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.

Ответ на "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. 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 anyone's guess. It’s not unheard of, so don’t...
Ответ на "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.
Ответ на "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...
Ответ на "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.
Ответ на "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.
Ответ на "How to fix the Epson L220 All red light blinking permanently?"If the paper and ink lights are blinking, that’s usually a waste ink (WIC) problem, especially if it’s persistent - what that means for you is the pad is saturated. Some are clearer about it in Epson Status Monitor then others, so it trips people up unless you know how terminal that error is. The 2010-present models tend to go belly up over waste ink within 3-4 years, without fail; I am not surprised. The days of seeing machines like the C88+/R200 series run for 10 years ended when Epson lost money on workhorse models. Sadly, it’s generally cheaper to dump the entire printer over WIC problems. The part and required SW tends to cost more then a new machine. Buy a B/W laser, especially if you do not need color.
Ответ на "Why are there green and purple lines and some parts are black and whit"If it’s isolated to the internal LCD, it’s usually a TAB failure and a new screen is required. If you do not see this on an external display, the issue is with the internal LCD. In the case of the Switch 3, it looks like you’re dealing with a touchscreen where the LCD is fused to the glass with LOCA glue. Sadly with these, the only good option is to scrap the assembly. It CAN be done while preserving the original, but I’m still playing with methods as I go when I get junk displays as I go. My first attempt was a success in the sense I broke no glass, but I broke internal components of the assembly. My second run is going better, but I broke the glass. As you can tell, you stand no chance as a DIYer if I’m having a hard time.
Ответ на "How to unblock sites on an HP Chromebook"It can’t be done. The way Google does it makes it impossible to the point even if you change the serial number, it will be managed again if you ever reset it. I’ve went deep into it (and had to prove myself), so I know what I’m doing. If there was a way I’d know. Google has the serial number flagged as managed on the cloud - it cannot be bypassed. It’s a iCloud lock, but for Chromebooks. My chromebook has an admin on it, how do I remove it?
Ответ на "Replacement battery nowhere in stock/untrustworthy companies"Are you looking at a genuine pack, or are you okay with a trustworthy aftermarket pack? I’m in this same boat with my cheap E7440 :(. I got a really good deal since I needed to do some repairs, but no battery. However, since the machine needed work (and the part is not cheap), I bought a donor with the part I needed and looked for one that came with a battery. It worked out for the screen but not the battery (possible expansion issues; known to happen on mistreated E7440 batteries). I’m able to find a genuine pack from PartsPeople, but they’re out of stock like everyone else. You’re probably going to have to wait until Covid stops shutting the schools down for parts availability to improve like everyone else. Parents are buying all of the batteries up right now.
Ответ на "Need to restore computer to like new again"The odds it still has it’s recovery partition are sadly extremely low. As such, your best bet is to borrow a computer from someone else, download the Media Creation Tool and make a USB boot drive. Once the OS is reloaded, then you can find the drivers from the Acer website.
