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.

Resposta para "Charger cuts off laptop"The iView Megatron is one of those no name laptops, so finding parts will be hard to find for this if it’s a hardware issue. What brand of charger did you get, and did you check the polarity and voltage against the original? Center negative is rare these days, but you sometimes still see it despite the majority of laptops being center positive. Usually if it’s 1-2V off on a quality system, it can usually be safely suppressed by preventing power to run past standby or designed to not damage the computer, or they make it hard to use the incorrect one. A lot of these “entry level school laptops” aren’t designed with as much tolerance against this then say, Dell or Lenovo builds in. If the tip voltage is off by more than 1-2V, then you probably fried the motherboard. If that isn’t it, these things have a tendency to randomly die for no reason and it may not be your fault. Depending on the warranty status, they usually aren’t worth repairing if it’s out of warranty or iView is strict about warranty validation...
Resposta para "Switch out of S mode in BULK (100+ computers)"I’m not familiar with S Mode because I don’t mess with low end machines that seem to come with this BS, but would it be possible to erase the primary partition (keep the recovery!) and bury S Mode that way? After all, it’s a software switch which should in theory be easily removed with vanilla Windows 10. Of course clone the tester machine first just in case, but it’s an idea.
Resposta para "I spilled acetone (nail polish remover) on a laptop screen."Of course in this case, what you would want to do is base your response on your age, experience and how well you trust your parents to take it. I chose to take the repairs on myself (no permission) since I did not trust the response from one person specifically after a incident they used to have a power trip as an authority show. In most cases I was dealing with something that’s mine (in which case, I always settled it with take a hike) or something that’s OOW, but the parts would interchange with relative ease. I sustained it by holding onto BER devices and ones I was given that that were impractical to repair so if I needed a part I hopefully had it. I’m firmly in the “beg for forgiveness” camp if the circumstances match. Part of how I handle answers today is based on that principle if I can tell the OP can potentially handle it. If you can handle it, we need to know what the model number of the device is to get an idea how much the parts you really need will cost - for example if the LCD bezel is mostly...
Resposta para "PCI LAN: Realtek PXE B09 D00"Check if you see a hard drive present in the BIOS - LAN boot (which is what this Realek PXE message you’re seeing is) is a potential red flag of a dead drive, or a corrupted operating system. If you see it, you’re going to want to run something like Hiren’s Boot CD (Must disable Secure Boot if XX40 or newer- XX30 MIGHT need to be disabled if updated to enable Secure Boot) to make sure it works. You can run something that will do SMART testing and that should be sufficient to confirm if it’s a problem with the software or drive. If the drive has detection issues, do not mess with it if you need her laptop to work - replace it.
Resposta para "Replace Catalytic converter and P0420 still there"These newer cars are super sensitive about the performance of the cats, and O2 sensors. Did you use OEM Toyota cats and sensors, or aftermarket ones? If you didn’t use the Toyota OEM parts, then it’s usually due to the replacements not playing nice with the car. You really need OEM sensors and cats on the newer cars, sadly. It was fine 10+ years ago when the computers weren’t as touchy, but not anymore. You can put aftermakets on 90’s-early 2000’s cars no problem* because the ECU isn’t as sesitive to the expected range being off. *Or if you’re in a no inspection state, it will have a permanent P0420, especially when the car is 10+ years old and the cats are expensive :P. This is new enough it might be touchy about it, but possibly old enough to be outside of the snowflake sensitivity range. Being a Lexus, it may be more sensitive about it then the Toyota tune, just based on the fact it’s a Lexus.
Resposta para "My laptop is like died"First thing I would do on a “no boot” with fan issues is check the RAM - see if there’s an issue with how it’s seated, or potentially a bad module or two. If you have 2 modules, take 1 out at a time and see if you can get it to boot - if so, that module is bad. At that point, your best option would be to buy a matched set of RAM and replace both of the original modules to avoid any future compatibility issues, if you’ve confirmed there are no other issues. Follow this guide to access the RAM. If the issue persists, try and boot the computer without the hard drive. Some of these consumer machines (including Dell) are temperamental about booting with a failing/failed HD installed. Refer to this guide to remove the hard drive. I’ve never had an issue with the business Dells booting with degraded drives, but they tend to make the BIOSes more resilient to bad hard drives/RAM on the business computers, and least to the point it can push an alert and then beyond that it's still anyone's guess. It’s not unheard...
Resposta para "Charging Port Not Responsive At Times. Time is of essence. Please help"On this model, the power jack is modular but the display assembly will need to be removed to gain access. If you look at the battery replacement guide I do not see the jack being soldered to the board on this model. You can usually tell if you know what to look for. However, once the display is off the rest is relatively painless. The iFixit guide can be found here, but HP also has a diassembly video here. The HP Spare# (PartSurfer) is 801513-001 and they’re easy to find on eBay.
Resposta para "How do I open and permanently disable the camera?"In terms of physical, there is no good approach on the Macs since the newer ones are integrated in such a way you trash the assembly - the older ones are a glue and heat PITA. I wouldn't recommend tamper evident tape on the display directly either since it may damage the AG coating. Your best bet in this case is a thin webcam cover (NOT CHEAP TO REPLACE CRACKED DIPLAYS!!!) and tamper evident tape, or a fully SW configured block. Your needs may be better served with a used PC, like an older business notebook. On many of these, the cam can be left installed with a BIOS block (disabled in BIOS and doesn’t show in Windows) or you can physically disconnect it since most PCs are more friendly to such a thing. It’s the nightmares like my FHD Touch E7440 you need to watch for - it’s built in such a way I can’t take it apart without ruining a $120+ USED assembly easily. If you do not want to deal with it being present at all, you can sometimes choose lower spec models like my E6440 pre-display assembly swap...
Resposta para "Why is my laptop beeping nonstop?"DID YOU INSTALL PC3L (DDR3L) RAM? Haswell and Broadwell both require 1.35V RAM and cannot officially accept 1.5V RAM, as it can damage the memory controller (integrated into the CPU). Dell specifically blocks DDR3L machines from continuing POST VERY EARLY if 1.5V RAM is installed for this exact reason. In addition to that, some of the DDR3L required Dells are picky about mixed RAM and only like it one way, or not at all with that mixed pair. If you purchased the wrong type (PC3=1.5V/PC3L=1.35V), then the motherboard is shutting down as a protection measure - this happens before anything else for a reason. If it is PC3L, there may be a board or CMOS RAM issue. Pull the CMOS battery and see if it works; if not, try another set of RAM. If neither of those fix it, bad board. Refer to this page for more information.
Resposta para "chager tip broken off in machine how do I remove?"I’ve done this before on tablets before, but it is a bit touchy. If you have enough jack left, you can often use something like a safety pin and get it out, but you need to have enough jack left to “bite” the damaged part. This is usually a lot easier on laptops since you don’t have jacks that barely exist like a tablet, for example. Of course if you had a spare jack this wouldn’t be worth the hassle, but most people do not have common parts as spares like that around.
