First of all, don't panic. Disconnect the cord from the back of the pc and press the on button repeatedly to clear the system completely of power. Reconnect the power cord and see if the unit will now power on. If not, press F8 until you get a screen choice and once you do, choose "safe mode". Open the control panel and look for "programs" and from there "recent updates" and uninstall the most recent one listed. If that doesn't work, go back to safe mode and do a system restore and reset the system back to a time and date prior to the update.

U in deep doo. Update did not take for whatever reason.

Updating should never be attempted unless you are having an issue that requires the update. Otherwise, if it is working you leave the darn thing alone. Most of the time it is not uncommon to have hassles after updating.

You have learned a painful lesson - now you have to deal with it by reloading the entire machine if you have backups. You do have a backup, don't you? If not, the doo doo gets mucho deeper!!!!!!!!!

    Richie, I can't power on so I can't load the backup disketts. It a laptop, not a desktop.

    yipes - sorry about that. If I remember correctly there is some sort of reset for lenovo laptops when they just do not turn on. I googled it and it worked for me on my daughters laptop. But now I am thinking tht it was powering up and just stuck.


    U might also consider removing the cmos battery and clearing the cmos for about ten minutes or so, hold the power button also for that time, then reinsert the cmos battery, cross your nut sack and hook it up to your power pack. If still does not work you may have a hard ware issue. Google "T520 will not power on after win 7 update" and check out the listings - u might get lucky.

    Also make sure that your battery is good as well as your ac power supply.

Reset ecu on Nissan hardbody 2006 model.stoped it at home,now wont start.maybe for second or two.Nats light not working on dash. keys still opening doors,enjin turning,does not start.enjin check light


Give this a try.....Timing is not as critical with this method...no stop watch needed. Just count in your head...one-one thousand, two-one thounsand, etc, or usestop watch. The most critical step is step #3....wait 10 sec, instead of 7.



1. Ignition "ON", count to 3.

2. Depress/Release pedal 5 times...hard and fast.

3. Count to 10 (not 7!) and fully depress pedal

4. Count to 12 (SES should be blinking), release pedal

5. Count to 10, depress pedal

6. Count to 10, release pedal.

7. Turn off ignition, then 81377951893%26mt_id%3D570%26mpre%3Dhttp%253A%252F%252Fwww.ebay.com%252Fitm%252Flike%252F181377951893%26mid%3D446528%26sdc_id%3D%7Bsdc_id%7D&DealName=12v%20Electric%20Push%20To%20Start%20Engine%20Ignition%20Button%20With%20Red%20Led%20Light%20Up&MerchantID=446528&HasLink=yes&category=0&AR=-1&NG=1&GR=1&ND=1&PN=1&RR=-1&ST=&MN=msnFeed&FPT=SDCF&NDS=1&NMS=1&NDP=1&MRS=&PD=0&brnId=2455&lnkId=8070676&Issdt=150102050536&IsFtr=0&IsSmart=0&dlprc=19.99&SKU=181377951893">start engine.

Doesn't enable virtualization


To determine whether your PC supports hardware virtualization:

Step 1. Does my PC have a CPU with support for hardware virtualization?


Download and run the Hardware-Assisted Virtualization Detection Tool

If you receive the message This computer does not have hardware-assisted virtualization, your computer does not meet the hardware requirement for Windows Virtual PC, but you can still use Windows 7 XP Mode by running this hotfix. Be aware that XP Mode will run much better if hardware-assisted virtualization can be enabled.

If you receive the message Hardware-assisted virtualization is not enabled on this computer, go on to Step 2 below.

If you receive the message This computer is configured with hardware-assisted virtualization, download and install Windows Virtual PC and Windows XP Mode.

Step 2. Does my PC BIOS support hardware virtualization, and is it turned on?

Instructions to turn on hardware virtualization in your PC BIOS are specific to OEM models. It is important that after changing your BIOS settings the PC is completely shut down at the power switch before restarting so that the new BIOS settings can take place.

Examples for some models of some computer manufacturer's BIOS settings are below:

Sample instructions for your PC

Expand all

Dell systems

Depress the F12 key when boot menu text appears at startup

Select BIOS setup and depress the Enter key

Using the mouse, expand the Virtualization Support menu item by clicking on the plus to the left of Virtualization Support and select Virtualization

Check the Enable Intel Virtualization Technology checkbox

Click Apply

Click Exit

Fully shut down (power off), wait a few seconds, and restart your computer

HP systems

Depress Esc key when prompted at startup

Depress the F10 key to Configure BIOS

Scroll to System Configuration using the arrow keys

Select Virtualization Technology and depress the Enter key

Select Enabled and depress the Enter key

Depress the F10 key to save and exit

Select Yes and depress the Enter key

Fully shut down (power off), wait a few seconds, and restart your computer

Lenovo ThinkPad systems

Depress the blue ThinkVantage key when prompted at startup

Depress the F1 key to enter the BIOS setup utility

Using the arrow keys, scroll to Config and depress the Enter key

Scroll to CPU and depress the Enter key

Scroll to Intel Virtualization Technology and depress the Enter key

Select Enabled and depress the Enter key

Depress Enter key to continue

Depress F10 key to save and exit

Select Yes and depress the Enter key

Fully shut down (power off), wait a few seconds, and restart your computer

Acer

PCs capable of supporting Windows XP Mode have already been enabled and do not require additional configuration.

Asus

PCs capable of supporting Windows XP Mode have already been enabled and do not require additional configuration.

Samsung

PCs capable of supporting Windows XP Mode have already been enabled and do not require additional configuration.

Panasonic

Depress the F2 key when boot menu text appears at startup

Select Advanced menu in Setup Utility

Change "Intel Virtualization Technology" setting from Disable to Enable

Depress F10 to exit Setup Utility

Select Yes in confirmation menu

Depress Enter to exit confirmation menu.

Please note the instructions above may not work in all cases and consulting with your computer manufacturer may be necessary. Additionally, we expect hardware virtualization to become more available when Windows 7 is shipped, particularly in business-class PCs. For those PCs that come pre-installed with Windows XP Mode we recommend the computer manufacturer turn on hardware virtualization before shipping the PC.


Once you have confirmed your PC supports hardware virtualization
Download and install Windows Virtual PC and Windows XP Mode

hope this helps

The standard PIN code can be changed following thesequence below:
i) Type in to the keypad **
ii) Type in to the keypad the "existing PIN code" then *
iii) Type in to the keypad 92 * "new PIN code" * "new PINcode" #
Programming Remote Keys to the System:
Remote keys can be added or removed to/from the systemfollowing the sequence below:

iii) Type in to the keypad 91 * " the number of keys to beused" #
iv) Press the first remote key button until bleep sounds,release and press next key. Continue until all
keys have been taught to the system. Note the maximumnumber of keys is 4 and all keys required
to operate the system must be taught during this operation- any key not included will no longer
operate the system.
Full Programming, Diagnostics and Features
This section contains all the information that the dealersuse for programming and diagnosis of
the Sigma M30 alarm system, using the MK1 keypadprogrammer.. Programming can also be carried

It is important the keypad buttons are not pressed tooquickly-
Each time a button is pressed the LED on the keypad willflash once as confirmation. The next button should
not be pressed before this confirmation.
It is important the keypad buttons are not pressed tooslowly-

You must wait until the LED stops flashing and then startagain.
All programming functions are entered after typing * andthen the programming PIN code. The programming
PIN code is 17856.
To enter the programming PIN code, the alarm system mustfirst be armed and then disarmed using a valid
remote key. (Or keypad using the PIN code)
* 17856 * must then be entered within 30 seconds ofdisarming the system. This is then followed by a 2
digit function code, then another * and then sometimesoptional parameters as shown in the following tables.
It is important to remember the * key is used to separatethe various parts of the code like this:
* programming PIN code * function code * parameter #. The# key is pressed at the end of all
