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.

Antwort auf „My TV has lost brightness to about 80% of the screen?”I would check if there’s a partial LED array failure, especially if the TCON board doesn’t help. I have seen it where you lose some of the array on one strip, but not the entire array before and it looks like a partial failure since you lose enough of them the entire array is dead or compromised. In most cases with multi array displays like this, you lose one but not the others and it’s half dead - which is what happened here. In your case, it looks like a partial failure where you have 2+ arrays, and one or more has completely failed. Partial array failures are unique in that you have a unusual failure like most of it works, but there are noticeable backlight performance issues like part of the display being dead while the rest works. Generally speaking when you see issues like that, it can be repaired with donor strips. The issue is replacing the panel costs more then the TV is worth most of the time, so there is really no economical way to change the screen; it’s usually only viable if you change the...
Antwort auf „Do I need a new I/O board or a new battery to fix my problem!”You need to recalibrate the battery and do an SMC reset in order to clear the error most of the time. Once the SMC reset is done, recal the battery. While this guide is focused around Windows machines, the same principle applies to Macs, but the difference is you won’t be able to fully drain your Mac like a PC. For this machine, use it until it goes to sleep and charge it back up to 100%.
Antwort auf „Unable to remove the screws of the back of the laptop.”Someone screwed the rear panel on from an angle from the factory if this is your first time opening it. Sadly, you usually lose the post as well if this is one of those aluminum skinned machines because it breaks when you try to get it out. However, you do sometimes get lucky. A lot of those thin laptops screw out from an angle on the sides, so this may be user induced if you had to do it from an angle :-(. What I’d do first is try something like a pair of screw extracting pliers first before going to more drastic measures. If this doesn’t work, you may need to cut the head of the screw off, remove the remains with pliers and relocate a screw that’s cosmetic, especially if this is near the hinges.
Antwort auf „The computer doesn't boot when the hard drive is plugged in- RESOLVED”Generally speaking, a hanging BIOS is typically due to a failed drive with a BIOS that doesn’t handle dead drives well, or it’s a legacy system which requires manual cylinder/head data to determine the type. Update: Since your system is from ~1996 with Socket 7, you are going to be dealing with a 28-bit LBA BIOS which is limited to 128GB - so essentially the largest drive you can install is 120GB. With many legacy systems like that, you have to know which “type” your drive is, especially if the AUTO detection does not work (it rarely ever does). The drive type must match the capacity you are installing, otherwise you run into detection issues OR drive write errors beyond the capacity of the drive - but in some cases, the systems just don’t boot. It hasn’t been printed on drives in years simply due to the fact that it’s not as necessary today. In order to find it, it is based on the Hard Disk Cylinders and Heads (Sectors are often calculated from those numbers). This data is normally put into the BIOS in...
Antwort auf „Are there ways to make it run cooler?”Have you ever repasted the CPU? The paste usually goes bad within 2-3 years, sometimes 4. Refer to this guide to remove the heatsink. In addition to cleaning the paste, clean up the dust in the fan and heatsink fins. After a few years, the fans tend to clog up with dust and run slower. It may also be due to a bad heatsink, especially if a ULV machine like this is running hot - these shouldn’t get too hot even with a 7500U. It may be normal for it to run hot, as many laptops tend to run on the warm side with some being worse then others. If that doesn’t help, there’s no way to replace the fans (even if you could, Lenovo PWM is temperamental if it even suspects a bad fan) so you’ll either have to live with it OR get a cooling pad.
Antwort auf „Can I repair my motherboard?”There’s not much you can break there without fatally damaging the motherboard. You can lose. small corner, but losing much more will ruin the board. We need photos of the actual board to judge if it's repairable or a total loss. Boards aren’t cheap in the US; $50-70 from a quick eBay search.
Antwort auf „PS4 Pro won’t power on, roach infested”Bag that thing and roach bomb it first!! You don’t need to take it apart for this part since the goal is to bomb as many as you can before exposing them and seeing how many survived - DO THIS IN A OPEN SPACE; NOT YOUR HOUSE/APARTMENT! After you roach bomb it, then you’ll need to take everything apart and clean each part individually. Make sure you take the DVD drive apart and clean that separately, along with the lasers. The problem with roaches and the PS4 DVD drive is they hide in there, and the lasers get dirty. You may need to replace the DVD drive. I once (stupidly) took in a roach infested monitor so I can warn you now it’s going to smell musty. What you NEED to do to get rid of the smell is use Greased Lightning Classic on the metal and plastics - it removes the smell so the roaches don’t go back to it. Do this now, or it’ll become infested again. After you clean the rest of it up, it’s probably a power supply issue so I’d start there. Roaches seem to love the PS4 power supply, so focus on that...
Antwort auf „What means Greasy yellow fluid in the valve cover air vacuum hose?”Check for a head gasket leak - these 2000-present Renault Nissans are notorious for blowing head gaskets. You can get a kit on Amazon. We don’t know which engine you have, but from what I understand the 90-99k mile range is when these start blowing head gaskets. You can find a head gasket kit here (all seals and bolts). To do every seal requires the engine to come out, so you may need to defer this to a mechanic - if Nissans weren’t so famously bad for it, you could probably just get away with doing the one for the valve body. Head gaskets can be a PITA on many engines - especially Nissan/Renault.
Antwort auf „Game shark and Pokemon silver”The problem with devices like the Game Shark is they do mess up save files beyond repair if you use conflicting codes - generally, once you damage the save there’s not much you can do but start over. Have a cheat save and a no cheat save next time :(. If the game doesn’t want to load, the save you did it on is so corrupt it cannot boot. Refer to this guide to open the cartridge, remove the battery and replace it. Run it without the battery to be sure the saves are gone. However, it may be possible to erase the saves by doing it before the game loads.
Antwort auf „6.92 out of 8gb usable”It sounds like it’s being used to run the integrated graphics. These have a Vega 8 GPU+integrated enabled configuration, which is in line with many of these gaming laptops - you don’t need a Vega GPU for Microsoft Word. Run a game or something that will use the GPU, like GTA V. If it’s all available then, you’re losing RAM to the onboard GPU taking memory from the primary system RAM. HP locks their BIOSes down pretty far, so you may not be able to reduce the excessive shared video memory *easily*. The HP BIOSes that replicate the business BIOS (with business features disabled) are locked down in terms of adjusting the VRAM, along with the AMI UEFI Reference BIOS. Unless there’s a hidden “advanced BIOS” like there was back in the Legacy BIOS days (which is hard to access), you cannot change it through the BIOS. Give this a shot, but bear in mind it may not work since these are UEFI based and not a Legacy BIOS - plus HP is using the keys for other functions now, so that makes it more obscure how.
