Hello 4; IbE; 22 Oct 2020 'It warms my heart, to see a Motorola, with 6 Amps, under the hood.' I have 5 Amps now, and a 6' screen, and find this, a great blessing, in getting through my day. The 840 & 850 G3/G4 do not support charging via the USB-C port. The USB-C port on these systems support data only and charge out (charging a cell phone as an example). These systems support charging via the barrel AC adapter and the side docking connector (while docked to the Ultra Slim Dock).

My G4 Quicksilver went dead with the following symptom. I'm getting a new battery tomorrow, haven't tried that yet.

Hey all, I generally don't have a need to do this, and when I do, I can just get it from the BIOS or PXE boot. However, neither PXE booting or digging through the BIOS is showing me the MAC address for this specific model of computer (Dell 380).

It can be really confusing when you reach for your phone and find it turned off for no particular reason. You are sure that the battery is charged and no one else has turned it off, then how it was shut down? If your phone keeps turning off randomly, then it could be a hardware problem or a software problem. However, in most cases, you can easily fix it yourself. In this post, I will show you simple methods to fix your automatically turning off phone.

Hardware Issues

Usually, it’s a hardware problem when your Android phone keeps turning off but works fine when you turn it back on. Let’s see how you can fix hardware issues that are causing your phone to shut off randomly.

Does the Battery Fit Properly?

The most common cause of phone turning off automatically is that the battery doesn’t fit properly. With wear and tear, battery size or its space may change a bit over time. This leads to the battery getting loose a bit and disconnecting itself from the phone connectors when you shake or jerk your phone.

To confirm this is the problem, turn your phone on and shake it mildly. If this doesn’t turn it off, then grab your phone in one hand and mildly smack its back on the palm of your other hand. Make sure the battery side hit on your palm to put pressure on the battery. If the phone turns off, then it’s time to fix the loose battery.

The solution is rather simple. Take a tiny piece of paper and fold it in square wraps to make it a little thick. Now insert this paper at the bottom end of the battery opposite to the connectors. You will have to judge how much thick paper you need to make according to the loose space that is causing the problem.

If this doesn’t fix the problem, then it could be a problem with the loose back cover of the phone. In such a case, place that same paper on the back of the battery (between the battery and the back cover), and then put the back cover on. If you are able to make the space tight enough, it should fix the problem.

Defective Battery

There is also a chance that your battery may be damaged and improper current flow is leading to phone turning off automatically. Fortunately, it is really easy to see battery status on almost any Android phone using a secret dialer code.

Open up your Android’s call dialer app and enter this code *#*#4636#*#*. You will be immediately taken to phone details page, tap on “Battery information” here. In the battery information, make sure that “Battery health” is “Good”. If it is anything other than that, then you will have to replace the battery to stop your Android phone from shutting down automatically. If this code doesn’t work, you can also use the AccuBattery Android app to see the battery status. This app can show battery status and also help prolong its life. Although I doubt the later promise of this app.

Android Phone Heating Up

Additionally, if your Android phone is heating up too much, then it could also be the cause of random shut down. When the phone heats up to the point it could damage the components, it will automatically turn off. This even happens if you are not using the phone and it is just lying around.

There are many fixes to the Android heating problem and you can follow my extensive guide to fixing a heating Android phone to fix this problem.

Remove Phone Case

A bulky phone case or one that replaces your phone’s back cover with its own can also lead to making battery space loose. If you are using such a phone case, then use the phone without it to see if it fixes the problem.

Stuck Power Button

There is also a chance that the power button on your phone is stuck or malfunctioning and turning the phone off. Press the power button multiple times and make sure it is working smoothly. The button should feel smooth while pressing and also immediately come out when you release. If the button is stuck inside, then you can use a tweezer or something similar to pull it out.

Software Issues

If there is no problem with the hardware, then it could be a problem with the software of your Android phone. Below are some solutions to solve software issues that are causing your Android to turn off randomly.

Boot in Safe Mode And Delete Rogue Apps

To ensure that the problem is with the software of the phone, you should boot your phone in Safe Mode. Similar to PCs, Android phones also come with a Safe Mode that allows it to boot with least system applications and no third-party applications. During Safe Mode, a rogue application or a virus will not take effect, thus allowing you to find the problem.

The process of booting into Safe Mode varies from manufacturer to manufacturer. The most common way is to hold the power button to bring the power menu and tap and hold on the “Power Off” button until “boot in Safe Mode” prompt shows up. Confirming this prompt will restart the phone in Safe Mode. Holding the volume down button while the phone is starting can also open up Safe Mode, which is good when the phone isn’t starting at all. If this doesn’t work for you, then search online for the method to boot your particular device in Safe Mode to get an answer.

Once inside Safe Mode, check whether the phone is randomly shutting down or not. If the problem is fixed, then it must be a new added rogue application that is causing the issue. While still in the Safe Mode, move to the applications section in your phone settings and uninstall all the newly added applications. Make sure to delete all the apps after which the random shutdown issue arose.

Now restart your Android phone to go back in normal mode and see if the issue persists.

Remove Malware and Viruses

If removing the apps doesn’t help, then it could be a virus that may be automatically turning off your phone. Although there are many security apps for Android, but for this purpose, Avast Free Antivirus for Android should be enough. Install the application and it will automatically scan and delete any viruses that may be causing this issue.

Factory Reset Your Phone

This is a rather harsh option, but in most cases, it will solve all types of software related problems. If you are sure it is not a hardware problem and uninstalling apps and scanning for viruses didn’t help, then resetting your phone should fix this problem.

Warning: A Factory reset will delete all the data stored in your phone’s memory. Including contacts, messages, media files and applications stored in the phone memory. Make sure you have backed up all the important data before performing a factory reset.

To reset your phone, go to phone settings and tap on “Backup and reset” option. Here tap on “Factory reset phone” and confirm the prompts to start the reset process. It should take 5-10 minutes to completely reset the phone. During the reset, make sure the phone doesn’t get turned off as this can also brick the phone and make it useless.

After the reset process, you will again have to authenticate your Google account and a few other obligations. Your phone should work fine after the reset if it was a software problem.

Is Your Phone Working Fine Now?

The above steps should be enough to fix all types of hardware and software related problems that are making your Android phone turn off automatically. If the issue still persists, then you will have to take it to a technician or to the manufacturer if it is still under warranty. They should be able to fix it or replace the phone with a refurbished one.

Which one of these methods worked for you? Do let us know in the comments.

Reinstalling Mac OS 9 on a PowerMac G4 MDD

The PowerMac G4 MDD was Apple’s last Mac capable of dual-booting into both Mac OS 9 and OS X. The last of the G4 towers, this model was originally introduced in 2002, briefly evolved into an OS X-only configuration with FireWire 800 in 2003, then returned to the original design for another year.

Due to the need for some customers to run Mac OS 9 for several years after the introduction of OS X, Apple continued to sell this configuration online in parallel with the PowerMac G5 for over a year. They never pushed this option on the Apple Store but it was a consistently strong seller.

These machines came set from the factory to boot into Mac OS X, with OS 9 also loaded on the hard drive. No OS 9 installer was provided, rather that was available as part of the Software Restore CDs bundled with the Mac. The MDD uses a model-specific version of Mac OS 9.2.2, newer than what was included on the last retail OS 9 installer. You need the bundled discs if you want to reinstall a bootable OS 9 on this machine. (Note: only MDDs without FireWire 800 ports can boot into OS 9, models with FireWire 800 ports require OS X. The install CD I used is Apple part number 691-4078-A.)

I'm Getting Power Hungry..imac G4 Unlocked

Recently I was contacted by a client who was looking for just this. He had a dual 1.25GHz MDD with some older ProTools hardware, and preferred to run the software in OS 9 rather than OS X. The problem was his installation of OS 9 was unstable so he was looking for the original installer. Did I have a copy of this rare item?

Off-the-shelf I did not, but fortunately I knew what he meant and where to get one. My last job before running Oakbog full time was as IT Manager for a recording studio, and we ran ProTools hardware and software on these very Mac models! We had about 5 of those systems at one point, so I suspected there were plenty of CDs still buried deep in drawers. Fortunately there were, I contacted my colleagues at the studio and arranged to get a set of the install discs.

My client didn’t need Mac OS X, nor was he interested in first installing OS X 10.2.1 on his tower before restoring the OS 9 image. He just needed a bootable OS 9 System Folder. I suspected this was included on the set of four CDs somewhere, but it isn’t a Finder-visible file.

A bit of sleuthing in Terminal helped find the mystery location. The OS 9 software is in a hidden directory called .images on the first disc. Inside there are several files including OS9General.dmg. I was able to mount (open) this disk image to the desktop via the following Terminal command:

open /Volumes/Restore CD/.images/OS9General.dmg

That takes a few minutes, then mounts a volume called OS 9 Content onto the desktop. Inside here are our old friends Applications (Mac OS 9) and System Folder, just as we know and love.

To test this worked before sending to my client, I copied the two folders to an external FireWire drive (formatted with OS 9 drivers), then connected this to my MDD running Tiger. The Startup Disk Preference Pane showed the external drive with Mac OS 9 as a valid boot choice. Restart, a few screen flickers later, and voila! Welcome to Mac OS 9.2 appears on the screen.

Mission accomplished. I now had a valid boot system for Mac OS 9 on an MDD, along with the disc image. My client was thrilled to hear the good news, and I sent him a copy on CD the next day.

The story continues: Mac OS 9 Isn’t Dead Yet…

Update June 2012:
Mac OS 9 for PowerMac G4 MDD has been made available for download via the Macintosh Garden.

1. Hi, downloaded your cds on macintosh garden, to install on my Gigabit Ethernet, it now detects an os9 system but when I try to boot to it, a floppy with a question mark appears and my hdd starts spinning, any idea?

2. Hi,
   I have my old G4 MDD dual 1.25 and I have OS9General.dmg
   i try to burn it with Disk Utility and Toast, but it is not a BOOTABLE CD.
   I can only copy all folder and document on my hard disk and it work.

   BUT I AM LOOKING FOR A BOOTABLE OS9 INSTALLER CD or DVD.

   thx a lot

3. does anyone have the powermac g4 original restore disk for the 1.25ghz MDD 2003?? the disc im looking for is a DVD, and its part number is z691-4409-a – it includes 10.2.6 mac os x + mac os 9.22 as well as AHT 2.02. someone i spoke to online has the disc but he claims hes never been able to successfully copy it. is this a known issue to anyone else?
   i have the 1.25ghz mdd 2003 model and would like to get its specific original disc to restore it to factory settings!

4. Hi Adam, how did you create the partition on the external firewire hard drive and use the Mac OS 9 HDD driver to boot off it, Did you run the disktools in Classic to create the external partition, or is just “Blessing” the hard drive enough to set it as the active partition to boot from? I also used OS9helper in classic to update a OS 9.04 system that I copied off my previous Beige G3 Mac to install OS 9.2.2 within classic and make it bootable on a 2002 G4 Quicksilver that I built from pieces that I bought on Ebay.

   Thank you for the help, and the article!

5. I have a G4 mirror. It had 1 hard drive. Another computer I had was running system 9.2.2 for my Scitex, and it died. I took the hard drive and put it into the 2nd drive spot and hooked it up in the g4 mirror. I can see everything on that drive and I can access all the files. When I go into the system preferences and go to the startup disk and select system 9 and restart, I get a ? folder. When I try to reinstall system 9.2.2 I get a message Quicktime is not compatible, please upgrade to QT 6.0.3. When I try to start Classic it says the same thing. I need to run system 9 to run my Scitex software, any ideas?

6. Adam,

   I found a G4 powermac (the one with oval bay doors – quick silver model I think?) in the dumpster. Anyhow, I put a spare blank hard drive in it and it booted right up. It gives me the “wheres the os” ?/finder icon in the middle of the gray screen. Unfortunately I don’t have a FW drive or any clones of previous ppc 9 installs from back in the day.

   * I want to install OS9 classic on it but how does one open up the cd tray to put the cd in?
   * I do have some backups of my white intel iMac and my 08 intel MBP. If I switch them to a FW drive, will they work even though they are for intel machines?

   I’m hoping I just stick my OS9.2.1 disc into the g4 PM, and it should install 123 like my old bondi blue g3. Any other tips? Thanks for your help!

7. Hi Adam

   Thanks for your site – lovely. I had a collection of old Macs starting with a couple SE’s, moving up through 10 Classics, Colour Classics, several pizza boxes (LC, LCII, 430,etc),630, 4400, 6 Grey G3’s and 4 G4 towers as well as a couple of ancient laptops, an Atari STE and 2 BBC micros. Most of these I gave away to an IT technician friend who was starting a computer museum in his garage. I still have over a dozen original install/software discs for OS 9 and OSX for PPC, iMac, iBook, etc and wondered if they were worth keeping/passing on. They range from the old orange disks up to 2005 Mac Pro disks.

8. I have the MDD that is duel 1GHz can I replace the CPU’s with The 1.25GHz Chipset and Have it work? without any additional tinkering?

9. Adam,
   I wondered if you could help me with a trouble-shooting question.
   I recently had the “power supply” replaced on a G4 Tower (running OS 9.2) and computer boots, no problem. However, ever since, the computer seemingly refuses to accept any file transfer from any external device (whether a folder of pictures, other docs).
   A typical scroll bar appears indicating how many items new to be copied, but the scroll bar sits still, instead of moving, and in effect, stays still with no other action. I checked extensions, etc. for anything appearing out of sorts – but could not find a sourse of the problem.
   (PS – I use the G4 as a back-up server (to another G4) for a medical office software; the software will open – no problem – from any recent back-up off the main server; but as I said, I cannot copy the folder permanently onto the device, as I had long done in the past). Any thoughts would be sincerely appreciated, Thank you

10. I made a bootable USB stick with Mac OS 9.2.2, I can boot on it and install Mac OS 9.2.2 on my G3 : http://www.numopen.fr/Creer_une_cle_USB_Mac_OS_9_et_installer_Mac_OS_9
