If you haven’t, try a quick search for “water pik wp450 batter replacement”. There are a couple of yewtoob videos that are on the top of the search results that appear to walk through the steps. Here’s the one I glanced at. Hope it helps!
I'm afraid you haven't provided enough information for a good reply\suggestion. Based on the provided info, it doesn't sound like it is making it to the POST. If that's the case, then it’s probably borked. As far as I know, if you can’t get into the BIOS then there isn’t much you can do aside from replace the motherboard. If you can get into BIOS, then there is hope! See what hardware the BIOS is recognizing and what it is not. It could be a simple harddrive swap or something like that that. /fingers crossed!
This may or may not be helpful but here is some info on the topic in case you don’t know: Get info about device unlock eligibility Why ATT unlocks can be challenging My first guess is, the phone was financed and there is an outstanding balance on it. Anyway, hope this information helps someone.
You can try checking the system files with a few utilities- perhaps something was borked during the update. From an administrative CMD prompt run: (1) sfc /scannow (2) when completed run: DISM /Online /Cleanup-Image /RestoreHealth (see https://www.windowscentral.com/how-use-dism-command-line-utility-repair-windows-10-image for a good description of the options) then reboot if any repairs were made\noted. (3) when completed, next run sfc /scannow again Another option may be to find the original drivers (like on the disk that comes with the machine) and try those as others have mentioned. You could even restore from a backup prior to the update install and see if the wifi works or not. There is a chance the wifi card itself is dead and the timing is just coincidence. Finally, here’s a link from others having a similar description of symptoms: https://answers.microsoft.com/en-us/windows/forum/all/problem-with-wifi-non-function-after-windows-10/62f8771d-98a3-43bd-9c0c-4c1dee782479?auth=1 I hope something here...
Hi Ron. First, I am not an auto mechanic- just a guy with the occasional busted knuckles. I would imagine that any foreign debris could cause an issue like this if it prevents the valves from opening\closing fully. It could allow gases to escape via the stuck valve during the combustion stroke. Maybe the debris is effecting the spark plug’s ability to ignite? I guess it’s even possible the bits change the fuel-air mixture since the cylinder’s volume has changed.
