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 who know what they are doing).
- TOC inclusion (Note: If removed for editing, add it back. This is fine if you need to remove it for the project term).
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.

Resposta para "I can't install macOS on my MacBook Pro system."Did you use the old SATA cable or replace it? I was told by @danj that some 2012’s use the 2011 cable and it sounds like you have the old cable. This was brought to my attention when I recommended the ‘11/’12 systems as a direct replacement for a SATA II capped MBP. Change the cable and see what happens; it will almost certainly work. The guide to change the cable can be found here, and the part can be found here. If you do not buy it here, you want the 821-2480-A cable; anything else cannot be used with modern drives.
Resposta para "What GHz to pick."You’re between a massive rock and a hard place on this one, since you own a 2010 :-(. These do not support SATA III (added in 2011) and NONE of the current production drives support it anymore (outside of Seagate, but you need to check the datasheet). As such, you need to find an older NOS drive with autosense from WD or HGST if you do not want to use a Seagate drive. This was put to bed for good on the 2011 which shipped with a SATA II drive, but supports SATA III but need the EFI 1.6 firmware to utilize it. If you get a good deal on a used 2011, the edu machine (EMC 2496) cannot accept a 3.5” hard drive and 2.5” SSD and may still retain the original limitation. The problem you run into now is if it fails, your refurbished replacement will probably be one of those modern drives without autosense so you can’t reliably RMA the drive with your system. You’re not in a great position at all. In addition to having to hunt down an out of production drive, you will also need an external sensor since Apple relied on ...
Resposta para "Can I add more memory to my HP Stream 11-r010nr notebook?"The SSD is soldered as it is eMMC. The RAM is also soldered and most of these only include 2GB of RAM. The problem with these is they’re 8.1 with Bing systems and they have special requirements in terms of specs that Microsoft expects to get the discounted licence. They need to have 32GB or less for storage (type doesn’t matter, but most use eMMC) and less then 4GB of RAM (most use 2GB to be safe). You will need a laptop with an actual upgrade path if you want to be able to upgrade anything.
Resposta para "Part of my keyboard backlight isn' t working?"I would be more concerned about killing your keyboard at a physical level over killing half the backlight. The backlight isn’t essential and you can live without it, but if the keyboard dies you’ll need a palmrest (keyboard is riveted in on this model) to fix it. See how your keyboard lasts for at least the month from when you did it. If it continues to work, live with the damage and consider yourself lucky. If it gets worse, you need a keyboard or palmrest. The stuff they put in nail primer isn’t much better then acetone in the amount of raw damage done.
Resposta para "What is easier to replace? The expansion port or the motherboard?"The issue with replacing the port is it’s mounted with SMD soldering so you can’t easily replace it. Unless you have a donor secondary board and really good soldering skills, you will mess up the connector if you even try removing it. That said, it’s rare for the connector to fail in general (unless you spilled Mountain Dew on the port). Try doing what @mayer suggested and look for burned resistors and capacitors. Unlike the connector, it’s practical to replace SMD parts on that level. It also wouldn’t hurt to protect the connector with kapton tape to err on the side of caution.
Resposta para "TI-30XS calculator repair in the USA"The screen is installed with hot bar soldering, so there’s no nondestructive way to replace it. You can replace it on SOME color graphing calculators, but any B&W model probably uses a hotbar. It’s almost certainly a limitation based on what is available with how common it is. I’m sure you could use a ZIF daughterboard and hotbar the display onto a subassaembly, but that’s not something the manufacturs will likely ever do. Not even good ones like the TI-84 Plus are modular but the CE is.
Resposta para "Laptop not booting up after about a week"Is the charger you got a knockoff? A lot of those things fail for no good reason and in some cases, they take out the motherboard because just dying on it’s own isn’t good enough for many of them. Been there multiple times when I get the notebooks pre damaged by these things or they were unwillingly forced on me by people who don't know better. If you got an aftermarket, stop using it NOW before it makes the problem worse. Find a genuine one (even if it’s used) and try to see if that solves the issue. If it still doesn’t boot, then you got a knockoff that wanted to kill a motherboard for no reason. You’re gonna need a board repair on this because it uses eMMC.
Resposta para "Updating from MacOS 10.7.5 on early 2011 MacBook Pro"High Sierra is the most modern version I’ve been able to tolerate right now. The problem with Mojave is APFS isn’t optional (even on a spinning drive) so you end up using a filesystem that’s not designed for the drive it’s being forced on. If you still find a way to opt out, Apple won’t provide system updates. You either become an APFS user against your will or you won’t get updates. Stick to High Sierra for the time being. It’s not much less feature rich then Mojave anyway, so you aren’t losing much. I got my installer from the dosdude1 patcher. Mojave sits on my drive uninstalled since I grabbed it thinking I may do it sooner then I thought I would initially. I don’t think so - at least until Apple realizes that APFS is not for spinning drives and these should default to MacOS Extended (Journaled) AND provide a easy APFS opt-out for those of us who do not want it.
Resposta para "Will the logic board from a 13' 2012 MacBook work in an early 2011"From what research on compatibility I did, it looks like it will work, but you probably also want the newer WiFi card to get BT 4.0 out of the system. There isn’t anything specific on chassis catches, so you may want to check the board layout yourself against a 2012 board to confirm all of the holes line up 100%. It looks like the card iFixit sells is the BT4 one for both machines. You will also need to replace the heatsink as the 2011 one won’t carry over to the 2012 board. Build this into your estimate at a averaged price since it may not be as cheap as you want it to be. When I got mine (Late ‘11 with livable cosmetic issues at a discount), I was told that there is no real performance gains with the 2012 i5, so you probably want an i7 board to make the bump meaningful. Without that, the only expectation I would hold if you do this is to only benefit from native Mojave and Catalina support without patching the installer. In addition to that, I looked at the boards for the 2012 and 2011 and the holes match u...
Resposta para "Is my Battery OK?"Is it one of the external 3 cell 18650 HP’s? Even when they were new, they’re known for bad battery life on anything other then a Celeron model from Walmart. This is one of the few laptops left you need a 2nd battery in your bag to not need to keep the charger on you. The problem with these is the battery is too small to be long enduring on systems with good hardware (i5/i7 or A8/10 APU). As soon as you drop to 80% capacity, the runtime goes out the window as well. The p263nr is one of the worst ones with this battery since you’re combining a low capacity battery with an A10 APU. On top of a high end APU, you’re putting that battery onto an AMD notebook, which is historically known to be more power hungry then Intel’s high end chips. Since the battery is still new, you have time to calibrate it and get a realistic metric of what to reliably expect for 1-3 years. I’ve detailed the process here. A lot of the information applies to older laptops that have seen some use, so some warnings may not apply to you.
