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.

Respuesta a "Dell XPS 15 9550 97wh Battery Compatibility?"In terms of the fit, I’ve got some information on this. On these Dell laptops that use the internal softcell battery, they tend to come from the factory “compromised” unless you only rely on a M.2 SSD because the bay design does not allow you to fit a 2.5” hard drive into the machine unless you also downgrade the battery. It was a big deal just a few years ago but IMO with how cheap M.2 SSDs are now it’s not as much of an issue - but if you want a cheap ass storage upgrade path don’t install one of these packs. Note about mSATA systems (Usually Haswell/Broadwell): if you have one of these and choose to eliminate the second drive you will need an mSATA SSD. If you have a 2.5” drive it's highly advised to keep it since mSATA is normal SATA with zero benefit other then size since even the TBW rating is compromised. I recommend keeping the compromise battery in these and not bothering with the slot on consumer hardware or only a WWAN card on business. If you want dual drives, you’re limited to 56Wh packs. The...
Respuesta a "Why is my fan so loud?"Gaming laptops tend to be loud by nature due to the higher TDP CPUs and high end GPUs - there is no way around it unless you split the load with dual fans. Acer does use dual fans, but they don’t dedicate one fan to the CPU and one for the GPU, so they run into the same issue as you do with one fan. What can sometimes be done to help the situation is to use a quality thermal paste like Artic MX-4, but if you just got the laptop brand new and nobody else has used it, it’s not something you should really do until the 3-4 year mark unless you have issues within the first 1-2 years with the laptop. The only time you mess with it right away (or after the return period) is if you bought the laptop used and do not know if it’s been done, and you want to be sure.
Respuesta a "The built-in webcam is not working Dell Inspiron 7537"The camera typically doesn’t require a special driver - it’s either a bad BIOS setting or a camera/display cable issue where everything works but the camera. Start with the camera module and if that doesn’t work, you’ll need to change the LCD cable. In this case, the camera module is less invasive of a swap then the LCD cable. If you don’t see the camera, you can check the BIOS and see if it’s enabled - if it is, then it’s typically a hardware issue with the camera itself rather then a Windows driver issue. You want to see if this setting is enabled in the BIOS correctly:
Respuesta a "My shift key is not working anymore ;-;"The rubber dome or keyboard matrix has failed, and you will need to replace the palmrest assembly, sad to say - the keyboard is not modular so that does increase the cost. The other problem is Chromebooks have expiration dates for auto updates. It tends to be ~5 years on older ones, and ~6.5-7 years for more recent platforms, so you need to check especially with used ones. This Chromebook “expired” in terms of updates on June 2019, so it has been 16+ months since it went to unsupported status. If it doesn’t bother you parts tend to be cheap for EOL Chromebooks because of ones people stripped for parts and “as-is” ones with an enterprise lock that wasn’t removed, so you can get creative with finding the part and have a good shot at it if you need to do that. That said, you may want to at least consider a newer model with a few years left if the repair cost is similar.
Respuesta a "How to remove ransom ware from laptop"The only good way with ransomware is to wipe the drive the OS is loaded, while preserving the recovery partition if it has one and isn’t damaged. If the system has a recovery partition from Dell*, then you can use that but you can also wipe it with the Media Creation Tool image. However, if it has a recovery partition do not delete it unless it was also damaged. *Dell switched to the Microsoft tools from their own on some late production Windows 10 systems, while others have the Dell tools even though they encourage you to use the Microsoft method. I BELIEVE systems shipping from ~August no longer include such a partition from the factory with Dell. The issue with Windows 10 systems that wasn’t a problem with 7/8 is most manufacturers no longer rely on a traditional recovery partition from the 7/8.x era, or ship reference installation media these days. With a business computer, the people buying them are capable of reinstalling Windows without a recovery partition or image them with a corporate image so...
Respuesta a "Can I play movies of my tv"Depends on how picky the content is about having HDCP - you will never get things like Netflix or Blu-Ray movies to work (honestly, you’d probably want a better projector anyway!) but anything that isn’t tied to content protection will be “fair game” on a projector like this. Keep in mind the image will not be the best since this is a toy projector like today’s LED ones with the 320x240-800x480 single LCD configuration (50-150 actual average lumens), so set your expectations accordingly.
Respuesta a "I know this is an old pc, what cpu’s are compatible with it?"The problem with CPU upgrades is not that it can’t be done if the CPU is socketed - the problem is time investment vs. performance gain unless you’re going from a low end entry level CPU to a solid midrange or high end one (Ex: Pentium B950>i5-2450M/Turion II P560>Phenom II N970). There are multiple problems I see on the value side: (1) For Intel systems, the gains are better but you have to be coming from something very low end like a B950 to a 2450M to make this project worthwhile ($15-20 for a used 2450M). You run into similar issues when you move up the i3 on the Intel side as you do with AMD (+864 points with the i3-2350M>i5-2450M). I would only do an i3>i5 swap if I had a compatible CPU and it cost me nothing personally with such close margins. Sub 1,000+ gains aren’t worth the effort required. (2) On the AMD side, the margins are low even when I assume the system shipped with a Turion II P560. You’d need to max this out with the N970 for it to be worthwhile with AMD boards - and you only gain +829...
Respuesta a "Is it possible to change the keyboard?"HP has spotwelded it onto their cheaper consumer laptops since 2013-15, so the answer is usually no unless you buy a business laptop that is known to be safe. The Stream and entry level Pavilions are usually the suspect ones in this regard. They even do it in their thinner business line laptops on some so you need to check, but haven’t fixed it in permanently on the Z series. However, HP has a few models on the consumer side which are known to be screwed in where it can be done, but it’s a painful repair since you need to tear the laptop down to the chassis, remove a LOT of screws and then do the same in reverse to reassemble the machine.
Respuesta a "Hello, my toshiba satellite laptop recently started not charging"In this case, I would remove the battery and run without it for the time being - not ideal, but it’s better then nothing. These kinds of issues are usually due to Windows power management misbehaving due to a worn out battery triggering the low battery display dimming. In other cases, one or more of the cells in the pack failed and the computer is trying to cope because the BMS didn’t blow a fuse or trigger a failure flag on and kill the pack. It sounds like the pack was on the way out for a while and you finished it off last night by charging it for the last time. What can sometimes happen is a tired battery that is no longer usable (but has no bad cells) will screw with the Windows power management if it’s really worn out. This can happen on machines with a BIOS that isn’t coded well enough to ignore bad packs at the firmware level if the BMS hasn’t thrown the failure bit, which shuts it down at the pack level. IF one of the cells is bad and the permanent failure bit in the BMS IC doesn’t trip, that can...
Respuesta a "There are vertical blue line on projector screen all time"Sony uses 3LCD, so that’s typically due to a bad LCD on the 3LCD prism in the projector - in this case, the blue LCD failed. Unless you can line up an individual blue LCD and adjust it so it’s properly calibrated, you usually need to replace the prism with a pre calibtaed assembly with all 3 LCDs attached. The issue is aligning it on 3LCD systems can be difficult. Depending on your experience level, you’re usually better off replacing the entire prism/light engine with a known good one that you do not need to mess with. The primary issue is you usually need to calibrate the other LCDs to be sure everything lines up. Every panel is slightly different and it's not easy. In most cases, the cost to repair the projectors when you run into issues with these 3LCD projectors is usually cost. Parts tend to cost significantly more then even used equivalent replacements - with many having fewer verified lamp hours as a bonus. You run into this same problem with cost on the DLP ones, so this isn’t a 3LCD specific...
