How To Fix Lenovo G560 hang, BSOD, and hang at POST

TIP: You should click here to fix Windows errors and optimize system speed.

Blue Screen of Death BSOD is a stop error screen that is being displayed on a Windows computer every time a fatal system error or a serious system crash occurs. This is the time when the operating system can no longer work and operate safely. Blue screens usually gives out a stop code which users can use to determine the root of the problem.

Generally, blue screens are a result of an issue with the computer hardware or its driver software. Low-level softwares can also cause the system to crash and trigger a BSOD. However, regular apps and programs can not cause BSOD if they crash.

Windows automatically makes a “minidump” file when a blue screen arises. This file contains details about the crash that will help identify the main cause of the blue screen error.

From the Forums

A user in the forum details it further:

Maybe try removing the Intel driver,and let Windows install a driver.Then see if it happens again.And you should call Lenovo support I think. Eventually it will BSOD, the exact message I do not remember but something like a 'system process or thread failed to run'. Purchased and Lenovo G560 in July and so far this has happened 3 times:The system become unresponsive, the hdd activity light goes out or stays solid, Windows programs crash and no other programs will start. It also is using the latest drivers for other devices from the Lenovo website or intel website.This has happened with 2 differnt harddrives, both function perfectly fine in other machines.

Should I return this ASAP? The hanging at post seems to suggest this but it happens so infrequently and I can't reproduce it at will. I've run memtest and swapped out the RAM with other sticks.

The crash dump fails to write to disk and it reboots and hangs at POST. Hard powering down and powering back up lets it boot fine.At first I thought it was a bad intel rapid storage driver, but I am now using the latest one from the intel website and it occurred today. I am using the latest BIOS for this machine and it is a relatively clean install of Windows.Is this likely a hardware issue?

What causes Lenovo G560 hang, BSOD, and hang at POST

To fix a Blue Screen of Death error, you need to take note of the text on the screen when it happened. It often contains a list of files associated with the crash including device drivers that could have triggered the error. Since most Windows are designed to automatically restart after a blue screen, you need to make sure that you disable this feature in order to do any necessary troubleshooting in future cases of BSOD.

One most important thing to do after a blue screen is to ask yourself what you did before it occurred. It could be that you are trying to install a new software, updating a device driver or installing updates - the key is there. You can also check your storage and make sure that there is enough space for Windows to operate safely. You can also set hardware settings and BIOS to default to help troubleshoot the problem.

Boot up Freeze/Hang (PROBLEM!): Lenovo Updates Hang T61

I installed Norton Ghost  yesterday and the same problem happened again.

I recently updated my system with the latest Lenovo Updates including a BIOS update. The hard drive then stops loading and the laptop freezes.

It's not a hardware issue with my laptop because when I don't do the updates and or install certain programs, my laptop does not freeze on boot-up. Then my computer booted but all I got was a wallpaper my Windows Vista black bar and 3-4 icons loaded on the left tray. I think it might possibly a Lenovo software issue or a BIOS issue. Is there anyway to revert back to my old BIOS?This is what happens when I do the Lenovo updates or install programs like Norton Ghost: Computer boots up, loads wallpaper and Windows Vista Black Bar, about 3-4 icons load up on the tray on the left hand corner then the hard drive stops loading and everything freezes.The computer works perfectly fine when I don't install those updates or install Norton Ghost.

I recovered my computer to original the factory settings and it booted up perfectly.

BSOD/ Post login System Hang/ Explorer.exe Crash

Well recently it crashed, gave me the BSOD. Thank you for looking, I appreciate whatever feedback you can offer. From what it looks like to me, it has something partially to do with my processor. I don't have much of anything on start-up because I prefer to have it start-up and choose which programs I want to run when..well you get the picture, anyways.

Maybe my chipset, i'm not sure, which is why I'm posting here.

Hey, New here, had this problem for quite a while (been using win7 for over a year with this hardware setup.)

Well so basically, a few weeks after a fresh install (reformat every 3-4 months usually just a personal preference), it starts to hang after logging in. Its about time for a reformat, but I would like to see if I can solve this problem. If you need more information let me know.



I'll also include the events the day of it BSOD. System Information:
Asus m4n98td EVO mobo
AMD Phenom II 955be (not overclocked)
8gb ram Corsair XMS3 1333mhz dual channel
Asus nVidia ENGTX 560ti 1gb OC edition
Western Digital Blue 320gb hdd
Western Digital Green 500gb hdd

Now, tbh, I'm just plain puzzled at this point, it never BSOD before, I did lose power the other day, but I ran all the hdd, ram, cpu, vga integrity tests i have and they all ran through fine. I have the crash dump file I'll attach here.

It happens anywhere from 10-45 seconds after entering my password. I feel like ...

G560 Laptop hang in BIOS

Go to Solution. Solved! I'm stuck!!! What do I do ? If you installed BSD alongside Windows (dual boot)you may have installed boot loader wrong.More info needed, BSD version/distribution, how youinstalled, etc.

Maybe just install again?

I installed BSD (needed for work) on a Lenovo G560 laptop and on reboot the laptophangs at BIOS screen. Going to SETUP or Bootable options doesn't work.

G580 many lag and shot hang and some time continuos hang

I just bougth my laptop 3 month ago. When lag or short hang  happens to me, the mouse cursor becomes completely uncontrolable and circulate around its self. Scan the HDD for defects using the Lenovo HDD Diagnostics. and it did not make a difference.

I have a G580 i5 2.40Ghz.

thinking update driver would help, I also updated Intel HD and nVidia driver.... that I launch every day. Nothing out of the ordinary.I formatted this machine, thinking it could something wrong with the O/S ... It could be as simple as opening a new webpage ...

or launching a normal program. Since you've already reformatted the PC, try to:
1. I have owned various Lenovo machines since and I've NEVER had this problem before with any other machine! ...................I see whole of topic that are same as my problem I do what they do but my problem doesn't solve. As an alternative, you can use HD Tune to check for bad sectors on the HDD.
Let me know your findings.

win7. 32 bit. Perform a clean boot - this makes sure there's no application on the background that's causing the lag spikes.
1. The important part is, nothing major may be running, nor did I do anything major on the machine.

specialy my problem is very simillar with topic "T410: lag spikes/short hangs/unresponsive system" that solve his problem .

Hang Before Post

Why does it occassionally hang like this? Recently, this did not work. Any suggestions/information would be appreciated.

Usually, I can get around it by pressing the power button. If you have no warranty, I would run a diagnostic on the hard drive and the memory. I would reseat both.

If you have a warranty, call support.

No matter what I tried I could not get it to shut off the screen or to start the post sequency.

ThinkPad x201 8GB RAM 500GB HD Windows 7 Ultimate x64 Occassional, when I poser on the machine I will get the initial gray screen and the system just hangs. Probably, something is failing in the POST. The system just sat there with a gray screen -- brighter at the bottom and getting darker toward the top.

Finally, I pulled the battery and then put it back and was able to start the machine. Is there any type of reset button somewhere (like a desktop has) that would allow me to reset the machine without pulling the battery?

Serious Hang on POST

Looks like a loose connection somewhere.

My fathers PC is a P4 at about 1.7 GHz. From a cold boot, it starts to post, but it hangs for upwards of 3.5 minutes at the first line (before memory)

That line looks something like "<CPU 0F12 PATCH ID 0203>

It's not an exact copy of what it says as I'm doing this from memory, but with that as a rough guide, does anybody have any idea on what's wrong and how to fix it?

Check all the cards, memory and cables to see if everything is seated/connected properly.

That line you see is probably the BIOS-version.

pre post hang

Like a fool I said I'd try and help out with a friend's problem PC. Have slaved the hard drive on my machine and checked for viruses (clear).So I thought I'll format and reinstall but still getting the same problem.Has anyone had a similar problem? Had it for a couple of years and then it started to hang on start up.Push the power button on and then wait for anything up to 10 minutes before the POST screen comes up. Try making the drive a master on your machine, d disconnect you current drive, and try booting.

It's running XP pro on a ECS k7s5a mobo with a xp1700 chip and 196 of RAM. If you still get the same problem it must be the drive
I'm tending to think its the motherboard but am hesitating buying a new one in case I get the same response.

Bios Hang & Login Screen hang

I'm running Win 7, 64-bit. It may be that 1 of your RAM sticks has gone bad.

I have two problems..
1st problem is that my computer hangs at bios. In the past, it's been always doing this.

In the first instance, re-seat your RAM sticks on the motherboard to see if that helps.
2nd problem could be caused by the first. It'll beep and hang, beep and hang, 3 times until it eventually starts to load. This began happening after I installed my Gigabyte 760 graphics card.
2nd problem, and the bigger problem, is after I type in my password and hit enter, it'll stick at saying "welcome" and show the loading circle but it'll just hang.

Boot hang up at POST

Boot stops at manufacturer's and Pentium 4 logo after making one beep and message "Input 2: HP15. No drives recognized, so nothing with recovery disks. Can always freeze and retry my HD, I guess. I don't know what else to look
at except CPU/fan and the MB.

No keyboard shortcut to Bios. I've attempted:

1) replace power supply,
2) reseat memory chip after rest,
3) reseated RAM sticks and MB plug,
4) removed exterior plugs, was able to transfer some files from the HD to another computer. Any suggestions for me at this point? The only information I can find about this code makes me think its being generated by your monitor.

Sony Vaio desktop, 2005, has boot hang-up, and after slowly going
through the obvious, my question is if there is something I'm missing? Did you see a message saying " Out of scan range"? Do you have another monitor you can try?

New build - hang after POST

I am building a new system:

Gigabyte GA-7000-L
AMD Athlon 2700+
512 M Crucial DDR (2 x 256)
Antec Case

I have assembled the above components, along with a (very) old VGA card and a floppy (no HDD), to test the configuration. FYI, I have no other hardware at my disposal to test individual components. I am unable to enter BIOS.

As far as I can tell, the board is set correctly. When I boot, POST seems to be OK (only 1 beep), and I get a correct readout on the screen (Award BIOS / AMD 2700+ / 526..... OK), but then the computer hangs. The clock multiplier is set for Auto (necessary for this high of a CPU), I have nothing extra (except for fans) added in yet.

Can anyone help me with this issue? I have reset the BIOS (both via removing the battery and shorting the "CLR_CMOS" jumber), no change.

Weird POST hang.

Also ever since this has occurred I've had no onboard sound/input for microphone (when its plugged in it says otherwise). And it is well known that  batteries like this when nearly discharged can cause some weird faults.
With regard to your microphone problem, if you have a look at your audio in Device Manager, are there any exclamation marks or other warning symbols against it ?  Once you have sorted out your boot problem, uninstalling and re-installing your sound drivers might be worth doing.

Now I'm having an odd error with my POST. I had a random day where this no longer occurred and it booted fine, but nothing since then.

It wont continue to boot unless I press a key on the keyboard, No key specifically however. Whenever I turn my computer on it will pop to the bios and hang. Reseated all devices Ram/Video/PCIE/CPU.

First of all, welcome to BC !


Computer hang in POST

I found the LED display on the motherboard, and the configuration indicates it is hangingup at the" initializing floppy drive controller", what does this mean, and what should I do about it?
I've had an occasional problem starting my computer, the problem is when it hangsup in the POST.

Long hang before POST

I am running Windows XP. Try entering BIOS setup, then select "Load Setup Defaults" then Save and Exit

I assumed I bricked the unit as most comments on a failed bios update seem to emphasise that the error is irreversible. However, after 15 minutes of blank screen the system begins to boot, shows the post and loads windows fine.

Everything seemed to be going fine but after reseting the laptop refused to show anything on screen.

I have a Thinkpad W500 and recently updated the bios to the most recent version. Every time I reset or turn off the unit, the 15 minute hang continues, Is there anyway to prevent this from happening or fix the problem? So far I have:- ran memtest86 to check the ram- ran chkdsk to check the hdd- downgraded to a previous bios version- updated graphics drivers, SP3, etc. None of this has had an effect upon the boot. I am unsure what is responsible as I recieve no warnings, errors, beeps or anything that would give me an idea what's wrong. Any help would be hugely appreciated.

I now regret doing so.

Second hdd makes POST hang

It installed fine, I formated it to ext3 under ubuntu, and then installed ubuntu 7.04 to it. I used this system for a month or so, then tried to install FreeBSD to the new old hard drive. Removing the original hard drive booted Ubuntu, and removing my new hard drive booted FreeBSD.

Recently, I bought a second western digital 160GB drive. However, I'm guessing something must have gone wrong, as now my machine is unbootable. It will cylce through all the BIOS POST stuff, but then hangs with a non-flashing cursor at the top corner of the screen; no grub or anything. Any advice would be really appreciated, I'm completely out of ideas!

Try to completly clear the hdd with delpart and than try out again your FreeBSD installation.

I'm currently using an IBM x206 server, with two SATA hard drives. I have tried completely wiping the old hard drive from a grml livecd, using the command;

dd if=/dev/zero of=/dev/sda

However, this doesn't clear the error. Greetz

Originally, I had a dual boot system with windows xp and ubuntu 7.04 on a single drive.

Computer freezes at POST/DMI hang



So far I've removed/disconnected both harddrives and the graphics card. I also tried clearing CMOS both by removing the battery and disconnecting power and by using a jumper.

It'd be really cool if I got this to work. When I can, I can get through a few screens or keystrokes before it freezes and I have to do a hard shutdown. Occasionally this now prompts a "CMOS checksum error // POST error occurs!" box, which like BIOS freezes after a few keystrokes.

Motherboard: Gigabyte GA-G41M-ES2L
CPU: Intel Core 2 Quad 2.5GHx (Q8300)
HDD: 1x 500GB SATA (on SATA_0)l 1x 1TB SATA (on SATA_1)
PSU: 480W generic ATX PSU
Graphics card: nVidia GeForce 8600GT
WiFi card: TrendNet PCI card
DVD-RW drive not connected during testing
Today I installed a new motherboard and CPU, without changing any other hardware.

Also like BIOS, I lose power to the keyboard. When I first powered on I got the 'Verifying DMI pool' hang error. Most of the time there is no power to the keyboard (I've tried both PS/2 and USB), so I can't enter BIOS. After that, when I powered on it alternated between freezing at POST, hanging at DMI and freezing in BIOS.

g450 hang after post (bios)

Need a new hard drive, I think.

First of all sorry about my inglish im from argentina.My notebook wont start, try to start from a live cd but it dosnt work if a have the hdd install, but if i unistall the hdd the live cd works.. i try change the ram slots, it dosnt worktry format the hdd from another computer, dosnt worktry disconnect the battery, dosnt work please help me!

POST Hang and Game Freezes

And to gain experience with BIOS flash procedures and maybe look into overclocking... I figured I better test it to see if I can reproduce the POST hang issue so I re-inserted the USB drive and rebooted and sure enough, it hung at post for 1 minute again, removed the drive and back to normal. Now I am sure something else will come up so I don't know if I can safely say the issue is resolved but this is progress. I left my OCZ usb drive in the top panel so why not remove it and see if it boots up normally -- Annnd wham it's fine.

I assume it might be a good idea as my registry is probably pretty messed up now cuz of CCleaner. Could be RAM settings or timings (Set to 1.9V 5-5-5-12-2T as per Corsair's Spec) or the fact that I'm using 4 modules. I also forgot to mention in my first post that I had upgraded my mobo BIOS from 0702 to 1804 (which is a beta BIOS and that worries me). I have heard a lot of people have problems with the Asus M2N SLI Deluxe board and or the Nvidia 570 Chipset on it.

I later found out that I was reading low on the +12V2 on my Antec PSU checker and assumed that my Thermaltake 700W Toughpower PSU went bad, so I RMA?ed it while simultaneously ordering a Corsair 750W to replace it (as I no longer trust Thermaltake). The MAIN problem I am having is the system hanging at POST for 1 minute (usual time is like 1 second) AND intermittent freezes in games that are graphically demanding. Now the funny thing is it probably wont do it tomorrow when I...
