HP Elitebook 8440p overheating

You can get used 8440p laptops pretty cheaply because HP Elitebook 8440p overheating is rather common. Symptoms of overheating include unexpected reboots, shutting down, and bluescreens.

The problems with the cooling system are unfortunate. They have nice keyboards, they’re easy to work on, and they’re reliable otherwise, so they’d be nice laptops if they didn’t overheat so much. Here’s how to improve their cooling so you can get a bargain–buying off-lease business laptops is a great way to save money.

Digiland tablet review

The Digiland DL718M tablet is an inexpensive (sub-$40) tablet sold at consumer electronics stores like Best Buy. Make no mistake, a Digiland tablet is a basic tablet for basic needs. But given reasonable expectations you can buy one of these and be happy with it.

This isn’t a new market by any stretch. But it seems like tablets in this price range are usually Black Friday specials, or only available on online marketplaces far abroad. The Digiland DL718M, or today’s equivalent, is one you can get today if you want.

How to disassemble a Nook Simple Touch to remove or replace a battery

If your Nook Simple Touch won’t power on, or is displaying a question mark (?) on its battery indicator, I have a four things to try. But before you go to the trouble of disassembly, try charging the device with a different charger. Some chargers fit more tightly than others, and as devices like these age, they can get picky about their chargers.

If a charger change doesn’t give you an easy fix, the next step is to disassemble it, unplug the battery, wait a good 30 seconds, then plug it back in and reassemble.

You’ll need a very small slotted screwdriver or another sharp and semi-flat object, and a T5 Torx screwdriver.

How to open an Asus Memo Pad 7 HD and fix the battery

My son’s Asus Memopad 7 HD would not power up or charge, and my earlier non-invasive solution wouldn’t fix it. Here’s how I opened it up to disconnect and reconnect the battery.

Always try holding the power button and volume down button first because that’s easier (see the link above for details), but if that doesn’t work, proceed to open the case.

While you’re in there, you can also fix an issue that may be causing the power or volume buttons to be hard to press or malfunction entirely. Dropping the tablet a lot makes this happen. If you have young children, you probably understand.

Another malady these tablets can develop is a battery with a question mark when charging. This will sometimes fix that issue as well.

Fixing an Asus Memopad 7 that wouldn’t power on

One night my son ran down the battery on his Memopad 7 and put it away, but didn’t put it on the charger or tell me about it. The next time he went to use it, it was dead.

I tried several different tricks I found online, including plugging it in overnight to the AC adapter, plugging it in overnight to a computer’s USB port, and holding down the power button for a full minute or even a full five minutes. None of it worked–the unit just wouldn’t power on or show any signs of life whatsoever.

Finally I resigned myself to the possibility I would have to send it in for service. Read More »Fixing an Asus Memopad 7 that wouldn’t power on

Curious conspiracies… or maybe just progress all at once

In the wake of Truecrypt’s sudden implosion, someone sent me a link to this curious blog post. I can see why many people might find the timing interesting, but there are a number of details this particular blog post doesn’t get correct, and it actually spends most of its time talking about stuff that has little or nothing to do with Truecrypt.

What’s unclear to me is whether he’s trying to say the industry is deliberately sabotaging Truecrypt, or if he’s simply trying to make a list of things that are making life difficult for Truecrypt. His post bothers me a lot less if it’s just a laundry list of challenges, but either way, the inaccuracies remain.Read More »Curious conspiracies… or maybe just progress all at once

The Asus Memo Pad HD 7 review: It’s a nice inexpensive tablet

I’ve been messing with an Asus Memopad, the 7-inch version. I think it’s a well-built, good-performing tablet for $149, and when you can get it on sale for less than that–and this is the time of year for that–I think it’s a great tablet for the money.

It’s not a high-end tablet. It has a 1280×800 screen, a quad-core 1.2 GHz Mediatek processor, a middling GPU, and 1 GB of RAM, and importantly, it includes a micro SD slot so you can add up to 32 GB of storage to it. The specs are all reasonable, but not mind-blowing. Most of the complaints I’ve seen about it are that it’s not a Nexus 7, but it’s 2/3 the price of a Nexus 7, too. When you compare it to other tablets in its price range, the worst you can say about it is that it holds its own.Read More »The Asus Memo Pad HD 7 review: It’s a nice inexpensive tablet
