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.

"HP diagnostics give Replace Battery error for new battery"에 답변Your notebook supports HP UEFI diagnostics -- use that, not Support Assistant. I have found Support Assistant is largely useless at giving failure reasons that make sense. Follow the instructions here to install: HP PC Hardware Diagnostics Click on Diagnose PC hardware issues outside of the operating system. You will be able to write it to the hard drive and boot into the UEFI version, and not the firmware integrated version. This is why I STRONGLY ADVISE against Support Assistant, especially batteries: If you see Fuse Blown (42) or a similar code, with persistent issues like yours the battery is shot.
"Is there a CMOS battery?"에 답변These Acer "Cloudbooks" use a capacitor backed CMOS RAM, with a reference BIOS setting stored in NVRAM. If the machine has problems with saving BIOS settings, it is due to a bad primary battery, as it is held with a supercapacitor on these. I do not see a CMOS battery on the motherboard on this laptop.
"PC monitor image flashes once on startup, then stays black."에 답변In most cases, this is caused by bad capacitors on the power supply, or the driver board. First thing I would check is the external power supply; reference your original part number for this. I would contact LG first to see if you can buy one directly but if they will not sell it to you check on a site which sells LG parts. However, if it's something like a Delta unit you can probably just buy it anywhere. If that doesn't work, check the capacitors for wear on the LCD controller board; that is the second common cause for this issue. If neither work, it is either a bad LED strip, or a bad LCD. If the LCD is damaged, the cost of repair vs. replacement is rarely (if ever) worth pursuing.
"The taped or glued zipper seam on my board shorts has separated."에 답변What I have used on fabric in a pinch is Beacon Fabri-Tac. You need to clamp down the fabric and may need to add something like tissue paper if it's likely to leak inside and ruin the fabric. You can use anything with weight as a clamp. I have used a damaged EliteDesk 800 G4 DM chassis where it is just a damaged chassis and dead motherboard before, and it works. Once it sits for a few hours and you let it dry for 24 hours before use, it's probably stronger than the original material and can be washed. You need to be a little careful with how much you use, as it can leak. A few drops will do in many cases, but for a high wear item you may want a line of it.
"How can I add another account on my chromebook when my school blocked?"에 답변My chromebook has an admin on it, how do I remove it? See here. This topic has been done to death and back. The way the management works on Chromebooks means the admin needs to remove the restriction (spoiler: THEY WON'T). I can wipe a Windows computer in seconds with management with a NVMe/ATA Secure Erase in seconds, reinstall and its gone, which is why any smart sysadmin ties it with tools like Absolute Computrace which has BIOS persistence. This "wipe it and run" approach doesn't work on Chromebooks since the S/N is tied to the management console, not the Windows install. This (and cost) is why schools largely issue Chromebooks to students now. The "erase and reinstall" approach makes bypassing it inherently useless for network mischief, but it makes it easy to wipe it out for secondhand buyers when someone left a managed copy of Windows on the machine. With a Chromebook, I either need to contact the admin, or strip it for parts. Even if the machine is not tied to a MS AD account for management, you...
"Why is my battery not charging"에 답변These laptops are super old at this point. At this point, any of the original Dell batteries still in service are usually tired -- even the ones that almost made it to 10 years are degrading rapidly, even if they still run 1-2 hours 8-9 years later. Yes, I've run them for 6-7 years before, and kept original packs from 2013/14 in use until the degradation was too extreme. The first thing to consider here is to buy a new battery, but keep in mind that the cost of the OEM Dell is no longer worth it -- these laptops are so old the battery it costs as much as some of these computers in good condition with the specs that people want! This is why people include the tired battery, but do not guarantee the lifespan -- even some R2 resellers will include it so the new owner can eek out a bit more life from it. The problem is people expect the batteries to last, but they're just too old - use it until it's no longer in good shape or is not consistent about the ePSA health reporting and scrap it with these... Some...
"unable to write to the last block of device"에 답변Those use Seagate Rosewoods -- death of the drive is normal with those things :(. Unless you can replace the drive or warranty it, there's no fixing those Rosewoods.
"Laptop Rarely Boots when Power Button is Pressed?"에 답변That can either be a motherboard issue, dead CMOS battery or simply a corrupted CMOS RAM screwing with the bootup. Dells are also easy to corrupt, so I've scored cheap Dells I have no business owning for what I paid ($140 for a i5-8350U listed as an 8250U LG IPS without RAM/SSD) and all I needed to do was remove the CMOS battery and keep the primary disconnected until I seen it boot. No replacement was done. I wasn't expecting IPS for $150, much less LG IPS. That was a big deal with Samsung out of the TFT game (they were always my budget IPS favorite - losing them was kind of a bummer). All we have left is BOE and LG for TFT LCDs, since Samsung ships OLED laptop screens now, and QLED desktop monitors. Even if the laptop was hosed for $150, the LG IPS display paid for it because I could drop it into a BOE laptop, or a TN 768p which is otherwise well equipped. These are super easy too (but not as easy as my $150 Dell) -- you need to remove the main battery to get to the CMOS battery if you need to completely...
"Is it worth repairing"에 답변The audio chipset on this laptop is on the motherboard, so if it's confirmed to be a hardware issue it's usually not worth the cost sadly. It's not unusual for motherboards to be ~60-80% of the cost of a new laptop (or the same price as a like for like used replacement which isn't as easy with Toshiba to do). This issue also hits USFF desktops hard as well. Try reinstalling the driver and hope for the best, otherwise if that doesn't help reinstall Windows and pray it works. You can find the driver here: Support Home (dynabook.com). If all of this fails, it's the motherboard especially if you defaulted the BIOS settings out. As far as the trackpad goes, check the connections inside. However, it may be as simple as it was disabled in error, since a lot of laptops make that way easier than it should be. Tap on all four corners one at a time 2-3 times and see if that helps first.
"How much does this cost"에 답변After these machines get past 5 years, they're usually not a good idea to buy after that unless you cannot do something without that specific model, or you have a purpose for it. If you already own it, keeping it going is not unheard of. Personally, my general rule is 1-3 years (or last year's model purchased refurbished from the manufacturer) for those who can't self-maintain, then once it gets to be ~3-4 years old those can work for someone willing to self maintain the system as it isn’t too tired yet. 6+ for specific use cases or legacy applications. Like for example, if we relived my tech school memories of playing Halo CE and hosting class LAN parties with the help of a district employee at the time who was a student as well, I'd specify "Windows XP laptop" and leave the rest open to determination to the person taking part. However, I'd choose an E6400 (premium), or D630 (budget, no nVidia; those had issues with the GPUs) and an external mouse for my "play laptop" (back then, we did it PC to PC so...
