Win11 vertical taskbar is finally here!

 tart11 was developed by Startdock and is specifically designed to customize the taskbar and start menu of Windows 11.

In Windows 10 and previous versions, users can freely adjust the position of the taskbar, but Windows 11 limits the taskbar to the bottom of the screen.

The launch of Start11 v2.5 Beta breaks this limitation, allowing users to move the taskbar to the left or right side of the screen, bringing a familiar operating experience to users who upgrade from Windows 10 to Windows 11.

Users only need to upgrade to Start11 v2.5 Beta, open the control panel, click the taskbar, select the taskbar position as the left or right side of the screen, and save the settings.

How to disable secure boot in Acer BIOS

 An ACER notebook does not have a button battery. When the notebook battery is used up or has run out of power after being stored for a long time, the system cannot be found every time it is started. The secure boot + UEFI boot is enabled by default. If it is Win8 or above, it can be started normally. Most of these notebooks should be installed with Win7. Win7 can also use UEFI boot but Secure Boot must be turned off to use it. It is forced to be enabled by default and is grayed out and cannot be turned off.

Press F2 to enter BIOS, go to Security, select Set Supervisor Password and press Enter to set a password.

Return to the BOOT option, Secure BOOT becomes optional, and Enabled is set to Disabled to close.

(Note: After changing the secure boot, you can set the password to blank, otherwise you will be prompted for the password every time you enter the BIOS)

HP TPN-C125, shut down automatically from time to time for maintenance!

HP TPN-C125, shut down automatically from time to time for maintenance!

I received a HP computer from my colleague, saying that it always shuts down automatically. He took it apart, cleaned the dust and replaced the silicone grease, but it still failed. The baking machine tested that the CPU and graphics card were normal and would not shut down automatically, but it turned off itself after working normally or standing there for a while.

Get the machine and bake it for a few hours. Test that everything is normal and it will not automatically cut off power. First of all, I wonder if it has something to do with sleep. If I turn off the sleep standby test, it will still automatically cut off the power. I wonder if the memory is unstable, then open the memory test tool and test it is normal; Because there is data on the hard disk, I am afraid to break the system, and I am going to test it in WIN10 PE. I just entered PE for less than 30 seconds, and the power was cut off. I tried it several times and it was the same. I wonder if the BIOS version is too old. I went to official website to download the latest online BIOS update. After the update, PE directly reported the error BIOS_ACPI_ERROR in blue screen, but the problem of power failure was still unsolved!

It seems that there is something wrong with the motherboard itself. Take a look at it!

Machine appearance drawing

Fuselage model: TPN-C125

Main board version number: A-C701P REV:1.0

After electrifying, the major power supplies were measured, and there was no abnormality. Then, touch with your hand to see where there was any temperature abnormality, and it was found that the temperature of PL14 inductor was particularly hot, which was the CPU power supply inductor. Because the baking machine takes too long, I’m not sure whether the CPU temperature is too high. After cooling the machine, I feel the temperature change of PL14 with my hands while turning it on, which is really a very fast temperature rise.

Replace all the upper and lower tubes, filter capacitors and inductors of this power supply.

Start the test again, the temperature of PL14 is normal, stand by for several hours, and there is no automatic power failure, so the maintenance is over!

Lenovo R7000 flower screen repair

Lenovo R7000 Blurred screen, modify the firmware (BIOS program) to enable the computer to start automatically when the boot.

Machine model: Lenovo R7000

Fault phenomenon: screen Blurred screen

Maintenance process: the Lenovo r7000 Blurred screen, which was sent for repair by peers, is very serious. It costs money when it is started, but it can enter the system. The colleague introduces that the customer is an office workernotebookComputer, peers themselves said that the graphics card may be broken, need to Repeat welding graphics card or replace the graphics card to solve.

Lenovo R7000 flower screen repair Figure 1.

Lenovo R7000 flower screen repair Figure 2.

Blurred screen is really serious for the interface of preparing to boot. I believe many maintenance engineers have encountered this kind of Blurred screen. The maintenance method must be to start with a simple method first and exclude the memory first. The Blurred screen caused by a (Dell Computer) memory two days ago is not much different from this.After clearing the memory, the fault still remains.Lock fault in the motherboard, remove the machine, take out the motherboard to see the CPU and graphics card.

Lenovo R7000 flower screen repair Figure 3.

Lenovo R7000 flower screen repair Figure 4.
Some years ago, the master who repaired notebook computers liked to use one of the moves is to heat SMD REWORK STATION Repeat welding first to see whether the display is normal. If the display is normal, it means that the display card Inveracious Soldering, and then go to Repeat welding on the BGA Rework Station welding plaorm. We can also try to heat SMD REWORK STATION Repeat welding, or Blurred screen, with BGA Rework Station Repeat welding still Blurred screen, and feel Blurred screen is more serious,It means the video card is broken.

This video card chip is more expensive to buy, to be honest, to help peers replace the graphics card, if there is no professional test equipment to test the graphics card chip, it is very easy to get hit.Finally, let the peer communicate with the customer, whether the office computer is OK or not, and the customer agrees that as long as it is repaired, it can work normally, and other things don’t matter.This machine has its own unique display, but because the display Blurred screen cannot be adjusted, he finally communicated with his maintenance friend, and he thought of a move. By modifying the firmware (BIOS program) to make the computer automatically use the display when it starts up, it can solve the problem of Blurred screen.

According to this maintenance plan, the BIOS was quickly flashed. After the test,no booting might not be installed because of the urgent test. I thought that there was something wrong with the BIOS program, and then the BIOS of the original machine was still no booting. After taking out the mainboard, carefully checking it, carefully installing it back, starting Blurred screen again, and then brushing the modified firmware, the display was normal.

Asus H110M-K mainboard Won’t Turn On repair

Asus H110M-K mainboard Won’t Turn On repair

Main board model: ASUS H110M-K main board

Symptoms: motherboard Won’t Turn On

Maintenance process

ASUS H110M-K motherboard, the fault is that it can’t be turned on. Measure VCC signal according to time sequence:

P_+VCCIO_EN_10 2V is normal;

VCCSA 0.96V is normal;

P_VCORE_EN_10 3.3V is normal;

P_VR_READY_10 is not normal without VCC;

Look up P_VRM_PGD_10.VCC is not normal.

Asus H110M-K motherboard Won’t Turn On repair figure 1.

P_VRM_PGD_10 does not have VCC. This signal is a PG signal sent by CPU power management chip ASP1401B, which shows that there is something wrong with CPU VCC. According to the time sequence, CPU power management chip will send PG when it receives EN and VCC. Let’s find out the conditions for generating VRMPWRGD.

1. VCC VCC 5V of 1.CPU power management chip is normal;

2.P_VCORE_EN_10 3.3V is normal;

3. Measure the VCC VCC of the driver chip of each phase VCC of CPU, and all of them are 12V normal;

4. P_VCORE_DRON_10 This is the signal used to turn on the driver chip. The measured value is 1.19V, which is obviously abnormal, and the normal value is 5 V.

Asus H110M-K motherboard Won’t Turn On repair figure 2.

P_VCORE_DRON_10 is a signal sent by the power management chip to the driver chip, and it will go through a 49.9-ohm resistor to four driver chips. Therefore, if the VCC is low, it is necessary to turn off the 49.9-ohm resistor between the driver chip and the power management chip one by one to see which resistor will restore VCC. If all the resistors are turned off, it may be that the power management chip is broken.Find out the fault point after a wave of analysis operation.

Measure P_VCORE_DRON_10 VCC again after disconnecting this resistor.

Asus H110M-K motherboard Won’t Turn On repair figure 4.

P_VCORE_DRON_10 VCC is back to 4.86V normal, which means that the driver chip of integrated display VCC is damaged, which leads to the lowering of P_VCORE_DRON_10 VCC. Replace the damaged driver chip NCP81166A(PU201).

ECS B75H2-M3 no reset auto power off restart repair

Lenovo CIH81M does not trigger.

The customer brought a Lenovo brand machine and said it was not turned on.

Get the hand power, do not trigger, measure the power supply, USB to the ground.

Seeing that the motherboard BIOS has been moved, I thought it was a small problem, but it was useless to discharge and brush the BIOS. There’s no way out. Remove the power supply from the side.

There are 12v, 3.3 and 5v, and that’s the problem.

There was no en in the test, but there was 3.3, and there should be 5 V. He just couldn’t find it. He read another big boss’s post.

The triangle tube on the left side of PC920 is controlled by en. If it is removed, it still won’t work. I planned to change the power supply IC, went to Taobao and asked Mr. Su, and the result was 25, which scared me to decide to remove it on the spot.

How about measuring the resistance of each foot? The resistance of G turns out to be 45, which is the same as that of S, so I understand. G passes S, after replacement. Exquisite, when I entered the system, I found that six USB could not be used.

Measure the safety tube 5 pin tube. One end is 5v and the other end is not, u54 u51

Take it down and connect it with tin wire. Don’t ask why you don’t replace it. Next time you burn it, it won’t be a big piece, just like the safety resistor O ohm.

Re-enter the system and solve it perfectly.

Therefore, be sure to ask about the customer’s use, phenomenon and recent operation, or you will take a lot of detours.

Also, don’t believe everything the customer says, burn USB at 12 V.

QUICK-GUIDE FOR TROUBLESHOOTING "NO POWER" ISSUE IN LAPTOP MOTHERBOARD

 In laptop motherboard repair, "no power" is a common issues that we always encounter.

This troubleshooting guide generalizes the basic steps to quickly isolate the "no power" problem:

• 19V must present at sense resistor or high-side mosfet (pin 5-8, drain)
• 3VALW/5VALW must be present
• RSMRST# and SLP_S5# must be present before or after power button is pressed
• Main rail (3V/5V) voltage must be present before or after the power button is pressed
• SLP Signals must be present

CHECKING 19V RAIL

Laptop motherboards incorporate a mechanism to protect itself in the presence of over-voltage or over-current. Over-voltage happens when the maximum voltage threshold acceptable by the motherboard is exceeded.  This value can often be found in the schematic or in the datasheet of the charging IC through the ACDET pin. Over-current happens when any of the filter capacitors and high-side MOSFET in the 19v rail becomes shorted or leaky, charging IC or MAINREG is shorted.

The sense resistor (PR303) is used by the Charging IC(PU301) - BQ735 to detect if current consumption is within normal operating conditions.  19V will not be present if this condition is not met.  This is the reason why sometimes you can measure 19v at the gate of  the two P-Channel MOSFETs (see PQ303 and PQ302).  The charging IC acts as a control switch that turns ON and OFF the 19V supply coming from the ADAPTER. 

If this circuit is normal, this charging IC reports its status to SIO via the ACIN pin with the presence of 3.3v.  Other charging circuit implementation requires 0v.

3VALW/3VLP

Always on voltage, specifically 3VALW must be present to provide 3.3v supply to SIO (see figure below), PCH, and pull-up voltage for SMB communications between charging IC, SIO and PCH. This supply is always present regardless of the ACPI states the laptop is operating. 

 The 3.3V supply comes from the LDO output of the MAINREG.  In this case, the 3.3V main regulator is an SY8208B IC or RJ4.

PU401 requires an input voltage of around 4.15V at pin 7 to enable its LDO output 3VLP.  If this is not present, then replace this IC.

RSMRST# AND SLP_S5# MUST BE PRESENT

There are a number of reason why RSMRST# won't come out from SIO. This could be a faulty SIO, corrupted EC firmware, missing 32.768kHz, missing 3.3VALW, busted EC SPI chip, open resistors or PCB traces,  etc.  

In the circuit example, you can measure the ouput through pin 100 of the SIO. 

It is also possible that the SLP_S5# is missing.  If this is the case, focus on RTC circuit and make sure the RTCVCC, INTRUDER#, RTC_RST#, SRTC_RST#, INTVRMEN have at least 2.3V-3.3V in them.  

SUSB#/SUSC#/SLP_S4#/SLP_S3#

If a power button is pressed, the signal will go through NBSWON# (other names are PWR_SW#, ON/OFFBTN#, etc.) and sent to DNBSWON# going to south bridge chip (PCH integrates both SB and NB).  If everything is normal, SLP_S4#, SLP_S3#  or (SUSC# and SUSB#) will have 3.3v. This signals will trigger SUSON (SUSP#, SUSC_EC#) and MAINON (SUSB_EC#) signals.

If SLP_S4# and SLP_S3# does not come out when the power button is pressed, you may need to reflow, reball or replace the PCH.

If SUSON or MAINON does not come out, then SIO is faulty.

QUICK GUIDE FOR FIXING "BATTERY NOT DETECTED" ISSUE IN ACER ONE 14 Z1402

 We would like to share some ideas for resolving issues in Acer One z1402 where battery cannot be detected by the system. The troubleshooting concept here may be applicable to other laptops with similar charging circuit designs.

SYMPTOMS:

• Battery is not detected in Windows
• Charging indicator does not lit

REPAIR NOTES:

• BAT+ is normal and BAT_SMBCLK and BAT_SMBDAT have pullup voltage of 3.3V.  Also, no activity were noted in the oscilloscope.
• Found an abnormal voltage reading in battery detector circuit, BAT_V = 0V
• Pin 3 of Q58 is 0v which means BAT_V is forced to 0v. Expected voltage at this pin should 2.375V for normal operation. (see image)
• Pin 2 has 3.3V which  should forces pin 6 and pin 5 to 0V. (see image)
• But actual voltage at pin 5 is 5v which makes it abnormal
• Further test indicates that D1-S1 junction is open which results in inconsistent reading of 5v in pin 5 and 0v in pin 3.
• Replacement of Q58 fixed the problem

Resolving cases like this can be easily fixed if every component will be checked for normal operation using datasheet or schematic diagram. However, analyzing the circuit and what voltage to expect as you test each pin of the IC is a difficult challenge. 

ACER V5-473 DAZRQMB18F0 W/ MISSING +5V_S5

 Let's suppose you are troubleshooting an Acer V5-473 w/ board code DAZRQMB18F0 and the voltage measurements are as follows: 

This circuit design is found in many laptops and knowing how to troubleshoot them would enhance your capability to fix many laptop problems such as no-power, auto-off and no display problem.

Voltage measurements were done after pressing the power button. Can you analyze the circuit answer the following questions?

• Based on the above voltage measurements, which component(s) do you think is the potential faulty component? Why?
• Let's assume that all voltage rails are normal but PR118 is open, what voltage can we measure at +5V_S5? Why?
• Let's assume that all voltage rails are normal but the drain-source pin of PQ22 is shorted.  What voltage can you measure at +5V_S5?  What will happen?
