Computer shops say that up to 20 percent of Toshiba laptops
brought in for repair have issues with overheating. Symptoms may be as
simple as the keyboard and bottom of the laptop being very hot while the
computer is working, or the fans running at maximum rotation while the
system becomes very slow for several minutes at a time. More
inconvenient issues are common, such as the system completely seizing up
and having to be "killed" with the battery pulled out, or the computer
may shut down all by itself with no warning. Sometimes the laptop works
fine until the user starts any significant memory-demanding
applications, like photo editing software, several Internet windows
being open at the same time, or an Internet video stream.
A common problem with the Toshiba laptop is that dust
becomes clogged between the cooling fan and the heatsink, a device which
lowers the temperature by dissipating heat into the surrounding air.
Now heat produced by the processor is trapped inside the laptop, and the
fan cannot blow it out.
Every Windows Operating System after Windows 98 can share its Internet Connection using this Technique. Microsoft defines this technique as Internet Connection Sharing (ICS). But setting ICS is very obscure to most of the users. This comes very useful if you live with your roommates and you guys have single internet source like a USB modem Connected to one laptop only. Using Internet Connection Sharing(ICS) that laptop can Broadcast its Internet to other laptops in the room. Technically, the range of a laptop's WLAN adapter is around 20-25 meters. So it can easily handle near by rooms also. This can also be done with a PC having a WLAN card. To setup and broadcast your internet it is mandatory that you are accessing internet using anything other than Your WLAN card like a USB modem, Ethernet etc. This is because your Wireless adapter(WLAN) will be used for Broadcasting your Internet connection to your friends. Server laptop:- Laptop with Internet Connection.Client Laptop:- Laptops accessing the internet of server laptop. Follow the steps to share your internet connection..here it goes:--
Open the "Control Panel" of the laptop that is accessing Internet and go to "Network and Internet" then "Network and Sharing Center".
On the right side of the "Network and Sharing Center" click the "Change Adapter Settings" and you will see all the available network adapters in your laptop.
Now Right-Click the adapter through which you access internet and click "Properties" option. The properties window will open.
In "properies" Window click the "sharing" tab check "Allow other network user to connect through this computer's Internet connection"
In the sharing tab, Select "Home networking connection" type as "Wireless Network Connection" click "OK" and select "Yes" to the Confirmation warning. see above image.
Now Right-Click the "Wireless Network Connection" in "Change Adapter Settings"and Open Its Properties.
In "Wireless Network Connection Properties" Double-click the "Internet Protocol Version 4(TCP/IPv4)" and select the "Use following IP address"
Enter the IP address as "192.168.000.001" and "Subnet mask" as "255.255.255.0"
Leave all other fields blank in Server laptop, which has access to internet.
Now setup a wireless "ad hoc" computer to computer connection using "setup a new connection or network" in "network and sharing center" and Name it as anything like "Internet_sharing".
Now bring other laptops that will use the Shared Internet connection.
Open "Change adapter Setting" (Described in step 2).
In "Change adapter settings" Right-click "wireless Network Adapter" and Click its properties.
In "Wireless Network Connection Properties" Double-click the "Internet Protocol Version 4(TCP/IPv4)" and enter following IP address:-
IP address-"192.168.000.002", Subnet mask "255.255.255.0", Default gateway-"192.168.0.001" and Preferred DNS server: "192.168.000.001".
Use the same step from 11 to 15 to connect other laptops and Increase the IP address by +1. Ex- 192.168.0.3, 192.168.0.4 & so on. Rest of the settings like Default gateway etc will be same on all laptops. Only the server laptop will have blank entries in these settings.
Now connect all the laptop with the Wireless network(ad-hoc) named "Internet-sharing" that you had previously broadcasted in step 10 in server laptop.
Now in the server laptop, disconnect and then reconnect the internet connection(This is a necessary step for Internet Connection sharing(ICS) to work).
Now access internet in all laptops...ENjoy.
Note:- For Advance Users.. this information is necessary only--The IP address of server laptop work as the "Default gateway" and Preferred DNS server of Client laptop and on server laptop these fields are blank. Use same series of IP address as used in the server. please vote if you found this helpful..--Abhishek
is the computer dissipating excessive heat from bottom ? is the heatsink fan working (is it blowing out air from fan on the side ? if not, then replace the heatsink fan. This shut down occurs to advise you that something is not working well , and to avoid damage to the CPU and/or mainboard, its letting you know that.
if the fan is working fine-- are you on the computer while the AC adapter is NOT plugged in ? Are you fully charging the battery before you use the notebook without the AC adapter ? If you are NOT using the AC adapter, running on battery life only, then do this : shut down the notebook, disconnect the power adapter, remove the battery back up from rear of notebook.
reconnect the AC adpater and start the computer -- perform normal function on the computer, run it and work with it for a few hours. if the same issue occurs, (unwanted shut down) , then perhaps the AC adapter is faulty, which is not charging the battery to full capacity.
let me know what happens-- i'd appreciate your feedback w/o receiving bad rating
If you are using the Windows own Wireless connection wizard (Wireless Zero Configuration service aka WZCSVC) this is designed to recheck every 20-30 mins for another connection this is your problem disable the service here download this tweak.
Then download and use the laptop NIC's own software to search for your Uni server and then connect using the WEP or PSK, this will solve your problem then create a profile in the NIC connection software and it will never forget.
To break in a battery for Acer, you have to charge it up, then let it run down completely 3 times! The battery only has a 300 recharge life, so you must never leave it in your Acer when you are plugged in. Use it only when you need a battery, then take it out. Be sure to use it set for battery use, with minimum drain. only recharge it after it is exhausted. It sounds to me as if you bought a bum battery.. Call them, and ask for a replacement.
