hi sathish291
Welcome to the Forums.
Can you try the following:
1. Power down the machine, remove the AC adapter and battery.
2. Hold the power button for 30secs and reconnect the AC adapter only then turn the computer ON.
If the machine still doesn't power up normally and boot into WIndows then it's likely that something went wrong (could be a bad BIOS flash or an internal component might have gone defective during or after the BIOS update). In this case, you may need to contact lenovo on how to go about getting the unit serviced.

Satellite Pro L300 will not boot after Bios update

Help please.
I have just formated a Satellite Pro L300 laptop.
I used all the updated drivers from Toshiba and all went very well.
I then updated the bios with the latest version.
After doing this the laptop will not boot but just keeps scrolling through the start menu and no matter what option I choose it just keeps doing the same thing.
Any ides welcome

Hi
I used the Microsoft installation disk but just keep getting to the same stage until the blue screen appears. I have tried different installation disks and also changed the hard drives as well. I can do everything in bios, change boot device enable or disable devices but that is it. I have tried a few times to instal windows but it just stops at the same point saying windows is stopping instal to protect the system. I fear the bios update has done some permanent damage as I cant get past the dreaded blue screen.Thanks anyway

HP G62-a22se not booting after bios update

Yesterday, i downloaded an update from HP's site for my bios and since my laptop is not booting. on reboot i see the caps lock flashing twice each 2 secs. is there anything i can do to reflash bios or undo the update?? any help would be appreciated.

Disconnect all peripherals from the laptop. (external drives, mice or other devices)
Remove AC power, remove the main battery, locate and then remove the RTC coin cell battery for 15 minutes. RTC battery is located in the memory module bay on this model, L shaped cover with 2 screws, you will need to remove the main battery before removing this cover.
Put the coin cell back in and connect AC power only, see if it will post the HP screen, if it does Immediately use F10 to enter the bios and set the date and time, save changes on exit.
If it does not start, power it back down, hold all 4 arrow keys down and power it up while holding keys for 2~3 seconds after power up, let up on the keys and wait (2~3 minutes) to see if the bios recovers. If you get the HP post screen, enter the bios and set the date and time before booting into windows.

Laptop won't boot after BIOS Update

My laptop took an automatic BIOS update
Now when I try to turn on my computer it won't turn on:
Screen is black
Power button and f12 button lights flash at 5 second intervals indefintiely
At the same interval a fan or hard drive can be heard spinning for a split second then stopping
I've tried the hard reset (Remove power and battery fo 5+ minutes, plug in power but no battery and turn on) but no affect.
The Windows key + B key with the power button for 1 second had no affect either.
I can't find any info with my exact problem (All other info seems to have blinking light codes while mine is just at a constant interval)
Thanks!

@B1-17 ,
Thank you for posting back. Now based on how you are explaining the response you are getting after doing what you have done so far the next step will be to try and get a response with removing some components and then see what kind or response you get.
Here are the steps you want to follow.
First remove your memory from you notebook. Here is a link for the Maintenance Manual that will show you how to do this.
(When Removing Or Adding Any Part To Your Notebook. Remove Battery and Power Cord.)
1) Remove bother Memory Modules. Put the power cord back in only.
2) Start your notebook and see if a new flash code or beep code happens.
3) If yes place only one memory module back in to your notebook and try rebooting.
4) If you boot up then we have a bad stick of memory.
5) If you still have a flash or beep code. Remove the single memory module and try the other.
6) If this lets you boot up. Replace memory module that is not in the notebook.
7) If you still have the original problem or a new beep code. Power down again.
8) Now remove power cord then the hard drive. Use Maintenance and Service Guide for instructions.
9) Try booting up again and see if this changes the original flash code or beep code.
10) If yes then replace hard drive if no then contact phone support for repair options.
At this point if there is no change in the original flash or beep code you are looking at a repair. For information on how to get your system repaired please contact our phone support.
Please call our technical support at 800-474-6836. If you live outside the US/Canada Region, please click the link below to get the support number for your region. http://www8.hp.com/us/en/contact-hp/ww-phone-assist.html

Lenovo w510 will not boot after BIOS update

Hi,
This morning I used the windows bios update utility to update my Lenovo w510 type 4318. Everything appeared to have been successful until the machine rebooted. It froze on the lenovo splash screen with text saying to press the blue think vantage button for more options.
I waited a good 30 minutes to make sure it wasn't processing anything before trying again. When frozen pressing the power button cause system to beep two times Pause and beep three more times.
Called Lenovo support and was told since out of warranty (2/12) the onlyI option is for paid mail in repair at quoted maximum of $575. Needless to say I was very dissatisfied - and made this clear to support who informed there was no way to escalate and no other options.
Does anyone have any other options or ability to escalate this case and keep a Lenovo customer. really disappointed
Case #9026SN6
Btw, reason i updated bios to fix issue with usable ram showing 3 gb.
Solved!

NEVER use the .EXE method for a BIOS update. Always use the .ISO and the CD/DVD boot method. Never update after the warranty expires.

Computer will not boot after bios update

This afternoon I recieved an urgent BIOS update in much the same format as I have received updates from HP for years. It was accompanied with some other non urgent update.
So I gave the permissions to make the update.
I recieved a notice that the update had been successfully completed and the computer said it was restarting.
The problem is that it never woke up...
After several minutes I manualy restarted the computer.
As the boot began I heard three beeps, and then nothing but a black screen.
I shut down and restarted after several minutes but this time no beeps just black screen.
I figured that somthing must have corrupted the BIOS
I began researching what the three beeps mean. Appearently three different sets of BOIS were used in this model. Different BIOS have different beeps.
Well I sure never thought I would need to write down what BOIS I have...
In my research I have see referances to holding down certain F keys for different BIOS options as I start the computer
If I hold down an F key when I hit the start button the computer emediately shuts off
How can I get to the BIOS to reset or roll back the update? What next?

The box is on the way...
In addition the the methods outlined in the article The Hp tech had me try to start tapping the F 10 key.
Nothing worked...
Hp is sending me a box to return the computer to a repair facility.
Thank you for your timely assistance,
Sparks

Dm4-1165dx not booting after bios update

I recently tried to update the bios on a DM4-1165dx from F.23 to F.27 as I recently formated the disk with windows 7 pro, I downloaded all the requiered drivers and everything was running smoothly until I ran the bios update tool, followed the instructions as said, waited for more than 5, noticed that the update window dissapeared then the fans started working at high speed. This lasted around 13 minutes. (now being almost 20 minutes) the bottom of the laptop was really hot. The mouse wasnt responding, neither did the keyboard (tried to get taskman to cancel the process). Waited 5 more minutes until I decided to pull the power cord then it just turned off.
Haven't been able to turn it on.
Already tried:
1.- removing the battery, waiting, power, windows+b, HP_TOOLS usb
2.- removing cmos battery, removing memory modules installing new ones.
The blinking leds were blinking 2 times acording to this:
Troubleshooting LED Blinking Lights
is a problem with the bios, I need help troubleshooting this issue as the bios is so new I haven't found any troubleshooting available.
PLEASE HELP!

You can boot and recovery to your previously installed BIOS version.

Satellite C660D-104 does not boot after BIOS update

Hello,
I installed the latest bios on my computer Satellite C660D-104 but it has not rebooted.
Where is the place to do a reset?
Under the ram I have no triple x or B499
I can not find, can you help me please?
Thanks,

BIOS update failed this means that ROM module (where the BIOS is stored) isnt flashed properly.
As far as I know such issue could be resolved by flashing the ROM module again using Toshiba BIOS crisis disk.
I guess Toshiba authorized service provider own such crisis disk and could reflash the ROM

Mac Mini will not boot after Security Update 2008-007

Hello,
A G4 Mac Mini machine I was asked to take a look at will not boot after the owner (succesfully) installed Security Update 2008-007 from Software Update. Booting always hangs at the blue screen after the Apple logo, and booting in verbose mode reveals that WindowServer is crashing repeatedly. Permissions and filesystems have been repaired, PRAM reset, etc. Safe boot also exhibits the same problem, but it is possible to boot to single user mode. Hardware checks out fine with diagnostic utilities.
Any suggestions on how to fix this? Unfortunately, backups are not available (it's not my machine =).

Hi Arkku , and a warm welcome to the forums!
I'd certainly give Sig's advice a try first.
If that should fail...

"OK, restart your computer, hold down Command-s and type in the following:
/sbin/fsck -fy Enter
/sbin/mount -uaw Enter
rm /var/db/.applesetupdone Enter
# The rm command is the remove command which deletes the file.
# Robert: I'd rename the file via: mv /var/db/.applesetupdone /var/db/.applesetupdone.old
reboot Enter
Once you've done that the computer reboots and it's like the first time you used the machine. Your old accounts are all safe. From there you just change all other account passwords in the account preferences!!

HP Pavilion 15-n268sa will not boot after windows update (windows 8.1)

After a series of windows update (windows 8.1) my HP Pavilion 15-n268sa will not boot up, no fan noises, no lights no nothing.
I have tried a "hard reset" a number of times with no success.
When the battery is present the white LED flashes 3 times when the power button is pressed.
Please please help.

Hello Cuffy,
Welcome to the HP Forums!
I understand you notebook will not boot after a series of Windows updates.
Can you tell me if you are able to access the HP Recovery Manager by repeatedly tapping the F11 key while the notebook turns on? If you can access this, try doing a system restore to before you installed the updates. If not I would suggest you go through this document: Computer Does Not Start and the LEDs Blink or the Computer Beeps.
If it's the Caps Lock light that is blinking this document will tell you exactly what the error is (spoiler: 3 beeps is a memory failure). This could also explain the failed updates. The updates are stored in the RAM before being applied to the operating system.
You can try reseating the RAM, or using only 1 of the RAM cards, as you have 2x4GB cards. If it still doesn't work with 1 card, try the other card to confirm it has failed.
You can replace defective cards via HP Phone Support if covered under warranty or at the HP Part Store if not covered. You can contact HP Technical Support at 1-800-474-6836 in North America. For all other regions click here.
Hopefully this information helps!

Help Please - X200 will not boot after Bios Upgrade - keeps asking for power on password

Hi there,
I am new to this forum and please let me say a big Thank You for your help in advance.
I am using a lenovo thinkpad x200 running windows vista with service pack 1.
The laptop has always been running fine and has never given me any issues. Unfortunately, all this came to an end yesterday when I ran the system assistant which did a round of updates and it prompted me to reflash my bios.
I did what was instructed and closed all open applications and after the laptop restarted, there was a noise from the harddisk (the sound was basically like what happens if the harddisk suddenly loses power). Then, all i got was a black screen, no harddisk acitvity with only the power cable LED and another LED (with the shape of a N tiled at 20 degrees) on.
I searched the forum and did what was suggested in this entry: http://forum.lenovo.com/t5/X-Series-ThinkPad-Laptops/Blank-screen-after-Bios-Upgrade-on-X200/ta-p/29...
This is what I did so far"
I turned off the power, took out the backup battery and waited for about 30 minutes (repeated this step several times, also removing the harddisk) but to no avail.
I removed the RAM and tried booting and there was that characteristic beeping sound.
I replaced the RAM, redid the CMOS clearing, and now there is the Lenovo startup screen. However, there would be an error code 0271 (no date time) and 0251 (something about default configuration). Then, these disappear and all I am left with is the Bios Power On password prompt. Somehow no matter what I type nothing can be input into the field (and I did not create any password as far as I can remember).
I redid the clearing for the power on password by removing the backup battery as suggested at the bottom of this page http://support.lenovo.com/en_US/detail.page?LegacyDocID=migr-59377 but it is no use. Each time I restart, even if I press the blue Think Vantage button or F1 or F11, I still get the same 0271 and 0251 error messages and am left with the power on password prompt.
I am really desperate as I really like my lenovo x200 and there is important data on the laptop. I would appreciate any suggestions on how I can solve this. Its amazing how a simple update can turn into such a disaster. Now i know i should never upgrade or update my Bios (or at least proceed with extreme caution).
Anyone can provide some help to get my laptop workin again?
Thank you very much,
Mark

try reflashing your bios?
