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 "Please Help! There's Annoying Teal Blotches on Certain Colors"Looks like a screen issue, but before going and replacing the screen hook the Chromebook up to an external monitor and make sure it isn’t the same there. This laptop lacks internal HDMI, so you need an adapter. You can get a USB-C>DP, but DP is not exactly a consumer facing thing and it’s primarily reserved for professional displays - your best bet here is HDMI since it’s more common. If the screen is bad, a lot of these Chromebooks use the same parts but you also will run into a cost issue - parts often cost nearly as much as a good tested unit. As such, it’s usually not feasible to purchase major parts like the screens on their own. However, you can always buy one that has a leftover enterprise lock that the previous owner refuses to help with, and get it that way. Try to find a matched model Chromebook for this (or at the minimum, a nearly identical version of yours with the same resolution LCD), but if you can’t it looks like HP FINALLY abandoned LVDS on the newer MediaTek based units :-). This is...
Rispondi a "Lat E7440 intermittent audio issues - any fix?"Went with the nuclear option. Tired of fighting the previous install. Yes this weird graphical issue is not unusual for me and it also happens on my 840 G3 - this is not unique to Dell. It has no effect on the final installation so I can't justify finding why.
Rispondi a "How to fix loose hinges on a Latitude E6410"This era of Dell is notorious for bad hinges - the piece that screws to the back lid likes to split from the shaft with time, and it requires new hinges - nothing else works. Take a bad set out and pull the part that goes to the LCD and lid off - plain as day when it’s worn since it just pulls off. In most cases you get hinges that feel like they need a dose of Viagra but yes, they can (and do) completely fail like yours did. While it can be repaired, the snag with these machines is this will be a thing you need to keep repairing until you replace the entire laptop with a less troublesome model due to how severely affected these are (unless you know how to spot a good set by feel)! Sellers actually disclose this issue (AND sell the machine for parts) due to how likely it is to completely fail like yours! It's not superficial!!! That said, try to tighten the screws on the port caps, and the D screw under the cap and pray - you can sometimes repair the laptop that way (or at least delay the inevitable, since...
Rispondi a "I have a ZTE N817 cellphone how do I remove the sim card please"It’s under the battery cover, which is a common placement point on these lifeline provider phones. Looks to be a Micro SIM as well, since they also tend to be one generation behind phones everyone else buys. To remove it, you use your finger and pull it out. If the SIM card is being replaced due to age (and will be deactivated), you can always use a tool like tweezers once you have a solid grip on the SIM but this may destroy your card beyond repair.
Rispondi a "How can I replace the Intel Celeron with an Intel Xeon?"CPU is soldered on this, along with all of the Chromebooks. In addition to that, you need a Xeon ready mobile chipset which is typically only found in the likes of the HP Zbook/Dell Precision/ThinkPad P Series, and it’s optional with all 3 vendors across the board. In addition to being an option, the upgrade cost is not cheap CPU upgrades due to the cost of the chipset+CPU, and usually a whole different motherboard. You only see a subset of the used population with Xeon parts due to the cost for a reason - most people look at the price, get sticker shock and realize it’s a want. And they fetch a premium :(. I’d love to own a Dreamcolor Zbook 17 with the Xeon, but they’re already expensive with the i7 used. They’re even worse with a Xeon! It already hikes a NEW Zbook 17 into hollywood/bulk college fund prices and they fetch accordingly on the used market due to how many people take HP/Dell/Lenovo up on it. You can also load them with a ton of RAM - some max at 128GB, with others going to 256GB with 4 DIMM...
Rispondi a "Best arrangement of stock and 3rd party RAM?"When it comes to RAM, best to match it all with a matched module set - ESPECIALLY MACS. Apple is particular about this to the point one bit it doesn’t like=POST error. You can’t mix and match with Apple… At all, generally. Buy a matched 3rd party RAM set from a company like Crucial (MUST be Mac memory to be sure, unless you’re a gambling man), keep your factory RAM for warranty purposes or buy memory from Apple - again, note which ones were added by you and remove them for warranty purposes but keep the stock RAM installed.
Rispondi a "How to remove wrinkles from pouch batteries"Small wrinkles are fine as there’s usually no cell damage - the issue is this is a bit too far to consider “safe”. Dump it and get a new one.
Rispondi a "monitor for security cameras dvr"The issue with this monitor is it only likes a handful of resolutions or it goes “out of range”, and is limited to 1660x900, so the resolution support plus obsolete resolution aren’t doing you any favors with this security DVR. Contact the company who makes it, and see if you can force it in the supported range:
Rispondi a "Can I retrofit Thunderbolt 3 in Precision 7520"Does the computer have the USB-C/TB3 hole on the board by chance? If not, you’ll also need a new upper chassis as well. I’m doing some research on this, and it looks like the option is a different motherboard so you’d need to change the **entire** motherboard most likely :(. Sad to say, if you bought this used in error you’re better off putting back on the market and making sure the next one supports TB3 - if bought new, live with it or sell it depending on how bad you want TB3. Even then, Dell seems to have a lot of USB-C/TB3 stability issues, so you may have avoided a problem here as weird as that seems. They seem to even have trouble with FIRMWARE UPDATES resolving the issue as well. Win10 21H1 doesn’t even help the issue, so it’s something with their USB-C/TB3 firmware. My HP EliteBook (840 G3) lacks TB3, but it’s USB-C port is stable so HP and Lenovo* do not seem to have any issues like Dell. Sad to say, Dell isn’t what they used to be between the plastic chassis, unstable TB3/USB-C firmware and cheap...
Rispondi a "Why does my laptop keep randomly turning off?"Try replacing the power adapter, and hope for the best - the HP “smart” 65W adapter these 15-X machines come with is so light I have a feeling they are cheaply built internally. Try and get an OEM 90W, or a 65W - I personally use the travel 65W on my HP laptop (840 G3) and I’m happy with it. The ab laptops can run on a 65W no issue due to the low specs if you want to save a few bucks. DO NOT buy another one of the original 65W “smart” adapters, even from the HP store (Spare# 714657-001). They are hot garbage! This is the one I use (paid $41): HP Travel Power Adapter (65W). Alternatively, look into the 90W version. I do not like the “smart” adapters due to how light they are, and their tendency to prefer power savings>power means they age badly and fail in weird ways. Unless the 65W is on sale at a very healthy price cut I do not recommend it as it is usually only $10-15 cheaper in most cases. It was ~$41 for the 65W vs. ~$65-69 for the 90W when I got mine. The 840 G3 can use the 45W as well which I know...
