it runs fine on battery. I don't understand what is happening as soon as I insert the power supply, and why upon removing the power supply, I get a warning on turning off the antenna.
My work computer will flicker, go blank/black and sometimes I can tap on the battery or the hard drive and it will come back. Sometimes (more times than not) it will require a total reboot. Lately it won't even load. It will load the Dell screen then it says Starting Windows the logo comes on then it goes black. It still loads and everything but I can't see anything. I've replaced the hard drive so I know it's not that. I've loaded the computer in safe mode and I have NO problems with it when it's in safe mode, only when it boots normal. I tried the FN+Power but nothing happened when I tried that the numberlock LED is the only one that stays lit, the others didn't start flashing or anything
I have got a Latitude E6530 laptop with an Intel quad-core i7-3720QM CPU and 8 GB RAM.
The strange thing is when I use Firefox (with not more than 6 tabs) specially using gmail, after a while scrolling and browsing become very slow; even typing become slow. As I wrote the laptop is one of the latest generation. I can not realize where the issue could be.
2 days ago I had trouble accessing the internet on my E1-570. Windows Explorer kept throwing up a fault and restoring the page. Eventually I loaded Safari and then Firefox and resolved to sort the problem with Windows Explorer some time in the future. This may be unrelated to what happened the next night. Started the E1 and got the usual "Acer, Explore beyond limits" screen and spinning dots, then got the login screen - input password then return. Spinning dots for much longer than usual then blank screen. I can see the cursor arrow so the screen itself must be functioning. Lights on the front are working - AC, battery and HDD. I have had the machine 14 months and it is used exclusively at home so has not been roughly treated.
I got a Latitude E6530 with an E-Port II a few weeks ago. In general it's great but I have had one annoying problem a few times:
The laptop is docked with the lid closed, and two external monitors, and an external USB keyboard and mouse connected. It's running Windows 7 Ultimate.
The laptop goes into standby after a few minutes of inactivity.
When I press the power button on the dock to resume from standby, the external monitors stay in standby mode and the mouse and keyboard don't power on (no num lock light or laser on the bottom of the mouse).
If I undock the laptop and open it, the screen stays off and it doesn't respond to keyboard or touchpad input, even after several minutes. However the power light is on and the hard disk light occasionally blinks. The only solution is to power off the laptop by holding the power button for a few seconds.
Note that this doesn't happen every time that the laptop is woken from standby, it's only happened 3-4 times in a month. The Windows logs don't show any errors either.
I have a Latitude E6530 and I'd like to upgrade the resolution to 1920x1080. What cable and LCD part # (or compatible) do I need? The panel is easy enough to replace but I have no idea about the LCD cable.
Using Dell Clent System Update to update a Latitude E6530. All drivers are updated now except the Intel Chipset Driver. On Windows 7 64 bit. Framework version of the driver is 3.0.921.
The error message that it gives is Update package digital signature is invalid - status: Failed Error Code 7
Not sure how to remedy this.
I am trying to install this driver update hoping it will remedy a black screen with cursor when logging in. It takes about a minute to login and then the desktop finally appears. Was taking quite a bit longer to log in before I updated the other drivers and then removed McAfee to see if it was eating up system resources.
I reimaged my client's laptop and I am trying to download the drivers for the Universal Serial Bus Controller. I went on the dell website and tried downloading it but it still shows up as missing.
Operating system: Windows 7 x64
I was also wondering if dell has put the correct drivers up for the operating system. I select Windows 7 x64 drivers on the webpage. When I try to install them, it gives me a "invaild operating system" error.
I was recently given a Latitude E6530 and I wish to upgrade the standard keyboard to a backlit one after coming from a MacBook Air. I was wondering, does E6530 (or it's similar models) requires an additional cable to power the backlight or does it just feed off the single cable? I've scoured YouTube and Google to try find out if an extra cable is required for this model however wasn't able to.
