Please don't steal my answer!!
Option 1 (new x).
Note (Original):
1 In safe mode, the effect is even better!
2.All the software to be used below should be installed or upgraded to the latest version to ensure the effectiveness of use.
3.It is not antivirus, and the following methods can be used directly. If the effect is not good, first kill it with a high-quality antivirus software (such as Kaspersky) in safe mode, and it is best to use 360 Security Guard as well, and then use the following methods.
Use 360 Security Guard's "Trojan Horse" - Full Scan". Kill and restart. )
You don't have to use all of the following methods, you can try them one by one. Sometimes, just the first one works.
One. Close the browser, open the "System Repair" of the new version of 360 Security Guard, scan it, and then click "One-click Repair".
Then use the 360 first aid kit (360 Security Guard's "Function Encyclopedia" is available.) If the 360 security guard is not installed, a separate first aid kit can be installed. Follow the steps:
"Start First Aid" first; After scanning, restart; Then click "System Repair" (you can select all of them to Repair Now". Next, click on "DLL File Recovery", add the missing DLL file that the system detected during detection, and then click "Repair Now". Repair Network is a case-by-case decision to fix or not.
When you're done, you should restart. 】
Two. Scan with 360 Security Guard's "Clean Plugins" to clean up malicious plugins. When you're done, you should restart.
Three. Use Windows Cleanup Assistant (from the web**). After scanning (if you sweep things out, check them all and clean them), then use Fault Repair (select all), and then right-click on the desktop to refresh. Works well in safe mode.
You can also consider using the Kingsoft First Aid Kit [Tick the "Extended Scan", after point scanning, if there are items that can be repaired, after selecting all, click "Deal with it immediately", and restart it after finishing. 】
You can also go down to an IE restoration expert, or a Yahoo ie restoration expert (there are also people who use Huangshan restoration experts). When you're done with it, try again: click on the top of the page Tools - > Internet Options - > change the homepage to what you want.
2.After installation, click on the one-click repair. After sweeping out the thing, the dot is processed immediately.
Emphasis ---1In the repair, when there is a prompt in Kill Soft or 360, please click Allow. Restart the computer if prompted to restart during operation.
2.When the effect is not good, look at the three points in "Attention". 3.
After that, if the effect is not good, you can also consider system restoration (choose a restore point).

The computer you use must be from the Lenovo Yangtian series, and you accidentally turned on the "kill switch". If you go to the front panel of the machine, there is a red place that can be wrenched, push it up hard (so that the switch is no longer left in the place marked "safe"), and the next time the system kernel will not be intelligently repaired.

I also didn't think it was right at the beginning, and finally it was the state of the burning of the royal continuation of the use of the section, otherwise you reinstalled it Lenovo is not a sail rock with a mounting disc (green) will not install me Q

This kind of machine is recommended that you still send it to the repair station to repair, if you have a strong ability to do it yourself, you can turn off the corresponding safety switch in the BIOS, if you can't, or send it to the repair station for maintenance.

The computer does not have an 11-pin COM port, only a 9-pin COM port.
Pin definition for 9-pin com:
1 Carrier Detection (CD).
2 Accept Data (RXD).
3 Sending data (txd).
4 Data Terminal Ready (DTR).
5 Signal ground (SG).
6 Data Ready (DSR).
7 Request Sending (RTS).
8 Clear Send (CTS).
9 Ring Indicator (RI).
The COM port (COM port) is a serial communication port. The com port on the microcomputer is usually 9 pins, but there is also a 25-pin interface, with a maximum rate of 115200bps. It is usually used to connect mouse (serial port) and communication equipment (such as connecting external modem for data communication or CNC machine interface in some factories).
Generally, there is only one COM port on the outside of the motherboard, and the nine-hole output terminal (trapezoidal) behind the chassis and the parallel port together is the COM1 port, and the COM2 port is generally led out of the pins on the motherboard. The parallel port is the one with the longest trapezoidal port.

Look under CMOS and there should be something disabled.

This may not be able to be turned off.
One: Press F1 basically because the battery in your computer is dead, you can dig it out and put it back in for a while. (If it doesn't work, you have to change the battery) The second reason is that your machine may not have a floppy drive, or the floppy drive is broken, but your BIOS also detects the floppy drive, so it prompts you to press F1 to enter the system every time. >>>More
