Dell Latitude E5420 :: Getting Blank Screen On Boot Up Most Of The Times
Jan 16, 2015
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.

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?

Have a Latitude E5420 and the screen suddenly turn dark. Still can see a bit but sometimes will return to the normal for while. Is this because of the parts has lose? Should change the monitor? Or related to the driver?

I did a fresh install of Windows 7 Pro 64bit and have all the drivers loaded, I think, except one:
Mass Storage Controller
Can't find the driver, don't know what it is. I've installed the chipset driver, the ATA driver, etc. Still it shows as not found.

I am booting a Dell Latitude E5420 running Windows 7 and after the POST it just shows a blinking cursor..... BUT WAIT... not ALL the time... it does manage to boot into the windows after I choose the HDD from F12 options or sometimes even when I keep on shutting down and starting up again and sometimes when I do a restore checkpoint in the repair options....
The Diagnostic tests are not working when I go through the F12 and just hangs up showing the message -
Examining ACPI interface
Running MATS test
I can't understand... if it was consistently NOT booting or showing a consistent error... but here the behavior is erratic (except for the MATS test failure....

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 .....

Updating the BIOS for my laptop, full system crashes whenever I try running games [even low end].
Currently running A01, there are only two BIOS drivers up for download on the Dell site and both say I need to upgrade to A02 first.

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

My Dell Inspiron M501R will no longer boot up - its shows a black screen and repeatedly beeps 7 times. I understand this means the mother board has failed. The service tag is <ADMIN NOTE: Service tag removed per privacy policy> - its waranty has recently expired.
Interestingly, if you google "Inspiron M501R" google suggests "Inspiron M501R 7 beeps". So I'm guessing this laptop has been designed to fail soon after the waranty expires.
I have written a letter to BBC Watchdog asking how long a laptop can be "expected" to last and whether this would be covered by the UK Sale of Goods Act.

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 fitted a new LCD panel to an Inspiron 3520. Upon boot, it showed the Dell logo, then went all white and then displayed a grid made up of RGB pixels across the screen. I checked the panel was connected properly and the tried to reboot but now the screen doesn't power up at all. The laptop also now plays 4 beeps while trying to boot. I've tried connecting an external monitor, but it also does not display anything an plays the 4 beeps.

After change BIOS set up, the Acer 6920 cannot boot.
After turn on the ACER screen apperar with F2 (Bios) and F12 (multiboot) appear. If you dont press anything a black screen appear and stay there. If you press F2 or F12 the acer screeen stay with the "Please wait" message on it and stay forever. If dont press anything the black screen appear and stay there. Never got the RAM counting screen.
Looks like a BIOS problems so got the last version, put alone in a USB , put on the note and reboot with try every F key and every Fn+F key but never got a result.

I have an Inspiron 15R N5110. For the most part, my laptop has been an amazing machine, but not today. Now when I try and boot up my computer all I get is a blank screen and 7 quick beeping sounds.

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 have a Dell 4310 that I bought used without a hard drive. When I unboxed and initially tested it with another drive it booted into Windows 7, but, did not load because it wasn't the right drive.
The computer sat next to my chair for a few days until I got the new SSD drive that I wanted to install. When I put the drive in and plugged the system in (no battery yet) the battery light on the upper left flashed briefly and the power button came on and stayed that way for about twenty seconds. The screen remained black and the battery light and power button turned off.
This morning my son mentioned that he "might' have spilled a little bit of something on it. I quickly took it apart and carefully dried the pieces and parts on the heating vent and put it back together and the same thing happened.
I have tried the following:
1) Re seat RAM
2) verified video is connected
3) unplugged, held the power button for fifteen seconds and plugged the power cord back in.
What could I be looking at here, a new Motherboard?

I've got a dell Latitude D410; after it shows the Dell screen and the Windows XP screen (with the loading bar down the bottom), it goes to a screen with a blue background and a frozen mouse; after a while the mouse starts working but nothing else happens. I've tried booting from Last known good configuration but didn't work.

Well my HP dv6000 is still acting up.
Sometimes the laptop will not fully start/load. Meaning it never fully reaches the point when you can surf the net.
When it is not fully functional my mouse will not work when I click on IE or even the start button it can't activate them. It moves but does not activate any icons.
So I'll have to manually shut the lap top down by pushing the power button.
Next time it boots, It may not get to the point where the wireless is not up and running so I can't get IE to run it seems to fall short on booting to that point.
Then I have to hold the power button down to get it to reboot and start again.
Most all the time on the third reboot everything will work fine and run normally.
Time to reinstall my recovery discs and start clean ?

I really don't want to tear this laptop down & solder two leads to the 24c02 chip & short them together, even though I am A+ certified & an electronic technician.
This laptop has no service tag, old but worth saving because dim b has a 2gb stick of memory so, somewhere inside there's another & so it should be worth some effort to save.
The bottom line is: whoever designed that chip (24c02) is a genus, now how mush will it cost to unlock it ?

I'm having a problem with my IdeaPad Z585 laptop.When I boot it, it clicks exactly 16 times before it goes to a black screen. It does the same thing when I attempt a restart, but it will eventually restart normally after 10 attempts.

2 customers complained of very slow boot times 2-5minutes on these machines.
Removal of the Msata 24GB fixed it. I have asked them to check if express cache is installed but seems to be an ongoing problem.
What can lenovo do about this? Will replacement of the Msata drives fix the problem or is there a bios update coming which can remedy this.
