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 "I have something inside the screen"The front polarizer split from the screen. In this case, in order to fix it you need to either get a new screen (easy mode), or replace the polarizer (hard mode). Either way will work if you choose not to live with it.
Resposta para "Is the bios saved on the internal hard drive."This laptop has the BIOS stored on the EEPROM. Hard disk based BIOSes haven’t been a thing since some of the graphical BIOS Compaq laptops of the 80/90s and some early machines where there wasn’t any room on the flash ROM for it, or the space was limited. You also had the PS/2 approach which HAS an onboard BIOS, but the options were loaded as needed from a floppy as you added cards to the system, rather then present just in case.
Resposta para "How can I fix my wd "my book" and recover what's inside?"The problem with data recovery on these is the WD Ware USB bridge encrypts the drive, even *if* you didn’t enable the SW encryption - they all have encryption now, in hardware. It’s been like this since ~2010/11 with WD. In order to recover the data you will need to repair this PCB, or find another drive with the same PCB of the same model to swap it over which is known good, to even have a chance.
Resposta para "Is it worth upgrading these components?"When it comes to the CPU, it can help but the effort to performance gain ratio isn’t as great as you think. It’s not something I’d personally do, especially with the Mac being so old further limiting any gains. It’s often a completely different question in a system with easy access to the CPU, but you especially need to be at the top of your game to not screw the CPU swap up on an iMac. Remember, this isn’t like my custom desktop PC where if I got a good deal on a 9th gen i7 without the IGP, I can swap it in 10 minutes so the effort to performance gains are easier to justify, even if I’m coming from a 9400f and it isn’t much better and I need a Hyper 212 EVO as my Intel stock cooler will not cut it. This is because I’ve done it, my install risk is basically zero and if it doesn’t help much it wasn’t hard to swap out, so there’s less “upgrade regret”. The “professional rate” to get this done will total it out, so the CPU on an iMac is firmly a DIY job once it’s a few years old (unless you know someone who...
Resposta para "Are these still for sale? Or out dated?"The printer hasn’t been sold for years, to the point it is at least 21 years old. You can only get them used from places like Goodwill, or yard sales in a lot of cases. In addition, HP has pulled the drivers so you need to know the file location on the HP FTP server to get the drivers, or go 3rd party. Unless you have a technical reason to bother with this model, look elsewhere! As far as ink goes I think HP also stopped manufacturing it, but the reman cart manufacturers and Chinese cloners are still selling them. Even if HP still did, they ask too much anyway. Trust me - if you have a choice, you DO NOT WANT an old inkjet like this due to the ink costs, cart clogging and ink drying out. Find a proper workhorse mono laser (unless you actually need color) like the LJ 1200, or a 4000 series (like the 4050 - 11x17 model; Letter model is the 4000, 4150 - 11x17 model; 4050 for Letter or 4250). I picked a LJ 1200 off of the street from someone moving, and the actual page count on it at the time was 134,667 (669...
Resposta para "How can I secure this nut in place?"Usually when ABS plastic breaks like this, you can’t salvage the part and it breaks again. I’ve tried before and it never seems to fix, at least long term. In your case, you’re between a rock and a hard place. The keyboard is part of the palmrest so you need a upper case assembly, which increases the cost to repair the laptop, and it’s not practical to remove the keyboard and try and salvage the situation - you have to replace both, in practice (to add insult to injury on the Consumer machines, it doesn’t serve any benefit besides feeling spiteful). The other problem is being an HP Consumer machine, this happens more often then the other vendors (although, yes they all seem to have issues on the consumer side with this, and it’s a pretty common design flaw). This is not as bad on the Commercial notebooks - especially with the magnesium service panel which acts as part of the hinge mechanism to prevent this to some degree. This is the design in a Lat 7490*, by the way: Dell’s design ain’t perfect either,...
Resposta para "How to remove efi lock password?"Apple ties it in with the EFI firmware, so the RAM and NVRAM reset no longer work (hasn’t worked since 2011). With these you either need to patch the firmware (without screwing up the Intel ME region, otherwise you have a machine that runs at 800MHz permanently), replace the motherboard or go to Apple with POP. With the Apple Silicon Macs, I suspect it’ll be possible, but in practice impractical even if you know how to do it correctly, like on the Intel machines :-(. The way Apple designed the M Series SoC, Secure Boot and iBoot may mean you can’t do it anymore - whereas on the HP laptops (which yes, ARE just as difficult but if you’re careful is doable) you can dump the EEPROM, decrypt the password, and re-flash the laptop. Admittedly that’s been the case regardless of the vendor on the Windows side as well where other approaches are now required (outside of Purim, otherwise they enable it because most people favor security>modifiable BIOS) since HSW.
Resposta para "I'm looking to take the bottom off for cleaning"The trick with MSI is to unlatch the 3 sides before removing the cover - 100% not required, but get as many clips as you can. Once you unclip most of it, then you can stick something like a guitar pick by the jacks since you can use the leverage to sneak it in.
Resposta para "Questions about HP pavilion x360 (14-dw1052tu)"Usually HP uses Delta or Sunon, depending on what is available that day. My experience is the Delta fans tend to be better in the laptops than the Sunons, so try and find a Delta variant for your laptop. Many laptops use a semi custom fan, so you’ll need the exact HP P/N. Both are good fans, but I’ve found the Deltas are quieter for the same amount of air in many cases.
Resposta para "Touchpad: Tracks and registers Taps but not *Clicks*"Expanded battery - that’s how you know on these XPS laptops. Get the battery out ASAP, and replace it*. Refer to this guide to change it. Dell has had a lot more issues with expanded packs, especially the softcell XPS batteries! The reason it’s so bad is the lack of a shell increases the risk of chassis damage. With the old hard shell packs, the risk of damage was lower because you could use the shell as a buffer. Due to the risk of destroying more of the laptop then just dealing with it, just get the pack out unless you’re worried about breaking it - worry about Dell shaming you for it later - they tell you to do it anyway if you can, especially in your situation. *I would also check if it’s under warranty before doing so as well, but be careful it doesn’t kill the trackpad if you wait to remove it - this is a current model. If Dell asks and you DID remove it, you removed it to avoid damaging the laptop. STAND YOUR GROUND on battery removal, even if you need to argue with them over it since this is not a...
