Stuck at windows starting after bios update boot

Model: Satelitte P755-S5120
Part NO: PSAY1U-OVD026
OS: Windows 7 Home Premium 64 bit
I get stuck at starting windows everytime I restart my computer. This happened right after I installed a bios update and rebooted my computer to finish it. I could never get back in.
I tried running diagnostics but it didn't seem to find any errors. I tried restarting it in safe mode and all other modes but I keep getting stuck at starting windows.
Funny thing is when I restart my computer on safe modes, I could see the files loading and on all of them it always stopped on \windows\system32\drivers\CLASSPNP.SYS
Maybe that file is corrupted, I have no idea.
Also tried repairing, and after it loads window files it goes into a black screen and it stays there, nothing happens. I let it run for an hour or so.
So any ideas? I'm not a computer guy so I don't know what else to do. Please help.

If you didn't burn a repair disc, download one from here. Scroll down to Windows 7 System Repair Disc 64-bit.
Create a Windows 7 System Repair Disc
Use it to boot to the Windows Recovery Environment.
Try the Startup Repair from there. Sometimes it takes several times.
Also, run this disk check at a command prompt. It may take a long time.
chkdsk c: /r
Then try Startup Repair again.

B75A-G41 stuck in reboot cycle after bios update

Hi.
Updated to bios version 17.3 to hopefully utilize my 22nm i5 with 2400mhz RAM. Everything worked ok using version 17.1, but with max 1600Mhz Ram speed.
The update was done using Live update, because the updater available on the MSI site does not run on my system (!). (Win-7 64bit).
After flashing and reboot and clearing the CMOS this is what happens:
I get notified that the bios settings were reset. On the top there is a list of system resources. Everythign looks ok, the cpu, ram, and SATA devices are all there.
The MSI graphic is displayed shortly (maybe this happens first, not sure atm).
After I press F1 to enter setup with default values, it says Setup is loading in the lower left, but nothing happens for a few seconds.
Trying F2 to continue to boot also results in the same.
A few codes are posted in the lower right, these are C9, B4 and sometimes A2
The machine reboots and starts again with displaying codes, reboots etc.
Repeating the CMOS clearing has no effect, other than displaying the initial page with bios reset options.
I can not get into the bios at all.
I would appreciate any assistance.
Cheers,
Andreas

Try a full cmos clear. >>Clear CMOS Guide<<
In the future, don't flash the bios via any windows program or live update.
Download the version you wish to use, then use the forum flash tool.

X301 won't start after BIOS update

Hi all:
Well I've had my new x301 for about 2 months and it's given me nothing but troubles....Recently I found out my laptop won't come back on from hibernation (when you close the screen and open it up). So I downloaded and installed the lastest updates from Lenovo (including the recent BIOS update), restart computer, only to find out it doesn't start up anymore...black screen, thinkadvantage blue botton doesn't light up, no harddrive activity, only light on is battery and power...
I'm thinking maybe something went wrong with the BIOS update. Is there anything I can do to fix it (besides shipping this thing to a repair center which is a big hassle, or paying $200 for an on-site tech that might or might not solve the problem).
Any help is appreciated.

Hello all
I just updated my X301 (2776LEG) with the 3.12-1.05 bios. Now my laptop won't start up when running on battery, it powers on for a short while and powers off again. This cycling keeps on going (after 30min I switched it off!) but as soon as i connect the power adapter it boots fine. Seems like this bios update f****ed up the battery power part of the computer....
I tried the bios battery trick but it only worked on the first boot and after that the same problem is present.
I have added 2gigs extra memory and a ultrabay battery and it has been working 100% for about a year now. This error started right after the bios update...
Thought that a reflash of the bios would solve the problem but i cannot reflash the bios with the same bios version...
Any ideas ?
Kind regards
Tommy

Portege Z930-118 wont start after BIOS update

my PORTG Z930-118 failover and wont start after i upgrading in middle of upgrade i remove power and press shutdown bottom after that i see the power and wireless but screen still black ?
Any help please

Hmmmm.... BIOS upgrade interruption has screwed up BIOS and thats the reason why your notebook doesn't start properly. BIOS is damaged now.
In such case you need professional help by authorized Toshiba service provider.
On this forum you can find many threads about similar problems. Some people have tried to fix this alone and if you are interested to read how one other forum user has fixed it check please this thread.
Ayway, you can contact nearest Toshiba service, explain the situation and ask for help.

Satellite A100 - Windows and BIOS doesn't start after BIOS update

Hello, I have updatet BIOS of my notebook sattelite A100.
After updating I cannot start my notebook and BIOS doesn't start.

Hey guys... I tried to update my girlfriend's BIOS on a A100 just now (the windows installer) and the procedure stoped in the middle because windows crashed while doing. Now the laptop won't start at all (obviously). I have a black screen when turning it on. No boot sounds or anything. I've already removed the AC power source and battery in case that works. I guess removing the BIOS battery won't help either since the flashing was wrong... In case that doesn't work, is there any chance i could find a BIOS from ebay or somewhere else?
Thx in advance, Jimmy..
PS. My gf is going to shoot my brains out :P

Notebook does not start after BIOS Update crash

Hi all,
I just want to ask whether is a chance to reactivate my Satellite A300 after a BISO update crash without send it to the Toshiba service.
I downloaded the new BISO and started it from the Windows menu. After a few seconds my PC crashed and everything was frozen.
I switched off the PC.
Now when I press the power button to start the Notebook the monitor is black and I can hear a sound brrr, brrr, brrr from the CD-Rom drive.
Do you think it is possible to boot from a CD or something like that. Is it possible to reactivate my notebook?
Your help would be really appreciated!
Thanks a lot
Best regards,
Chotte

Sorry but if the BIOS chip is damaged there is no much you can do about it. You must contact authorized Toshiba service provider.

hi! you probably upgraded to 5FCN95WW BIOS, didn't you? you need to switch boot mode in BIOS. I can't remember which option is enabled by default, but there are only two of them - UEFI and Legacy. you have to change to the one that isn't set by default by the way, you should know 5FCN95WW is buggy, and downgrading to 5FCN35WW would be your best bet. once you sort the boot problem out, check this guide to downgrade: https://forums.lenovo.com/t5/Lenovo-P-Y-and-Z-series/Guide-BIOS-Downgrade-from-5FCN95WW-to-5FCN35WW/td-p/1781189/highlight/false

This question was solved.

I extracted BIOS softpaq sp55553. It is BIOS version F.20. It had the .SIG file inside when extracted using WinZip. You do not need to make a bootable usb flashdrive. Just put the files at the root of a FAT32 formatted usb thumbdrive, plug it into a usb 2.0 port. Hold the Win + B keys down and press the power button. Continue holding the keys down until the notebook reacts. It usually takes a bit longer than 15 seconds to respond and begin the BIOS recovery.

Toshiba P755-S5270 Won't start after BIOS update failure

I was informed by Toshiba Service Station that I needed to update my BIOS. During the update, my laptop froze. After powering down it would not start again (Black Screen) the power comes on but nothing else.
Any ideas?

I understand if I would have just decided that I would change the BIOS for no good reason, I have what's coming to me, BUT when Toshiba's program "Service Station" that came loaded on my laptop, says that I need to update and I use Toshiba's program "Service Station" to do just that... and it fails... one might think that the program is to blame.
If this Update was suggested by anything other than an approved program that came loaded on the laptop, I wouldn't have done it.
What really irks me is that I've owned this laptop for one year to the day and my warranty just expired!
Oh Well... Lesson Learned.

Equium A60 does not start after BIOS update

I have an Equium A60. After being caught with some very nasty malware and a trojan I made the disiccion to reformat the machine and reinstall the o.s..
All went well until I updated the bios. Machine crashed and now I cannot get it to reboot. Press the power button and the machine will start for 3-4 seconds and then shuts down.
I know this is due to the bios and want to know if there is any way that i can reset this back to it original settings?
thanks in advance for your help

Hi Rob.
The model of my laptop is EA60-152 / PSA67E.
Yes i did upgrade from the Toshiba website.
I should have never done this it was working after the reinstall of the o.s and so i should not have tried anything else(never fix something that aint broke).
The only place i have found for a new motherboard is Toshiba. But the price is nasty. Talk about what a fool am i.
Never mind though i keep on thinking that there may be an answer or a scrap one that i can rob a bios chip from. Other than that a very nice paperweight me thinks..!!!!
If i get an answer than i will post it here..

MSI Z87-G45 Gaming- computer wont start after bios update

X201 won't start after bios update

I just updated the bios from the download I got through lenovo system update, it completed fine then shutdown.
Now it will not power up not even to post screen, I have removed all parts and tried removing backup battery but still nothing.
If anybody knows of a solution help would be appreciated.
Lenovo x201 i5
Type 3680

if removing the battery and press the on/off buttons ten times doesn't work then you have a bricked BIOS.
1. Either you get a new motherboard
2. Find a company that can reflash the bios on the hardware level.
