Students: Read this before claiming any of my pages.
If you are part of a student group and claim one of my Device pages or Wikis, please respect these guidelines:
- Only change content that needs to be revised. Leave working content alone.
- If the original content is mostly usable, it's best to do a revision with the original content and formatting preserved as much as possible.
- If any information is removed without replacement, verify it is inaccurate if known by others. If there is not enough time to verify it, please understand I did so personally before including it.
- If you find any content you can't verify but think it needs work (Ex: Information on how to use a certain game controller on PC), revise it in its current form.
- If such content is included, only replace the parts that need replacement - do not remove it or change everything. I've personally tested it and know it to work.
- Do not change the following:
- Non-patrol reputation (This is set high enough to prevent problems for me and established users).
If these guidelines are respected, I do not have a problem with student edits. I know how I handle it is more unconventional then other pages since I will centralize common problems (and their workarounds if I know what to do) to make the information easier to find.
Regarding major changes beyond normal editing: If you are considering a major change, it's best to err on the side of caution and use the existing formatting and replace that section. In most cases, the content is (generally) laid out in such a way that the only requirements are a rewrite on the section that is being changed. In most cases, there is no need to completely rework how I wrote the original content.

"Apple Display A1267 AC Plug Must be Repeatedly Plugged in to Power Up"に関する回答That’s usually a sign of bad caps on the power supply. You need to recap the power supply or replace it with a new one. There is no iFixit guide for this one, but you need to remove the glass, LCD and then unscrew the power supply for repair or replacement. For this one, you need a T10 Torx driver. In order to release the power supply, you need to disconnect two LED driver connectors and a primary power connector at the top of the power supply. The part numbers are: PA-2201-02A/661-4821.
"HP Pavilion 15-p Hard Drive Replacement"に関する回答The days of a raw PCB swap died with the mid 2000’s Maxtor DiamondCrash drives :-(. You need to transfer the ROM 100% of the time, since the drive parameters are stored on that chip, which is why you can’t just PCB swap. The other problem is you need an exact match drive with the right PCB and headstack preamp, since a lot of drives use different PCBs and headstack preamps depending on what is available that day. Even being 1 day off can mean it has a different PCB and preamp if the one in yours was not available that day. In short, don't try unless you are capable of finishing because any attempt hurts your chances and one mistake could be fatal. In short, you need to take it to a professional who does data recovery. You need a matching drive, the right experience and a clean working area.
"My laptop spec say maximum RAM is 16. Can I install 64?"に関する回答The RAM is soldered. This machine is too thin for a SODIMM slot.
"Need to order a replacement hard drive for HP Envy 27"に関する回答This just uses a normal 3.5” drive in both the 2/3TB configurations, so anything will fit in place of the original drive. Refer to this guide to change the drive out. The drive can be found here. If you want to install 2 drives and install your OS on an SSD, you can do that too but you’ll need to drop the optical drive since this lacks any “hidden” SATA ports that went unused, even if a special cable is required. You will need to install the SSD into one of these, and install the 3.5” drive normally. You’ll need to transfer the OEM faceplate over unless the generic one is in use - which sometimes happens, but usually not with an HP.
"Dell E7240 won't turn on"に関する回答Why didn’t you try the battery and took the nuclear option first? It’s often caused by a battery issue - on my E6540, my machine didn’t boot the first time and I either had to wait or press the power button twice to get a boot. When I ran it without the battery, that completely resolved the issue. The battery is more notorious for creating boot problems. In your case, the board was not likely to fix it and it was an expensive gamble. When it comes to the E7250, I see a lot of those with bad board like symptoms sold for parts. One or two isn’t concerning, but when you see them in large numbers there’s a systemic hardware issue. The Intel HD/Iris Latitudes are bulletproof - it’s the ones with a GPU that are more known to have hardware flaws like dying GPUs - the E7240 is too small to even have room to introduce that failure point. In general, a whole new board is about as much as a No HD machine you can transfer the ownership on and swap drives over, so that repair is typically not economically viable unless...
"Inspiron 5680 Desktop CPU Fan running at full speed at startup"に関する回答It’s normal for it to happen within the first few seconds on the Dell desktops - most people don’t notice because they don’t know it happens. If it stays like that for more then 5-10 seconds, it’s usually a RAM or power supply issue. The newer machines aren’t as aggressive as the older ones, but it still happens - likely so the machines can catch a fan issue and throw a POST error if something is wrong. The cheap common fault I’ve seen is fan swaps where someone uses a fan with false PWM, since the machine is somewhat specific about what kind of PWM data it expects. When it isn’t providing RPM data, the fans assume there’s an issue and run them at 100% speed all the time, along with throwing a BIOS warning up at boot time. If you see a boot error, start with the fan in question with these machines. CPU is 4-pin and rear fan is 3-pin. The first thing I usually do is inspect the power supply and if I see anything wrong, replace it and that usually solves the issue. You have a huge issue - 2 different power...
"Xbox 360 dvd/cd drive issues"に関する回答Usually when one of these drives stick, it’s due to a bad optical drive belt or worn out motor - as long as it’s reading discs, this is usually where the problem lies. The cheap fix is to replace the DVD drive belt, which usually fixes the problem. You can find a new belt on eBay. If it still has issues, the motor is bad. While you can replace the motor, you need a identical 5V replacement which can be used in place of the factory one - depending on your skillset, this may be more then you want to deal with and should look into replacing the DVD drive. On the 360, you MUST match the drive brands unlike the original or you will be console banned - and unable to read discs. As we do not know which one you have, you’re on your own - some of them are easier to get then others.
"Replacing emmc 32Gb with 128Gb? compatibility? socket?"に関する回答Yeah it's soldered in these eMMC lemons - there's no way to upgrade it unless you have a machine with SATA provisions like some of them have, but generally eMMC is a warning both your RAM AND SSD are soldered. It gets worse when it's older because now I need to keep a mental master list of known possible eMMC devices and inspect further or buy a specific configuration to avoid it. What a mess. For the 100% eMMC group, a do not buy master list.
"Top backlight doesn't turn on"に関する回答The first thing I would do on one of these is try the inverter and try my luck - you may get lucky, but as @oldturkey03 said many of these are at a point where the CCFL tubes are worn out and burned out due to high resistance after having thousands of hours put on them. The issue with these displays today is many of them are 10+ years old, and they’re beginning to show their age by having early failure warnings or burning out entirely, so I would do so with the full understanding it may be due to the screen. If it’s due to a bad screen, I would try the LED conversion - finding good compatible CCFL tubes is nearly impossible today, and you need to do all of them as a set since they need to have similar resistance or it will accelerate the wear on the rest of them.
"How to clean the dust inside of lens"に関する回答Dust rarely affects photos - if it does, it’s minor. In addition, you’re risking the entire camera over a little bit of dust. You’re better off living with scratches and internal dust, rather then trying to fix it and risk ruining the lens and needing to replace the lens - or potentially the camera. With dust it doesn't affect resale as it's a common non-issue, but scratches that affect little to none of the final photo mean you can get a good deal on a nice lens or camera if you're able to test it and make sure it's not in a high impact area.
