Hello everyone!
I have a surface pro 4 (1724) with corporate management set up (in this case, I understand it's called SEMM). In the operating system installer (Pro version), after connecting to Wi-Fi, it asks me to enter the company system. If I don't sign in, it won't let me continue (similar to enterprise enrollment on chromebooks). This can be avoided if I install the Home version instead of Pro, and then upgrade to the pro version, but this is not very elegant. I would like the machine to be as it should be in factory condition. That's why I would like someone to remove this restriction...Yesterday, 06:39 AM -

TV: JVC LT-43C888 (purchased in 2018). This is a smart TV with Netflix, Youtube, Freeview and other applications via 'Viewd' app store
Problem with TV:
- Netflix stopped working so i tried to do factory reset from the TV menu.
- I confirmed on-screen but the factory reset did not happen even. It did not take me to 'first-time installation' screen as mentioned in the manual.
- After waiting for some time, the TV went into a boot loop.
- JVC logo comes on the screen and LED light flashes for some seconds, then it reboots again and the same thing happens

Hey folks, I have this iPad Pro 12,9" 4Gen A2232 here with no charging issue. The main fault was a crossed pins / faulty USB charging port due a bad cable.
So I started to replace this parts:
- replaced usb-c port -> no result
- replaced battery -> no result
- replaced usb-c chip CD3217B12A -> no result
- replaced 343S00326 -> no result
- replaced 343S00327 -> no result
- replaced 343S00328 -> no result
I have no more ideas for this issue. There is no short on the whole board, and the iPad is working fine...Today, 05:37 AM -

Hello. Coming to you from the laptop forum. Have a client with the Fortinet 50E that has 320 Mbps as internet input speed but only 20 Mbps output on each and every downstream port (using FAST.COM to benchmark).
Reseller is stating the Fortinet is 'worn out' which does not sound logical at all unless the flash memory is 'worn out'. They, of course, want to sell another + onsite installation fees.
Can anyone share feedback on this unit? What can cause this sluggish behavior. From our knowledge, this device is snooping on the traffic to halt viruses / hack attacks, etc....04-24-2024, 12:51 PM -

Hello everyone, I have a Lenove Thinkpad X201 tablet that always worked fine, when I turned it on yesterday the power and hd leds lit up for a moment and then slowly went out.

Hi everyone. An HP X2 1012 G2 came the other day. The problem was that the device drained the battery while off. I checked and saw the current is 0.2 before start. I went and checked parts on the MB and saw that the JHL6340 IC that is responsible for controlling Type-C gets hot. Everything worked fine and I checked charging and data of type-C both were OK. I went ahead and replaced the JHL6340. Now it does not get hot, no current before start, charging is OK, but the data of type-c is lost. I mean any type-c device like flash memory or hdmi adapter etc. do not work. I tried another jhl6340 and...Yesterday, 03:34 AM

Looking to up my game a little bit, but these programmers seem a bit daunting.
Trying to get a device for EMMC repair, and it's very difficult to lookup all the words to find if I'm on the right track lol.
Trying to reprogram EMMC on Sony/Hisense mainly but would like to hit a few other brands.
My question is would either of these work? And is there a specific card reader I need for TV emmc? There is like 10-40 additional pieces that I can get but not sure what I actually need for my application only.
I may do eeprom as well. Can someone point...04-21-2024, 08:18 AM
