I have three Microsoft Surface Pro 5 model 1796, with all cracked screens.
Have bought from Aliexpress three new screens, the part numbers from my and the seller are the same:

Bad working China screen part number:


Good working own screen part number


Error I get with the bad working China screen:


No error with the good working own screen:



All the three China screens (all the same exact part numbers) produce the same error in Device manager. Have also performed a clean installation...

Apologies if this is in the wrong section but being a car alarm siren that makes noise i thought it be best to put it in the audio section.
Had weird alarm issues where siren made a strange noise: https://www.youtube.com/watch?v=ZjsqndhionU
took siren out of the car and checked it out and pics attached seem to be the source of the issue.
shockingly the alarm still makes its normal sound if i trigger it manually so speaker seems to be intact.
getting a replacement is gonna be next to impossible, its a Toad Ai606 which is no longer in production and cant see to find a replacement...

Hi everyone,
Do any of you know of websites where you can buy laptop screens at low prices, other than eBay or AliExpress? Because sometimes i have screens that are too expensive to recondition and so buying a laptop for parts is cheaper. I'm located in France.
Thank you.

This house has a Honeywell Accenta G3 alarm system. If the main unit loses power for any reason, the external siren sounds - even if the alarm is not even armed! Entering the code to disarm it is not an option as the keypads are completely dead when the power is out.

I presume this means the backup battery inside the box has failed, but I can't get in there and replace it without also setting off a tamper alarm! Is there any way to disable the tamper alarm so that electrical work can be carried out with the power off? Or a way to replace the backup battery without setting off the...

Good day to all. The bite alarm drains 9-volt Krona batteries. Current consumption when switched on is about 50 mA. I wiped the board from oxides, I will attach a photo (on the board there is a j3y transistor and a 7533 stabilizer, the microcircuit is erased = (the 3.3-volt stabilizer heats up weakly. I replaced it, nothing changed. I unsoldered the microcircuit, the consumption disappeared. The resistance on the pins of the unsoldered microcircuit from the point clockwise is more than 2 megaohms, the 11th leg is presumably ground. I warmed up the microcircuit, the consumption does not change....
