this chapters should be talking about the tools, modules, sensors, microcontroller, and the process u used in making the device. arduino microcontroller is mostly used for this, coupled with temperature sensor, fans and and a heat element. if the hardware has been constructed, you have to ask the engineer for all this information also the sensor names and model number. but if you cant reach the engineer, you might have to simulate this using proteus, to make sure the c++ codes are correct. the methodology will also contain the shematic too. you can use proteus for that. the project is straightforward.

Good morning. For those who want to learn automation. I have arduino kits available at 20k. . It come with free tutorial too. Please call or whats me 08187469738

The Arduino starter kit contains all the components to get a beginner started, check pictures for details. you do not need a physical teacher to learn Arduino. I have already compiled all the tutorial you will need to get started, I will send you a link to download them for free, the file is 22mb, so u need little data to download it. I am also an experienced Arduino engineer, so I will be available to give you directions, materials, video links, and also answer all your questions for free. Call or whatsapp me 08187469738

Arduino kit for both beginners and advance user. Available. Call or whats app me 08187469738

Elvis778:

So I should re update with a different windows 10 OS?

Yeah use a different OS. Don’t update, clear all file. U can backup if u have important files

Elvis778:

i5 62bit

the OS u used might be corrupt. reload with a different OS

I just upgraded my PC to Windows 10(from Windows , when I open the start menu and try searching for apps, I realize my keyboard doesn't work on the search bar(including Virtual keyboard), even when I open settings and try to search for an option using the search bar, my keyboard doesn't work there too,...but the keyboard works fine in every other package including MSoffice. Please, does anyone know how I can resolve this?

What is the system model and processor

McChizzy:


Hello Adewale, my system has the same issue with the no bootable device showing and also the f1 and f2 buttons not working. I have even tried to install a ssd drive in it but same thing is showing even after loading windows on another computer onto the drive before installing in my computer.
Any ideas?

Problem might be related to bios

Sola2016:
What can I do to my Dell laptop it always write video tdr failure and it will not boot up to window

This may be drivers related. Reloading your OS might solve the problem.

xristos:

done ..still d same.
and its not just one usb port...all d ports.

I will need to see it for further diagnosis

xristos:
guru here is my problem..ive been using this hp for 2yrs now no issue ..core i5 x360 8gb.. suddenly after the last shutdown i noticed it cant startup again...it freezes at please wait.
i discovered it will only work normally when any USB is plugged..either charger or flash.
but immediately u remove it...it hangs...until u hard restart..
it only works with usb plugged.

Try reloading the OS

lahizak:
Hi. Please my hp laptop suddenly went black. I have tried had reset. Doesn't work. I can see shadow of contents working on the screen but it as if the light went out and everything else is working. No sign of broken screen. Please what should I do?

Back light issues are either caused by faulty screen, faulty signal cable or faulty motherboard. Call or whatsapp 08187469738 for further assistance.

I tried fixing my charger cable and it seems to have spoilt my motherboard. How much do I need to fix it?

clydecarson:

Goodmorning y’all,my hp laptop trips off when I disconnect the charger even with the battery being stucked at 83..please what do you think is the problem and the solution??thanks



I feel it’s the fan I may be wrong

If it trips off immediately after removing charger. Try replacing battery first

Please brothers and sisters in the house... I have one HP elite book 6930p laptop that has the following problems.
I want to upgrade to windows 10 from windows 7, but the DVD plate is bad
Some parts is the keyboard aren't working, and I wish to get a small external keyboard
I also need to get a battery for the system

Please I need ideas on how I can upgrade to windows 10 with flash drive, and how much can I get a small external keyboard.. I want to know the price because I have little cash.

Both of you are right,I believe adewale was talking about charging port.

The charging section is one of the most complicated section on the laptop motherboard.

You can get charging related issue from the charging port, VIN section, charging circuit, sio and battery.


On hp motherboards there is AD_ID (adapter identification) this voltage comes from the charging port to the sio chip,if this line is faulty,you might get fault of no power or laptop charge when it off but doesn't charge when it is on.

For Dell you have the ps_id , this volt comes the SIO chip to the charging port,now if the charging port is faulty,it won't communicate well with the charger.
If the port is faulty or the ps_id line is faulty you will get fault like adapter type UNKNOWN on the Dell BIOS setup instead of the stating if it is 45w, 65w etc, of course you will get plugin charging on desktop,this is charging issue too.

If there is MOSFET leakage in the VIN section it can also result to charging issue, if battery is bad it will definitely cause charging issue,if smclk,smdata and temperature line is faulty, you can get battery not detected fault, plugin not charging, battery icon not showing etc , sometimes rewriting the BIOS chip can solve charging issue especially if the duty circle is not normal, sometimes replacing the SIO chip .

Charging circuit starts from charging port or battery connector depending on where you're getting your input voltage and in some motherboard, they are detachable.

Now if your charging port is detachable and it is bad, there by giving you charging issue,if you connect it to another same board,you will get the same issue.

You have said well brother. We can even extend charging to the charger it self. May be he meant charging port sha. Because there is no way u will ever find the chips that makes up a laptop charging circuit on a sub board. They are always on the main motherboard. When i say charging chips, i mean the first two MOSFETs, the third MOSFET for battery, the ic that switches the MOSFETs, the super IO ic etc. You will never find them on a sub board.

Adewale1603:
some charging circuits are attached cable with connector, same as some usb ports, not all are on the motherboard directly

Kindly name one system (brand and model) that has it charging circuit outside the motherboard

MizterAccurate:


Thanks senior man. One more question bros;before the laptop went dead and i was advised to change the board,it had charging issues(it charges only once in a while) will the problem go away with changing the board?

It will charge perfectly. All charging circuit is on the motherboard .

MizterAccurate:
Hello bosses,please around how much should I budget to replace motherboard for dell E6410.
