• Haha de câte ori am pățit așa ceva , mai ales la plăcile de bază din tabletele vechi…cu placa desfăcută era in funcțiune când puneam șuruburile, în scurt😂😂😂

• I own a Lenovo Legion 5 Pro laptop. Unfortunately, the battery has become damaged, so I've removed it from the device. I'm considering using the laptop by keeping it plugged in all the time. I'm concerned about potential damage to the laptop components over time since I don't plan to replace the battery and use it without a battery. I mainly use the laptop for 3D work, so it's on all the time. So , do I have to face any issues if I use like this for years? I appreciate your response. Thank you.

• Did anyone happen to forget screwdrivers, or other tools inside electronic equipment when repair??

• This is genius… I go to buy 3 black tapes

• We even insist our internal customers give us their power adapter just in case of any issues being caused by that!

• How to repair pci problem?

• please help . ideapad flex 5 windows and bios firmware update after no display

• I learned don't forget foil.

• Hi sorin i want to ask what model of your top view camera.thanks

• Sorin, this doesn't make sense because your previous vid shows the laptop was complete and had foil on the back of the board. You repaired the charge port and everything was working. So why is the foil missing on the back of the board now? Or was that a different laptop but same brand from many months/years ago with a similar broken charge port where only the motherboard was sent?

• It was a mistake to take just the motherboard. When doing laptop repairs ALWAYS ask customer to send laptop complete WITH power supply. This has been brought up several times in the past. Maybe now after being bitten a few times it's time to actually do it ^_^

• Another lesson learnt, something so trivial could mess up a good job. The manufacturer put it there for a purpose and it's always best to put it back as it came out. Thanks Sorin!

• Soak the whole board into hot glue

• One of the main reasons we tend to avoid partial repairs at my work to prevent the machinery from comming back after repair for warrenty, since a lot can go wrong on the customers end.

• Plastic foil is generally used to insulate components, prevent short circuits, and as an extra bonus, may also protect the motherboard if you spill a drink on the keyboard. So, if the Plastic foil is off the laptop will be shorted and won't turn on!

• Nice ! ty Boss!

• Great job! Thank you. Quick question: when you tested for short your PS clicked – I thought your PS was modified to remove short protection… will it still 'click' when a short is detected?

• The customer must pay a fee.

• Where is the board protection? Has a black tape on the cpu side and one covered with aluminium on the ram side. I repaired d14 today, same problem, broken usb-c port. I will post a photo on discord chanel!

• The boss does it again🎉
