PlayStation 4: PS4 won't turn on (No light or Beep)

Sun, 05 Apr 2026 09:44:40 -0700

I have had my PlayStation4 since release and just recently it started to give me issues. The PS4 is connected to a working power socket and plug in correctly, however I can't get the PS4 to respond (turn on) in anyway. It won't turn on at all, I get no light or beep like others have. The PS4 won't turn on for the Controller or Disk input. Noting out of the norm changed so I don't understand what would have caused this. No falls, no power outages, no over heating. Any ideas? can this even be fixed?

MacBook Pro 15" Unibody Early 2011: Battery Can't be Detected and Trackpad settings missing

Sun, 05 Apr 2026 10:59:20 -0700

So I recently replaced the logic board in my Early 2011 MACBOOK PRO in an attempt to breath some life back into it. Previous symptoms were the screen coming out greenish with very pixelated apple logo then crash before ever reading login screen.

New logic board fixed that problem, got the computer running but a new series of issues has arisen:

1) originally the battery emblem had the grey X in it, and the power cord light is stuck green even though battery is not charged. Tried resetting NRAM/PRAM and the SMC, instead of fixing the issue the battery icon has disappear entirely. I also have tried running Coconut Battery which also does not detect the battery. Put a multimeter on the battery connection to the logic board and I am getting 3-12 volts on various pins (first thought was the DC in had gone bad).

2) Running High Sierra the settings menu Trackpad section does not detect the internal trackpad even though it is working. Instead it is stuck looking for a bluetooth magic pad. Trackpad works fine accept I can't change any settings and it does not recognize Right-Click. All other gestures work.

My question is, could this all be from a bad battery? Its like the computer thinks it is a desktop now the way the battery icon has vanished and it is looking for a magic pad. Im trying to avoid a 60-100 dollar battery unless I am sure it is the battery and not a module on the logic board, SMC, etc. Any recommendation are greatly appreciated for further testing or a definitive on what the issue is.

UPDATE: New battery has not fixed the issue. Battery is still not being detected by system settings or coconut battery. However, the logic board is drawing power as disconnecting the charger does not cause instant shutdown. System settings is still not recognizing the trackpad either.

I’ve reinstalled OS High Sierra from disk recovery to no avail. At this point I’m running out of options other than possibly a faulty logic board. I’m hesitant to call it that since the battery is providing power and the terminals on the logic board read 12v which would seem correct for a 10v battery.

Any other ideas on tests to run or hard resets are much appreciated. Only other hardware step that involes power is the MagSafe itself, which I may try to sneakily test one at a local Apple store before purchasing a new module. I’ll attempt to call iFIXIT regarding the logic board they sent me and see if they recommend trying another.

To recap: SMC and PRAM reset have not helped, reinstalling OD has not changed anything, Single User Mode fsck -fy has not repaired anything, replacing battery has only changed that the computer appears to be drawing power from the battery though not detecting it.

to be more specific, the battery icon will not appear. every time i change the setting to show battery percentage it resets the box to unchecked after a brief pause.

I've also tried reseating the RAM cards and the battery twice.

Braun Razor: Rechargable battery - replace Li ion with NiMH?

Sun, 05 Apr 2026 09:15:02 -0700

I have a Braun shaver that needs a new battery. Thankfully this one doesn't have a soldered battery, it has a removable AA. The one that came out is generic (red covering, manufacturer wasn't anything I'd ever heard of). It does say it's Li ion, though. Meanwhile, the only rechargeable AAs I have are NiMH.

As far as I can tell the only difference is the NiMH has a much higher capacity (2300 mAh compared to like 750 for the old one). Is there any reason to think a NiMH wouldn't work?

Intel NUC: NUC working fine for a few years, but suddenly no HDMI signal

Sun, 05 Apr 2026 07:53:35 -0700

Hi, my NUC7i7DNK worked fine for a few years as a media PC connected to a 75" TV. Now when I came home from a week vacation the NUC do not seem to give any HDMI screen signal any more. I have tried another HDMI cable, I have got another PC to view sccreen on the same HDMI port on the TV. Restart of the NUC does not help... When I restart the NUC the power LED blinks a few time and end up having orange continuous light. The TV seems to notice that the NUC HDMI cablle is connected (because that HDMI input nuber is showing n the TV but TV still says no signall). Disconnecting the NNUC HDMI makes the HDMI input disappaer from the TV screen. Connecting another PC it shows the screen on the TV. What error/fautt suddenly appaering can cause such behaviour?
