Lenovo Thinkpad notebook power indicator is on, the screen does not light up the reasons and solutions:

1. Use a multimeter to check whether the socket is normal and whether the power supply voltage is 220VIf the mains voltage is abnormal, it is recommended to replace the use environment test.

2. Use a multimeter to check whether the output voltage and current of the power adapter are consistent with the labeled. If the gap is very large and the mains voltage is normal, it can be judged that the power adapter is faulty and the laptop power adapter needs to be replaced.

3. If the above checks are normal, remove the laptop battery and do not connect an external adapter. Press and hold the power on/off button for 5 seconds and repeat 3 times. After releasing the residual charge of the notebook, plug in the power adapter separately and power on for testing.

4. If the fault persists, you need to plug and unplug the notebook memory. Replace the memory slots.

5. External monitor test, check if the external monitor is displayed, if not. It may be a hardware failure and needs to be sent for repair.

6. If the external display is connected, the laptop screen is not displayed. Then it could be a faulty backboard. Causes a fake black screen. It needs to be sent to a service station for repair.

In this case, it is directly related to the hardware, and it is recommended that you perform the following operations:

1. Remove the battery on the back of the notebook, connect the computer with only the power adapter, and try to turn on the computer, if the boot is normal, then it is caused by poor battery contact or battery failure.

2. Only use the battery, do not connect the power adapter, if the boot is normal, then it should be caused by a problem with the power adapter or a short circuit in the power interface of the notebook.

3. Unplug the power cord, remove the battery, and press and hold the power button for 30 seconds without letting go. Try to boot up, if the boot is normal, then it is only caused by the abnormal BIOS of the motherboard.

4. Unplug the power cord, remove the battery, open the back cover of the memory, plug in and unplug the memory, wipe the gold finger part with an eraser, and plug it back in (don't reverse it).

5. If the above operations cannot solve the problem, it is recommended that the notebook be sent to the maintenance center for testing.

The feature you're talking about is Lenovo's one-click restore function. If you are the original system, you will divide the recovery partition on the hard disk without providing a recovery disc, and as long as you have the recovery partition still there, you can restore it to the system when you bought the computer. In general, only the C drive will be recovered, and the other partition files will be present.

The Lenovo Thinkpad-R61 notebook cannot be turned on, you can check it as follows.

1) First remove the battery, unplug the power plug, press and hold the power button for about 5 seconds, then plug it in to see if it can be turned on, if it still can't be turned on, continue the following steps.

2) Remove the battery, unplug the power plug, and open the back cover screws with a Phillips screwdriver. There is an opening on one side of the cover, and the cover can be removed by gently cocking it along the opening with a screwdriver.

3) After removing the cover, find the memory module, and use a screwdriver to gently remove the clips on both sides of the memory module, so that the memory module can be released. Gently remove the memory module and wait a few moments before putting it back on.

4) Cover the cover plate in reverse according to the disassembly method, install the battery, and turn on the power button to restart.

You can reset it first and take a look at the external battery: After powering off, unplug the power adapter and battery, then press and hold the power button for 30 seconds, then connect the power adapter and battery, and turn on again. Built-in battery or dual battery:

Turn it off, unplug all external devices (including the power supply and external battery), and then find a small pinhole on the underside.

Dear Lenovo users, hello!

In this case, it is recommended that you use the power adapter alone to connect the machine to try it out to see if it is normal, and then update the power driver. If the power adapter is used alone, it is generally the power interface or power adapter that is abnormal, you can replace the power adapter of the same model of machine to test it to see if it is normal, and then go to the service station at a convenient time to let the engineer help you detect and repair the machine.

Drive lookup. Service station address inquiry.

For hardware problems, you need to use an adjustable power supply to actually look at the boot current, etc. After ruling out the power adapter is no problem, it is a hardware problem with the motherboard, which needs to be actually checked and repaired, and it can generally be repaired.

Most of the questions you need to look for are:

1. Power adapter.

2. Battery. 3. It's more troublesome, the motherboard.
