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.

Rispondi a "The Card Reader becomes "blocked" after receiving a small shock/hit"With devices like this, they tend to have tampering traps in them to kill it, as it is a PCI compliance requirement. Disconnecting the coin cell probably dumped the encryption keys. In this case, call support and deny opening it - just tell them it was suddenly blocked. It likely needs a hardware repair, so hopefully there were no tamper seals.
Rispondi a "How to replace battery"On many of the newer Dell laptops, you have to remove the bottom cover and usually 1-4 screws to release the battery. Once you do that, disconnect it and replace. Refer to this manual (online edition) to remove the battery.
Rispondi a "**DIMM Not installed** despite having RAM present"@jayeff Another update. I took this system replacement in a completely different direction then I was thinking I would. I primarily made this decision because I have 3 batteries for these (2 OEM/1 aftermarket) and the performance of the i7-4600U is similar to the i5-4300M, and I'm not going to need batteries for a little bit since my 6440 battery is a far cry from what it used to be even months ago and I need to replace it anyway - ePSA fail tired*. This originally ran Win8.1 Pro with a 128GB M.2 SSD in an adapter** since I bought it no RAM or HD. I wanted it to be as identical as possible, so I installed 10 and ditched Win8.1 Pro. Sadly, Win8 is showing it’s age with degraded SW/HW support. *I was able to coax it back to “fair” health, but once it fails ePSA it’s time to replace it. **Dell also did this with the SM841N mSATA SSD as well as a 5mm mSATA interposer on some, so I did something similar with a enclosure from eBay. Mine shipped with the WWAN slot populated with the 128GB SM841 SSD before it was...
Rispondi a "How to wipe out my school stuff and restart everything"This is not the first time this has come up, and I’ve covered it before. Back in school, I was able to grab printer IP addresses, bypass the web filter and make a deal with the admin department because they were tired of fighting me. See this answer for my expanded take on this: My chromebook has an admin on it, how do I remove it?. IT DOES NOT WORK. The Chromebook remote management is tied to the device serial number, so you need to replace the board or contact the company who put the management on to remove it since it will always be there otherwise without a new board. In addition to that, post “CR-48” Chromebooks are patched against the CLI serial number swap, so in order to change the serial number you need to know how to do board reworking, own a flash programmer and how to program in hex. In addition to that, some of them encrypt or protect it in such a way you can’t practically change it or it wipes the chip if you try.
Rispondi a "Has anyone got this lifeline phone from Qlink?"Usually with the free phones these lifeline providers give you for free tend to not be the best things you can get. You’re usually better off buying an old flagship (1-2 generations old) factory unlocked (or unlocking it yourself) and bringing your own to these services, when you can do it. It will probably be fine for basic usage, but do not expect it to perform like a higher end device. I haven’t ever owned a lifeline phone (even used), but their performance tends to be similar to SIM locked (subsidized) prepaid phones from the big 3 (AT&T/T-Mobile/Verizon).
Rispondi a "Battery or hard drive? Which do I swap first?"First off, don’t clone MacOS - it hasn’t worked reliably since Lion introduced recovery partitions on some of the newer Macs! You want to backup the Mac and restore it from a backup after clean installing the OS. Second, make sure you swap the HD cable in these - the original cables are often SATA II and they will not work right with SSDs due to that. It’s one of those issues I fix in these right away as soon as I have it open, so I know it’s been fixed due to how bad a failure can be. Before you install the new cable, the trick is to put electrical tape where the old cable lived before installing it. In terms of where to cover, refer to this photo of my old 2011 13” - I did the same in my 2012 13” when I swapped cables.
Rispondi a "Best practice for removing dirt/dust from fans?"What I do is I use canned air, and at least partially disassemble the computer to the point I have good fan access to get rid of the majority of the dust, just to make things easy for ones which aren’t too far in the dusty range disassembly is justified. However, if I don’t know if the machine has been maintained, or I got it used I am a bit more through. What I do on machines I know haven’t been maintained or cleaned in years is I will usually take the fan off of the heatsink assembly, when possible*. After I do that, I blow the fan out separately from the computer and then focus on just dealing with the dust bunnies in the heatsink fins. Depending on the age of the machine, I also repaste it. *The exception is machines like the AMD 8690M+HD 4600 E6440, which requires heatsink removal to get the fan out of the machine. For these, I usually just knock out most of the dust and do the real cleaning when I repaste these systems. The HD 4600 units with the easily serviced fan and heatsink are units I unscrew...
Rispondi a "Replacement battery not detected"Since you cleared out the CMOS RAM, it sounds like the BIOS doesn't like the pack. The iFixit batteries are aftermarket, and Dell BIOSes are touchy about accepting them. I got one for my E7440 from iFixit and when I enter the BIOS on the system (running A25, on purpose) it will complain by saying Not a Dell battery. This doesn’t surprise me one bit - Dell was affected by the Sony recall in 2005/6. The issue now is Sony made them hyper paranoid about 3rd party batteries :(. It works in ePSA or normal boot modes, but if I dare go into the BIOS it fails. More then likely your tired OEM works because it has the right information, but the 3rd party is different. Unless you find one where they cloned it and have good compatibility, you will often run into problems with Dell and 3rd party packs. For the internal packs, I recommend going OEM due to how particular Dell has designed the battery authentication to be, and the amount of issues the knockoffs tend to have. I can use 3rd party packs that do *enough* in my...
Rispondi a "Issue with machine not accepting new SSD"The issue you’re having on the 2012 is usually due to the SATA II HD cable issue in these, or flat out cable wear. The issue with these original cables is the wear tends to be invisible, so you never know it until you put an SSD in - which is why it’s better to change the cable yourself when you get the computer. You also need to protect it, because the aluminum milling wears out the cables as they move inside the chassis. The issue is so common when I got my 2012 13” I proactively replaced the cable so I knew it was done. Refer to this photo from my old 2011 (bad board and the LVDS cable fell apart when I took a look at it to see if I could fix it, so I replaced it): The Kapton tape is extra, so it’s optional. I did it at the time because I felt it was needed, but did not carry it to my 2012.
Rispondi a "Item number for ac power adapter replacement."For this laptop, I cannot find an adapter from HP on their website, so the OEM adapter may be “EOL” at this point. For this model, you may need to settle on a used OEM adapter. The HP Spare# is 239705-001. I’m not going to make any recommendations on where to buy it, but what I would do is take the Spare# and check sites like eBay for it specifically. You may need to supply your own power cord, but the brick shouldn’t be that expensive. They tend to go for $10-20 on eBay, new or used. They’re so cheap because of the sheer amount of dead units that came up over the years, while the adapters often held up longer then the computer itself. People usually find the adapter after realizing the computer died years ago, and sell it. Don’t spend a lot on this laptop - it’s a Vista era HP from 2007. It probably only still works because it’s not one of the nVidia units, which are basically all dead, or dying at this point.
