Disassemble Guide: How to clean the fan for Acer Aspire 4937G
I’ve been experiencing auto-reboot recently again. Due to overheat I guess.
It’s been half a year since I last clean my laptop fan.
Normal users should clean their fan once a year. But for power users, you may need to clean them more frequently, like twice a year. (like me :S)
DISCLAIMER: If you really wants to disassemble your laptop, DO AT YOUR OWN RISK! I do not, and will not, bear any responsibility of you messing up your own laptop just because you’ve been reading my guide. This is just a basic guideline for experienced users with hardware knowledge. It is advised to send your set to proper technician if you do not feel confident, or do not wish to take the risk. Also, note that opening your laptop case WILL VOID YOUR WARRANTY! (Although it doesn’t really matter, Acer’s after-sales service sucks anyway.)
DISCLAIMER 2: This post is more than 2 years old. Unfortunately, my laptop has long gone, and I am not an Acer technician. Follow this guide at your own risk, and note that I may not be able to answer most of you questions now as I can’t really recall much details anymore. Sorry.
Ok here we go…
First of all, these are the tools you need:
– A small plus (+) sign screwdriver, but not too small. About the size of the screws under your laptop. Preferably magnetic.
– A small minus (-) sign screwdriver, about the size of above plus size screwdriver. Useful for prying open some casings.
– A really small minus (-) sign screwdriver. Useful for opening small plugs.
These are the tools I used this time. (With my Nokia N70 beside for size comparison)
Before you start, shut down your laptop, take out the battery and let it cool down for a while if you’ve been running it for some time. It will be dangerous to operate a hot laptop.
Flip to the bottom of the laptop, and take out all the screws as shown.
Next, open the 3 panels to expose the Harddisc, RAM, and WiFi card. Take out the 2 side cover of the LCD as well.
Take out more screws under it as shown.
Take out the harddisc and RAM as you normally would. Slide the DVD-drive out from the inside. Take out the PCI dummy if you have it. Remember how they connect the WiFi card. It’s white on top and black below. It is advised to take a picture before pulling the plug, so that you can remember how to put them back when you’re done.
Take out the WiFi card when you’re done. Now, flip the laptop, and carefully open the LCD screen. Since the bottom are unscrewed, you may need to hold the sides of the top cover to avoid breaking the top casing, specifically left side (right side have 3 screws beneath, you can worry less.)
Next, carefully pry open the speaker panel.
Once you’re done, you may slot out the keyboard, to reveal the underneath. Take out more screws, and on top of that, plugs. Use your very small sized minus sign screwdriver to open up small plugs before pulling it out.
After all the screws and plugs, take out the speaker and quick-launch board. Time to remove the LCD. Take out 3 more screws under the speaker board, and carefully pull out the black and white wire from below. (I forgot to take a picture, so I will just use back the previous ones.)
Take off the LCD and put it aside. Carefully pry open the top casing to reveal the motherboard underneath. This is going to end soon. Some little more screws and plugs.
Carefully slide out the motherboard. Flip it over. You’ve finally reached the fan! Take out more screws.
Flip over the fan, and clean the layer of dust blocking the ventilation.
It is not necessary to clean the dust in the fan itself, although you may do so if you wish. I don’t do it, since it involve much much smaller screws, and it requires a lot more concentration and proper tools screwing back in.
When you’re done, you generally had done this to your laptop.
Alright, you can start to read this guide in reverse. And wish you good luck. =)
Any questions, just leave me a comment, I will try to answer them if I can. But do not expect too much from me, I am not Acer technician.
粉红？浅紫？傻傻分不清楚～
由于上次只买到一个蓝杯，送给宝贝了。
我自己也很想要一个蓝杯，所以在卖蓝杯的最后一天的最后一个晚上才去排队买。
可是。。。
去了 SS2 的 McD 他们 sold out 了。。。
然后去附近 Bandar Utama 的，也是 Sold out 了。。。
然后去 Damansara Uptown 的，也是 habis。。。
然后去 Mutiara Damansara 两间，也是完了。。。
然后去更远一点的。。。也是没有。。。
打电话去问，他们也是说没有了。。。
来来去去尽了 7～8 间 McD。。。全程用了两格油，
走了大概 20km，还下起了很大很大的雨，要绕路回家因为 banjir。。。
结果。。。黄天不负苦心人，我最后还是没有买到。 =（
谢谢宝贝一直说要送回给我。可是我知道你比较喜欢也比较适合蓝色啦～
你喜欢我就开心了。没有买到蓝杯也没关系的。
才说到没买到蓝杯很显，第二天就轮到卖 pink color 的杯了。
我听颜色看 catalog 其实一开始没有很想要的，
因为我本身就很讨厌 pink color 的东西（除了 sirap bandung 我就喜欢）。
因为同事们要去买杯要去 McD 午餐，所以我也跟住去咯～
本来我只打算去吃吃就算了，可是到那边了的时候。。。
排队超级长的！原来这里很多很多人都要买杯。
看到 counter 那边的杯半打半打卖掉的。 = =+
然后哦。。。当我看在排队看到旁边坐着的人桌上的杯过后。。。
Ei~其实也没有很 pink 很难看嘛～
比较像是浅紫色的嘛～
看了马上就变蛮喜欢掉，就马上 on the spot 改变主意买了个 pink color 的杯。
哈哈～
明天是其中一个世界末日了。
不过不是爱你的终点～
两个乡巴佬
小乡巴佬最后一年最后的考试完了，房子也停租了，
所以要大乡巴佬帮忙载一大堆货下去，暂放大乡巴佬的家，
然后自己带一小堆货回家。
因为星期二是 Wesak Day 假期，
大乡巴佬于是向大城市公司请假一天，
就有了连续四天休息日。陪小乡巴佬在大城市逛逛玩玩。
星期六，大乡巴佬从大城市出发，去小乡巴佬的大学乡下去。
上货，超级多的。还好小红长大变大黑了，不然根本载不完。
在乡下停了一会儿，剪了一头乡巴头，吃了一下乡巴 McD，
就准备回去大乡巴佬的城市去了。
真是的，剪完头发了才知道，那边那个理发店的帅哥们，很多基佬。。。
大乡巴佬的头发被一个不懂是不是基佬的帅哥摸了半天。
= =+
蓝色的可口可乐杯很漂亮。
不愧是乡巴佬们，容易被这种城市里普通的东西吸引。
星期天，两个乡巴佬去了一间很大很大的百货公司。
本来打算在大城市的戏院看看戏的，
可是，好长的人龙哦。。。超级无敌懒惰排队的乡巴佬们，就决定回家，
试试 “新潮” 的网上购票。
其实也才逛了两个小时，就累到要死了。
大城市的百货公司真的是超级大的。
网上购票，原来那么容易的。时代真是进步好快。
晚上去一间甜品店吃晚餐。很可怜，小乡巴佬叫的食物都卖完了。
明明就没什么货，还学人家开店开到那么晚。而且脸臭臭的。
大城市的服务态度怎么都那么差啊，感慨感慨。
花生糊是不是其实很容易做的啊，拿花生酱加水煮就行了？
不然作末花生糊，在 receipt 上面竟然是写 “PEANUT BUTTER”。。。
看电影。乡巴佬第一次网上购票，还以为买到很好的位子。
结果，原来买倒反了。。。所以两个乡巴佬坐在前面前面第二排，一起仰望电影。
“This shit takes off very slowly, it’s a little awkward, goodbye.” — quoted Paul
笑死。
星期一，拿了 leave 的工作日，
两个乡巴佬靠着新科技，一个叫鸡屁爱死的东西，一起去了三位累滚。
其他朋友都只买便宜的蓝表，只有乡巴佬傻傻买贵的 oren 表。
玩水，玩车，玩桥。今天大家都有自己的人生大突破！
大乡巴佬人生突破：被大水桶泼！
小乡巴佬人生突破：走大吊桥！还有坐水龙沟轮胎船。
这里的食物竟然比云顶还贵。我一直都以为云顶的东西是最贵的了。
乡巴佬来打城市，才知道鸡饭是 RM15 一碟的。 @。@
走着走着，又累了。看到附近有东西卖都不能买。
可怜，两个乡巴佬，在大城市走，没钱，不能买吃的。
本来计划的不肥餐被小乡巴佬的城市朋友吃倒闭了，所以晚上去吃韩国餐。
真是的，大家偷偷庆祝小乡巴佬的生日，结果大乡巴佬也不被拖进去庆祝了。
生日快乐～
星期二，小乡巴佬要返乡了。早上就去吃久违了的芝麻糊。
早生贵子，早生胡子。边吃边偷看旁边停小红的 “帅哥”。
去洗照片，结果乡巴佬不会用洗照片的机器，
所洗了两张大大张的照片。多给了几块钱。笨拙死了。
然后还去挤 frozen yogurt ，以为挤了一点点应该没有超过 100 gram，
哪里知道挤到了十多块去。而且招牌口味竟然是臭酸的口味。= =+
乡巴佬果然就是不懂欣赏大城市的健康口味。
还是 chocolate 跟 vanilla 比较好吃。
上楼梯，发现上错楼梯，又下回去。
这种事情好像不是第一次做了。哈哈～
去机场坐巴士回。返乡去。
有缘再见。
