Re: What is it with Lite-ON Drives?
Some lite-on drives use a magnet in the tray mechanism to clamp the disc to the spindle. The tray motor loses stength over time and can't overcome the magnet's clamping force to eject the tray. I've found that replacing the tray motor in a stuck shut lite-on drive will usually resolve the issue of it not ejecting. I used to use tray motors from old CD-ROM drives I had in a parts pile to repair newer lite-on DVD burners, with decent success rates. Some of those older CD-ROM drives had very torquey little tray motors, though most of them eject the...

Re: question about installing a cap rated for a lower temp
On a motherboard, 6.3V 3300uF capacitors are almost definitely a very low ESR capacitor. 85 degree rated capacitors are almost definitely not low ESR. I wouldn't expect it to work for very long, if at all with that replacement.Leave a comment:

LTEC LTG specs?
Does anybody have a datasheet for Ltec LTG series? I'm recapping a power supply that has a number of these. Ltec's website doesn't seem to mention that series. -
Re: Old HP Pavilion ZE1000 Bios Update
Yeah, post a pic. The product # is what you need, which is different from the model #. You type the product # in at support.hp.com and it will resolve the model number for you. Look for a 6 character code on the label that's not the serial....Leave a comment:

Re: Dell Latitude D530 Milk Incident! Now it does not run from battery...
Check for burnt or shorted MOSFETs in the battery charging circuit. I've found them to be the cause of about 80% of battery charging issues. If it's not that, it's usually a controller chip, and that's a bit harder to find a replacement for.Leave a comment:

Re: MS Office 2007 deactivated itself!
If it's a pirated key, they probably blocked it.
If it's a genuine key, did you change any hardware recently? Sometimes hardware changes can break activation. Heck, I've had bios updates break activation on occasion.
Check your date and time settings as well. I've had that cause issues with activation and windows updates.Leave a comment:

Re: D865GBF with oddball KZG
HM and KZG have identical specifications, so the suggested replacement will work fine.
Cost, most likely. A few cents savings over millions of boards adds up to a lot. I've never had any issues changing the CPU VRM capacitors to polymer.
Elsewhere you have to be a bit careful differing too much from the original specifications. It might work, it might not. Changing this around too much gets into experimentation territory. Furthermore, polymer capacitors tend not to be available in capacitance...Leave a comment:

Re: D865GBF with oddball KZG
Yes. They're on different circuits, so the applications are different. Exact replacements aren't available, so we have to pick the "next best" thing. Given that the circuits are different, the next best things will be different for the two applications.
Take CPU VRM. The original caps are rated for 6.3V. One of the proposed replacements is a 2.5V cap. P4 CPUs run at "about" 1.5V, and that's the voltage on that circuit. Therefore, it's safe to reduce the voltage rating in this case. The 2nd proposed replacement...Leave a comment:

Re: D865GBF with oddball KZG
What brand/series of capacitor is that? My photographic memory is usually pretty good, but that one wasn't bad on my board, so I don't recall what it was. It's possible my board uses a different brand of capacitor there. If it's another KZG, you can use this:

Re: D865GBF with oddball KZG
Which 820uF capacitors? Are they the 23mm tall ones? If so, they're a custom size, and have lower ESR than the standard size ones.
The ones near the CPU, use these:

The HNs up the capacitance a bit, but keep the ESR near the original specs. This is not a problem in a CPU VRM circuit. The...Leave a comment:

Re: Who makes the better monitors
My 24" NEC appears to have Rubycon capacitors in the power supply, from what I can see through the vents. Then again, it is the crazy expensive professional series LCD, so I'd expect it to use good stuff. I previously had Dell/Sony Trinitrons. I was serious about photography at the time, so color accuracy was a priority for me. It's going on 3 years old and I've had zero issues with it, so I've never opened up the case to check out the components in more detail.

Re: My oh my WHAT A DIFFERENCE!
It's not a problem, it's a "feature"... Intellipark as WD calls it was first introduced in the Caviar Green desktop drives. It parks the heads after a ridiculously short period of inactivity. Then it started showing up in laptop drives. So far, I've only seen it in Caviar Blue drives larger than 320 GB. There is a wdidle3 utility that is sometimes successful in disabling the head parking. I've had it work for some drives, and fail to work for others. The aggressive head parking is more of a problem for some systems than for...Leave a comment:

Re: WD Caviar Green HDD failed. Any way to recover files?
Assuming the bios will see the drive, and it sounds like it does, I've had the best luck using GNU ddrescue. It's pretty unique in its implementation in that it reads until it finds and error, skips ahead and reads backwards, etc. Basically, it tries to get as much of the good data as possible, as quickly as possible. You can direct the output of ddrescue to an image file, which you can then mount. Of course, this assumes you have good basic understanding of Linux. I haven't seen a comparable tool for Windows.Leave a comment:

Re: Samsung HDDs
In my experience, they're no better and no worse than any other manufacturer. I prefer Western Digital myself because they have the easiest RMA process by far. I see quite a few Samsungs in newer big box computers and haven't noticed anything abnormal as far as failure rates go. I have a 1TB Spinpoint F1 in my workbench computer because I got it on sale for $49. So far, so good.Leave a comment:

Re: Used Laptop Has No Windows Vista Installation Disks?
I've had no issues using retail Vista discs and the OEM key printed on the label on the laptop. This usually activates fine, but occasionally requires a call to Microsoft. I've never had fail to activate after calling Microsoft.
This assumes that the COA label is still reabable. With Vista, MS switched to uncoated paper labels, and the ink rubs off after awhile. XP didn't have this problem, as the labels were laminated. With Windows 7, most of the OEMs have started putting the COA label inside the battery compartment...Leave a comment:

Re: My Toshiba Satellite A215-S5837 has a cracked B154EW02 V.5 screen
Yes and no. 99% of laptop screens use the same standards for connectors, voltage, etc. Odds are the inverters are perfectly compatible. Desktop LCDs are a different story altogether and don't always have interchangeable components.
If a used screen is dim, it usually means that the backlights don't have a whole lot of life left. I find that older Samsung screens are dim, where as older LG or AUO/Quanta screens stay a bit brighter as they age. These aren't hard and fast rules, just...Leave a comment:

Re: What's the consensus here on copper shims?
I haven't installed one either. In my mind, if it needs a copper shim, there's some serious issues with the cooling design and it's only delaying the inevitable. I keep a good amount of different thicknesses of thermal pads on hand for replacing them in laptops. Thermal paste won't work in these scenarios, as there's too big of a gap to bridge with thermal paste. As long as you use the correct thickness of pad and keep it under pressure, they do a decent job of transferring heat.
My personal laptop is Dell Latitude D620...Leave a comment:
