Two ThinkPad X1 Yoga Gen2 TabletPCs will successfully boot into Windows 10 just fine from a hard poweroff.  But once in windows, if i choose Restart, it will hang at the "LENOVO" BIOS  level boot up logo with "To interrupt normal startup, press Enter".   Stuck at Lenovo BOOT BIOS initialization screen, right before handoff to the Operating System. "To interrupt normal startup, press Enter" At this point, pressing ENTER does not work.CTRL-ALT+DEL causes the screen to change shade for a moment, but effectively does nothing.Changing the UEFI settings to diagnostics results in black screen.Holding the power switch to force a poweroff, waiting a few moments, and then powering on results in a successful windows startup.  DevMGMT.msc does NOT see bluetooth and there is "Unknown USB Device (Device Descriptor Request Failed)" entry under "Universal Serial Bus controllers".  I have run all automatic updates via "Lenovo Vantage" and the manual TPM update.   I can boot into the firmware setup and have had it revert to factory defaults and reverted to factory defaults for all security settings.   I even tried the Win10 repair startup problems, but it says it cannot fix this.

It looks to me like you have a faulty hardware issue or a serious driver issue. Try the Lenovo recovery to put the device back to the factory windows install. If that fails, I would think you have a hardware issue.

Hi you guys!I would like to excuse my bad English in advance. This happened like three days ago. Regular reboot. No forced updates or any installation, just an ordinary reboot.But then, all of a sudden, I couldn't work my ass out of the boot screen. It doesn't go in to loop either, just standing there, acting like a d*ck. I've tried ALL F-buttons but none has worked at all. But if I FN-lock them, I can change the brightness and that kind of stuff - SO, it's responding, but nothing more nothing less.And because I can't choose different boot, neither go into BIOS, I feel kinda f-ed (did my motherboard actually brick it self?!)Tried so far: BIOS battery, int+ext batterypack, w/ and w/o AC adapter, disconnected the harddrive, disconnected the RAM. And you know what? The same screen. ALL of the times.Any suggestions? Try to recover bad sectors (if any) in another computer? I would love to have USB>S-ATA right now, but I'm going to use it ONCE, so that's out of question.Kthxbye, love <888

Hello everyone, Similar topics have been raised in this forum but I could not find an explanation and fix to my issue, so here it goes : I just received my brand new P51 and noticed that when I select Windows 10 reboot, the laptop hangs when the Lenovo logo displays (displaying the "press enter..." message), powering off and rebooting being the only option. Shutting down the laptop and rebooting from power off works fine though. I tried several scenarios, including updating the BIOS to the latest version (1.17), pressing PF12 to change the boot order, etc and I finally figured out a way to make the reboot work : assigning the NVMe SSD containcng the W10 partition as the first line in the boot order, moving Windows Boot Manager that was intially #1 to #2 in the list. I have no clue why that makes a difference ? Also, I may be wrong but it seems like the boot takes a little longer now.  Anyway, I can live with that now, but I would really like to understand what is happening. In particular as I plan to add a second SSD for Linux and want to eventually be able to select Linux vs W10 at boot time. Thanks in advance for your feedback (thats my first post in this forum). cheers, Philippe

I've done a lot of research on this and am still stumped.   My trusty T500 started to do random shutdowns a few weeks back.  Sometimes it would restart with no issue, sometimes I would need to briefly remove the CMOS battery to get it to restart.  Now it will only "try" to start, showing the power on, the "Z" light and the bluetooth  indicator light but no Thinkpad splash screen or POST.   I can hear the disk start to spin then.... nothing.   I have ordered a new CMOS battery and have tried the remedies such as removing RAM, CMOS, etc with no change.   The computer was working quite will before this situation.  I have seen suggestions that I have a bad poly-fuse and that would make some sense if it was resetting, in partial failure or failed. Has anyone experienced this and what did you do to resolve? Thanks,Dave

A:ThinkPad hangs on boot - stuck at Thinkpad screen

You might have damaged the power circuitry on the motherboard.  If that is the case, the only solution is to replace the board.  There is an array of power transistors that handles the switching back and forth between AC and battery.

Problem is similar to others that have been posted earlier.

On boot sequence, PC hangs on Windows boot screen - with the good old progress bar churning along for eternity. It just stays there. It is possible to boot into safe mode, safe mode with networking, etc. but never boots up normally. 'Last Known Good..." does not help at all.

I have tried 'repairing' XP using the recovery console (deleting the boot.ini file, then BOOTCFG /REBUILD and then FIXBOOT) to no avail. Do not know where in the boot process it is getting hung up and not totally sure how to determine that.

Using Windows XP Media Center Edition with SP2. Plenty of RAM and disk space.

Had this problem once in the past and it seemed to self correct after about 50 reboots. No such luck this time.

Does this sound like a re-install of XP is required or are there any other options that might work?
Cheers, GR

More problems with my nephew's computer again!

He tried to access Microsoft Word on his new Dell Dimension and when he couldnt find it, used the disk to install from...got impatient (he's 13 and a complete novice) and started clicking around. When he shut the 'puter off and turned it back on again, the Dell logo comes up, then the XP logo on the blue screen comes up, but then it hangs and wont boot into Windows. I tried having my sister hit F12 to go into the boot sequence and told her to press 1 but it still didnt work. I then tried having her hit F8 and then F2 after (shutting down both times) and she still cant boot up.

Any chance he uninstalled XP by mistake? I'm not sure what else to tell her to try (over the phone at that!)

Appreciate any advice or ideas of what to try. Thanks

Hello everybody,
I've got this problem on my pc (Thinkpad IBM with WIN XP PRO SP2)

Boot hangs at Winxp logo (the lines under the logo go on 6 or 7 times); PC stops, CTRL-ALT-CANC doesn't work and the only way is to switch off and on the pc.

Switching it on again pc stops again; after a certain number of switching off/on (can't say how many, maybe 5 or 6) it finally boots and everything works fine (for an entire working day).

I have tried to boot in safe mode, minimal and network: it works everytime without problems.

I have tried to boot with the flag /basevideo (driver VGA 16 colours) but it hangs the same. So I don't think it is a video driver problem.

Booting in safe mode /pcilock doesn't change the situation.

I have changed hard disk and completely reinstalled the o.s. and the SP2.

Here is a part of the bootlog file ntbtlog.txt:

My son has killed his computer and I am not sure if it can be saved from home or not.

I would say he somehow got a virus and its done this.

When we power on his computer we get the windows logo with the options to go to the Setup and Boot menus.

We can not get to Safe Mode.

We can not get anything to happen when we try to boot from OS or CD. I can get into DOS but nothing will actually run from DOS so that hasnt helped me much.

I am at the end of my limited knowledge on what to do. I am assuming the master record boot whatever is dead or gone. But everything I have read about that tells me to fix it with the windows disk. But since I cant get it to work at all i am dead in the water

Any ideas at all?

Seems that after flashing a custom bios to my T420s, I've lost my "Thinkpad" boot screen logo.  On startup all I get is the bottom line -  "To interrupt normal startup, press the blue ThinkVantage button", before it boots normally.  No "Thinkpad" or "Lenovo" logos. I've tried re-flashing with several stock BIOS's but each time I only get the bottom line.  I've also tried following the "BIOS_LOGO" instructions (C:\Drivers\Flash\8cujxxus) for installing a custom startup image, but nothing I've tried works.  Both Winflash and Winuptp have options for changing the startup image but neither seems to work. Any suggestions on what I might be doing wrong ?.  Thanks.

Brand new Dell XPS 13 Ultrabook with Windows 8. 256 SSD, 8 gigs of memory, i5-3317, non touch screen. Working fine for 2 months and now will not boot after Dell logo. Have been on tech support three times still not solved. They sent a USB recovery drive and does not boot. They sent an optical drive and the windows recovery disc; still not working! Not a novice at this but fully stumped. Cannot get to a C prompt, cannot get into Safe mode. Am able to get into BIOS but is limited in what can be done there. Diagnostics says everything is fine. Am ready to go back to Windows 7 until they work the bugs out. Please help and thanks in advance.

A:Windows 8 hangs after Dell logo and will not boot!

Based on the symptons you report, I doubt that it will work on Win 7. Its not the OS, its some other problem.

If it "will not boot after Dell logo" that says it won't even go to the BIOS (F2 setup). Actually it will not boot after the BIOS and not boot from any device. That says either a motherboard hardware problem or a BIOS problem. Have you tried resetting the BIOS?

Have you been on the Dell Community users forum (users helping users like this forum)? People there with more specific Dell knowledge. There is a Laptop hardware section. Dell also has an unresolved issues on-line link that many times can escalate open problems.

Hi,My SL510 will not boot past the ThinkPad / Intel logo. The keyboard is completely unresponsive so cannot press any function key to interrupt normal startup to try access bios or access repair options. The USB mouse briefly lights up as power is registered at port but then goes out.I was not last person to use it and unfortunately rest of the family are IT illiterate so they've no idea if can remember if it had issues when shutting down etc. So far I have:Removed external power & tried on mains only.Removed mains and tried only on battery power.Removed hard disk, booted to see any complaintsRemoved RAM, swapped it around and used only 1 RAM board in both slots. It beeped unhappily when RAM not present but made no difference. Nothing has made a difference. At moment fan is running whilst sat at boot logo but will often just stop dead at same time the screen appears. Certainly does if cover is off.Help!Thanks

This is the strangest thing. After installing several Windows Updates, and updates specific for my laptop when I boot the process hangs just after the logo screen. I can see the desktop background, but no icons. I have a mouse cursor but nothing else. It stays this way indefinetly, until I press the <esc> button. Once I do that it immediatly finishes booting. I really don't care, I'm just confused, I've never expereinced anything like this. Anyone else ever had this particular issue?

A:System hangs after boot logo screen

Hi, cbieger, I haven't experienced this but let's try some standard troubleshooting steps.

1. Remove any USB devices that are connected during the startup (flash drives, external drives, keyboard, mouse, cameras, printers, scanners, etc), also remove any discs that might be inside your optical drives, also remove any external ZIP drives, and boot to see if this issue is reproduced or not.

2. Launch your Device Manager. To do so, press Windows key + R, type devmgmt.msc, and then click OK. Go to the View menu, select Show hidden devices and check for yellow exclamation or question marks. Report any discrepancies.

3. Reboot and press F8 in order to select the type of startup. Select Safe Mode and see if this issue is reproduced or not.

4. Perform a clean start (see how to do this here) and boot again to see if this issue is reproduced or not. After that, return your PC to its previous state in order to move on with the ensuing steps and reboot.

5. This time you'll have booted normally. As soon as you get in Windows, launch the Event Viewer (to do so, press Windows key + R, type eventvwr.msc, and then click OK) and see if there are any Error Events associated with this behavior.

6. Force a verbose startup. To do so, press Windows key + R, type gpedit.msc, and then click OK. Expand Computer Configuration, expand Administrative Templates, and then click System. In the right pane, double-click Verbose vs normal status messages. Click Enabled, and then click OK. Cl... Read more

Typically the problem is somewhat intermittent and happens on the first startup for the day. The hang is at the XP logo screen were the blue progress bar continually cycles. To solve the problem I press the reset and this takes me to selected start were I choose start in Safe Mode and then restart to normal. I then can restart any number of times during the day with no hanging.

I have removed the computer from its original location and thus from any and all external peripheral components, i.e. printers, scanners, copiers, sound system, game controllers, USB flash drives.

I relocated the computer and connected a new key board, mouse, monitor, sound system, and a modem cable for internet and the problem still occurs in the new location with all new or different external components.

I have read through several like posting on these forms, however, I have not found anything that is acting similar to what I am experiencing.

There are a couple options I am going to try that I found on the postings, the one in particular is the HD SATA cables, after that I have no options and will be looking for suggestions.

Any & all help will be greatly appreciated.

New Dell XPS8700. Upgraded from Win 8.1 to Windows 10 and worked fine for about a month.

On start-up, it now hangs on the Dell logo or when trying boot options to start from USB or recovery DVD go to blank black screen. Dell phone support sucked but they sent me a recovery USB drive (to factory set Win 8.1), however start-up would still hang at the Dell logo. Tried all different boot combinations from CD/DVD, USB, OS/Boot partition but cannot proceed beyond Dell logo or black/blank screen. I do not have a original Windows 10 OS disc, however did a download from
HTML Code:
to USB and PC does not boot up from that media either.

Used an original Windows 7 Ultimate installation CD to start and get to command prompt to recover files from C: drive and can browse through all folders and files. Copied user data to USB drive. So HDD appears OK.

Any ideas? Please help!

A:Win 10 hangs at Dell Logo despite various boot options on XPS8700

If it hangs at startup and the Dell logo, its doing a Power On Self Test. Do you get any beeps? (and if you do what is the pattern) as that will help in troubleshooting. F12 at power on will access a menu (if it will get to that) and one option should be hardware diagnostics.

You could also go to the Dell community forum where those familiar with Dell's can help.

Hello. I have 3 year old Lenovo Y50-70 laptop. Couple days ago i decided to finally upgrade to SSD. The old HDD was 1TB WD 10SPCX and i replaced it with 480GB Kingston UV500 SSD. When I swapped the drives and tried to boot, I was stuck on completely black screen with only Lenovo logo. This ocured when I tried to enter Novo menu using Lenovo Novo button as well. I tried to put back the old HDD and it was working normally. When i pulled out both disks and tried to boot only from bootable USB this problem did not occur. Then i tried to plug the SSD to some HP desktop computer and I was able to install windows there and boot on the desktop normally. So I put the SSD back into my laptop and again i was stuck on the logo. However, because Windows was now installed, I was able to boot after being stuck on the Lenovo logo for some time. Then I tried to change the SATA controller mode. I tried both Compatible (IDE) and AHCI modes and installed fresh windows using both settings but still I was stuck on the cursed Lenovo logo. The lag lasted ~1 minute when usind the IDE and 6-7 minutes using AHCI setting.  My bios version is the same as the version available for donwload on my laptop drivers page (V3.03). Using bios options to restore to defaults or OS optimized defaults did not make any difference. All the drivers are installed and up to date, though I think this is irrelevant as the problem first occured before any OS was present.  Could it be t... Read more

I have a Thinkpad T21 with Windows XP SP2. The issue is that when I startup the laptop, during the Windows XP loading screen (the wone right before the login screen), the system becomes unresponsive. The wireless PCI card goes on and the Caps Lock and Num Lock lights blink, then everything hangs.

I am able to get to Safe Mode, and have disabled all startup items. Also disabled as many services as possible. We did a reformat and the same issue has occurred after reinstalling some software. I did suspect that this may be a driver issue, but I checked the Device Manager and did not find any issues with any of the devices. Note I also removed the PCI card from the system.

I suspect that this may be a driver or service issue. I am not exactly sure any there are too many places to look.

Anyone have any recommendations? Thank you.

I bought an ASUS N76 laptop pre-loaded with Windows 8 so these are the new generation n76 series. The old ones come with Windows 7. Anyway...

I attempted to boot a Windows 7 ULT 64 install DVD but the install hangs on the Windows logo/flag. So...

- Windows is loading files is shown and hidden
- The animated Windows logo appears and then it just hangs....go figure

I have no idea what is going wrong. I went into the UEFI setup and the only option for my BR is EUFI boot.

I also added a "boot option" asking the EFI to boot "efi\microsoft\boot\boot.efi" or "\efi\microsoft\boot\boot.efi" but when selected (from Boot Override), the screen goes blank for a few seconds, the BR starts spinning and I am thrown back at the EFI so it looks like it cannot find the file. For path, I selected the BR device and at the end has a "\".

I have secure boot disabled. (yep, I have an option for that). So now I am left empty handed and I am stuck with Windows 8. I even put in a brand new SSD hoping I would install W7 on it but I can't even start the setup!! Argh....

I am very experienced with MBR and BIOS but I am a complete newbie to UEFI. I don't know what is going wrong and why the setup hangs....Ther... Read more

A:Asus N76 UEFI - W7 64 Install Hangs on Logo (DVD UEFI Boot)

Win8 PC's have Secure BIOS which must be disabled to install any other oS, then you can install in UEFI mode following these steps: Downgrade Windows 8 to Windows 7

If you want to bypass UEFI and install normally to an MBR drive the procedure is related here: MS new "Secure Boot" locked BIOS arrives

Has anybody else experienced this?  I would STRONGLY recommend that you DO NOT upgrade to 1.43 as it will break keep you from being able to boot up consistently.  It does not matter if you have a current install or try to reinstall, Windows will not boot up most of the time. I found https://support.lenovo.com/us/en/solutions/SF16-T0079 and it does not state T420, probably because it is no longer under warranty, but this issue was definitely introduced with 1.43 and Lenovo released this buggy BIOS code to many models not listed. Below is part of the release notes. CHANGES IN THIS RELEASE  Version 1.43[Important updates]- Security fix addresses LEN-8324 System Management Mode (SMM) BIOS Vulnerability.  (Note)  If the UEFI BIOS has been updated to version 1.43 or higher, it is no longer  able to roll back to the version before 1.43 for security improvement.[New functions or enhancements]  Nothing.[Problem fixes]- Fixed an issue where the brightness control might not work on Windows XP. Lenovo, please update this BIOS for ALL AFFECTED MODELS ASAP so that those of us who have made the mistake of upgrading to it can continue to use our computers!

Hello, I have had my Lenovo ThinkPad T460p a bit over a year now, and it was always fine. Today I try to open it (from night-long sleep) and it almost instantly turns off. I try to power it on, but nothing: no LED, no beep, nothing. After some online search through my mobile phone, I try this: I unplug the laptop from the main current plug in the wall, I remove the battery at the bottom of the laptop, and I then push the power button (ti flush the capacitor?). After that, when I put back the battery and the plug, and try to power it on, the whole keyboard LEDs get active (including the power LED) but then the whole laptop dies again without proceeding further in the boot. any idea how to fix this? There seems to be no emergency hole reboot unfortunately, and I have very important data on this laptop for my job.
