Revived ASUS AIO ET2220INTI-I5 – Flickering Screens (Overheating)

Back in June 2013, I did an un-boxing review on the ASUS AIO ET2220. 4 years have since passed, and now it is starting to give a little problem – flickering greenish screens! Based on my test so far, the greenish screen only appeared after some time of usage (like 30 mins or so). And then the screen will then start to flicker until the screen finally turns itself off while the system is still running. And if you were to shut it down and power it up after 15 minutes, the system will be fine again. I then began performing some diagnostics using HWMonitor and found out that the temperature of the onboard graphics Nvidia GT610 had hit a high of 75°C. This is definitely not the norm as it should idle around 50°C and increase to approximately 65°C during load.

So what is the problem? It is likely to be associated either to the cooling system (i.e: heatsink and fan) or the thermal paste losing its effect. I decided to open up the chassis to take a look.

First, you have to remove the 5 rubber seals at the edges, and then remove the screws beneath it. And then remove the plastic cover for the stand and loosen the 4 screws.

          

The next step is to remove the back cover that are secured by the plastic clips. Please do this with care or you might risk breaking the clips as they are very soft. After releasing the back cover from the plastic clips, DO NOT pull the cover out as it it connected to the side ports via a ribbon.

Replace Samsung Galaxy Tab S 8.4 (SM-T700) Battery (EB-BT705FBE)

The Samsung Galaxy Tab S 8.4 (SM-T700) has been one of my favorite gadget for the past year. If you are interested on its specifications, you may refer to my previous write-up. Lately, its battery charge became irregular and sometimes a full charge could only last me 1-2 hours instead of the usual 6-7 hours (subject to my personal usage).

As this tablet’s specifications is still quite decent compared to the current market offerings, I decided to proceed with operation “Tab S 8.4 Battery Replacement“. Do note that the warranty for my tablet is already over.

I headed over to eBay to grab a replacement battery (Model: EB-BT705FBE rated at 4900 mAh) which claimed to be authentic. The battery was shipped from Sweden and cost me approximately USD$16 with free shipping inclusive. The kit came with both the battery and the tools required to open the tablet’s housing.
