Lenovo X Series ThinkPad :: X1 Carbon Startup Blank Screen And No Activities After BIOS ACHI To Compatibility

Feb 12, 2014

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

I have a Dell Inspiron 9400, I think thats the same as an Inspiron E17-- in america (for some reason dell likes to confuse its customers).

My screen goes competely blank after the dell logo and windows logo show up on startup.

Apple :: Macbook Pro - Blank Screen On Startup

Oct 3, 2009

I've got a late 07 macbook pro with those faulty 8600 nvidia gpus. My macbook pro was working fine last night and now this afternoon its got a blank screen upon startup. I can still hear the chime and it still boots into the OS as i can still change the volume and backlit brightness etc.... Is it confirmed to say that my luck has ran out and the GPU is dead?

My warranty has expired and have no extended applecare + I bought the macbook in one of those education apple store. Will I still be able to get the free repairs as stated by apple and even if I do, won't they still replace the logic board with another unused faulty one and down the track my macbook pro will still be prone to that same failure?

Lenovo B / G Series :: G510 - Can't Undo Display Changes Due To Blank Screen

Jun 17, 2014

Lenovo G510 laptop; Windows 7
I'm trying to set up the laptop to use an external monitor via HDMI. I tried a setting but it didn't work. However the laptop screen went blank and now I can't undo the changes.
On reboot, the screen works until the Window splash screen then it goes blank as the computer continues to boot up.
Booting into safe mode works, but I can't access the graphics card properties from there.
Tried unplugging the HDMI cable, but doesn't work.
How can I bring back the default display settings without doing a hard reset? (It's not my own computer)....

Dell Inspiron N7010 :: 8 Beeps On Startup And Blank Screen

Dec 7, 2014

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.

HP Pavilion G4-2149se Lockups :: Blank Screen And Cursor At Startup On Notebook

Aug 23, 2014

I have an HP Pavilion g4-2149se Notebook running Windows 7.For the past 2 weeks almost, whenever I start my computer, before getting the Windows welcome screen, I get a lingering blank screen with a cursor. Then, it'll finally get to the welcome screen, but before it loads my desktop, I'll get another lingering blank screen with a cursor. Honestly, I'm grateful that my computer is still starting up at all... But is there any way to fix the lingering blank screens? It's making me nervous.I've looked around the web for a solution for days, and anything I could find I've tried, but nothing has worked. I uninstalled all recent Windows updates, hoping one of them had went wrong, but no luck I scanned for virus' and malware and found nothing. I've only downloaded one program since I noticed the problem began (4K Video Downloader), though the program doesn't seem to be a problem.

Dell Inspiron N5010 :: Blank Screen At Startup (External Monitor Also Didn't Work)

Oct 7, 2012

I have an issue with my Inspiron N5010 screen, it doesn't work when switching on my laptop on Battery or AC mode. It happens a lot of times when I turn on the laptop the power button, the power indicators at the bottom turns on normally and the laptop is running without any weird sounds. But the screen is pitch black even doesn't show up anything when I concentrate on it in with a lamp or any light.

When I press the power button again even after 5 mins from the start time of being running the laptop just turn off immediately and doesn't take time to switch off as If the windows wasn't loaded!

I was resolving this problem by disconnecting the AC adapter > removing the battery > Pressing and hold the power button for 20 seconds technique.but today it doesn't work anymore, If there's anything I can do to get the screen backlight to work normally ....

Lenovo T400 / T500 :: T430U Not Booting - Blank Screen Or Never Gets Passed Splash Screen

Nov 25, 2014

System specs:
Lenovo T430U
Intel i5-3427U
8GB PC3-12800 DDR3-1600MHz SoDIMM Memory
HDD 500G 7200rpm Toshiba
mSATA 24GB Samsung Cache
Win 8 Pro, upgraded to 8.1
I rarely use this machine but a couple of months ago I went to boot it up and found that I was not able to get past the Windows splash screen. Sometimes I don't even get the Windows splash screen, I just get a black screen. Rarely I get a Windows screen saying that it is diagnosing a system problem or something to that effect and I can even get to where it will allow me to do some Windows diagnostics but nothing ever comes of it and the process is extremely slow.
I called Lenovo, but of course my machine is out of waranty so the tech just gave me a few pointers and said I could send it in to the depo but the potential repair cost could range up to about 75% of what I paid for the machine in the first place. Anyways, after having me try a few things in the BIOS he suggested that it was likely the hard drive. I mistakenly thought from the time that I bought this machine that the OS was installed on the 24 GB SSD so I ordered a new SSD and swapped it in. This made no difference at all as I have now learned that the mSATA SSD drive is merely for cache to speed up booting.
I am afraid that this means the main HDD is at fault, and quite frankly, if I replace it I am going to do a fresh install of Windows 7. But I do have pictures and docs that I would like to salvage if possible.

Lenovo P/Y/Z Series :: Y510p Freezing On Startup

Apr 9, 2014

My Y510p has been freezing on startup, every startup. It can be completely inoperable for upwards of half an hour before unfreezing. It unfortunately has been occuring since the computer arrived (21 March, this year), so I doubt it has been caused by any software I've added. Given my limited knowledge of computers.

Lenovo Y510p Model 20217
Windows 8(64 bit), Intel Core i7-4700MQ CPU (2.40 GHz), NVIDIA GeForce GT750M, 8GB RAM

Lenovo Y510p P/Y/Z Series :: Keeps Turning Off After Startup?

Sep 24, 2009

my y510p is 5 months old, it's the non - SLI version, installed Win 8.1., warranty still valid. Today I worked on my notebook as usual, listened to some music and it suddenly turned off. It was connected all the time to the charger.

I tried to turn it on several times, everything seemed fine, the keyboard lights up and the LCD shows the normal Lenovo startup screen, but after 3-5 seconds notebook turns off. The OKR works the same way - the menu is shown for a while and after about 3 seconds my notebook turns off. No BSOD, no any other supporting symptoms. Tried to enter BIOS, it worked out, but the computer still turns off after few secs in BIOS.

I thought the reason might be too high temperature, but the notebook was almost always slightly warm, never hot and the cooling fan was running pretty quiet. My computer never fell off or was hit or anything.

I heard computers run a self-test before start. Is it possible that some component of the notebook can't pass the test?

Lenovo ThinkPad L R/SL :: Blank Screen After Memory Ram Changed - SL510

Jan 3, 2012

I had  1GB & 2GB rams working fine in the SL510,  windows 7 Profession, 62-bit, 320 GB drive. SL510 62-bit can take up to 8GB ram.

I replaced the 1GB  by Samsung with a Hynix 4GB.  At Crucial they give specs that are replacable for existing ram.  I notice one number is different.  The original Samsung says PC3 -10600, and the new Hynix says PC3-12800.  The 12800 was given by crucial as part of the replacement numbers for the SL510.  I bought at EBay used.
Anyway, I bootup and a blank, black screen results.  I hear laptop running.  I forced closed it and re-started again.  Same...black screen as I hear laptop running.
Also, is there a certain order for rams to be installed?  Originally, the 1GB ram was first, and the 2GB was below.  I installed the 4GB ram below and moved the 2GB to top first position. (in case I want to access the 2GB easily to upgrade with another 4GB)

Lenovo X Series ThinkPad :: Windows 8.1 Fast Startup On X220

Nov 21, 2014

Having some troubles with my X220 and windows 8.1 and fast startup.

It has been working flawlessly for a few months now with Windows 8 and an SSD but has recently decided it does not want to fast startup - every time I try and boot with the feature enabled the laptop immediately shuts off completely after the boot animation. On pressing the power button again the laptop boots 'normally' i.e. at 'normal' startup speed.

I've tried disabling the feature, using the 'powercfg -h off' and 'powercfg -h on' commands to recreate hiberfil.sys and enabling it again, which worked at first but now it has started having the problem again and this no longer works.

Lenovo X120e X Series ThinkPad :: Bluescreen On Windows Startup?

May 15, 2014

Recently, my x120e began blue-screening (with error code c000021a)  while Windows was starting up. However, if the computer was off for a period of time, usually about 5-10 minutes minimum, it would start up with no problems. I thought it might be overheating except for two things:

1) Once windows started up, I had no issues. No matter how much processing power I was using, it didn't bluescreen or even try to turn itself off

2) When I rebooted in safe mode and looked at what modules it was loading, it always failed after the same one (CLASSPNP.SYS)
I had heard that there were occasionally some significant driver issues with my hardware, so I did a clean re-install of Windows (Win 7 Pro, 64-bit), hoping that this would rule that out.

The issue persisted, and in fact would interfere with a Windows install disk booting into the installer. After I got the installation to complete, the previous issue continued to be present.
I did some Google searching and found that the BSOD error code c000021a is generally caused by a driver or security issue, and the usual solutions suggested are to try to use the "Last Known Good Configuration Option" for windows startup, and to update drivers. However, neither of these things have worked, as it still does this on a fresh Windows install.
I also tried running without the battery (AC power only) and without the AC power (battery only), and neither has fixed the issue.
(Side note: This was originally happening with the original 320GB hard disk that came in the machine. I was going to upgrade to an SSD anyway, and this problem has persisted with the new drive).

Lenovo B / G Series :: G500s Hung At Startup And Can't Access BIOS

Sep 11, 2014

I have a problem with my Lenovo G500s  1.1 years (1 year & 1 month). It worked perfectly until last month. It started to freeze. I restarted the computer (btw I was using licenced win8 back then) and then the lenovo logo showed up and it stuck there. I was waiting for about 10 minutes, but nothing happened. I turned it off manually, and then turned it on,it was still frozen. after some trial of startup,  it worked normally. After 2 days it happened again. I thought it was the system, so I deleted the windows8 and installed windows8.1 licensed, it worked for a month and then again (last night) it just freezes at startup (lenovo logo shows up). Till now its frozen. I restarted it several times, it didnt work. I also pulled out battery & started on AC power which didnt work too. Obviously, i dont have warranty.

Lenovo P/Y/Z Series :: IdeaPad Y580 Shutdown And Fast Startup

Oct 27, 2013

I have a problem with shutting down my computer. While it seems like the system is closed and the screen goes black, the laptop is still working (power button still glows white and ventilators are on). The only way to shut it down completely is by holding the power button for 5 seconds.

My specs are: Intel Core i7-3630QM, 1TB HDD (560GB free), 16GB SSD, 8GB RAM, NVIDIA Geforce 660M

In last month my laptop used to be working for 4-5 days in a row, and only today did I notice that it won't shut down. I did some research and found out that the feature called "Fast Startup" is responsible for this - disabling it with Energy Management resolves the problem, and the laptop shuts down nicely, while re-enabling it makes the problem return.
I also found out that the Fast Startup feature (while enabled) creates(/modifies?) a file called "hiberfil.sys" which stores data about my current session and then shuts down the laptop completely.

So apparently there is something wrong about this file or the process of creation/modification of it (I'm not sure how it works) when I try to shut down my laptop. Or even it might be not about that file, but some 3-rd party process which blocks the creation/modification of it?

So my question is what can I do to solve this problem withoutdisabling the Fast Startup feature (I mean disabling it costs me like additional 40 second during turning my computer on, which is not much, but the pure fact that I have to disable this means I have some problems with my laptop).

PS. I ran the "powercfg.exe /hibernate off" command, restarted the laptop, then ran the "powercfg.exe /hibernate on" command, in hope of clean-creation of hiberfil.sys file, but it did not work (maybe there is a way of manually deleting it in order to automatical re-creation of the file during the next shut-down?).

The only thing on my mind now is leaving the laptop "shut down" for a night - maybe that file is so large it needs a lot of time to be created/modified, but that wouldn't explain why shutting down my laptop in the previous 7 months has been taking only like 5-7 second, not the whole night.

Lenovo T400 / T500 :: T410 Won't Boot / Blank Screen And Keyboard Unresponsive At Power Up

Dec 23, 2014

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.

Lenovo ThinkPad W Series :: W530 (To Interrupt Normal Startup - Press Enter) Not Working

Jun 24, 2013

My W530 displays the "To interrupt normal startup, press Enter" message on startup.  If I press Enter, I hear a beep and a message comes up indicating that a menu will be displayed, but Windows 8 starts loading shortly afterwards.
When I see the message, I can press F1 to get to the BIOS, F10 for Diagnostics or F12 for a Boot menu, but for some reason enter doesn't work. 
I've tried several things, including using Recovery DVDs received from Lenovo to wipe the system (including formatting all drives), but still no luck.
When I originally received the machine, the "enter" key would bring up a menu, but I have screwed something up and even a full recovery from Lenovo DVDs didn't work. I run Windows 8 and after receiving the machine used the Create System Image feature (which I had used many times in Windows 7), but a subsequent restore didn't go well and that is when the "enter" stopped working on startup.
